+name: browser-edge-cases
+description: SOP for debugging browser automation failures on complex websites. Use when browser tools fail on specific sites like LinkedIn, Twitter/X, SPAs, or sites with Shadow DOM.
+license: MIT
+---
+
+# Browser Tool Edge Cases
+
+Standard Operating Procedure for debugging and fixing browser automation failures on complex websites.
+
+## When to Use This Skill
+
+- `browser_scroll` succeeds but page doesn't move
+- `browser_click` succeeds but no action triggered
+- `browser_type` text disappears or doesn't work
+- `browser_snapshot` hangs or returns stale content
+- `browser_navigate` loads wrong content
+
+## SOP: Debugging Browser Tool Failures
+
+### Phase 1: Reproduce & Isolate
+
+```
+1. Create minimal test case demonstrating failure
+2. Test against simple site (example.com) to verify tool works
+3. Test against problematic site to confirm issue
+```
+
+**Quick isolation test:**
+```python
+# Test 1: Does the tool work at all?
+await browser_navigate(tab_id, "https://example.com")
+result = await browser_scroll(tab_id, "down", 100)
+# Should work on simple sites
+
+# Test 2: Does it fail on the problematic site?
+await browser_navigate(tab_id, "https://linkedin.com/feed")
+result = await browser_scroll(tab_id, "down", 100)
+# If this fails but example.com works → site-specific edge case
+```
+
+### Phase 2: Analyze Root Cause
+
+**Step 2a: Check console for errors**
+```python
+console = await browser_console(tab_id)
+# Look for: CSP violations, React errors, JavaScript exceptions
+```
+
+**Step 2b: Inspect DOM structure**
+```python
+html = await browser_html(tab_id)
+snapshot = await browser_snapshot(tab_id)
+# Look for:
+# - Nested scrollable divs (overflow: scroll/auto)
+# - Shadow DOM roots
+# - iframes
+# - Custom widgets
+```
+
+**Step 2c: Identify the pattern**
+
+| Symptom | Likely Cause | Check |
+|---------|--------------|-------|
+| Scroll doesn't move | Nested scroll container | Look for `overflow: scroll` divs |
+| Click no effect | Element covered | Check `getBoundingClientRect` vs viewport |
+| Type clears | Autocomplete/React | Check for event listeners on input; try `browser_type_focused` |
+| Snapshot hangs | Huge DOM | Check node count in snapshot |
+| Snapshot stale | SPA hydration | Wait after navigation |
+
+### Phase 3: Implement Multi-Layer Fix
+
+**Pattern: Always have fallbacks**
+
+```python
+async def robust_operation(tab_id):
+    # Method 1: Primary approach
+    try:
+        result = await primary_method(tab_id)
+        if verify_success(result):
+            return result
+    except Exception:
+        pass
+
+    # Method 2: CDP fallback
+    try:
+        result = await cdp_fallback(tab_id)
+        if verify_success(result):
+            return result
+    except Exception:
+        pass
+
+    # Method 3: JavaScript fallback
+    return await javascript_fallback(tab_id)
+```
+
+**Pattern: Always add timeouts**
+
+```python
+# Bad - can hang forever
+result = await browser_snapshot(tab_id)
+
+# Good - fails fast with useful error
+try:
+    result = await browser_snapshot(tab_id, timeout_s=10.0)
+except asyncio.TimeoutError:
+    # Handle timeout gracefully
+    result = await fallback_snapshot(tab_id)
+```
+
+### Phase 4: Verify Fix
+
+```
+1. Run against problematic site → should work
+2. Run against simple site → should still work (regression check)
+3. Document in registry.md
+```
+
+## Pattern Library
+
+### P1: Nested Scrollable Containers
+
+**Sites:** LinkedIn, Twitter/X, any SPA with scrollable feeds
+
+**Detection:**
+```javascript
+// Find largest scrollable container
+const candidates = [];
+document.querySelectorAll('*').forEach(el => {
+    const style = getComputedStyle(el);
+    if (style.overflow.includes('scroll') || style.overflow.includes('auto')) {
+        const rect = el.getBoundingClientRect();
+        if (rect.width > 100 && rect.height > 100) {
+            candidates.push({el, area: rect.width * rect.height});
+        }
+    }
+});
+candidates.sort((a, b) => b.area - a.area);
+return candidates[0]?.el;
+```
+
+**Fix:** Dispatch scroll events at container's center, not viewport center.
+
+### P2: Element Covered by Overlay
+
+**Sites:** Modals, tooltips, SPAs with loading overlays
+
+**Detection:**
+```javascript
+const rect = element.getBoundingClientRect();
+const centerX = rect.left + rect.width / 2;
+const centerY = rect.top + rect.height / 2;
+const topElement = document.elementFromPoint(centerX, centerY);
+return topElement === element || element.contains(topElement);
+```
+
+**Fix:** Wait for overlay to disappear, or use JavaScript click.
+
+### P3: React Synthetic Events
+
+**Sites:** React SPAs, modern web apps
+
+**Detection:** If CDP click doesn't trigger handler but manual click works.
+
+**Fix:** Use JavaScript click as primary:
+```javascript
+element.click();
+```
+
+### P4: Huge DOM / Accessibility Tree
+
+**Sites:** LinkedIn, Facebook, Twitter (feeds with 1000s of nodes)
+
+**Detection:**
+```javascript
+document.querySelectorAll('*').length > 5000
+```
+
+**Fix:**
+1. Add timeout to snapshot operation
+2. Truncate tree at 2000 nodes
+3. Fall back to DOM-based snapshot if accessibility tree too large
+
+### P5: SPA Hydration Delay
+
+**Sites:** React, Vue, Angular SPAs after navigation
+
+**Detection:**
+```javascript
+// Check if React app has hydrated
+document.querySelector('[data-reactroot]') ||
+document.querySelector('[data-reactid]')
+```
+
+**Fix:** Wait for specific selector after navigation:
+```python
+await browser_navigate(tab_id, url, wait_until="load")
+await browser_wait(tab_id, selector='[data-testid="content"]', timeout_ms=5000)
+```
+
+### P6: Shadow DOM
+
+**Sites:** Components using Shadow DOM, Lit elements
+
+**Detection:**
+```javascript
+document.querySelectorAll('*').some(el => el.shadowRoot)
+```
+
+**Fix:** Pierce shadow root:
+```javascript
+function queryShadow(selector) {
+    const parts = selector.split('>>>');
+    let node = document;
+    for (const part of parts) {
+        if (node.shadowRoot) {
+            node = node.shadowRoot.querySelector(part.trim());
+        } else {
+            node = node.querySelector(part.trim());
+        }
+    }
+    return node;
+}
+```
+
+## Quick Reference
+
+| Issue | Primary Fix | Fallback |
+|-------|-------------|----------|
+| Scroll not working | Find scrollable container | Mouse wheel at container center |
+| Click no effect | JavaScript click() | CDP mouse events |
+| Type clears | Add delay_ms | Use `browser_type_focused` (Input.insertText) |
+| Snapshot hangs | Add timeout_s | DOM snapshot fallback |
+| Stale content | Wait for selector | Increase wait_until timeout |
+| Shadow DOM | Pierce selector | JavaScript traversal |

+
+## Scroll Issues
+
+### #1: LinkedIn Nested Scroll Container
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | LinkedIn (linkedin.com/feed) |
+| **Symptom** | `browser_scroll()` returns `{ok: true}` but page doesn't move |
+| **Root Cause** | Content is in a nested scrollable div (`overflow: scroll`), not the main window |
+| **Detection** | `document.querySelectorAll('*')` with `overflow: scroll/auto` has large candidates |
+| **Fix** | JavaScript finds largest scrollable container, uses `container.scrollBy()` |
+| **Code** | `bridge.py:808-891` - smart scroll with container detection |
+| **Verified** | 2026-04-03 ✓ |
+
+### #2: Twitter/X Lazy Loading
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Twitter/X (x.com) |
+| **Symptom** | Infinite scroll doesn't load new content |
+| **Root Cause** | Lazy loading requires content to be visible before loading more |
+| **Detection** | Scroll position at bottom but no new `[data-testid="tweet"]` elements |
+| **Fix** | Add `wait_for_selector` between scroll calls with 1s delay |
+| **Code** | Test file: `tests/test_x_page_load_repro.py` |
+| **Verified** | - |
+
+### #3: Modal/Dialog Scroll Container
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Any site with modal dialogs |
+| **Symptom** | Scroll scrolls background page, not modal content |
+| **Root Cause** | Modal has its own scroll container with `overflow: scroll` |
+| **Detection** | Visible element with `position: fixed` and scrollable content |
+| **Fix** | Find visible modal container (highest z-index scrollable), scroll that |
+| **Code** | - |
+| **Verified** | - |
+
+---
+
+## Click Issues
+
+### #4: Element Covered by Overlay
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | SPAs, sites with loading overlays |
+| **Symptom** | Click succeeds but no action triggered |
+| **Root Cause** | Element is covered by transparent overlay, tooltip, or iframe |
+| **Detection** | `document.elementFromPoint(x, y) !== target` |
+| **Fix** | Wait for overlay to disappear, or use JavaScript `element.click()` |
+| **Code** | `bridge.py:394-591` - JavaScript click as primary |
+| **Verified** | - |
+
+### #5: React Synthetic Events
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | React applications |
+| **Symptom** | CDP click doesn't trigger React handler |
+| **Root Cause** | React uses synthetic events that don't respond to CDP events |
+| **Detection** | Site uses React (check for `__reactFiber$` or `data-reactroot`) |
+| **Fix** | Use JavaScript `element.click()` as primary method |
+| **Code** | `bridge.py:394-591` - JavaScript-first click |
+| **Verified** | - |
+
+### #6: Shadow DOM Elements
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Components using Shadow DOM, Lit elements |
+| **Symptom** | `querySelector` can't find element |
+| **Root Cause** | Element is inside a shadow root, not main DOM tree |
+| **Detection** | `element.shadowRoot !== null` on parent elements |
+| **Fix** | Use piercing selector (`host >>> target`) or traverse shadow roots |
+| **Code** | See SKILL.md P6 pattern |
+| **Verified** | 2026-04-03 ✓ |
+
+---
+
+## Input Issues
+
+### #7: ContentEditable / Rich Text Editors
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Rich text editors (Notion, Slack web, etc.) |
+| **Symptom** | `browser_type()` doesn't insert text |
+| **Root Cause** | Element is `contenteditable`, not an `<input>` or `<textarea>` |
+| **Detection** | `element.contentEditable === 'true'` |
+| **Fix** | Focus via JavaScript, use `execCommand('insertText')` or `Input.dispatchKeyEvent` |
+| **Code** | `bridge.py:616-694` - contentEditable handling |
+| **Verified** | 2026-04-03 ✓ |
+
+### #8: Autocomplete Field Clearing
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Search fields with autocomplete, address forms |
+| **Symptom** | Typed text gets cleared immediately |
+| **Root Cause** | Field expects realistic keystroke timing for autocomplete |
+| **Detection** | Field has autocomplete listeners or dropdown appears |
+| **Fix** | Add `delay_ms=50` between keystrokes |
+| **Code** | `bridge.py:type()` - delay_ms parameter |
+| **Verified** | 2026-04-03 ✓ |
+
+### #9: Custom Date Pickers
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Forms with custom date widgets |
+| **Symptom** | Can't type date into date field |
+| **Root Cause** | Custom widget intercepts and blocks keyboard input |
+| **Detection** | Typing doesn't change field value |
+| **Fix** | Click calendar widget icon, select date from dropdown |
+| **Code** | - |
+| **Verified** | - |
+
+---
+
+## Snapshot Issues
+
+### #10: LinkedIn Huge DOM Tree
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | LinkedIn, Facebook, Twitter feeds |
+| **Symptom** | `browser_snapshot()` hangs forever |
+| **Root Cause** | 10k+ DOM nodes, accessibility tree has 50k+ nodes |
+| **Detection** | `document.querySelectorAll('*').length > 5000` |
+| **Fix** | Add `timeout_s` param with `asyncio.timeout()`, proper error handling |
+| **Code** | `bridge.py:1041-1028` - snapshot with timeout protection |
+| **Verified** | 2026-04-03 ✓ (0.08s on LinkedIn) |
+
+### #11: SPA Hydration Delay
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | React/Vue/Angular SPAs |
+| **Symptom** | Snapshot shows old content after navigation |
+| **Root Cause** | Client-side hydration hasn't completed when snapshot runs |
+| **Detection** | `document.readyState === 'complete'` but content missing |
+| **Fix** | Wait for specific selector after navigation |
+| **Code** | Test file: `tests/test_x_page_load_repro.py` |
+| **Verified** | - |
+
+### #12: iframe Content Missing
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Sites with embedded content |
+| **Symptom** | Snapshot missing iframe content |
+| **Root Cause** | Accessibility tree doesn't include iframe content |
+| **Detection** | `document.querySelectorAll('iframe')` has results |
+| **Fix** | Use `DOM.getFrameOwner` + separate snapshot for each iframe |
+| **Code** | - |
+| **Verified** | - |
+
+---
+
+## Navigation Issues
+
+### #13: SPA Navigation Events
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | React Router, Vue Router SPAs |
+| **Symptom** | `wait_until="load"` fires before content ready |
+| **Root Cause** | SPA uses client-side routing, no full page load |
+| **Detection** | URL changes but `load` event already fired |
+| **Fix** | Use `wait_until="networkidle"` or `wait_for_selector` |
+| **Code** | `bridge.py:navigate()` - wait_until options |
+| **Verified** | - |
+
+### #14: Cross-Origin Redirects
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | OAuth flows, SSO logins |
+| **Symptom** | Navigation fails during redirect |
+| **Root Cause** | Cross-origin security prevents CDP tracking |
+| **Detection** | URL changes to different domain |
+| **Fix** | Use `wait_for_url` with pattern matching instead of exact URL |
+| **Code** | - |
+| **Verified** | - |
+

+
+## Screenshot Issues
+
+### #15: Selector Screenshot Not Implemented
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Any site |
+| **Symptom** | `browser_screenshot(selector="h1")` takes full viewport instead of element |
+| **Root Cause** | `selector` param existed in signature but was silently ignored in both `bridge.py` and `inspection.py` |
+| **Detection** | Screenshot with selector same byte size as screenshot without selector |
+| **Fix** | Use CDP `Runtime.evaluate` to call `getBoundingClientRect()` on the element, pass result as `clip` to `Page.captureScreenshot` |
+| **Code** | `bridge.py:1315-1344` - selector clip logic; `inspection.py:94-96` - pass selector to bridge |
+| **Verified** | 2026-04-03 ✓ (JS rect query returns correct viewport coords; requires server restart) |
+
+### #16: Stale Browser Context (Group ID Mismatch)
+
+| Attribute | Value |
+|-----------|-------|
+| **Site** | Any |
+| **Symptom** | `browser_open()` returns `"No group with id: XXXXXXX"` even though `browser_status` shows `running: true` |
+| **Root Cause** | In-memory `_contexts` dict has a stale `groupId` from a Chrome tab group that was closed outside the tool (e.g. user closed the tab group) |
+| **Detection** | `browser_status` returns `running: true` but `browser_open` fails with "No group with id" |
+| **Fix** | Call `browser_stop()` to clear stale context from `_contexts`, then `browser_start()` again |
+| **Code** | `tools/lifecycle.py:144-160` - `already_running` check uses cached dict without validating against Chrome |
+| **Verified** | 2026-04-03 ✓ |

-# Building Agents - Core Concepts
-
-Foundational knowledge for building goal-driven agents as Python packages.
-
-## Architecture: Python Services (Not JSON Configs)
-
-Agents are built as Python packages:
-
-```
-exports/my_agent/
-├── __init__.py          # Package exports
-├── __main__.py          # CLI (run, info, validate, shell)
-├── agent.py             # Graph construction (goal, edges, agent class)
-├── nodes/__init__.py    # Node definitions (NodeSpec)
-├── config.py            # Runtime config
-└── README.md            # Documentation
-```
-
-**Key Principle: Agent is visible and editable during build**
-
- Files created immediately as components are approved
- User can watch files grow in their editor
- No session state - just direct file writes
- No "export" step - agent is ready when build completes
-
-## Core Concepts
-
-### Goal
-
-Success criteria and constraints (written to agent.py)
-
-```python
-goal = Goal(
-    id="research-goal",
-    name="Technical Research Agent",
-    description="Research technical topics thoroughly",
-    success_criteria=[
-        SuccessCriterion(
-            id="completeness",
-            description="Cover all aspects of topic",
-            metric="coverage_score",
-            target=">=0.9",
-            weight=0.4,
-        ),
-        # 3-5 success criteria total
-    ],
-    constraints=[
-        Constraint(
-            id="accuracy",
-            description="All information must be verified",
-            constraint_type="hard",
-            category="quality",
-        ),
-        # 1-5 constraints total
-    ],
-)
-```
-
-### Node
-
-Unit of work (written to nodes/__init__.py)
-
-**Node Types:**
-
- `event_loop` — Multi-turn streaming loop with tool execution and judge-based evaluation. Works with or without tools.
- `function` — Deterministic Python operations. No LLM involved.
-
-```python
-search_node = NodeSpec(
-    id="search-web",
-    name="Search Web",
-    description="Search for information and extract results",
-    node_type="event_loop",
-    input_keys=["query"],
-    output_keys=["search_results"],
-    system_prompt="Search the web for: {query}. Use the web_search tool to find results, then call set_output to store them.",
-    tools=["web_search"],
-)
-```
-
-**NodeSpec Fields for Event Loop Nodes:**
-
-| Field | Default | Description |
-|-------|---------|-------------|
-| `client_facing` | `False` | If True, streams output to user and blocks for input between turns |
-| `nullable_output_keys` | `[]` | Output keys that may remain unset (for mutually exclusive outputs) |
-| `max_node_visits` | `1` | Max times this node executes per run. Set >1 for feedback loop targets |
-
-### Edge
-
-Connection between nodes (written to agent.py)
-
-**Edge Conditions:**
-
- `on_success` — Proceed if node succeeds (most common)
- `on_failure` — Handle errors
- `always` — Always proceed
- `conditional` — Based on expression evaluating node output
-
-**Edge Priority:**
-
-Priority controls evaluation order when multiple edges leave the same node. Higher priority edges are evaluated first. Use negative priority for feedback edges (edges that loop back to earlier nodes).
-
-```python
-# Forward edge (evaluated first)
-EdgeSpec(
-    id="review-to-campaign",
-    source="review",
-    target="campaign-builder",
-    condition=EdgeCondition.CONDITIONAL,
-    condition_expr="output.get('approved_contacts') is not None",
-    priority=1,
-)
-
-# Feedback edge (evaluated after forward edges)
-EdgeSpec(
-    id="review-feedback",
-    source="review",
-    target="extractor",
-    condition=EdgeCondition.CONDITIONAL,
-    condition_expr="output.get('redo_extraction') is not None",
-    priority=-1,
-)
-```
-
-### Client-Facing Nodes
-
-For multi-turn conversations with the user, set `client_facing=True` on a node. The node will:
- Stream its LLM output directly to the end user
- Block for user input between conversational turns
- Resume when new input is injected via `inject_event()`
-
-```python
-intake_node = NodeSpec(
-    id="intake",
-    name="Intake",
-    description="Gather requirements from the user",
-    node_type="event_loop",
-    client_facing=True,
-    input_keys=[],
-    output_keys=["repo_url", "project_url"],
-    system_prompt="You are the intake agent. Ask the user for the repo URL and project URL.",
-)
-```
-
-> **Legacy Note:** The old `pause_nodes` / `entry_points` pattern still works but `client_facing=True` is preferred for new agents.
-
-**STEP 1 / STEP 2 Prompt Pattern:** For client-facing nodes, structure the system prompt with two explicit phases:
-
-```python
-system_prompt="""\
-**STEP 1 — Respond to the user (text only, NO tool calls):**
-[Present information, ask questions, etc.]
-
-**STEP 2 — After the user responds, call set_output:**
-[Call set_output with the structured outputs]
-"""
-```
-
-This prevents the LLM from calling `set_output` prematurely before the user has had a chance to respond.
-
-### Node Design: Fewer, Richer Nodes
-
-Prefer fewer nodes that do more work over many thin single-purpose nodes:
-
- **Bad**: 8 thin nodes (parse query → search → fetch → evaluate → synthesize → write → check → save)
- **Good**: 4 rich nodes (intake → research → review → report)
-
-Why: Each node boundary requires serializing outputs and passing context. Fewer nodes means the LLM retains full context of its work within the node. A research node that searches, fetches, and analyzes keeps all the source material in its conversation history.
-
-### nullable_output_keys for Cross-Edge Inputs
-
-When a node receives inputs that only arrive on certain edges (e.g., `feedback` only comes from a review → research feedback loop, not from intake → research), mark those keys as `nullable_output_keys`:
-
-```python
-research_node = NodeSpec(
-    id="research",
-    input_keys=["research_brief", "feedback"],
-    nullable_output_keys=["feedback"],  # Not present on first visit
-    max_node_visits=3,
-    ...
-)
-```
-
-## Event Loop Architecture Concepts
-
-### How EventLoopNode Works
-
-An event loop node runs a multi-turn loop:
-1. LLM receives system prompt + conversation history
-2. LLM responds (text and/or tool calls)
-3. Tool calls are executed, results added to conversation
-4. Judge evaluates: ACCEPT (exit loop), RETRY (loop again), or ESCALATE
-5. Repeat until judge ACCEPTs or max_iterations reached
-
-### EventLoopNode Runtime
-
-EventLoopNodes are **auto-created** by `GraphExecutor` at runtime. You do NOT need to manually register them. Both `GraphExecutor` (direct) and `AgentRuntime` / `create_agent_runtime()` handle event_loop nodes automatically.
-
-```python
-# Direct execution — executor auto-creates EventLoopNodes
-from framework.graph.executor import GraphExecutor
-from framework.runtime.core import Runtime
-
-runtime = Runtime(storage_path)
-executor = GraphExecutor(
-    runtime=runtime,
-    llm=llm,
-    tools=tools,
-    tool_executor=tool_executor,
-    storage_path=storage_path,
-)
-result = await executor.execute(graph=graph, goal=goal, input_data=input_data)
-
-# TUI execution — AgentRuntime also works
-from framework.runtime.agent_runtime import create_agent_runtime
-runtime = create_agent_runtime(
-    graph=graph, goal=goal, storage_path=storage_path,
-    entry_points=[...], llm=llm, tools=tools, tool_executor=tool_executor,
-)
-```
-
-### set_output
-
-Nodes produce structured outputs by calling `set_output(key, value)` — a synthetic tool injected by the framework. When the LLM calls `set_output`, the value is stored in the output accumulator and made available to downstream nodes via shared memory.
-
-`set_output` is NOT a real tool — it is excluded from `real_tool_results`. For client-facing nodes, this means a turn where the LLM only calls `set_output` (no other tools) is treated as a conversational boundary and will block for user input.
-
-### JudgeProtocol
-
-**The judge is the SOLE mechanism for acceptance decisions.** Do not add ad-hoc framework gating, output rollback, or premature rejection logic. If the LLM calls `set_output` too early, fix it with better prompts or a custom judge — not framework-level guards.
-
-The judge controls when a node's loop exits:
- **Implicit judge** (default, no judge configured): ACCEPTs when the LLM finishes with no tool calls and all required output keys are set
- **SchemaJudge**: Validates outputs against a Pydantic model
- **Custom judges**: Implement `evaluate(context) -> JudgeVerdict`
-
-### LoopConfig
-
-Controls loop behavior:
- `max_iterations` (default 50) — prevents infinite loops
- `max_tool_calls_per_turn` (default 10) — limits tool calls per LLM response
- `tool_call_overflow_margin` (default 0.5) — wiggle room before discarding extra tool calls (50% means hard cutoff at 150% of limit)
- `stall_detection_threshold` (default 3) — detects repeated identical responses
- `max_history_tokens` (default 32000) — triggers conversation compaction
-
-### Data Tools (Spillover Management)
-
-When tool results exceed the context window, the framework automatically saves them to a spillover directory and truncates with a hint. Nodes that produce or consume large data should include the data tools:
-
- `save_data(filename, data)` — Write data to a file in the data directory
- `load_data(filename, offset=0, limit=50)` — Read data with line-based pagination
- `list_data_files()` — List available data files
- `serve_file_to_user(filename, label="")` — Get a clickable file:// URI for the user
-
-Note: `data_dir` is a framework-injected context parameter — the LLM never sees or passes it. `GraphExecutor.execute()` sets it per-execution via `contextvars`, so data tools and spillover always share the same session-scoped directory.
-
-These are real MCP tools (not synthetic). Add them to nodes that handle large tool results:
-
-```python
-research_node = NodeSpec(
-    ...
-    tools=["web_search", "web_scrape", "load_data", "save_data", "list_data_files"],
-)
-```
-
-### Fan-Out / Fan-In
-
-Multiple ON_SUCCESS edges from the same source create parallel execution. All branches run concurrently via `asyncio.gather()`. Parallel event_loop nodes must have disjoint `output_keys`.
-
-### max_node_visits
-
-Controls how many times a node can execute in one graph run. Default is 1. Set higher for nodes that are targets of feedback edges (review-reject loops). Set 0 for unlimited (guarded by max_steps).
-
-## Tool Discovery & Validation
-
-**CRITICAL:** Before adding a node with tools, you MUST verify the tools exist.
-
-Tools are provided by MCP servers. Never assume a tool exists - always discover dynamically.
-
-### Step 1: Register MCP Server (if not already done)
-
-```python
-mcp__agent-builder__add_mcp_server(
-    name="tools",
-    transport="stdio",
-    command="python",
-    args='["mcp_server.py", "--stdio"]',
-    cwd="../tools"
-)
-```
-
-### Step 2: Discover Available Tools
-
-```python
-# List all tools from all registered servers
-mcp__agent-builder__list_mcp_tools()
-
-# Or list tools from a specific server
-mcp__agent-builder__list_mcp_tools(server_name="tools")
-```
-
-### Step 3: Validate Before Adding Nodes
-
-Before writing a node with `tools=[...]`:
-
-1. Call `list_mcp_tools()` to get available tools
-2. Check each tool in your node exists in the response
-3. If a tool doesn't exist:
-   - **DO NOT proceed** with the node
-   - Inform the user: "The tool 'X' is not available. Available tools are: ..."
-   - Ask if they want to use an alternative or proceed without the tool
-
-### Tool Validation Anti-Patterns
-
- **Never assume a tool exists** - always call `list_mcp_tools()` first
- **Never write a node with unverified tools** - validate before writing
- **Never silently drop tools** - if a tool doesn't exist, inform the user
- **Never guess tool names** - use exact names from discovery response
-
-## Workflow Overview: Incremental File Construction
-
-```
-1. CREATE PACKAGE → mkdir + write skeletons
-2. DEFINE GOAL → Write to agent.py + config.py
-3. FOR EACH NODE:
-   - Propose design (event_loop for LLM work, function for deterministic)
-   - User approves
-   - Write to nodes/__init__.py IMMEDIATELY
-   - (Optional) Validate with test_node
-4. CONNECT EDGES → Update agent.py
-   - Use priority for feedback edges (negative priority)
-   - (Optional) Validate with validate_graph
-5. FINALIZE → Write agent class to agent.py
-6. DONE - Agent ready at exports/my_agent/
-```
-
-**Files written immediately. MCP tools optional for validation/testing bookkeeping.**
-
-## When to Use This Skill
-
-Use hive-concepts when:
- Starting a new agent project and need to understand fundamentals
- Need to understand agent architecture before building
- Want to validate tool availability before proceeding
- Learning about node types, edges, and graph execution
-
-**Next Steps:**
- Ready to build? → Use `hive-create` skill
- Need patterns and examples? → Use `hive-patterns` skill
-
-## MCP Tools for Validation
-
-After writing files, optionally use MCP tools for validation:
-
-**test_node** - Validate node configuration with mock inputs
-```python
-mcp__agent-builder__test_node(
-    node_id="search-web",
-    test_input='{"query": "test query"}',
-    mock_llm_response='{"results": "mock output"}'
-)
-```
-
-**validate_graph** - Check graph structure
-```python
-mcp__agent-builder__validate_graph()
-# Returns: unreachable nodes, missing connections, event_loop validation, etc.
-```
-
-**configure_loop** - Set event loop parameters
-```python
-mcp__agent-builder__configure_loop(
-    max_iterations=50,
-    max_tool_calls_per_turn=10,
-    stall_detection_threshold=3,
-    max_history_tokens=32000
-)
-```
-
-**Key Point:** Files are written FIRST. MCP tools are for validation only.

-# Agent Construction - EXECUTE THESE STEPS
-
-**THIS IS AN EXECUTABLE WORKFLOW. DO NOT DISPLAY THIS FILE. EXECUTE THE STEPS BELOW.**
-
-**CRITICAL: DO NOT explore the codebase, read source files, or search for code before starting.** All context you need is in this skill file. When this skill is loaded, IMMEDIATELY begin executing Step 0 — determine the build path as your FIRST action. Do not explain what you will do, do not investigate the project structure, do not read any files — just execute Step 0 now.
-
---
-
-## STEP 0: Choose Build Path
-
-**If the user has already indicated whether they want to build from scratch or from a template, skip this question and proceed to the appropriate step.**
-
-Otherwise, ask:
-
-```
-AskUserQuestion(questions=[{
-    "question": "How would you like to build your agent?",
-    "header": "Build Path",
-    "options": [
-        {"label": "From scratch", "description": "Design goal, nodes, and graph collaboratively from nothing"},
-        {"label": "From a template", "description": "Start from a working sample agent and customize it"}
-    ],
-    "multiSelect": false
-}])
-```
-
- If **From scratch**: Proceed to STEP 1A
- If **From a template**: Proceed to STEP 1B
-
---
-
-## STEP 1A: Initialize Build Environment (From Scratch)
-
-**EXECUTE THESE TOOL CALLS NOW** (silent setup — no user interaction needed):
-
-1. Check for existing sessions:
-
-```
-mcp__agent-builder__list_sessions()
-```
-
- If a session with this agent name already exists, load it with `mcp__agent-builder__load_session_by_id(session_id="...")` and skip to step 3.
- If no matching session exists, proceed to step 2.
-
-2. Create a build session (replace AGENT_NAME with the user's requested agent name in snake_case):
-
-```
-mcp__agent-builder__create_session(name="AGENT_NAME")
-```
-
-3. Register the hive-tools MCP server:
-
-```
-mcp__agent-builder__add_mcp_server(
-    name="hive-tools",
-    transport="stdio",
-    command="uv",
-    args='["run", "python", "mcp_server.py", "--stdio"]',
-    cwd="tools",
-    description="Hive tools MCP server"
-)
-```
-
-4. Discover available tools:
-
-```
-mcp__agent-builder__list_mcp_tools()
-```
-
-5. Create the package directory:
-
-```bash
-mkdir -p exports/AGENT_NAME/nodes
-```
-
-**Save the tool list for STEP 4** — you will need it for node design.
-
-**THEN immediately proceed to STEP 2** (do NOT display setup results to the user — just move on).
-
---
-
-## STEP 1B: Initialize Build Environment (From Template)
-
-**EXECUTE THESE STEPS NOW:**
-
-### 1B.1: Discover available templates
-
-List the template directories and read each template's `agent.json` to get its name and description:
-
-```bash
-ls examples/templates/
-```
-
-For each directory found, read `examples/templates/TEMPLATE_DIR/agent.json` with the Read tool and extract:
- `agent.name` — the template's display name
- `agent.description` — what the template does
-
-### 1B.2: Present templates to user
-
-Show the user a table of available templates:
-
-> **Available Templates:**
->
-> | # | Template | Description |
-> |---|----------|-------------|
-> | 1 | [name from agent.json] | [description from agent.json] |
-> | 2 | ... | ... |
-
-Then ask the user to pick a template and provide a name for their new agent:
-
-```
-AskUserQuestion(questions=[{
-    "question": "Which template would you like to start from?",
-    "header": "Template",
-    "options": [
-        {"label": "[template 1 name]", "description": "[template 1 description]"},
-        {"label": "[template 2 name]", "description": "[template 2 description]"},
-        ...
-    ],
-    "multiSelect": false
-}, {
-    "question": "What should the new agent be named? (snake_case)",
-    "header": "Agent Name",
-    "options": [
-        {"label": "Use template name", "description": "Keep the original template name as-is"},
-        {"label": "Custom name", "description": "I'll provide a new snake_case name"}
-    ],
-    "multiSelect": false
-}])
-```
-
-### 1B.3: Copy template to exports
-
-```bash
-cp -r examples/templates/TEMPLATE_DIR exports/NEW_AGENT_NAME
-```
-
-### 1B.4: Create session and register MCP (same logic as STEP 1A)
-
-First, check for existing sessions:
-
-```
-mcp__agent-builder__list_sessions()
-```
-
- If a session with this agent name already exists, load it with `mcp__agent-builder__load_session_by_id(session_id="...")` and skip to `list_mcp_tools`.
- If no matching session exists, create one:
-
-```
-mcp__agent-builder__create_session(name="NEW_AGENT_NAME")
-```
-
-Then register MCP and discover tools:
-
-```
-mcp__agent-builder__add_mcp_server(
-    name="hive-tools",
-    transport="stdio",
-    command="uv",
-    args='["run", "python", "mcp_server.py", "--stdio"]',
-    cwd="tools",
-    description="Hive tools MCP server"
-)
-```
-
-```
-mcp__agent-builder__list_mcp_tools()
-```
-
-### 1B.5: Load template into builder session
-
-Import the entire agent definition in one call:
-
-```
-mcp__agent-builder__import_from_export(agent_json_path="exports/NEW_AGENT_NAME/agent.json")
-```
-
-This reads the agent.json and populates the builder session with the goal, all nodes, and all edges.
-
-**THEN immediately proceed to STEP 2.**
-
---
-
-## STEP 2: Define Goal Together with User
-**A responsible engineer doesn't jump into building. First, understand the problem and be transparent about what the framework can and cannot do.**
-
-**If starting from a template**, the goal is already loaded in the builder session. Present the existing goal to the user using the format below and ask for approval. Skip the collaborative drafting questions — go straight to presenting and asking "Do you approve this goal, or would you like to modify it?"
-
-**If the user has NOT already described what they want to build**, start by asking what kind of agent they have in mind:
-
-```
-AskUserQuestion(questions=[{
-    "question": "What kind of agent do you want to build? Select an option below, or choose 'Other' to describe your own.",
-    "header": "Agent type",
-    "options": [
-        {"label": "Data collection", "description": "Gathers information from the web, analyzes it, and produces a report or sends outreach (e.g. market research, news digest, email campaigns, competitive analysis)"},
-        {"label": "Workflow automation", "description": "Automates a multi-step business process end-to-end (e.g. lead qualification, content publishing pipeline, data entry)"},
-        {"label": "Personal assistant", "description": "Handles recurring tasks or monitors for events and acts on them (e.g. daily briefings, meeting prep, file organization)"}
-    ],
-    "multiSelect": false
-}])
-```
-
-Use the user's selection (or their custom description if they chose "Other") as context when shaping the goal below. If the user already described what they want before this step, skip the question and proceed directly.
-
-**DO NOT propose a complete goal on your own.** Instead, collaborate with the user to define it.
-
-### 2a: Fast Discovery (3-8 Turns)
-
-**The core principle**: Discovery should feel like progress, not paperwork. The stakeholder should walk away feeling like you understood them faster than anyone else would have.
-
-**Communication sytle**: Be concise. Say less. Mean more. Impatient stakeholders don't want a wall of text — they want to know you get it. Every sentence you say should either move the conversation forward or prove you understood something. If it does neither, cut it.
-
-**Ask Question Rules: Respect Their Time.** Every question must earn its place by:
-1. **Preventing a costly wrong turn** — you're about to build the wrong thing
-2. **Unlocking a shortcut** — their answer lets you simplify the design
-3. **Surfacing a dealbreaker** — there's a constraint that changes everything
-4. **Provide Options** - Provide options to your questions if possible, but also always allow the user to type something beyong the options.
-
-If a question doesn't do one of these, don't ask it. Make an assumption, state it, and move on.
-
---
-
-#### 2a.1: Let Them Talk, But Listen Like an Architect
-
-When the stakeholder describes what they want, don't just hear the words — listen for the architecture underneath. While they talk, mentally construct:
-
- **The actors**: Who are the people/systems involved?
- **The trigger**: What kicks off the workflow?
- **The core loop**: What's the main thing that happens repeatedly?
- **The output**: What's the valuable thing produced at the end?
- **The pain**: What about today's situation is broken, slow, or missing?
-
-You are extracting a **domain model** from natural language in real time. Most stakeholders won't give you this structure explicitly — they'll give you a story. Your job is to hear the structure inside the story.
-
-| They say... | You're hearing... |
-|-------------|-------------------|
-| Nouns they repeat | Your entities |
-| Verbs they emphasize | Your core operations |
-| Frustrations they mention | Your design constraints |
-| Workarounds they describe | What the system must replace |
-| People they name | Your user types |
-
---
-
-#### 2a.2: Use Domain Knowledge to Fill In the Blanks
-
-You have broad knowledge of how systems work. Use it aggressively.
-
-If they say "I need a research agent," you already know it probably involves: search, summarization, source tracking, and iteration. Don't ask about each — use them as your starting mental model and let their specifics override your defaults.
-
-If they say "I need to monitor files and alert me," you know this probably involves: watch patterns, triggers, notifications, and state tracking.
-
-**The key move**: Take your general knowledge of the domain and merge it with the specifics they've given you. The result is a draft understanding that's 60-80% right before you've asked a single question. Your questions close the remaining 20-40%.

-
-#### 2a.3: Play Back a Proposed Model (Not a List of Questions)
-
-After listening, present a **concrete picture** of what you think they need. Make it specific enough that they can spot what's wrong.
-
-**Pattern: "Here's what I heard — tell me where I'm off"**
-
-> "OK here's how I'm picturing this: [User type] needs to [core action]. Right now they're [current painful workflow]. What you want is [proposed solution that replaces the pain].
->
-> The way I'd structure this: [key entities] connected by [key relationships], with the main flow being [trigger → steps → outcome].
->
-> For the MVP, I'd focus on [the one thing that delivers the most value] and hold off on [things that can wait].
->
-> Before I start — [1-2 specific questions you genuinely can't infer]."
-
-Why this works:
- **Proves you were listening** — they don't feel like they have to repeat themselves
- **Shows competence** — you're already thinking in systems
- **Fast to correct** — "no, it's more like X" takes 10 seconds vs. answering 15 questions
- **Creates momentum** — heading toward building, not more talking
-
---
-
-#### 2a.4: Ask Only What You Cannot Infer
-
-Your questions should be **narrow, specific, and consequential**. Never ask what you could answer yourself.
-
-**Good questions** (high-stakes, can't infer):
- "Who's the primary user — you or your end customers?"
- "Is this replacing a spreadsheet, or is there literally nothing today?"
- "Does this need to integrate with anything, or standalone?"
- "Is there existing data to migrate, or starting fresh?"
-
-**Bad questions** (low-stakes, inferable):
- "What should happen if there's an error?" *(handle gracefully, obviously)*
- "Should it have search?" *(if there's a list, yes)*
- "How should we handle permissions?" *(follow standard patterns)*
- "What tools should I use?" *(your call, not theirs)*
-
---
-
-#### Conversation Flow (3-5 Turns)
-
-| Turn | Who | What |
-|------|-----|------|
-| 1 | User | Describes what they need |
-| 2 | Agent | Plays back understanding as a proposed model. Asks 1-2 critical questions max. |
-| 3 | User | Corrects, confirms, or adds detail |
-| 4 | Agent | Adjusts model, confirms MVP scope, states assumptions, declares starting point |
-| *(5)* | *(Only if Turn 3 revealed something that fundamentally changes the approach)* |
-
-**AFTER the conversation, IMMEDIATELY proceed to 2b. DO NOT skip to building.**
-
---
-
-#### Anti-Patterns
-
-| Don't | Do Instead |
-|-------|------------|
-| Open with a list of questions | Open with what you understood from their request |
-| "What are your requirements?" | "Here's what I think you need — am I right?" |
-| Ask about every edge case | Handle with smart defaults, flag in summary |
-| 10+ turn discovery conversation | 3-8 turns. Start building, iterate with real software. |
-| Being lazy nd not understand what user want to achieve | Understand "what" and "why |
-| Ask for permission to start | State your plan and start |
-| Wait for certainty | Start at 80% confidence, iterate the rest |
-| Ask what tech/tools to use | That's your job. Decide, disclose, move on. |

-### 2b: Capability Assessment
-
-**After the user responds, analyze the fit.** Present this assessment honestly:
-
-> **Framework Fit Assessment**
->
-> Based on what you've described, here's my honest assessment of how well this framework fits your use case:
->
-> **What Works Well (The Good):**
-> - [List 2-4 things the framework handles well for this use case]
-> - Examples: multi-turn conversations, human-in-the-loop review, tool orchestration, structured outputs
->
-> **Limitations to Be Aware Of (The Bad):**
-> - [List 2-3 limitations that apply but are workable]
-> - Examples: LLM latency means not suitable for sub-second responses, context window limits for very large documents, cost per run for heavy tool usage
->
-> **Potential Deal-Breakers (The Ugly):**
-> - [List any significant challenges or missing capabilities — be honest]
-> - Examples: no tool available for X, would require custom MCP server, framework not designed for Y
-
-**Be specific.** Reference the actual tools discovered in Step 1. If the user needs `send_email` but it's not available, say so. If they need real-time streaming from a database, explain that's not how the framework works.
-
-### 2c: Gap Analysis
-
-**Identify specific gaps** between what the user wants and what you can deliver:
-
-| Requirement | Framework Support | Gap/Workaround |
-|-------------|-------------------|----------------|
-| [User need] | [✅ Supported / ⚠️ Partial / ❌ Not supported] | [How to handle or why it's a problem] |
-
-**Examples of gaps to identify:**
- Missing tools (user needs X, but only Y and Z are available)
- Scope issues (user wants to process 10,000 items, but LLM rate limits apply)
- Interaction mismatches (user wants CLI-only, but agent is designed for TUI)
- Data flow issues (user needs to persist state across runs, but sessions are isolated)
- Latency requirements (user needs instant responses, but LLM calls take seconds)
-
-### 2d: Recommendation
-
-**Give a clear recommendation:**
-
-> **My Recommendation:**
->
-> [One of these three:]
->
-> **✅ PROCEED** — This is a good fit. The framework handles your core needs well. [List any minor caveats.]
->
-> **⚠️ PROCEED WITH SCOPE ADJUSTMENT** — This can work, but we should adjust: [specific changes]. Without these adjustments, you'll hit [specific problems].
->
-> **🛑 RECONSIDER** — This framework may not be the right tool for this job because [specific reasons]. Consider instead: [alternatives — simpler script, different framework, custom solution].
-
-### 2e: Get Explicit Acknowledgment
-
-**CALL AskUserQuestion:**
-
-```
-AskUserQuestion(questions=[{
-    "question": "Based on this assessment, how would you like to proceed?",
-    "header": "Proceed",
-    "options": [
-        {"label": "Proceed as described", "description": "I understand the limitations, let's build it"},
-        {"label": "Adjust scope", "description": "Let's modify the requirements to fit better"},
-        {"label": "More questions", "description": "I have questions about the assessment"},
-        {"label": "Reconsider", "description": "Maybe this isn't the right approach"}
-    ],
-    "multiSelect": false
-}])
-```
-
-**WAIT for user response.**
-
- If **Proceed**: Move to STEP 3
- If **Adjust scope**: Discuss what to change, update your notes, re-assess if needed
- If **More questions**: Answer them honestly, then ask again
- If **Reconsider**: Discuss alternatives. If they decide to proceed anyway, that's their informed choice
-

-
-## STEP 3: Define Goal Together with User
-
-**Now that the use case is qualified, collaborate on the goal definition.**
-
-**START by synthesizing what you learned:**
-
-> Based on our discussion, here's my understanding of the goal:
->
-> **Core purpose:** [what you understood from 2a]
-> **Success looks like:** [what you inferred]
-> **Key constraints:** [what you inferred]
->
-> Let me refine this with you:
->
-> 1. **What should this agent accomplish?** (confirm or correct my understanding)
-> 2. **How will we know it succeeded?** (what specific outcomes matter)
-> 3. **Are there any hard constraints?** (things it must never do, quality bars)
-
-**WAIT for the user to respond.** Use their input (and the agent type they selected) to draft:
-
- Goal ID (kebab-case)
- Goal name
- Goal description
- 3-5 success criteria (each with: id, description, metric, target, weight)
- 2-4 constraints (each with: id, description, constraint_type, category)
-
-**PRESENT the draft goal for approval:**
-
-> **Proposed Goal: [Name]**
->
-> [Description]
->
-> **Success Criteria:**
->
-> 1. [criterion 1]
-> 2. [criterion 2]
->    ...
->
-> **Constraints:**
->
-> 1. [constraint 1]
-> 2. [constraint 2]
->    ...
-
-**THEN call AskUserQuestion:**
-
-```
-AskUserQuestion(questions=[{
-    "question": "Do you approve this goal definition?",
-    "header": "Goal",
-    "options": [
-        {"label": "Approve", "description": "Goal looks good, proceed to workflow design"},
-        {"label": "Modify", "description": "I want to change something"}
-    ],
-    "multiSelect": false
-}])
-```
-
-**WAIT for user response.**
-
- If **Approve**: Call `mcp__agent-builder__set_goal(...)` with the goal details, then proceed to STEP 4
- If **Modify**: Ask what they want to change, update the draft, ask again
-
---
-
-## STEP 4: Design Conceptual Nodes
-
-**If starting from a template**, the nodes are already loaded in the builder session. Present the existing nodes using the table format below and ask for approval. Skip the design phase.
-
-**BEFORE designing nodes**, review the available tools from Step 1. Nodes can ONLY use tools that exist.
-
-**DESIGN the workflow** as a series of nodes. For each node, determine:
-
- node_id (kebab-case)
- name
- description
- node_type: `"event_loop"` (recommended for all LLM work) or `"function"` (deterministic, no LLM)
- input_keys (what data this node receives)
- output_keys (what data this node produces)
- tools (ONLY tools that exist from Step 1 — empty list if no tools needed)
- client_facing: True if this node interacts with the user
- nullable_output_keys (for mutually exclusive outputs or feedback-only inputs)
- max_node_visits (>1 if this node is a feedback loop target)
-
-**Prefer fewer, richer nodes** (4 nodes > 8 thin nodes). Each node boundary requires serializing outputs. A research node that searches, fetches, and analyzes keeps all source material in its conversation history.
-
-**PRESENT the nodes to the user for review:**
-
-> **Proposed Nodes ([N] total):**
->
-> | #   | Node ID    | Type       | Description                   | Tools                  | Client-Facing |
-> | --- | ---------- | ---------- | ----------------------------- | ---------------------- | :-----------: |
-> | 1   | `intake`   | event_loop | Gather requirements from user | —                      |      Yes      |
-> | 2   | `research` | event_loop | Search and analyze sources    | web_search, web_scrape |      No       |
-> | 3   | `review`   | event_loop | Present findings for approval | —                      |      Yes      |
-> | 4   | `report`   | event_loop | Generate final report         | save_data              |      No       |
->
-> **Data Flow:**
->
-> - `intake` produces: `research_brief`
-> - `research` receives: `research_brief` → produces: `findings`, `sources`
-> - `review` receives: `findings`, `sources` → produces: `approved_findings` or `feedback`
-> - `report` receives: `approved_findings` → produces: `final_report`
-
-**THEN call AskUserQuestion:**
-
-```
-AskUserQuestion(questions=[{
-    "question": "Do you approve these nodes?",
-    "header": "Nodes",
-    "options": [
-        {"label": "Approve", "description": "Nodes look good, proceed to graph design"},
-        {"label": "Modify", "description": "I want to change the nodes"}
-    ],
-    "multiSelect": false
-}])
-```
-
-**WAIT for user response.**
-
- If **Approve**: Proceed to STEP 5
- If **Modify**: Ask what they want to change, update design, ask again
-
---
-
-## STEP 5: Design Full Graph and Review
-
-**If starting from a template**, the edges are already loaded in the builder session. Render the existing graph as ASCII art and present it to the user for approval. Skip the edge design phase.
-
-**DETERMINE the edges** connecting the approved nodes. For each edge:
-
- edge_id (kebab-case)
- source → target
- condition: `on_success`, `on_failure`, `always`, or `conditional`
- condition_expr (Python expression, only if conditional)
- priority (positive = forward, negative = feedback/loop-back)
-
-**RENDER the complete graph as ASCII art.** Make it large and clear — the user needs to see and understand the full workflow at a glance.
-
-**IMPORTANT: Make the ASCII art BIG and READABLE.** Use a box-and-arrow style with generous spacing. Do NOT make it tiny or compressed. Example format:

-**WAIT for user response.**
-
- If **Approve**: Proceed to STEP 6
- If **Modify**: Ask what they want to change, update the graph, re-render, ask again
-
---
-
-## STEP 6: Build the Agent
-
-**NOW — and only now — write the actual code.** The user has approved the goal, nodes, and graph.
-
-### 6a: Register nodes and edges with MCP
-**If starting from a template**, the copied files will be overwritten with the approved design. You MUST replace every occurrence of the old template name with the new agent name. Here is the complete checklist — miss NONE of these:
-
-| File | What to rename |
-|------|---------------|
-| `config.py` | `AgentMetadata.name` — the display name shown in TUI agent selection |
-| `config.py` | `AgentMetadata.description` — agent description |
-| `config.py` | `AgentMetadata.intro_message` — greeting shown to user when TUI loads |
-| `agent.py` | Module docstring (line 1) |
-| `agent.py` | `class OldNameAgent:` → `class NewNameAgent:` |
-| `agent.py` | `GraphSpec(id="old-name-graph")` → `GraphSpec(id="new-name-graph")` — shown in TUI status bar |
-| `agent.py` | Storage path: `Path.home() / ".hive" / "agents" / "old_name"` → `"new_name"` |
-| `__main__.py` | Module docstring (line 1) |
-| `__main__.py` | `from .agent import ... OldNameAgent` → `NewNameAgent` |
-| `__main__.py` | CLI help string in `def cli()` docstring |
-| `__main__.py` | All `OldNameAgent()` instantiations |
-| `__main__.py` | Storage path (duplicated from agent.py) |
-| `__main__.py` | Shell banner string (e.g. `"=== Old Name Agent ==="`) |
-| `__init__.py` | Package docstring |
-| `__init__.py` | `from .agent import OldNameAgent` import |
-| `__init__.py` | `__all__` list entry |
-
-**If starting from a template and no modifications were made in Steps 2-5**, the nodes and edges are already registered. Skip to validation (`mcp__agent-builder__validate_graph()`). If modifications were made, re-register the changed nodes/edges (the MCP tools handle duplicates by overwriting).
-
-**FOR EACH approved node**, call:
-
-```
-mcp__agent-builder__add_node(
-    node_id="...",
-    name="...",
-    description="...",
-    node_type="event_loop",
-    input_keys='["key1", "key2"]',
-    output_keys='["key1"]',
-    tools='["tool1"]',
-    system_prompt="...",
-    client_facing=True/False,
-    nullable_output_keys='["key"]',
-    max_node_visits=1
-)
-```
-
-**FOR EACH approved edge**, call:
-
-```
-mcp__agent-builder__add_edge(
-    edge_id="source-to-target",
-    source="source-node-id",
-    target="target-node-id",
-    condition="on_success",
-    condition_expr="",
-    priority=1
-)
-```
-
-**VALIDATE the graph:**
-
-```
-mcp__agent-builder__validate_graph()
-```
-
- If invalid: Fix the issues and re-validate
- If valid: Continue to 6b
-
-### 6b: Write Python package files
-
-**EXPORT the graph data:**
-
-```
-mcp__agent-builder__export_graph()
-```
-
-**THEN write the Python package files** using the exported data. Create these files in `exports/AGENT_NAME/`:
-
-1. `config.py` - Runtime configuration with model settings and `AgentMetadata` (including `intro_message` — the greeting shown when TUI loads)
-2. `nodes/__init__.py` - All NodeSpec definitions
-3. `agent.py` - Goal, edges, graph config, and agent class
-4. `__init__.py` - Package exports
-5. `__main__.py` - CLI interface
-6. `mcp_servers.json` - MCP server configurations
-7. `README.md` - Usage documentation
-
-**IMPORTANT entry_points format:**
-
- MUST be: `{"start": "first-node-id"}`
- NOT: `{"first-node-id": ["input_keys"]}` (WRONG)
- NOT: `{"first-node-id"}` (WRONG - this is a set)
-
-**IMPORTANT mcp_servers.json format:**
-
-```json
-{
-  "hive-tools": {
-    "transport": "stdio",
-    "command": "uv",
-    "args": ["run", "python", "mcp_server.py", "--stdio"],
-    "cwd": "../../tools",
-    "description": "Hive tools MCP server"
-  }
-}
-```
-
- NO `"mcpServers"` wrapper (that's Claude Desktop format, NOT hive format)
- `cwd` MUST be `"../../tools"` (relative from `exports/AGENT_NAME/` to `tools/`)
- `command` MUST be `"uv"` with `"args": ["run", "python", ...]` (NOT bare `"python"` which fails on Mac)
-
-**Use the example agent** at `.claude/skills/hive-create/examples/deep_research_agent/` as a template for file structure and patterns. It demonstrates: STEP 1/STEP 2 prompts, client-facing nodes, feedback loops, nullable_output_keys, and data tools.
-
-**AFTER writing all files, tell the user:**
-
-> Agent package created: `exports/AGENT_NAME/`
->
-> **Files generated:**
->
-> - `__init__.py` - Package exports
-> - `agent.py` - Goal, nodes, edges, agent class
-> - `config.py` - Runtime configuration
-> - `__main__.py` - CLI interface
-> - `nodes/__init__.py` - Node definitions
-> - `mcp_servers.json` - MCP server config
-> - `README.md` - Usage documentation
-
---
-
-## STEP 7: Verify and Test
-
-**RUN validation:**
-
-```bash
-cd /home/timothy/oss/hive && PYTHONPATH=exports uv run python -m AGENT_NAME validate
-```
-
- If valid: Agent is complete!
- If errors: Fix the issues and re-run
-
-**TELL the user the agent is ready** and display the next steps box:

-## REFERENCE: Node Types
-
-| Type         | tools param             | Use when                                |
-| ------------ | ----------------------- | --------------------------------------- |
-| `event_loop` | `'["tool1"]'` or `'[]'` | LLM-powered work with or without tools  |
-| `function`   | N/A                     | Deterministic Python operations, no LLM |
-
---
-
-## REFERENCE: NodeSpec Fields
-
-| Field                  | Default | Description                                                           |
-| ---------------------- | ------- | --------------------------------------------------------------------- |
-| `client_facing`        | `False` | Streams output to user, blocks for input between turns                |
-| `nullable_output_keys` | `[]`    | Output keys that may remain unset (mutually exclusive outputs)        |
-| `max_node_visits`      | `1`     | Max executions per run. Set >1 for feedback loop targets. 0=unlimited |
-
---
-
-## REFERENCE: Edge Conditions & Priority
-
-| Condition     | When edge is followed                 |
-| ------------- | ------------------------------------- |
-| `on_success`  | Source node completed successfully    |
-| `on_failure`  | Source node failed                    |
-| `always`      | Always, regardless of success/failure |
-| `conditional` | When condition_expr evaluates to True |
-
-**Priority:** Positive = forward edge (evaluated first). Negative = feedback edge (loops back to earlier node). Multiple ON_SUCCESS edges from same source = parallel execution (fan-out).
-
---
-
-## REFERENCE: System Prompt Best Practice
-
-For **internal** event_loop nodes (not client-facing), instruct the LLM to use `set_output`:
-
-```
-Use set_output(key, value) to store your results. For example:
- set_output("search_results", <your results as a JSON string>)
-
-Do NOT return raw JSON. Use the set_output tool to produce outputs.
-```
-
-For **client-facing** event_loop nodes, use the STEP 1/STEP 2 pattern:
-
-```
-**STEP 1 — Respond to the user (text only, NO tool calls):**
-[Present information, ask questions, etc.]
-
-**STEP 2 — After the user responds, call set_output:**
- set_output("key", "value based on user's response")
-```
-
-This prevents the LLM from calling `set_output` before the user has had a chance to respond. The "NO tool calls" instruction in STEP 1 ensures the node blocks for user input before proceeding.
-
---
-
-## EventLoopNode Runtime
-
-EventLoopNodes are **auto-created** by `GraphExecutor` at runtime. Both direct `GraphExecutor` and `AgentRuntime` / `create_agent_runtime()` handle event_loop nodes automatically. No manual `node_registry` setup is needed.
-
-```python
-# Direct execution
-from framework.graph.executor import GraphExecutor
-from framework.runtime.core import Runtime
-
-storage_path = Path.home() / ".hive" / "agents" / "my_agent"
-storage_path.mkdir(parents=True, exist_ok=True)
-runtime = Runtime(storage_path)
-
-executor = GraphExecutor(
-    runtime=runtime,
-    llm=llm,
-    tools=tools,
-    tool_executor=tool_executor,
-    storage_path=storage_path,
-)
-result = await executor.execute(graph=graph, goal=goal, input_data=input_data)
-```
-
-**DO NOT pass `runtime=None` to `GraphExecutor`** — it will crash with `'NoneType' object has no attribute 'start_run'`.

-## REFERENCE: Framework Capabilities for Qualification
-
-Use this reference during STEP 2 to give accurate, honest assessments.
-
-### What the Framework Does Well (The Good)
-
-| Capability | Description |
-|------------|-------------|
-| Multi-turn conversations | Client-facing nodes stream to users and block for input |
-| Human-in-the-loop review | Approval checkpoints with feedback loops back to earlier nodes |
-| Tool orchestration | LLM can call multiple tools, framework handles execution |
-| Structured outputs | `set_output` produces validated, typed outputs |
-| Parallel execution | Fan-out/fan-in for concurrent node execution |
-| Context management | Automatic compaction and spillover for large data |
-| Error recovery | Retry logic, judges, and feedback edges for self-correction |
-| Session persistence | State saved to disk, resumable sessions |
-
-### Framework Limitations (The Bad)
-
-| Limitation | Impact | Workaround |
-|------------|--------|------------|
-| LLM latency | 2-10+ seconds per turn | Not suitable for real-time/low-latency needs |
-| Context window limits | ~128K tokens max | Use data tools for spillover, design for chunking |
-| Cost per run | LLM API calls cost money | Budget planning, caching where possible |
-| Rate limits | API throttling on heavy usage | Backoff, queue management |
-| Node boundaries lose context | Outputs must be serialized | Prefer fewer, richer nodes |
-| Single-threaded within node | One LLM call at a time per node | Use fan-out for parallelism |
-
-### Not Designed For (The Ugly)
-
-| Use Case | Why It's Problematic | Alternative |
-|----------|---------------------|-------------|
-| Long-running daemons | Framework is request-response, not persistent | External scheduler + agent |
-| Sub-second responses | LLM latency is inherent | Traditional code, no LLM |
-| Processing millions of items | Context windows and rate limits | Batch processing + sampling |
-| Real-time streaming data | No built-in pub/sub or streaming input | Custom MCP server + agent |
-| Guaranteed determinism | LLM outputs vary | Function nodes for deterministic parts |
-| Offline/air-gapped | Requires LLM API access | Local models (not currently supported) |
-| Multi-user concurrency | Single-user session model | Separate agent instances per user |
-
-### Tool Availability Reality Check
-
-**Before promising any capability, check `list_mcp_tools()`.** Common gaps:
-
- **Email**: May not have `send_email` — check before promising email automation
- **Calendar**: May not have calendar APIs — check before promising scheduling
- **Database**: May not have SQL tools — check before promising data queries
- **File system**: Has data tools but not arbitrary filesystem access
- **External APIs**: Depends entirely on what MCP servers are registered
-
---
-
-## COMMON MISTAKES TO AVOID
-
-1. **Skipping use case qualification** - A responsible engineer qualifies the use case BEFORE building. Be transparent about what works, what doesn't, and what's problematic
-2. **Hiding limitations** - Don't oversell the framework. If a tool doesn't exist or a capability is missing, say so upfront
-3. **Using tools that don't exist** - Always check `mcp__agent-builder__list_mcp_tools()` first
-4. **Wrong entry_points format** - Must be `{"start": "node-id"}`, NOT a set or list
-5. **Skipping validation** - Always validate nodes and graph before proceeding
-6. **Not waiting for approval** - Always ask user before major steps
-7. **Displaying this file** - Execute the steps, don't show documentation
-8. **Too many thin nodes** - Prefer fewer, richer nodes (4 nodes > 8 nodes)
-9. **Missing STEP 1/STEP 2 in client-facing prompts** - Client-facing nodes need explicit phases to prevent premature set_output
-10. **Forgetting nullable_output_keys** - Mark input_keys that only arrive on certain edges (e.g., feedback) as nullable on the receiving node
-11. **Adding framework gating for LLM behavior** - Fix prompts or use judges, not ad-hoc code
-12. **Writing code before user approves the graph** - Always get approval on goal, nodes, and graph BEFORE writing any agent code
-13. **Wrong mcp_servers.json format** - Use flat format (no `"mcpServers"` wrapper), `cwd` must be `"../../tools"`, and `command` must be `"uv"` with args `["run", "python", ...]`

-
-# Setup Credentials
-
-Interactive credential setup for agents with multiple authentication options. Detects what's missing, offers auth method choices, validates with health checks, and stores credentials securely.
-
-## When to Use
-
- Before running or testing an agent for the first time
- When `AgentRunner.run()` fails with "missing required credentials"
- When a user asks to configure credentials for an agent
- After building a new agent that uses tools requiring API keys
-
-## Workflow
-
-### Step 1: Identify the Agent
-
-Determine which agent needs credentials. The user will either:
-
- Name the agent directly (e.g., "set up credentials for hubspot-agent")
- Have an agent directory open (check `exports/` for agent dirs)
- Be working on an agent in the current session
-
-Locate the agent's directory under `exports/{agent_name}/`.
-
-### Step 2: Detect Missing Credentials
-
-Use the `check_missing_credentials` MCP tool to detect what the agent needs and what's already configured. This tool loads the agent, inspects its required tools and node types, maps them to credentials via `CREDENTIAL_SPECS`, and checks both the encrypted store and environment variables.
-
-```
-check_missing_credentials(agent_path="exports/{agent_name}")
-```
-
-The tool returns a JSON response:
-
-```json
-{
-  "agent": "exports/{agent_name}",
-  "missing": [
-    {
-      "credential_name": "brave_search",
-      "env_var": "BRAVE_SEARCH_API_KEY",
-      "description": "Brave Search API key for web search",
-      "help_url": "https://brave.com/search/api/",
-      "tools": ["web_search"]
-    }
-  ],
-  "available": [
-    {
-      "credential_name": "anthropic",
-      "env_var": "ANTHROPIC_API_KEY",
-      "source": "encrypted_store"
-    }
-  ],
-  "total_missing": 1,
-  "ready": false
-}
-```
-
-**If `ready` is true (nothing missing):** Report all credentials as configured and skip Steps 3-5. Example:
-
-```
-All required credentials are already configured:
-  ✓ anthropic (ANTHROPIC_API_KEY)
-  ✓ brave_search (BRAVE_SEARCH_API_KEY)
-Your agent is ready to run!
-```
-
-**If credentials are missing:** Continue to Step 3 with the `missing` list.
-
-### Step 3: Present Auth Options for Each Missing Credential
-
-For each missing credential, check what authentication methods are available:
-
-```python
-from aden_tools.credentials import CREDENTIAL_SPECS
-
-spec = CREDENTIAL_SPECS.get("hubspot")
-if spec:
-    # Determine available auth options
-    auth_options = []
-    if spec.aden_supported:
-        auth_options.append("aden")
-    if spec.direct_api_key_supported:
-        auth_options.append("direct")
-    auth_options.append("custom")  # Always available
-
-    # Get setup info
-    setup_info = {
-        "env_var": spec.env_var,
-        "description": spec.description,
-        "help_url": spec.help_url,
-        "api_key_instructions": spec.api_key_instructions,
-    }
-```
-
-Present the available options using AskUserQuestion:
-
-```
-Choose how to configure HUBSPOT_ACCESS_TOKEN:
-
-  1) Aden Platform (OAuth) (Recommended)
-     Secure OAuth2 flow via hive.adenhq.com
-     - Quick setup with automatic token refresh
-     - No need to manage API keys manually
-
-  2) Direct API Key
-     Enter your own API key manually
-     - Requires creating a HubSpot Private App
-     - Full control over scopes and permissions
-
-  3) Local Credential Setup (Advanced)
-     Programmatic configuration for CI/CD
-     - For automated deployments
-     - Requires manual API calls
-```
-
-### Step 4: Execute Auth Flow Based on User Choice
-
-#### Prerequisite: Ensure HIVE_CREDENTIAL_KEY Is Available
-
-Before storing any credentials, verify `HIVE_CREDENTIAL_KEY` is set (needed to encrypt/decrypt the local store). Check both the current session and shell config:
-
-```bash
-# Check current session
-printenv HIVE_CREDENTIAL_KEY > /dev/null 2>&1 && echo "session: set" || echo "session: not set"
-
-# Check shell config files
-for f in ~/.zshrc ~/.bashrc ~/.profile; do [ -f "$f" ] && grep -q 'HIVE_CREDENTIAL_KEY' "$f" && echo "$f"; done
-```
-
- **In current session** — proceed to store credentials
- **In shell config but NOT in current session** — run `source ~/.zshrc` (or `~/.bashrc`) first, then proceed
- **Not set anywhere** — `EncryptedFileStorage` will auto-generate one. After storing, tell the user to persist it: `export HIVE_CREDENTIAL_KEY="{generated_key}"` in their shell profile
-
-> **⚠️ IMPORTANT: After adding `HIVE_CREDENTIAL_KEY` to the user's shell config, always display:**
-> ```
-> ⚠️  Environment variables were added to your shell config.
->     Open a NEW TERMINAL for them to take effect outside this session.
-> ```
-
-#### Option 1: Aden Platform (OAuth)
-
-This is the recommended flow for supported integrations (HubSpot, etc.).
-
-**How Aden OAuth Works:**
-
-The ADEN_API_KEY represents a user who has already completed OAuth authorization on Aden's platform. When users sign up and connect integrations on Aden, those OAuth tokens are stored server-side. Having an ADEN_API_KEY means:
-
-1. User has an Aden account
-2. User has already authorized integrations (HubSpot, etc.) via OAuth on Aden
-3. We just need to sync those credentials down to the local credential store
-
-**4.1a. Check for ADEN_API_KEY**
-
-```python
-import os
-aden_key = os.environ.get("ADEN_API_KEY")
-```
-
-If not set, guide user to get one from Aden (this is where they do OAuth):
-
-```python
-from aden_tools.credentials import open_browser, get_aden_setup_url
-
-# Open browser to Aden - user will sign up and connect integrations there
-url = get_aden_setup_url()  # https://hive.adenhq.com
-success, msg = open_browser(url)
-
-print("Please sign in to Aden and connect your integrations (HubSpot, etc.).")
-print("Once done, copy your API key and return here.")
-```
-
-Ask user to provide the ADEN_API_KEY they received.
-
-**4.1b. Save ADEN_API_KEY to Shell Config**
-
-With user approval, persist ADEN_API_KEY to their shell config:
-
-```python
-from aden_tools.credentials import (
-    detect_shell,
-    add_env_var_to_shell_config,
-    get_shell_source_command,
-)
-
-shell_type = detect_shell()  # 'bash', 'zsh', or 'unknown'
-
-# Ask user for approval before modifying shell config
-# If approved:
-success, config_path = add_env_var_to_shell_config(
-    "ADEN_API_KEY",
-    user_provided_key,
-    comment="Aden Platform (OAuth) API key"
-)
-
-if success:
-    source_cmd = get_shell_source_command()
-    print(f"Saved to {config_path}")
-    print(f"Run: {source_cmd}")
-```
-
-> **⚠️ IMPORTANT: After adding `ADEN_API_KEY` to the user's shell config, always display:**
-> ```
-> ⚠️  Environment variables were added to your shell config.
->     Open a NEW TERMINAL for them to take effect outside this session.
-> ```
-
-Also save to `~/.hive/configuration.json` for the framework:
-
-```python
-import json
-from pathlib import Path
-
-config_path = Path.home() / ".hive" / "configuration.json"
-config = json.loads(config_path.read_text()) if config_path.exists() else {}
-
-config["aden"] = {
-    "api_key_configured": True,
-    "api_url": "https://api.adenhq.com"
-}
-
-config_path.parent.mkdir(parents=True, exist_ok=True)
-config_path.write_text(json.dumps(config, indent=2))
-```
-
-**4.1c. Sync Credentials from Aden Server**
-
-Since the user has already authorized integrations on Aden, use the one-liner factory method:
-
-```python
-from core.framework.credentials import CredentialStore
-
-# This single call handles everything:
-# - Creates encrypted local storage at ~/.hive/credentials
-# - Configures Aden client from ADEN_API_KEY env var
-# - Syncs all credentials from Aden server automatically
-store = CredentialStore.with_aden_sync(
-    base_url="https://api.adenhq.com",
-    auto_sync=True,  # Syncs on creation
-)
-
-# Check what was synced
-synced = store.list_credentials()
-print(f"Synced credentials: {synced}")
-
-# If the required credential wasn't synced, the user hasn't authorized it on Aden yet
-if "hubspot" not in synced:
-    print("HubSpot not found in your Aden account.")
-    print("Please visit https://hive.adenhq.com to connect HubSpot, then try again.")
-```
-
-For more control over the sync process:
-
-```python
-from core.framework.credentials import CredentialStore
-from core.framework.credentials.aden import (
-    AdenCredentialClient,
-    AdenClientConfig,
-    AdenSyncProvider,
-)
-
-# Create client (API key loaded from ADEN_API_KEY env var)
-client = AdenCredentialClient(AdenClientConfig(
-    base_url="https://api.adenhq.com",
-))
-
-# Create provider and store
-provider = AdenSyncProvider(client=client)
-store = CredentialStore.with_encrypted_storage()
-
-# Manual sync
-synced_count = provider.sync_all(store)
-print(f"Synced {synced_count} credentials from Aden")
-```
-
-**4.1d. Run Health Check**
-
-```python
-from aden_tools.credentials import check_credential_health
-
-# Get the token from the store
-cred = store.get_credential("hubspot")
-token = cred.keys["access_token"].value.get_secret_value()
-
-result = check_credential_health("hubspot", token)
-if result.valid:
-    print("HubSpot credentials validated successfully!")
-else:
-    print(f"Validation failed: {result.message}")
-    # Offer to retry the OAuth flow
-```
-
-#### Option 2: Direct API Key
-
-For users who prefer manual API key management.
-
-**4.2a. Show Setup Instructions**
-
-```python
-from aden_tools.credentials import CREDENTIAL_SPECS
-
-spec = CREDENTIAL_SPECS.get("hubspot")
-if spec and spec.api_key_instructions:
-    print(spec.api_key_instructions)
-# Output:
-# To get a HubSpot Private App token:
-# 1. Go to HubSpot Settings > Integrations > Private Apps
-# 2. Click "Create a private app"
-# 3. Name your app (e.g., "Hive Agent")
-# ...
-
-if spec and spec.help_url:
-    print(f"More info: {spec.help_url}")
-```
-
-**4.2b. Collect API Key from User**
-
-Use AskUserQuestion to securely collect the API key:
-
-```
-Please provide your HubSpot access token:
-(This will be stored securely in ~/.hive/credentials)
-```
-
-**4.2c. Run Health Check Before Storing**
-
-```python
-from aden_tools.credentials import check_credential_health
-
-result = check_credential_health("hubspot", user_provided_token)
-if not result.valid:
-    print(f"Warning: {result.message}")
-    # Ask user if they want to:
-    # 1. Try a different token
-    # 2. Continue anyway (not recommended)
-```
-
-**4.2d. Store in Local Encrypted Store**
-
-```python
-from core.framework.credentials import CredentialStore, CredentialObject, CredentialKey
-from pydantic import SecretStr
-
-store = CredentialStore.with_encrypted_storage()
-
-cred = CredentialObject(
-    id="hubspot",
-    name="HubSpot Access Token",
-    keys={
-        "access_token": CredentialKey(
-            name="access_token",
-            value=SecretStr(user_provided_token),
-        )
-    },
-)
-store.save_credential(cred)
-```
-
-**4.2e. Export to Current Session**
-
-```bash
-export HUBSPOT_ACCESS_TOKEN="the-value"
-```
-
-#### Option 3: Local Credential Setup (Advanced)
-
-For programmatic/CI/CD setups.
-
-**4.3a. Show Documentation**
-
-```
-For advanced credential management, you can use the CredentialStore API directly:
-
-  from core.framework.credentials import CredentialStore, CredentialObject, CredentialKey
-  from pydantic import SecretStr
-
-  store = CredentialStore.with_encrypted_storage()
-
-  cred = CredentialObject(
-      id="hubspot",
-      name="HubSpot Access Token",
-      keys={"access_token": CredentialKey(name="access_token", value=SecretStr("..."))}
-  )
-  store.save_credential(cred)
-
-For CI/CD environments:
-  - Set HIVE_CREDENTIAL_KEY for encryption
-  - Pre-populate ~/.hive/credentials programmatically
-  - Or use environment variables directly (HUBSPOT_ACCESS_TOKEN)
-
-Documentation: See core/framework/credentials/README.md
-```
-
-### Step 5: Record Configuration Method
-
-Track which auth method was used for each credential in `~/.hive/configuration.json`:
-
-```python
-import json
-from pathlib import Path
-from datetime import datetime
-
-config_path = Path.home() / ".hive" / "configuration.json"
-config = json.loads(config_path.read_text()) if config_path.exists() else {}
-
-if "credential_methods" not in config:
-    config["credential_methods"] = {}
-
-config["credential_methods"]["hubspot"] = {
-    "method": "aden",  # or "direct" or "custom"
-    "configured_at": datetime.now().isoformat(),
-}
-
-config_path.write_text(json.dumps(config, indent=2))
-```
-
-### Step 6: Verify All Credentials
-
-Use the `verify_credentials` MCP tool to confirm everything is properly configured:
-
-```
-verify_credentials(agent_path="exports/{agent_name}")
-```
-
-The tool returns:
-
-```json
-{
-  "agent": "exports/{agent_name}",
-  "ready": true,
-  "missing_credentials": [],
-  "warnings": [],
-  "errors": []
-}
-```
-
-If `ready` is true, report success. If `missing_credentials` is non-empty, identify what failed and loop back to Step 3 for the remaining credentials.
-
-## Health Check Reference
-
-Health checks validate credentials by making lightweight API calls:

-| --------------- | --------------------------------------- | --------------------------------- |
-| `anthropic`     | `POST /v1/messages`                     | API key validity                  |
-| `brave_search`  | `GET /res/v1/web/search?q=test&count=1` | API key validity                  |
-| `google_search` | `GET /customsearch/v1?q=test&num=1`     | API key + CSE ID validity         |
-| `github`        | `GET /user`                             | Token validity, user identity     |
-| `hubspot`       | `GET /crm/v3/objects/contacts?limit=1`  | Bearer token validity, CRM scopes |
-| `resend`        | `GET /domains`                          | API key validity                  |
-
-```python
-from aden_tools.credentials import check_credential_health, HealthCheckResult
-
-result: HealthCheckResult = check_credential_health("hubspot", token_value)
-# result.valid: bool
-# result.message: str
-# result.details: dict (status_code, rate_limited, etc.)
-```
-
-## Encryption Key (HIVE_CREDENTIAL_KEY)
-
-The local encrypted store requires `HIVE_CREDENTIAL_KEY` to encrypt/decrypt credentials.
-
- If the user doesn't have one, `EncryptedFileStorage` will auto-generate one and log it
- The user MUST persist this key (e.g., in `~/.bashrc`/`~/.zshrc` or a secrets manager)
- Without this key, stored credentials cannot be decrypted
-
-**Shell config rule:** Only TWO keys belong in shell config (`~/.zshrc`/`~/.bashrc`):
- `HIVE_CREDENTIAL_KEY` — encryption key for the credential store
- `ADEN_API_KEY` — Aden platform auth key (needed before the store can sync)
-
-All other API keys (Brave, Google, HubSpot, etc.) must go in the encrypted store only. **Never offer to add them to shell config.**
-
-If `HIVE_CREDENTIAL_KEY` is not set:
-
-1. Let the store generate one
-2. Tell the user to save it: `export HIVE_CREDENTIAL_KEY="{generated_key}"`
-3. Recommend adding it to `~/.bashrc` or their shell profile
-
-## Security Rules
-
- **NEVER** log, print, or echo credential values in tool output
- **NEVER** store credentials in plaintext files, git-tracked files, or agent configs
- **NEVER** hardcode credentials in source code
- **NEVER** offer to save API keys to shell config (`~/.zshrc`/`~/.bashrc`) — the **only** keys that belong in shell config are `HIVE_CREDENTIAL_KEY` and `ADEN_API_KEY`. All other credentials (Brave, Google, HubSpot, GitHub, Resend, etc.) go in the encrypted store only.
- **ALWAYS** use `SecretStr` from Pydantic when handling credential values in Python
- **ALWAYS** use the local encrypted store (`~/.hive/credentials`) for persistence
- **ALWAYS** run health checks before storing credentials (when possible)
- **ALWAYS** verify credentials were stored by re-running validation, not by reading them back
- When modifying `~/.bashrc` or `~/.zshrc`, confirm with the user first
-
-## Credential Sources Reference
-
-All credential specs are defined in `tools/src/aden_tools/credentials/`:
-
-| File              | Category      | Credentials                                   | Aden Supported |
-| ----------------- | ------------- | --------------------------------------------- | -------------- |
-| `llm.py`          | LLM Providers | `anthropic`                                   | No             |
-| `search.py`       | Search Tools  | `brave_search`, `google_search`, `google_cse` | No             |
-| `email.py`        | Email         | `resend`                                      | No             |
-| `integrations.py` | Integrations  | `github`, `hubspot`                           | No / Yes       |
-
-**Note:** Additional LLM providers (Cerebras, Groq, OpenAI) are handled by LiteLLM via environment
-variables (`CEREBRAS_API_KEY`, `GROQ_API_KEY`, `OPENAI_API_KEY`) but are not yet in CREDENTIAL_SPECS.
-Add them to `llm.py` as needed.
-
-To check what's registered:
-
-```python
-from aden_tools.credentials import CREDENTIAL_SPECS
-for name, spec in CREDENTIAL_SPECS.items():
-    print(f"{name}: aden={spec.aden_supported}, direct={spec.direct_api_key_supported}")
-```
-
-## Migration: CredentialManager → CredentialStore
-
-**CredentialManager is deprecated.** Use CredentialStore instead.
-
-| Old (Deprecated)                          | New (Recommended)                                                    |
-| ----------------------------------------- | -------------------------------------------------------------------- |
-| `CredentialManager()`                     | `CredentialStore.with_encrypted_storage()`                           |
-| `creds.get("hubspot")`                    | `store.get("hubspot")` or `store.get_key("hubspot", "access_token")` |
-| `creds.validate_for_tools(tools)`         | Use `store.is_available(cred_id)` per credential                     |
-| `creds.get_auth_options("hubspot")`       | Check `CREDENTIAL_SPECS["hubspot"].aden_supported`                   |
-| `creds.get_setup_instructions("hubspot")` | Access `CREDENTIAL_SPECS["hubspot"]` directly                        |
-
-**Why migrate?**
-
- **CredentialStore** supports encrypted storage, multi-key credentials, template resolution, and automatic token refresh
- **CredentialManager** only reads from environment variables and .env files (no encryption, no refresh)
- **CredentialStoreAdapter** exists for backward compatibility during migration
-
-```python
-# Old way (deprecated)
-from aden_tools.credentials import CredentialManager
-creds = CredentialManager()
-token = creds.get("hubspot")
-
-# New way (recommended)
-from core.framework.credentials import CredentialStore
-store = CredentialStore.with_encrypted_storage()
-token = store.get("hubspot")
-
-# With Aden sync (recommended for OAuth integrations)
-store = CredentialStore.with_aden_sync()
-token = store.get_key("hubspot", "access_token")
-```

-# Building Agents - Patterns & Best Practices
-
-Design patterns, examples, and best practices for building robust goal-driven agents.
-
-**Prerequisites:** Complete agent structure using `hive-create`.
-
-## Practical Example: Hybrid Workflow
-
-How to build a node using both direct file writes and optional MCP validation:
-
-```python
-# 1. WRITE TO FILE FIRST (Primary - makes it visible)
-node_code = '''
-search_node = NodeSpec(
-    id="search-web",
-    node_type="event_loop",
-    input_keys=["query"],
-    output_keys=["search_results"],
-    system_prompt="Search the web for: {query}. Use web_search, then call set_output to store results.",
-    tools=["web_search"],
-)
-'''
-
-Edit(
-    file_path="exports/research_agent/nodes/__init__.py",
-    old_string="# Nodes will be added here",
-    new_string=node_code
-)
-
-# 2. OPTIONALLY VALIDATE WITH MCP (Secondary - bookkeeping)
-validation = mcp__agent-builder__test_node(
-    node_id="search-web",
-    test_input='{"query": "python tutorials"}',
-    mock_llm_response='{"search_results": [...mock results...]}'
-)
-```
-
-**User experience:**
-
- Immediately sees node in their editor (from step 1)
- Gets validation feedback (from step 2)
- Can edit the file directly if needed
-
-## Multi-Turn Interaction Patterns
-
-For agents needing multi-turn conversations with users, use `client_facing=True` on event_loop nodes.
-
-### Client-Facing Nodes
-
-A client-facing node streams LLM output to the user and blocks for user input between conversational turns. This replaces the old pause/resume pattern.
-
-```python
-# Client-facing node with STEP 1/STEP 2 prompt pattern
-intake_node = NodeSpec(
-    id="intake",
-    name="Intake",
-    description="Gather requirements from the user",
-    node_type="event_loop",
-    client_facing=True,
-    input_keys=["topic"],
-    output_keys=["research_brief"],
-    system_prompt="""\
-You are an intake specialist.
-
-**STEP 1 — Read and respond (text only, NO tool calls):**
-1. Read the topic provided
-2. If it's vague, ask 1-2 clarifying questions
-3. If it's clear, confirm your understanding
-
-**STEP 2 — After the user confirms, call set_output:**
- set_output("research_brief", "Clear description of what to research")
-""",
-)
-
-# Internal node runs without user interaction
-research_node = NodeSpec(
-    id="research",
-    name="Research",
-    description="Search and analyze sources",
-    node_type="event_loop",
-    input_keys=["research_brief"],
-    output_keys=["findings", "sources"],
-    system_prompt="Research the topic using web_search and web_scrape...",
-    tools=["web_search", "web_scrape", "load_data", "save_data"],
-)
-```
-
-**How it works:**
-
- Client-facing nodes stream LLM text to the user and block for input after each response
- User input is injected via `node.inject_event(text)`
- When the LLM calls `set_output` to produce structured outputs, the judge evaluates and ACCEPTs
- Internal nodes (non-client-facing) run their entire loop without blocking
- `set_output` is a synthetic tool — a turn with only `set_output` calls (no real tools) triggers user input blocking
-
-**STEP 1/STEP 2 pattern:** Always structure client-facing prompts with explicit phases. STEP 1 is text-only conversation. STEP 2 calls `set_output` after user confirmation. This prevents the LLM from calling `set_output` prematurely before the user responds.
-
-### When to Use client_facing
-
-| Scenario                            | client_facing | Why                    |
-| ----------------------------------- | :-----------: | ---------------------- |
-| Gathering user requirements         |      Yes      | Need user input        |
-| Human review/approval checkpoint    |      Yes      | Need human decision    |
-| Data processing (scanning, scoring) |      No       | Runs autonomously      |
-| Report generation                   |      No       | No user input needed   |
-| Final confirmation before action    |      Yes      | Need explicit approval |
-
-> **Legacy Note:** The `pause_nodes` / `entry_points` pattern still works for backward compatibility but `client_facing=True` is preferred for new agents.
-
-## Edge-Based Routing and Feedback Loops
-
-### Conditional Edge Routing
-
-Multiple conditional edges from the same source replace the old `router` node type. Each edge checks a condition on the node's output.
-
-```python
-# Node with mutually exclusive outputs
-review_node = NodeSpec(
-    id="review",
-    name="Review",
-    node_type="event_loop",
-    client_facing=True,
-    output_keys=["approved_contacts", "redo_extraction"],
-    nullable_output_keys=["approved_contacts", "redo_extraction"],
-    max_node_visits=3,
-    system_prompt="Present the contact list to the operator. If they approve, call set_output('approved_contacts', ...). If they want changes, call set_output('redo_extraction', 'true').",
-)
-
-# Forward edge (positive priority, evaluated first)
-EdgeSpec(
-    id="review-to-campaign",
-    source="review",
-    target="campaign-builder",
-    condition=EdgeCondition.CONDITIONAL,
-    condition_expr="output.get('approved_contacts') is not None",
-    priority=1,
-)
-
-# Feedback edge (negative priority, evaluated after forward edges)
-EdgeSpec(
-    id="review-feedback",
-    source="review",
-    target="extractor",
-    condition=EdgeCondition.CONDITIONAL,
-    condition_expr="output.get('redo_extraction') is not None",
-    priority=-1,
-)
-```
-
-**Key concepts:**
-
- `nullable_output_keys`: Lists output keys that may remain unset. The node sets exactly one of the mutually exclusive keys per execution.
- `max_node_visits`: Must be >1 on the feedback target (extractor) so it can re-execute. Default is 1.
- `priority`: Positive = forward edge (evaluated first). Negative = feedback edge. The executor tries forward edges first; if none match, falls back to feedback edges.
-
-### Routing Decision Table
-
-| Pattern                | Old Approach            | New Approach                                  |
-| ---------------------- | ----------------------- | --------------------------------------------- |
-| Conditional branching  | `router` node           | Conditional edges with `condition_expr`       |
-| Binary approve/reject  | `pause_nodes` + resume  | `client_facing=True` + `nullable_output_keys` |
-| Loop-back on rejection | Manual entry_points     | Feedback edge with `priority=-1`              |
-| Multi-way routing      | Router with routes dict | Multiple conditional edges with priorities    |
-
-## Judge Patterns
-
-**Core Principle: The judge is the SOLE mechanism for acceptance decisions.** Never add ad-hoc framework gating to compensate for LLM behavior. If the LLM calls `set_output` prematurely, fix the system prompt or use a custom judge. Anti-patterns to avoid:
-
- Output rollback logic
- `_user_has_responded` flags
- Premature set_output rejection
- Interaction protocol injection into system prompts
-
-Judges control when an event_loop node's loop exits. Choose based on validation needs.
-
-### Implicit Judge (Default)
-
-When no judge is configured, the implicit judge ACCEPTs when:
-
- The LLM finishes its response with no tool calls
- All required output keys have been set via `set_output`
-
-Best for simple nodes where "all outputs set" is sufficient validation.
-
-### SchemaJudge
-
-Validates outputs against a Pydantic model. Use when you need structural validation.
-
-```python
-from pydantic import BaseModel
-
-class ScannerOutput(BaseModel):
-    github_users: list[dict]  # Must be a list of user objects
-
-class SchemaJudge:
-    def __init__(self, output_model: type[BaseModel]):
-        self._model = output_model
-
-    async def evaluate(self, context: dict) -> JudgeVerdict:
-        missing = context.get("missing_keys", [])
-        if missing:
-            return JudgeVerdict(
-                action="RETRY",
-                feedback=f"Missing output keys: {missing}. Use set_output to provide them.",
-            )
-        try:
-            self._model.model_validate(context["output_accumulator"])
-            return JudgeVerdict(action="ACCEPT")
-        except ValidationError as e:
-            return JudgeVerdict(action="RETRY", feedback=str(e))
-```
-
-### When to Use Which Judge
-
-| Judge           | Use When                              | Example                |
-| --------------- | ------------------------------------- | ---------------------- |
-| Implicit (None) | Output keys are sufficient validation | Simple data extraction |
-| SchemaJudge     | Need structural validation of outputs | API response parsing   |
-| Custom          | Domain-specific validation logic      | Score must be 0.0-1.0  |
-
-## Fan-Out / Fan-In (Parallel Execution)
-
-Multiple ON_SUCCESS edges from the same source trigger parallel execution. All branches run concurrently via `asyncio.gather()`.
-
-```python
-# Scanner fans out to Profiler and Scorer in parallel
-EdgeSpec(id="scanner-to-profiler", source="scanner", target="profiler",
-         condition=EdgeCondition.ON_SUCCESS)
-EdgeSpec(id="scanner-to-scorer", source="scanner", target="scorer",
-         condition=EdgeCondition.ON_SUCCESS)
-
-# Both fan in to Extractor
-EdgeSpec(id="profiler-to-extractor", source="profiler", target="extractor",
-         condition=EdgeCondition.ON_SUCCESS)
-EdgeSpec(id="scorer-to-extractor", source="scorer", target="extractor",
-         condition=EdgeCondition.ON_SUCCESS)
-```
-
-**Requirements:**
-
- Parallel event_loop nodes must have **disjoint output_keys** (no key written by both)
- Only one parallel branch may contain a `client_facing` node
- Fan-in node receives outputs from all completed branches in shared memory
-
-## Context Management Patterns
-
-### Tiered Compaction
-
-EventLoopNode automatically manages context window usage with tiered compaction:
-
-1. **Pruning** — Old tool results replaced with compact placeholders (zero-cost, no LLM call)
-2. **Normal compaction** — LLM summarizes older messages
-3. **Aggressive compaction** — Keeps only recent messages + summary
-4. **Emergency** — Hard reset with tool history preservation
-
-### Spillover Pattern
-
-The framework automatically truncates large tool results and saves full content to a spillover directory. The LLM receives a truncation message with instructions to use `load_data` to read the full result.
-
-For explicit data management, use the data tools (real MCP tools, not synthetic):
-
-```python
-# save_data, load_data, list_data_files, serve_file_to_user are real MCP tools
-# data_dir is auto-injected by the framework — the LLM never sees it
-
-# Saving large results
-save_data(filename="sources.json", data=large_json_string)
-
-# Reading with pagination (line-based offset/limit)
-load_data(filename="sources.json", offset=0, limit=50)
-
-# Listing available files
-list_data_files()
-
-# Serving a file to the user as a clickable link
-serve_file_to_user(filename="report.html", label="Research Report")
-```
-
-Add data tools to nodes that handle large tool results:
-
-```python
-research_node = NodeSpec(
-    ...
-    tools=["web_search", "web_scrape", "load_data", "save_data", "list_data_files"],
-)
-```
-
-`data_dir` is a framework context parameter — auto-injected at call time. `GraphExecutor.execute()` sets it per-execution via `ToolRegistry.set_execution_context(data_dir=...)` (using `contextvars` for concurrency safety), ensuring it matches the session-scoped spillover directory.
-
-## Anti-Patterns
-
-### What NOT to Do
-
- **Don't rely on `export_graph`** — Write files immediately, not at end
- **Don't hide code in session** — Write to files as components are approved
- **Don't wait to write files** — Agent visible from first step
- **Don't batch everything** — Write incrementally, one component at a time
- **Don't create too many thin nodes** — Prefer fewer, richer nodes (see below)
- **Don't add framework gating for LLM behavior** — Fix prompts or use judges instead
-
-### Fewer, Richer Nodes
-
-A common mistake is splitting work into too many small single-purpose nodes. Each node boundary requires serializing outputs, losing in-context information, and adding edge complexity.
-
-| Bad (8 thin nodes)  | Good (4 rich nodes)                 |
-| ------------------- | ----------------------------------- |
-| parse-query         | intake (client-facing)              |
-| search-sources      | research (search + fetch + analyze) |
-| fetch-content       | review (client-facing)              |
-| evaluate-sources    | report (write + deliver)            |
-| synthesize-findings |                                     |
-| write-report        |                                     |
-| quality-check       |                                     |
-| save-report         |                                     |
-
-**Why fewer nodes are better:**
-
- The LLM retains full context of its work within a single node
- A research node that searches, fetches, and analyzes keeps all source material in its conversation history
- Fewer edges means simpler graph and fewer failure points
- Data tools (`save_data`/`load_data`) handle context window limits within a single node
-
-### MCP Tools - Correct Usage
-
-**MCP tools OK for:**
-
- `test_node` — Validate node configuration with mock inputs
- `validate_graph` — Check graph structure
- `configure_loop` — Set event loop parameters
- `create_session` — Track session state for bookkeeping
-
-**Just don't:** Use MCP as the primary construction method or rely on export_graph
-
-## Error Handling Patterns
-
-### Graceful Failure with Fallback
-
-```python
-edges = [
-    # Success path
-    EdgeSpec(id="api-success", source="api-call", target="process-results",
-             condition=EdgeCondition.ON_SUCCESS),
-    # Fallback on failure
-    EdgeSpec(id="api-to-fallback", source="api-call", target="fallback-cache",
-             condition=EdgeCondition.ON_FAILURE, priority=1),
-    # Report if fallback also fails
-    EdgeSpec(id="fallback-to-error", source="fallback-cache", target="report-error",
-             condition=EdgeCondition.ON_FAILURE, priority=1),
-]
-```
-
-## Handoff to Testing
-
-When agent is complete, transition to testing phase:
-
-### Pre-Testing Checklist
-
- [ ] Agent structure validates: `uv run python -m agent_name validate`
- [ ] All nodes defined in nodes/**init**.py
- [ ] All edges connect valid nodes with correct priorities
- [ ] Feedback edge targets have `max_node_visits > 1`
- [ ] Client-facing nodes have meaningful system prompts
- [ ] Agent can be imported: `from exports.agent_name import default_agent`

-# Agent Testing
-
-Test agents iteratively: execute, analyze failures, fix, resume from checkpoint, repeat.
-
-## When to Use
-
- Testing a newly built agent against its goal
- Debugging a failing agent iteratively
- Verifying fixes without re-running expensive early nodes
- Running final regression tests before deployment
-
-## Prerequisites
-
-1. Agent package at `exports/{agent_name}/` (built with `/hive-create`)
-2. Credentials configured (`/hive-credentials`)
-3. `ANTHROPIC_API_KEY` set (or appropriate LLM provider key)
-
-**Path distinction** (critical — don't confuse these):
- `exports/{agent_name}/` — agent source code (edit here)
- `~/.hive/agents/{agent_name}/` — runtime data: sessions, checkpoints, logs (read here)
-
---
-
-## The Iterative Test Loop
-
-This is the core workflow. Don't re-run the entire agent when a late node fails — analyze, fix, and resume from the last clean checkpoint.

-
-### Phase 1: Generate Test Scenarios
-
-Create synthetic tests from the agent's goal, constraints, and success criteria.
-
-#### Step 1a: Read the goal
-
-```python
-# Read goal from agent.py
-Read(file_path="exports/{agent_name}/agent.py")
-# Extract the Goal definition and convert to JSON string
-```
-
-#### Step 1b: Get test guidelines
-
-```python
-# Get constraint test guidelines
-generate_constraint_tests(
-    goal_id="your-goal-id",
-    goal_json='{"id": "...", "constraints": [...]}',
-    agent_path="exports/{agent_name}"
-)
-
-# Get success criteria test guidelines
-generate_success_tests(
-    goal_id="your-goal-id",
-    goal_json='{"id": "...", "success_criteria": [...]}',
-    node_names="intake,research,review,report",
-    tool_names="web_search,web_scrape",
-    agent_path="exports/{agent_name}"
-)
-```
-
-These return `file_header`, `test_template`, `constraints_formatted`/`success_criteria_formatted`, and `test_guidelines`. They do NOT generate test code — you write the tests.
-
-#### Step 1c: Write tests
-
-```python
-Write(
-    file_path=result["output_file"],
-    content=result["file_header"] + "\n\n" + your_test_code
-)
-```
-
-#### Test writing rules
-
- Every test MUST be `async` with `@pytest.mark.asyncio`
- Every test MUST accept `runner, auto_responder, mock_mode` fixtures
- Use `await auto_responder.start()` before running, `await auto_responder.stop()` in `finally`
- Use `await runner.run(input_dict)` — this goes through AgentRunner → AgentRuntime → ExecutionStream
- Access output via `result.output.get("key")` — NEVER `result.output["key"]`
- `result.success=True` means no exception, NOT goal achieved — always check output
- Write 8-15 tests total, not 30+
- Each real test costs ~3 seconds + LLM tokens
- NEVER use `default_agent.run()` — it bypasses the runtime (no sessions, no logs, client-facing nodes hang)
-
-#### Step 1d: Check existing tests
-
-Before generating, check if tests already exist:
-
-```python
-list_tests(
-    goal_id="your-goal-id",
-    agent_path="exports/{agent_name}"
-)
-```
-
---
-
-### Phase 2: Execute
-
-Two execution paths, use the right one for your situation.
-
-#### Iterative debugging (for complex agents)
-
-Run the agent via CLI. This creates sessions with checkpoints at `~/.hive/agents/{agent_name}/sessions/`:
-
-```bash
-uv run hive run exports/{agent_name} --input '{"query": "test topic"}'
-```
-
-Sessions and checkpoints are saved automatically.
-
-**Client-facing nodes**: Agents with `client_facing=True` nodes (interactive conversation) work in headless mode when run from a real terminal — the agent streams output to stdout and reads user input from stdin via a `>>> ` prompt. In non-interactive shells (like Claude Code's Bash tool), client-facing nodes will hang because there is no stdin. For testing interactive agents from Claude Code, use `run_tests` with mock mode or have the user run the agent manually in their terminal.
-
-#### Automated regression (for CI or final verification)
-
-Use the `run_tests` MCP tool to run all pytest tests:
-
-```python
-run_tests(
-    goal_id="your-goal-id",
-    agent_path="exports/{agent_name}"
-)
-```
-
-Returns structured results:
-```json
-{
-  "overall_passed": false,
-  "summary": {"total": 12, "passed": 10, "failed": 2, "pass_rate": "83.3%"},
-  "test_results": [{"test_name": "test_success_source_diversity", "status": "failed"}],
-  "failures": [{"test_name": "test_success_source_diversity", "details": "..."}]
-}
-```
-
-**Options:**
-```python
-# Run only constraint tests
-run_tests(goal_id, agent_path, test_types='["constraint"]')
-
-# Stop on first failure
-run_tests(goal_id, agent_path, fail_fast=True)
-
-# Parallel execution
-run_tests(goal_id, agent_path, parallel=4)
-```
-
-**Note:** `run_tests` uses `AgentRunner` with `tmp_path` storage, so sessions are isolated per test run. For checkpoint-based recovery with persistent sessions, use CLI execution. Use `run_tests` for quick regression checks and final verification.
-
---
-
-### Phase 3: Analyze Failures
-
-When a test fails, drill down systematically. Don't guess — use the tools.
-
-#### Step 3a: Get error category
-
-```python
-debug_test(
-    goal_id="your-goal-id",
-    test_name="test_success_source_diversity",
-    agent_path="exports/{agent_name}"
-)
-```
-
-Returns error category (`IMPLEMENTATION_ERROR`, `ASSERTION_FAILURE`, `TIMEOUT`, `IMPORT_ERROR`, `API_ERROR`) plus full traceback and suggestions.
-
-#### Step 3b: Find the failed session
-
-```python
-list_agent_sessions(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    status="failed",
-    limit=5
-)
-```
-
-Returns session list with IDs, timestamps, current_node (where it failed), execution_quality.
-
-#### Step 3c: Inspect session state
-
-```python
-get_agent_session_state(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    session_id="session_20260209_143022_abc12345"
-)
-```
-
-Returns execution path, which node was current, step count, timestamps — but excludes memory values (to avoid context bloat). Shows `memory_keys` and `memory_size` instead.
-
-#### Step 3d: Examine runtime logs (L2/L3)
-
-```python
-# L2: Per-node success/failure, retry counts
-query_runtime_log_details(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    run_id="session_20260209_143022_abc12345",
-    needs_attention_only=True
-)
-
-# L3: Exact LLM responses, tool call inputs/outputs
-query_runtime_log_raw(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    run_id="session_20260209_143022_abc12345",
-    node_id="research"
-)
-```
-
-#### Step 3e: Inspect memory data
-
-```python
-# See what data a node actually produced
-get_agent_session_memory(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    session_id="session_20260209_143022_abc12345",
-    key="research_results"
-)
-```
-
-#### Step 3f: Find recovery points
-
-```python
-list_agent_checkpoints(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    session_id="session_20260209_143022_abc12345",
-    is_clean="true"
-)
-```
-
-Returns checkpoint summaries with IDs, types (`node_start`, `node_complete`), which node, and `is_clean` flag. Clean checkpoints are safe resume points.
-
-#### Step 3g: Compare checkpoints (optional)
-
-To understand what changed between two points in execution:
-
-```python
-compare_agent_checkpoints(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    session_id="session_20260209_143022_abc12345",
-    checkpoint_id_before="cp_node_complete_research_143030",
-    checkpoint_id_after="cp_node_complete_review_143115"
-)
-```
-
-Returns memory diff (added/removed/changed keys) and execution path diff.
-
---
-
-### Phase 4: Fix Based on Root Cause
-
-Use the analysis from Phase 3 to determine what to fix and where.
-
-| Root Cause | What to Fix | Where to Edit |
-|------------|------------|---------------|
-| **Prompt issue** — LLM produces wrong output format, misses instructions | Node `system_prompt` | `exports/{agent}/nodes/__init__.py` |
-| **Code bug** — TypeError, KeyError, logic error in Python | Agent code | `exports/{agent}/agent.py`, `nodes/__init__.py` |
-| **Graph issue** — wrong routing, missing edge, bad condition_expr | Edges, node config | `exports/{agent}/agent.py` |
-| **Tool issue** — MCP tool fails, wrong config, missing credential | Tool config | `exports/{agent}/mcp_servers.json`, `/hive-credentials` |
-| **Goal issue** — success criteria too strict/vague, wrong constraints | Goal definition | `exports/{agent}/agent.py` (goal section) |
-| **Test issue** — test expectations don't match actual agent behavior | Test code | `exports/{agent}/tests/test_*.py` |
-
-#### Fix strategies by error category
-
-**IMPLEMENTATION_ERROR** (TypeError, AttributeError, KeyError):
-```python
-# Read the failing code
-Read(file_path="exports/{agent_name}/nodes/__init__.py")
-
-# Fix the bug
-Edit(
-    file_path="exports/{agent_name}/nodes/__init__.py",
-    old_string="results.get('videos')",
-    new_string="(results or {}).get('videos', [])"
-)
-```
-
-**ASSERTION_FAILURE** (test assertions fail but agent ran successfully):
- Check if the agent's output is actually wrong → fix the prompt
- Check if the test's expectations are unrealistic → fix the test
- Use `get_agent_session_memory` to see what the agent actually produced
-
-**TIMEOUT / STALL** (agent runs too long):
- Check `node_visit_counts` for feedback loops hitting max_node_visits
- Check L3 logs for tool calls that hang
- Reduce `max_iterations` in loop_config or fix the prompt to converge faster
-
-**API_ERROR** (connection, rate limit, auth):
- Verify credentials with `/hive-credentials`
- Check MCP server configuration
-
---
-
-### Phase 5: Recover & Resume
-
-After fixing the agent, decide whether to resume or re-run.
-
-#### When to resume from checkpoint
-
-Resume when ALL of these are true:
- The fix is to a node that comes AFTER existing clean checkpoints
- Clean checkpoints exist (from a CLI execution with checkpointing)
- The early nodes are expensive (web scraping, API calls, long LLM chains)
-
-```bash
-# Resume from the last clean checkpoint before the failing node
-uv run hive run exports/{agent_name} \
-  --resume-session session_20260209_143022_abc12345 \
-  --checkpoint cp_node_complete_research_143030
-```
-
-This skips all nodes before the checkpoint and only re-runs the fixed node onward.
-
-#### When to re-run from scratch
-
-Re-run when ANY of these are true:
- The fix is to the entry node or an early node
- No checkpoints exist (e.g., agent was run via `run_tests`)
- The agent is fast (2-3 nodes, completes in seconds)
- You changed the graph structure (added/removed nodes/edges)
-
-```bash
-uv run hive run exports/{agent_name} --input '{"query": "test topic"}'
-```
-
-#### Inspecting a checkpoint before resuming
-
-```python
-get_agent_checkpoint(
-    agent_work_dir="~/.hive/agents/{agent_name}",
-    session_id="session_20260209_143022_abc12345",
-    checkpoint_id="cp_node_complete_research_143030"
-)
-```
-
-Returns the full checkpoint: shared_memory snapshot, execution_path, current_node, next_node, is_clean.
-
-#### Loop back to Phase 2
-
-After resuming or re-running, check if the fix worked. If not, go back to Phase 3.
-
---
-
-### Phase 6: Final Verification
-
-Once the iterative fix loop converges (the agent produces correct output), run the full automated test suite:
-
-```python
-run_tests(
-    goal_id="your-goal-id",
-    agent_path="exports/{agent_name}"
-)
-```
-
-All tests should pass. If not, repeat the loop for remaining failures.
-
---
-
-## Credential Requirements
-
-**CRITICAL: Testing requires ALL credentials the agent depends on.** This includes both the LLM API key AND any tool-specific credentials (HubSpot, Brave Search, etc.).
-
-### Prerequisites
-
-Before running agent tests, you MUST collect ALL required credentials from the user.
-
-**Step 1: LLM API Key (always required)**
-```bash
-export ANTHROPIC_API_KEY="your-key-here"
-```
-
-**Step 2: Tool-specific credentials (depends on agent's tools)**
-
-Inspect the agent's `mcp_servers.json` and tool configuration to determine which tools the agent uses, then check for all required credentials:
-
-```python
-from aden_tools.credentials import CredentialManager, CREDENTIAL_SPECS
-
-creds = CredentialManager()
-
-# Determine which tools the agent uses (from agent.json or mcp_servers.json)
-agent_tools = [...]  # e.g., ["hubspot_search_contacts", "web_search", ...]
-
-# Find all missing credentials for those tools
-missing = creds.get_missing_for_tools(agent_tools)
-```
-
-Common tool credentials:
-| Tool | Env Var | Help URL |
-|------|---------|----------|
-| HubSpot CRM | `HUBSPOT_ACCESS_TOKEN` | https://developers.hubspot.com/docs/api/private-apps |
-| Brave Search | `BRAVE_SEARCH_API_KEY` | https://brave.com/search/api/ |
-| Google Search | `GOOGLE_SEARCH_API_KEY` + `GOOGLE_SEARCH_CX` | https://developers.google.com/custom-search |
-
-**Why ALL credentials are required:**
- Tests need to execute the agent's LLM nodes to validate behavior
- Tools with missing credentials will return error dicts instead of real data
- Mock mode bypasses everything, providing no confidence in real-world performance
-
-### Mock Mode Limitations
-
-Mock mode (`--mock` flag or `MOCK_MODE=1`) is **ONLY for structure validation**:
-
- Validates graph structure (nodes, edges, connections)
- Validates that `AgentRunner.load()` succeeds and the agent is importable
- Does NOT execute event_loop agents — MockLLMProvider never calls `set_output`, so event_loop nodes loop forever
- Does NOT test LLM reasoning, content quality, or constraint validation
- Does NOT test real API integrations or tool use
-
-**Bottom line:** If you're testing whether an agent achieves its goal, you MUST use real credentials.
-
-### Enforcing Credentials in Tests
-
-When writing tests, **ALWAYS include credential checks**:
-
-```python
-import os
-import pytest
-from aden_tools.credentials import CredentialManager
-
-pytestmark = pytest.mark.skipif(
-    not CredentialManager().is_available("anthropic") and not os.environ.get("MOCK_MODE"),
-    reason="API key required for real testing. Set ANTHROPIC_API_KEY or use MOCK_MODE=1."
-)
-
-
-@pytest.fixture(scope="session", autouse=True)
-def check_credentials():
-    """Ensure ALL required credentials are set for real testing."""
-    creds = CredentialManager()
-    mock_mode = os.environ.get("MOCK_MODE")
-
-    if not creds.is_available("anthropic"):
-        if mock_mode:
-            print("\nRunning in MOCK MODE - structure validation only")
-        else:
-            pytest.fail(
-                "\nANTHROPIC_API_KEY not set!\n"
-                "Set API key: export ANTHROPIC_API_KEY='your-key-here'\n"
-                "Or run structure validation: MOCK_MODE=1 pytest exports/{agent}/tests/"
-            )
-
-    if not mock_mode:
-        agent_tools = []  # Update per agent
-        missing = creds.get_missing_for_tools(agent_tools)
-        if missing:
-            lines = ["\nMissing tool credentials!"]
-            for name in missing:
-                spec = creds.specs.get(name)
-                if spec:
-                    lines.append(f"  {spec.env_var} - {spec.description}")
-            pytest.fail("\n".join(lines))
-```
-
-### User Communication
-
-When the user asks to test an agent, **ALWAYS check for ALL credentials first**:
-
-1. **Identify the agent's tools** from `mcp_servers.json`
-2. **Check ALL required credentials** using `CredentialManager`
-3. **Ask the user to provide any missing credentials** before proceeding
-4. Collect ALL missing credentials in a single prompt — not one at a time
-
---
-
-## Safe Test Patterns
-
-### OutputCleaner
-
-The framework automatically validates and cleans node outputs using a fast LLM at edge traversal time. Tests should still use safe patterns because OutputCleaner may not catch all issues.
-
-### Safe Access (REQUIRED)
-
-```python
-# UNSAFE - will crash on missing keys
-approval = result.output["approval_decision"]
-category = result.output["analysis"]["category"]
-
-# SAFE - use .get() with defaults
-output = result.output or {}
-approval = output.get("approval_decision", "UNKNOWN")
-
-# SAFE - type check before operations
-analysis = output.get("analysis", {})
-if isinstance(analysis, dict):
-    category = analysis.get("category", "unknown")

-### ExecutionResult Fields
-
-**`result.success=True` means NO exception, NOT goal achieved**
-
-```python
-# WRONG
-assert result.success
-
-# RIGHT
-assert result.success, f"Agent failed: {result.error}"
-output = result.output or {}
-approval = output.get("approval_decision")
-assert approval == "APPROVED", f"Expected APPROVED, got {approval}"
-```
-
-All fields:
- `success: bool` — Completed without exception (NOT goal achieved!)
- `output: dict` — Complete memory snapshot (may contain raw strings)
- `error: str | None` — Error message if failed
- `steps_executed: int` — Number of nodes executed
- `total_tokens: int` — Cumulative token usage
- `total_latency_ms: int` — Total execution time
- `path: list[str]` — Node IDs traversed (may repeat in feedback loops)
- `paused_at: str | None` — Node ID if paused
- `session_state: dict` — State for resuming
- `node_visit_counts: dict[str, int]` — Visit counts per node (feedback loop testing)
- `execution_quality: str` — "clean", "degraded", or "failed"
-
-### Test Count Guidance
-
-**Write 8-15 tests, not 30+**
-
- 2-3 tests per success criterion
- 1 happy path test
- 1 boundary/edge case test
- 1 error handling test (optional)
-
-Each real test costs ~3 seconds + LLM tokens. 12 tests = ~36 seconds, $0.12.
-
---
-
-## Test Patterns
-
-### Happy Path
-```python
-@pytest.mark.asyncio
-async def test_happy_path(runner, auto_responder, mock_mode):
-    """Test normal successful execution."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": "python tutorials"})
-    finally:
-        await auto_responder.stop()
-    assert result.success, f"Agent failed: {result.error}"
-    output = result.output or {}
-    assert output.get("report"), "No report produced"
-```
-
-### Boundary Condition
-```python
-@pytest.mark.asyncio
-async def test_minimum_sources(runner, auto_responder, mock_mode):
-    """Test at minimum source threshold."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": "niche topic"})
-    finally:
-        await auto_responder.stop()
-    assert result.success, f"Agent failed: {result.error}"
-    output = result.output or {}
-    sources = output.get("sources", [])
-    if isinstance(sources, list):
-        assert len(sources) >= 3, f"Expected >= 3 sources, got {len(sources)}"
-```
-
-### Error Handling
-```python
-@pytest.mark.asyncio
-async def test_empty_input(runner, auto_responder, mock_mode):
-    """Test graceful handling of empty input."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": ""})
-    finally:
-        await auto_responder.stop()
-    # Agent should either fail gracefully or produce an error message
-    output = result.output or {}
-    assert not result.success or output.get("error"), "Should handle empty input"
-```
-
-### Feedback Loop
-```python
-@pytest.mark.asyncio
-async def test_feedback_loop_terminates(runner, auto_responder, mock_mode):
-    """Test that feedback loops don't run forever."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": "test"})
-    finally:
-        await auto_responder.stop()
-    visits = result.node_visit_counts or {}
-    for node_id, count in visits.items():
-        assert count <= 5, f"Node {node_id} visited {count} times — possible infinite loop"
-```
-

-
-## MCP Tool Reference
-
-### Phase 1: Test Generation
-
-```python
-# Check existing tests
-list_tests(goal_id, agent_path)
-
-# Get constraint test guidelines (returns templates, NOT generated tests)
-generate_constraint_tests(goal_id, goal_json, agent_path)
-# Returns: output_file, file_header, test_template, constraints_formatted, test_guidelines
-
-# Get success criteria test guidelines
-generate_success_tests(goal_id, goal_json, node_names, tool_names, agent_path)
-# Returns: output_file, file_header, test_template, success_criteria_formatted, test_guidelines
-```
-
-### Phase 2: Execution
-
-```python
-# Automated regression (no checkpoints, fresh runs)
-run_tests(goal_id, agent_path, test_types='["all"]', parallel=-1, fail_fast=False)
-
-# Run only specific test types
-run_tests(goal_id, agent_path, test_types='["constraint"]')
-run_tests(goal_id, agent_path, test_types='["success"]')
-```
-
-```bash
-# Iterative debugging with checkpoints (via CLI)
-uv run hive run exports/{agent_name} --input '{"query": "test"}'
-```
-
-### Phase 3: Analysis
-
-```python
-# Debug a specific failed test
-debug_test(goal_id, test_name, agent_path)
-
-# Find failed sessions
-list_agent_sessions(agent_work_dir, status="failed", limit=5)
-
-# Inspect session state (excludes memory values)
-get_agent_session_state(agent_work_dir, session_id)
-
-# Inspect memory data
-get_agent_session_memory(agent_work_dir, session_id, key="research_results")
-
-# Runtime logs: L1 summaries
-query_runtime_logs(agent_work_dir, status="needs_attention")
-
-# Runtime logs: L2 per-node details
-query_runtime_log_details(agent_work_dir, run_id, needs_attention_only=True)
-
-# Runtime logs: L3 tool/LLM raw data
-query_runtime_log_raw(agent_work_dir, run_id, node_id="research")
-
-# Find clean checkpoints
-list_agent_checkpoints(agent_work_dir, session_id, is_clean="true")
-
-# Compare checkpoints (memory diff)
-compare_agent_checkpoints(agent_work_dir, session_id, cp_before, cp_after)
-```
-
-### Phase 5: Recovery
-
-```python
-# Inspect checkpoint before resuming
-get_agent_checkpoint(agent_work_dir, session_id, checkpoint_id)
-# Empty checkpoint_id = latest checkpoint
-```
-
-```bash
-# Resume from checkpoint via CLI (headless)
-uv run hive run exports/{agent_name} \
-  --resume-session {session_id} --checkpoint {checkpoint_id}
-```
-
---
-
-## Anti-Patterns
-
-| Don't | Do Instead |
-|-------|-----------|
-| Use `default_agent.run()` in tests | Use `runner.run()` with `auto_responder` fixtures (goes through AgentRuntime) |
-| Re-run entire agent when a late node fails | Resume from last clean checkpoint |
-| Treat `result.success` as goal achieved | Check `result.output` for actual criteria |
-| Access `result.output["key"]` directly | Use `result.output.get("key")` |
-| Fix random things hoping tests pass | Analyze L2/L3 logs to find root cause first |
-| Write 30+ tests | Write 8-15 focused tests |
-| Skip credential check | Use `/hive-credentials` before testing |
-| Confuse `exports/` with `~/.hive/agents/` | Code in `exports/`, runtime data in `~/.hive/` |
-| Use `run_tests` for iterative debugging | Use headless CLI with checkpoints for iterative debugging |
-| Use headless CLI for final regression | Use `run_tests` for automated regression |
-| Use `--tui` from Claude Code | Use headless `run` command — TUI hangs in non-interactive shells |
-| Test client-facing nodes from Claude Code | Use mock mode, or have the user run the agent in their terminal |
-| Run tests without reading goal first | Always understand the goal before writing tests |
-| Skip Phase 3 analysis and guess | Use session + log tools to identify root cause |

-## Example Walkthrough: Deep Research Agent
-
-A complete iteration showing the test loop for an agent with nodes: `intake → research → review → report`.
-
-### Phase 1: Generate tests
-
-```python
-# Read the goal
-Read(file_path="exports/deep_research_agent/agent.py")
-
-# Get success criteria test guidelines
-result = generate_success_tests(
-    goal_id="rigorous-interactive-research",
-    goal_json='{"id": "rigorous-interactive-research", "success_criteria": [{"id": "source-diversity", "target": ">=5"}, {"id": "citation-coverage", "target": "100%"}, {"id": "report-completeness", "target": "90%"}]}',
-    node_names="intake,research,review,report",
-    tool_names="web_search,web_scrape",
-    agent_path="exports/deep_research_agent"
-)
-
-# Write tests
-Write(
-    file_path=result["output_file"],
-    content=result["file_header"] + "\n\n" + test_code
-)
-```
-
-### Phase 2: First execution
-
-```python
-run_tests(
-    goal_id="rigorous-interactive-research",
-    agent_path="exports/deep_research_agent",
-    fail_fast=True
-)
-```
-
-Result: `test_success_source_diversity` fails — agent only found 2 sources instead of 5.
-
-### Phase 3: Analyze
-
-```python
-# Debug the failing test
-debug_test(
-    goal_id="rigorous-interactive-research",
-    test_name="test_success_source_diversity",
-    agent_path="exports/deep_research_agent"
-)
-# → ASSERTION_FAILURE: Expected >= 5 sources, got 2
-
-# Find the session
-list_agent_sessions(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    status="completed",
-    limit=1
-)
-# → session_20260209_150000_abc12345
-
-# See what the research node produced
-get_agent_session_memory(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    session_id="session_20260209_150000_abc12345",
-    key="research_results"
-)
-# → Only 2 web_search calls made, each returned 1 source
-
-# Check the LLM's behavior in the research node
-query_runtime_log_raw(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    run_id="session_20260209_150000_abc12345",
-    node_id="research"
-)
-# → LLM called web_search only twice, then called set_output
-```
-
-Root cause: The research node's prompt doesn't tell the LLM to search for at least 5 diverse sources. It stops after the first couple of searches.
-
-### Phase 4: Fix the prompt
-
-```python
-Read(file_path="exports/deep_research_agent/nodes/__init__.py")
-
-Edit(
-    file_path="exports/deep_research_agent/nodes/__init__.py",
-    old_string='system_prompt="Search for information on the user\'s topic."',
-    new_string='system_prompt="Search for information on the user\'s topic. You MUST find at least 5 diverse, authoritative sources. Use multiple different search queries to ensure source diversity. Do not stop searching until you have at least 5 distinct sources."'
-)
-```
-
-### Phase 5: Resume from checkpoint
-
-For this example, the fix is to the `research` node. If we had run via CLI with checkpointing, we could resume from the checkpoint after `intake` to skip re-running intake:
-
-```bash
-# Check if clean checkpoint exists after intake
-list_agent_checkpoints(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    session_id="session_20260209_150000_abc12345",
-    is_clean="true"
-)
-# → cp_node_complete_intake_150005
-
-# Resume from after intake, re-run research with fixed prompt
-uv run hive run exports/deep_research_agent \
-  --resume-session session_20260209_150000_abc12345 \
-  --checkpoint cp_node_complete_intake_150005
-```
-
-Or for this simple case (intake is fast), just re-run:
-
-```bash
-uv run hive run exports/deep_research_agent --input '{"topic": "test"}'
-```
-
-### Phase 6: Final verification
-
-```python
-run_tests(
-    goal_id="rigorous-interactive-research",
-    agent_path="exports/deep_research_agent"
-)
-# → All 12 tests pass
-```

-
-## Phase 1: Generate Tests
-
-### Read the goal
-

-# Extract: goal_id="rigorous-interactive-research"
-# success_criteria: source-diversity (>=5), citation-coverage (100%), report-completeness (90%)

-run_tests(
-    goal_id="rigorous-interactive-research",
-    agent_path="exports/deep_research_agent",
-    fail_fast=True
-)
-```

-    {"test_name": "test_success_citation_coverage", "details": "AssertionError: Report lacks citations"}
-  ]
-}
-```
-
---
-
-## Phase 3: Analyze (Iteration 1)
-
-### Debug the first failure
-
-```python
-debug_test(
-    goal_id="rigorous-interactive-research",
-    test_name="test_success_source_diversity",
-    agent_path="exports/deep_research_agent"
-)
-# Category: ASSERTION_FAILURE — Expected >= 5 sources, got 2
-```
-
-### Find the session and inspect memory
-
-```python
-list_agent_sessions(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    status="completed",
-    limit=1
-)
-# → session_20260209_150000_abc12345
-
-get_agent_session_memory(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    session_id="session_20260209_150000_abc12345",
-    key="research_results"
-)
-# → Only 2 sources found. LLM stopped searching after 2 queries.
-```
-
-### Check LLM behavior in the research node
-
-```python
-query_runtime_log_raw(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    run_id="session_20260209_150000_abc12345",
-    node_id="research"
-)
-# → LLM called web_search twice, got results, immediately called set_output.
-# → Prompt doesn't instruct it to find at least 5 sources.
-```
-
-**Root cause:** The research node's system_prompt doesn't specify minimum source requirements.
-
---
-
-## Phase 4: Fix (Iteration 1)
-
-```python
-Read(file_path="exports/deep_research_agent/nodes/__init__.py")
-
-# Fix the research node prompt
-Edit(
-    file_path="exports/deep_research_agent/nodes/__init__.py",
-    old_string='system_prompt="Search for information on the user\'s topic using web search."',
-    new_string='system_prompt="Search for information on the user\'s topic using web search. You MUST find at least 5 diverse, authoritative sources. Use multiple different search queries with varied keywords. Do NOT call set_output until you have gathered at least 5 distinct sources from different domains."'
-)
-```
-
---
-
-## Phase 5: Recover & Resume (Iteration 1)
-
-The fix is to the `research` node. Since this was a `run_tests` execution (no checkpoints), we re-run from scratch:
-
-```python
-run_tests(
-    goal_id="rigorous-interactive-research",
-    agent_path="exports/deep_research_agent",
-    fail_fast=True
-)
-```
-
-**Result:**
-```json
-{
-  "overall_passed": false,
-  "summary": {"total": 5, "passed": 4, "failed": 1, "pass_rate": "80.0%"},
-  "failures": [
-    {"test_name": "test_success_citation_coverage", "details": "AssertionError: Report lacks citations"}
-  ]
-}
-```
-
-Source diversity now passes. Citation coverage still fails.

-## Phase 3: Analyze (Iteration 2)
-
-```python
-debug_test(
-    goal_id="rigorous-interactive-research",
-    test_name="test_success_citation_coverage",
-    agent_path="exports/deep_research_agent"
-)
-# Category: ASSERTION_FAILURE — Report lacks citations
-
-# Check what the report node produced
-list_agent_sessions(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    status="completed",
-    limit=1
-)
-# → session_20260209_151500_def67890
-
-get_agent_session_memory(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    session_id="session_20260209_151500_def67890",
-    key="report"
-)
-# → Report text exists but uses no numbered references.
-# → Sources are in memory but report node doesn't cite them.
-```
-
-**Root cause:** The report node's prompt doesn't instruct the LLM to include numbered citations.
-
---
-
-## Phase 4: Fix (Iteration 2)
-
-```python
-Edit(
-    file_path="exports/deep_research_agent/nodes/__init__.py",
-    old_string='system_prompt="Write a comprehensive report based on the research findings."',
-    new_string='system_prompt="Write a comprehensive report based on the research findings. You MUST include numbered citations [1], [2], etc. for every factual claim. At the end, include a References section listing all sources with their URLs. Every claim must be traceable to a specific source."'
-)
-```
-
---
-
-## Phase 5: Resume (Iteration 2)
-
-The fix is to the `report` node (the last node). To demonstrate checkpoint recovery, run via CLI:
-
-```bash
-# Run via CLI to get checkpoints
-uv run hive run exports/deep_research_agent --input '{"topic": "climate change effects"}'
-
-# After it runs, find the clean checkpoint before report
-list_agent_checkpoints(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    session_id="session_20260209_152000_ghi34567",
-    is_clean="true"
-)
-# → cp_node_complete_review_152100 (after review, before report)
-
-# Resume — skips intake, research, review entirely
-uv run hive run exports/deep_research_agent \
-  --resume-session session_20260209_152000_ghi34567 \
-  --checkpoint cp_node_complete_review_152100
-```
-
-Only the `report` node re-runs with the fixed prompt, using research data from the checkpoint.
-
---
-
-## Phase 6: Final Verification
-
-```python
-run_tests(
-    goal_id="rigorous-interactive-research",
-    agent_path="exports/deep_research_agent"
-)
-```
-
-**Result:**
-```json
-{
-  "overall_passed": true,
-  "summary": {"total": 5, "passed": 5, "failed": 0, "pass_rate": "100.0%"}
-}
-```
-
-All tests pass.
-
---
-
-## Summary
-
-| Iteration | Failure | Root Cause | Fix | Recovery |
-|-----------|---------|------------|-----|----------|
-| 1 | Source diversity (2 < 5) | Research prompt too vague | Added "at least 5 sources" to prompt | Re-run (no checkpoints) |
-| 2 | No citations in report | Report prompt lacks citation instructions | Added citation requirements | Checkpoint resume (skipped 3 nodes) |
-
-**Key takeaways:**
- Phase 3 analysis (session memory + L3 logs) identified root causes without guessing
- Checkpoint recovery in iteration 2 saved time by skipping 3 expensive nodes
- Final `run_tests` confirms all scenarios pass end-to-end

-# Agent Development Workflow
-
-**THIS IS AN EXECUTABLE WORKFLOW. DO NOT explore the codebase or read source files. ROUTE to the correct skill IMMEDIATELY.**
-
-When this skill is loaded, **ALWAYS use the AskUserQuestion tool** to present options:
-
-```
-Use AskUserQuestion with these options:
- "Build a new agent" → Then invoke /hive-create
- "Test an existing agent" → Then invoke /hive-test
- "Learn agent concepts" → Then invoke /hive-concepts
- "Optimize agent design" → Then invoke /hive-patterns
- "Set up credentials" → Then invoke /hive-credentials
- "Debug a failing agent" → Then invoke /hive-debugger
- "Other" (please describe what you want to achieve)
-```
-
-**DO NOT:** Read source files, explore the codebase, search for code, or do any investigation before routing. The sub-skills handle all of that.
-
---
-
-Complete Standard Operating Procedure (SOP) for building production-ready goal-driven agents.
-
-## Overview
-
-This workflow orchestrates specialized skills to take you from initial concept to production-ready agent:
-
-1. **Understand Concepts** → `/hive-concepts` (optional)
-2. **Build Structure** → `/hive-create`
-3. **Optimize Design** → `/hive-patterns` (optional)
-4. **Setup Credentials** → `/hive-credentials` (if agent uses tools requiring API keys)
-5. **Test & Validate** → `/hive-test`
-6. **Debug Issues** → `/hive-debugger` (if agent fails at runtime)
-
-## When to Use This Workflow
-
-Use this meta-skill when:
- Starting a new agent from scratch
- Unclear which skill to use first
- Need end-to-end guidance for agent development
- Want consistent, repeatable agent builds
-
-**Skip this workflow** if:
- You only need to test an existing agent → use `/hive-test` directly
- You know exactly which phase you're in → use specific skill directly
-
-## Quick Decision Tree
-
-```
-"Need to understand agent concepts" → hive-concepts
-"Build a new agent" → hive-create
-"Optimize my agent design" → hive-patterns
-"Need client-facing nodes or feedback loops" → hive-patterns
-"Set up API keys for my agent" → hive-credentials
-"Test my agent" → hive-test
-"My agent is failing/stuck/has errors" → hive-debugger
-"Not sure what I need" → Read phases below, then decide
-"Agent has structure but needs implementation" → See agent directory STATUS.md
-```
-
-## Phase 0: Understand Concepts (Optional)
-
-**Skill**: `/hive-concepts`
-**Input**: Questions about agent architecture
-
-### When to Use
-
- First time building an agent
- Need to understand node types, edges, goals
- Want to validate tool availability
- Learning about event loop architecture and client-facing nodes
-
-### What This Phase Provides
-
- Architecture overview (Python packages, not JSON)
- Core concepts (Goal, Node, Edge, Event Loop, Judges)
- Tool discovery and validation procedures
- Workflow overview
-
-**Skip this phase** if you already understand agent fundamentals.
-
-## Phase 1: Build Agent Structure
-
-**Skill**: `/hive-create`
-**Input**: User requirements ("Build an agent that...") or a template to start from
-
-### What This Phase Does
-
-Creates the complete agent architecture:
- Package structure (`exports/agent_name/`)
- Goal with success criteria and constraints
- Workflow graph (nodes and edges)
- Node specifications
- CLI interface
- Documentation
-
-### Process
-
-1. **Create package** - Directory structure with skeleton files
-2. **Define goal** - Success criteria and constraints written to agent.py
-3. **Design nodes** - Each node approved and written incrementally
-4. **Connect edges** - Workflow graph with conditional routing
-5. **Finalize** - Agent class, exports, and documentation
-
-### Outputs
-
- ✅ `exports/agent_name/` package created
- ✅ Goal defined in agent.py
- ✅ 3-5 success criteria defined
- ✅ 1-5 constraints defined
- ✅ 5-10 nodes specified in nodes/__init__.py
- ✅ 8-15 edges connecting workflow
- ✅ Validated structure (passes `uv run python -m agent_name validate`)
- ✅ README.md with usage instructions
- ✅ CLI commands (info, validate, run, shell)
-
-### Success Criteria
-
-You're ready for Phase 2 when:
- Agent structure validates without errors
- All nodes and edges are defined
- CLI commands work (info, validate)
- You see: "Agent complete: exports/agent_name/"
-
-### Common Outputs
-
-The hive-create skill produces:
-```
-exports/agent_name/
-├── __init__.py          (package exports)
-├── __main__.py          (CLI interface)
-├── agent.py             (goal, graph, agent class)
-├── nodes/__init__.py    (node specifications)
-├── config.py            (configuration)
-├── implementations.py   (may be created for Python functions)
-└── README.md            (documentation)
-```
-
-### Next Steps
-
-**If structure complete and validated:**
-→ Check `exports/agent_name/STATUS.md` or `IMPLEMENTATION_GUIDE.md`
-→ These files explain implementation options
-→ You may need to add Python functions or MCP tools (not covered by current skills)
-
-**If want to optimize design:**
-→ Proceed to Phase 1.5 (hive-patterns)
-
-**If ready to test:**
-→ Proceed to Phase 2
-
-## Phase 1.5: Optimize Design (Optional)
-
-**Skill**: `/hive-patterns`
-**Input**: Completed agent structure
-
-### When to Use
-
- Want to add client-facing blocking or feedback edges
- Need judge patterns for output validation
- Want fan-out/fan-in (parallel execution)
- Need error handling patterns
- Want best practices guidance
-
-### What This Phase Provides
-
- Client-facing interaction patterns
- Feedback edge routing with nullable output keys
- Judge patterns (implicit, SchemaJudge)
- Fan-out/fan-in parallel execution
- Context management and spillover patterns
- Anti-patterns to avoid
-
-**Skip this phase** if your agent design is straightforward.
-
-## Phase 2: Test & Validate
-
-**Skill**: `/hive-test`
-**Input**: Working agent from Phase 1
-
-### What This Phase Does
-
-Guides the creation and execution of a comprehensive test suite:
- Constraint tests
- Success criteria tests
- Edge case tests
- Integration tests
-
-### Process
-
-1. **Analyze agent** - Read goal, constraints, success criteria
-2. **Generate tests** - The calling agent writes pytest files in `exports/agent_name/tests/` using hive-test guidelines and templates
-3. **User approval** - Review and approve each test
-4. **Run evaluation** - Execute tests and collect results
-5. **Debug failures** - Identify and fix issues
-6. **Iterate** - Repeat until all tests pass
-
-### Outputs
-
- ✅ Test files in `exports/agent_name/tests/`
- ✅ Test report with pass/fail metrics
- ✅ Coverage of all success criteria
- ✅ Coverage of all constraints
- ✅ Edge case handling verified
-
-### Success Criteria
-
-You're done when:
- All tests pass
- All success criteria validated
- All constraints verified
- Agent handles edge cases
- Test coverage is comprehensive
-
-### Next Steps
-
-**Agent ready for:**
- Production deployment
- Integration into larger systems
- Documentation and handoff
- Continuous monitoring
-
-## Phase Transitions
-
-### From Phase 1 to Phase 2
-
-**Trigger signals:**
- "Agent complete: exports/..."
- Structure validation passes
- README indicates implementation complete
-
-**Before proceeding:**
- Verify agent can be imported: `from exports.agent_name import default_agent`
- Check if implementation is needed (see STATUS.md or IMPLEMENTATION_GUIDE.md)
- Confirm agent executes without import errors
-
-### Skipping Phases
-
-**When to skip Phase 1:**
- Agent structure already exists
- Only need to add tests
- Modifying existing agent
-
-**When to skip Phase 2:**
- Prototyping or exploring
- Agent not production-bound
- Manual testing sufficient
-
-## Common Patterns
-
-### Pattern 1: Complete New Build (Simple)
-
-```
-User: "Build an agent that monitors files"
-→ Use /hive-create
-→ Agent structure created
-→ Use /hive-test
-→ Tests created and passing
-→ Done: Production-ready agent
-```
-
-### Pattern 1b: Complete New Build (With Learning)
-
-```
-User: "Build an agent (first time)"
-→ Use /hive-concepts (understand concepts)
-→ Use /hive-create (build structure)
-→ Use /hive-patterns (optimize design)
-→ Use /hive-test (validate)
-→ Done: Production-ready agent
-```
-
-### Pattern 1c: Build from Template
-
-```
-User: "Build an agent based on the deep research template"
-→ Use /hive-create
-→ Select "From a template" path
-→ Pick template, name new agent
-→ Review/modify goal, nodes, graph
-→ Agent exported with customizations
-→ Use /hive-test
-→ Done: Customized agent
-```
-
-### Pattern 2: Test Existing Agent
-
-```
-User: "Test my agent at exports/my_agent"

-→ Use /hive-test directly
-→ Tests created
-→ Done: Validated agent
-```
-
-### Pattern 3: Iterative Development
-
-```
-User: "Build an agent"
-→ Use /hive-create (Phase 1)
-→ Implementation needed (see STATUS.md)
-→ [User implements functions]
-→ Use /hive-test (Phase 2)
-→ Tests reveal bugs
-→ [Fix bugs manually]
-→ Re-run tests
-→ Done: Working agent
-```
-
-### Pattern 4: Agent with Review Loops and HITL Checkpoints
-
-```
-User: "Build an agent with human review and feedback loops"
-→ Use /hive-concepts (learn event loop, client-facing nodes)
-→ Use /hive-create (build structure with feedback edges)

-```
-
-## Troubleshooting
-
-### "Agent structure won't validate"
-
- Check node IDs match between nodes/__init__.py and agent.py
- Verify all edges reference valid node IDs
- Ensure entry_node exists in nodes list
- Run: `PYTHONPATH=exports uv run python -m agent_name validate`
-
-### "Agent has structure but won't run"
-
- Check for STATUS.md or IMPLEMENTATION_GUIDE.md in agent directory
- Implementation may be needed (Python functions or MCP tools)
- This is expected - hive-create creates structure, not implementation
- See implementation guide for completion options
-
-### "Tests are failing"
-
- Review test output for specific failures
- Check agent goal and success criteria
- Verify constraints are met
- Use `/hive-test` to debug and iterate
- Fix agent code and re-run tests
-
-### "Agent is failing at runtime"
-
- Use `/hive-debugger` to analyze runtime logs
- The debugger identifies retry loops, tool failures, and stalled execution
- Get actionable fix recommendations with code changes
- Monitor the agent in real-time during TUI sessions
-
-### "Not sure which phase I'm in"
-
-Run these checks:
-
-```bash
-# Check if agent structure exists
-ls exports/my_agent/agent.py
-
-# Check if it validates
-PYTHONPATH=exports uv run python -m my_agent validate
-
-# Check if tests exist
-ls exports/my_agent/tests/
-
-# If structure exists and validates → Phase 2 (testing)
-# If structure doesn't exist → Phase 1 (building)
-# If tests exist but failing → Debug phase
-```
-
-## Best Practices
-
-### For Phase 1 (Building)
-
-1. **Start with clear requirements** - Know what the agent should do
-2. **Define success criteria early** - Measurable goals drive design
-3. **Keep nodes focused** - One responsibility per node
-4. **Use descriptive names** - Node IDs should explain purpose
-5. **Validate incrementally** - Check structure after each major addition
-
-### For Phase 2 (Testing)
-
-1. **Test constraints first** - Hard requirements must pass
-2. **Mock external dependencies** - Use mock mode for LLMs/APIs
-3. **Cover edge cases** - Test failures, not just success paths
-4. **Iterate quickly** - Fix one test at a time
-5. **Document test patterns** - Future tests follow same structure
-
-### General Workflow
-
-1. **Use version control** - Git commit after each phase
-2. **Document decisions** - Update README with changes
-3. **Keep iterations small** - Build → Test → Fix → Repeat
-4. **Preserve working states** - Tag successful iterations
-5. **Learn from failures** - Failed tests reveal design issues
-
-## Exit Criteria
-
-You're done with the workflow when:
-
-✅ Agent structure validates
-✅ All tests pass
-✅ Success criteria met
-✅ Constraints verified
-✅ Documentation complete
-✅ Agent ready for deployment

-2. **Build** with `/hive-create` → Get validated structure
-3. **Optimize** with `/hive-patterns` → Apply best practices (optional)
-4. **Configure** with `/hive-credentials` → Set up API keys (if needed)
-5. **Test** with `/hive-test` → Get verified functionality
-6. **Debug** with `/hive-debugger` → Fix runtime issues (if needed)
-

-# Example: File Monitor Agent
-
-This example shows the complete /hive workflow in action for building a file monitoring agent.
-
-## Initial Request
-
-```
-User: "Build an agent that monitors ~/Downloads and copies new files to ~/Documents"
-```
-
-## Phase 1: Building (20 minutes)
-
-### Step 1: Create Structure
-
-Agent invokes `/hive-create` skill and:
-
-1. Creates `exports/file_monitor_agent/` package
-2. Writes skeleton files (__init__.py, __main__.py, agent.py, etc.)
-
-**Output**: Package structure visible immediately
-
-### Step 2: Define Goal
-
-```python
-goal = Goal(
-    id="file-monitor-copy",
-    name="Automated File Monitor & Copy",
-    success_criteria=[
-        # 100% detection rate
-        # 100% copy success
-        # 100% conflict resolution
-        # >99% uptime
-    ],
-    constraints=[
-        # Preserve originals
-        # Handle errors gracefully
-        # Track state
-        # Respect permissions
-    ]
-)
-```
-
-**Output**: Goal written to agent.py
-
-### Step 3: Design Nodes
-
-7 nodes approved and written incrementally:
-
-1. `initialize-state` - Set up tracking
-2. `list-downloads` - Scan directory
-3. `identify-new-files` - Find new files
-4. `check-for-new-files` - Router
-5. `copy-files` - Copy with conflict resolution
-6. `update-state` - Mark as processed
-7. `wait-interval` - Sleep between cycles
-
-**Output**: All nodes in nodes/__init__.py
-
-### Step 4: Connect Edges
-
-8 edges connecting the workflow loop:
-
-```
-initialize → list → identify → check
-                                ↓  ↓
-                              copy  wait
-                                ↓    ↑
-                              update ↓
-                                ↓    ↓
-                              wait → list (loop)
-```
-
-**Output**: Edges written to agent.py
-
-### Step 5: Finalize
-
-```bash
-$ PYTHONPATH=exports uv run python -m file_monitor_agent validate
-✓ Agent is valid
-
-$ PYTHONPATH=exports uv run python -m file_monitor_agent info
-Agent: File Monitor & Copy Agent
-Nodes: 7
-Edges: 8
-```
-
-**Phase 1 Complete**: Structure validated ✅
-
-### Status After Phase 1
-
-```

-```
-
-**Note**: Implementation gap exists - data flow needs connection (covered in STATUS.md)
-
-## Phase 2: Testing (25 minutes)
-
-### Step 1: Analyze Agent
-
-Agent invokes `/hive-test` skill and:
-
-1. Reads goal from `exports/file_monitor_agent/agent.py`
-2. Identifies 4 success criteria to test
-3. Identifies 4 constraints to verify
-4. Plans test coverage
-
-### Step 2: Generate Tests
-
-Creates test files:
-
-```
-exports/file_monitor_agent/tests/
-├── conftest.py              (fixtures)
-├── test_constraints.py      (4 constraint tests)
-├── test_success_criteria.py (4 success tests)
-└── test_edge_cases.py       (error handling)
-```
-
-Tests approved incrementally by user.
-
-### Step 3: Run Tests
-
-```bash
-$ PYTHONPATH=exports uv run pytest exports/file_monitor_agent/tests/

-## Final Output
-
-**Production-Ready Agent:**
-
-```bash
-# Run the agent
-./RUN_AGENT.sh
-
-# Or manually
-PYTHONPATH=exports uv run python -m file_monitor_agent run
-```
-
-**Capabilities:**
- Monitors ~/Downloads continuously
- Copies new files to ~/Documents
- Resolves conflicts with timestamps
- Handles errors gracefully
- Tracks processed files
- Runs as background service
-
-**Total Time**: ~45 minutes from concept to production
-
-## Key Learnings
-
-1. **Incremental building** - Files written immediately, visible throughout
-2. **Validation early** - Structure validated before moving to implementation
-3. **Test-driven** - Tests reveal real behavior
-4. **Documentation included** - README, STATUS, and guides auto-generated
-5. **Repeatable process** - Same workflow for any agent type
-
-## Variations
-
-**For simpler agents:**
- Fewer nodes (3-5 instead of 7)
- Simpler workflow (linear instead of looping)
- Faster build time (10-15 minutes)
-
-**For complex agents:**
- More nodes (10-15+)
- Multiple subgraphs
- Pause/resume points for human-in-the-loop
- Longer build time (45-60 minutes)
-
-The workflow scales to your needs!

+# Integration Test Reporting Skill
+
+Run the Level 2 dummy agent integration test suite and produce a detailed HTML report with per-test input → outcome analysis.
+
+## Trigger
+
+User wants to run integration tests and see results:
+- `/test-reporting`
+- `/test-reporting test_component_queen_live.py`
+- `/test-reporting --all`
+
+## SOP: Running Tests
+
+### Step 1: Select Scope
+
+If the user provides a specific test file or pattern, use it. Otherwise run the full suite.
+
+```bash
+# Full suite
+cd core && echo "1" | uv run python tests/dummy_agents/run_all.py --interactive 2>&1
+
+# Specific file (requires manual provider setup)
+cd core && uv run python -c "
+import sys
+sys.path.insert(0, '.')
+from tests.dummy_agents.run_all import detect_available
+from tests.dummy_agents.conftest import set_llm_selection
+
+avail = detect_available()
+claude = [p for p in avail if 'Claude Code' in p['name']]
+if not claude:
+    avail_names = [p['name'] for p in avail]
+    raise RuntimeError(f'No Claude Code subscription. Available: {avail_names}')
+provider = claude[0]
+set_llm_selection(
+    model=provider['model'],
+    api_key=provider['api_key'],
+    extra_headers=provider.get('extra_headers'),
+    api_base=provider.get('api_base'),
+)
+
+import pytest
+sys.exit(pytest.main([
+    'tests/dummy_agents/TEST_FILE_HERE',
+    '-v', '--override-ini=asyncio_mode=auto', '--no-header', '--tb=long',
+    '--log-cli-level=WARNING', '--junitxml=/tmp/hive_test_results.xml',
+]))
+"
+```
+
+### Step 2: Collect Results
+
+After the test run completes, collect:
+1. **JUnit XML** from `--junitxml` output (if available)
+2. **stdout/stderr** from the run
+3. **Summary table** from `run_all.py` output (the Unicode table)
+
+### Step 3: Generate HTML Report
+
+Write the report to `/tmp/hive_integration_test_report.html`.
+
+The report MUST include these sections:
+
+#### Header
+- Run timestamp (ISO 8601)
+- Provider used (model name, source)
+- Total tests / passed / failed / skipped
+- Total wall-clock time
+- Overall verdict: PASS (all green) or FAIL (with count)
+
+#### Per-Test Table
+
+For EVERY test (not just failures), include a row with:
+
+| Column | Description |
+|--------|-------------|
+| Component | Test file grouping (e.g., `component_queen_live`) |
+| Test Name | Function name (e.g., `test_queen_starts_in_planning_without_worker`) |
+| Status | PASS / FAIL / SKIP / ERROR with color badge |
+| Duration | Wall-clock seconds |
+| What | One-line description of what the test verifies |
+| How | How it works (setup → action → assertion) |
+| Why | Why this test matters (what bug/behavior it catches) |
+| Input | The input data or configuration (graph spec, initial prompt, phase, etc.) |
+| Expected Outcome | What the test asserts |
+| Actual Outcome | What actually happened (PASS: matches expected / FAIL: actual vs expected) |
+| Failure Detail | For failures only: full traceback + diagnosis |
+
+#### What / How / Why Descriptions
+
+These MUST be derived from the test function's docstring and code. Read each test file to extract:
+- **What**: From the docstring first line
+- **How**: From the test body (what fixtures, what graph, what assertions)
+- **Why**: From the docstring body or "Why this matters" section in the test module
+
+Use these mappings for the component test files:
+
+```
+test_component_llm.py          → "LLM Provider" — streaming, tool calling, tokens
+test_component_tools.py        → "Tool Registry + MCP" — connection, execution
+test_component_event_loop.py   → "EventLoopNode" — iteration, output, stall
+test_component_edges.py        → "Edge Evaluation" — conditional, priority
+test_component_conversation.py → "Conversation Persistence" — storage, cursor
+test_component_escalation.py   → "Escalation Flow" — worker→queen signaling
+test_component_continuous.py   → "Continuous Mode" — conversation threading
+test_component_queen.py        → "Queen Phase (Unit)" — phase state, tools, events
+test_component_queen_live.py   → "Queen Phase (Live)" — real queen, real LLM
+test_component_queen_state_machine.py → "Queen State Machine" — edge cases, races
+test_component_worker_comms.py → "Worker Communication" — events, data flow
+test_component_strict_outcomes.py → "Strict Outcomes" — exact path, output, quality
+```
+
+#### HTML Template
+
+Use this structure:
+
+```html

+```
+
+### Step 4: Output
+
+1. Write the HTML file to `/tmp/hive_integration_test_report.html`
+2. Print the file path so the user can open it
+3. Print a concise summary to the terminal:
+   ```
+   Test Report: /tmp/hive_integration_test_report.html
+   Result: 74/76 PASSED (2 failures)
+   Failures:
+     - parallel_merge::test_parallel_disjoint_output_keys
+     - worker::test_worker_timestamped_note_artifact
+   ```
+
+## Key Rules
+
+1. ALWAYS use `--junitxml` when running pytest to get structured results
+2. ALWAYS read the test source files to populate What/How/Why columns — do not guess
+3. For Input/Expected/Actual, extract from the test's graph spec, assertions, and result
+4. Color-code everything: green for pass, red for fail, amber for skip
+5. Include the full traceback for failures in a scrollable `<div class="detail">`
+6. Group tests by component (file name) with a visual separator
+7. The report must be self-contained HTML (no external CSS/JS dependencies)

-This project uses ruff for Python linting and formatting.
-
-Rules:
- Line length: 100 characters
- Python target: 3.11+
- Use double quotes for strings
- Sort imports with isort (ruff I rules): stdlib, third-party, first-party (framework), local
- Combine as-imports
- Use type hints on all function signatures
- Use `from __future__ import annotations` for modern type syntax
- Raise exceptions with `from` in except blocks (B904)
- No unused imports (F401), no unused variables (F841)
- Prefer list/dict/set comprehensions over map/filter (C4)
-
-Run `make lint` to auto-fix, `make check` to verify without modifying files.
-Run `make format` to apply ruff formatting.
-
-The ruff config lives in core/pyproject.toml under [tool.ruff].

+# Repository Guidelines
+
+Shared agent instructions for this workspace.
+
+## Coding Agent Notes
+
+- 
+- When working on a GitHub Issue or PR, print the full URL at the end of the task.
+- When answering questions, respond with high-confidence answers only: verify in code; do not guess.
+- Do not update dependencies casually. Version bumps, patched dependencies, overrides, or vendored dependency changes require explicit approval.
+- Add brief comments for tricky logic. Keep files reasonably small when practical; split or refactor large files instead of growing them indefinitely.
+- If shared guardrails are available locally, review them; otherwise follow this repo's guidance.
+- Use `uv` for Python execution and package management. Do not use `python` or `python3` directly unless the user explicitly asks for it.
+- Prefer `uv run` for scripts and tests, and `uv pip` for package operations.
+
+
+## Multi-Agent Safety
+
+- Do not create, apply, or drop `git stash` entries unless explicitly requested.
+- Do not create, remove, or modify `git worktree` checkouts unless explicitly requested.
+- Do not switch branches or check out a different branch unless explicitly requested.
+- When the user says `push`, you may `git pull --rebase` to integrate latest changes, but never discard other in-progress work.
+- When the user says `commit`, commit only your changes. When the user says `commit all`, commit everything in grouped chunks.
+- When you see unrecognized files or unrelated changes, keep going and focus on your scoped changes.
+
+## Change Hygiene
+
+- If staged and unstaged diffs are formatting-only, resolve them without asking.
+- If a commit or push was already requested, include formatting-only follow-up changes in that same commit when practical.
+- Only stop to ask for confirmation when changes are semantic and may alter behavior.

+# Release Notes
+
+## v0.7.1
+
+**Release Date:** March 13, 2026
+**Tag:** v0.7.1
+
+### Chrome-Native Browser Control
+
+v0.7.1 replaces Playwright with direct Chrome DevTools Protocol (CDP) integration. The GCU now launches the user's system Chrome via `open -n` on macOS, connects over CDP, and manages browser lifecycle end-to-end -- no extra browser binary required.
+
+---
+
+### Highlights
+
+#### System Chrome via CDP
+
+The entire GCU browser stack has been rewritten:
+
+- **Chrome finder & launcher** -- New `chrome_finder.py` discovers installed Chrome and `chrome_launcher.py` manages process lifecycle with `--remote-debugging-port`
+- **Coexist with user's browser** -- `open -n` on macOS launches a separate Chrome instance so the user's tabs stay untouched
+- **Dynamic viewport sizing** -- Viewport auto-sizes to the available display area, suppressing Chrome warning bars
+- **Orphan cleanup** -- Chrome processes are killed on GCU server shutdown to prevent leaks
+- **`--no-startup-window`** -- Chrome launches headlessly by default until a page is needed
+
+#### Per-Subagent Browser Isolation
+
+Each GCU subagent gets its own Chrome user-data directory, preventing cookie/session cross-contamination:
+
+- Unique browser profiles injected per subagent
+- Profiles cleaned up after top-level GCU node execution
+- Tab origin and age metadata tracked per subagent
+
+#### Dummy Agent Testing Framework
+
+A comprehensive test suite for validating agent graph patterns without LLM calls:
+
+- 8 test modules covering echo, pipeline, branch, parallel merge, retry, feedback loop, worker, and GCU subagent patterns
+- Shared fixtures and a `run_all.py` runner for CI integration
+- Subagent lifecycle tests
+
+---
+
+### What's New
+
+#### GCU Browser
+
+- **Switch from Playwright to system Chrome via CDP** -- Direct CDP connection replaces Playwright dependency. (@bryanadenhq)
+- **Chrome finder and launcher modules** -- `chrome_finder.py` and `chrome_launcher.py` for cross-platform Chrome discovery and process management. (@bryanadenhq)
+- **Dynamic viewport sizing** -- Auto-size viewport and suppress Chrome warning bar. (@bryanadenhq)
+- **Per-subagent browser profile isolation** -- Unique user-data directories per subagent with cleanup. (@bryanadenhq)
+- **Tab origin/age metadata** -- Track which subagent opened each tab and when. (@bryanadenhq)
+- **`browser_close_all` tool** -- Bulk tab cleanup for agents managing many pages. (@bryanadenhq)
+- **Auto-track popup pages** -- Popups are automatically captured and tracked. (@bryanadenhq)
+- **Auto-snapshot from browser interactions** -- Browser interaction tools return screenshots automatically. (@bryanadenhq)
+- **Kill orphaned Chrome processes** -- GCU server shutdown cleans up lingering Chrome instances. (@bryanadenhq)
+- **`--no-startup-window` Chrome flag** -- Prevent empty window on launch. (@bryanadenhq)
+- **Launch Chrome via `open -n` on macOS** -- Coexist with the user's running browser. (@bryanadenhq)
+
+#### Framework & Runtime
+
+- **Session resume fix for new agents** -- Correctly resume sessions when a new agent is loaded. (@bryanadenhq)
+- **Queen upsert fix** -- Prevent duplicate queen entries on session restore. (@bryanadenhq)
+- **Anchor worker monitoring to queen's session ID on cold-restore** -- Worker monitors reconnect to the correct queen after restart. (@bryanadenhq)
+- **Update meta.json when loading workers** -- Worker metadata stays in sync with runtime state. (@RichardTang-Aden)
+- **Generate worker MCP file correctly** -- Fix MCP config generation for spawned workers. (@RichardTang-Aden)
+- **Share event bus so tool events are visible to parent** -- Tool execution events propagate up to parent graphs. (@bryanadenhq)
+- **Subagent activity tracking in queen status** -- Queen instructions include live subagent status. (@bryanadenhq)
+- **GCU system prompt updates** -- Auto-snapshots, batching, popup tracking, and close_all guidance. (@bryanadenhq)
+
+#### Frontend
+
+- **Loading spinner in draft panel** -- Shows spinner during planning phase instead of blank panel. (@bryanadenhq)
+- **Fix credential modal errors** -- Modal no longer eats errors; banner stays visible. (@bryanadenhq)
+- **Fix credentials_required loop** -- Stop clearing the flag on modal close to prevent infinite re-prompting. (@bryanadenhq)
+- **Fix "Add tab" dropdown overflow** -- Dropdown no longer hidden when many agents are open. (@prasoonmhwr)
+
+#### Testing
+
+- **Dummy agent test framework** -- 8 test modules (echo, pipeline, branch, parallel merge, retry, feedback loop, worker, GCU subagent) with shared fixtures and CI runner. (@bryanadenhq)
+- **Subagent lifecycle tests** -- Validate subagent spawn and completion flows. (@bryanadenhq)
+
+#### Documentation & Infrastructure
+

+
+**Release Date:** February 18, 2026
+**Tag:** v0.5.1
+
+### The Hive Gets a Brain
+
+v0.5.1 is our most ambitious release yet. Hive agents can now **build other agents** -- the new Hive Coder meta-agent writes, tests, and fixes agent packages from natural language. The runtime grows multi-graph support so one session can orchestrate multiple agents simultaneously. The TUI gets a complete overhaul with an in-app agent picker, live streaming, and seamless escalation to the Coder. And we're now provider-agnostic: Claude Code subscriptions, OpenAI-compatible endpoints, and any LiteLLM-supported model work out of the box.
+
+---
+
+### Highlights
+
+#### Hive Coder -- The Agent That Builds Agents
+
+A native meta-agent that lives inside the framework at `core/framework/agents/hive_coder/`. Give it a natural-language specification and it produces a complete agent package -- goal definition, node prompts, edge routing, MCP tool wiring, tests, and all boilerplate files.
+
+```bash
+# Launch the Coder directly
+hive code
+
+# Or escalate from any running agent (TUI)
+Ctrl+E  # or /coder in chat
+```
+
+The Coder ships with:
+
+- **Reference documentation** -- anti-patterns, construction guide, and design patterns baked into its system prompt
+- **Guardian watchdog** -- an event-driven monitor that catches agent failures and triggers automatic remediation
+- **Coder Tools MCP server** -- file I/O, fuzzy-match editing, git snapshots, and sandboxed shell execution (`tools/coder_tools_server.py`)
+- **Test generation** -- structural tests for forever-alive agents that don't hang on `runner.run()`
+
+#### Multi-Graph Agent Runtime
+
+`AgentRuntime` now supports loading, managing, and switching between multiple agent graphs within a single session. Six new lifecycle tools give agents (and the TUI) full control:
+
+```python
+# Load a second agent into the runtime
+await runtime.add_graph("exports/deep_research_agent")
+
+# Tools available to agents:
+# load_agent, unload_agent, start_agent, restart_agent, list_agents, get_user_presence
+```
+
+The Hive Coder uses multi-graph internally -- when you escalate from a worker agent, the Coder loads as a separate graph while the worker stays alive in the background.
+
+#### TUI Revamp
+
+The Terminal UI gets a ground-up rebuild with five major additions:
+
+- **Agent Picker** (Ctrl+A) -- tabbed modal screen for browsing Your Agents, Framework agents, and Examples with metadata badges (node count, tool count, session count, tags)
+- **Runtime-optional startup** -- TUI launches without a pre-loaded agent, showing the picker on first open
+- **Live streaming pane** -- dedicated RichLog widget shows LLM tokens as they arrive, replacing the old one-token-per-line display
+- **PDF attachments** -- `/attach` and `/detach` commands with native OS file dialog (macOS, Linux, Windows)
+- **Multi-graph commands** -- `/graphs`, `/graph <id>`, `/load <path>`, `/unload <id>` for managing agent graphs in-session
+
+#### Provider-Agnostic LLM Support
+
+Hive is no longer Anthropic-only. v0.5.1 adds first-class support for:
+
+- **Claude Code subscriptions** -- `use_claude_code_subscription: true` in `~/.hive/configuration.json` reads OAuth tokens from `~/.claude/.credentials.json` with automatic refresh
+- **OpenAI-compatible endpoints** -- `api_base` config routes traffic through any compatible API (Azure OpenAI, vLLM, Ollama, etc.)
+- **Any LiteLLM model** -- `RuntimeConfig` now passes `api_key`, `api_base`, and `extra_kwargs` through to LiteLLM
+
+The quickstart script auto-detects Claude Code subscriptions and ZAI Code installations.
+
+---
+
+### What's New
+
+#### Architecture & Runtime
+
+- **Hive Coder meta-agent** -- Natural-language agent builder with reference docs, guardian watchdog, and `hive code` CLI command. (@TimothyZhang7)
+- **Multi-graph agent sessions** -- `add_graph`/`remove_graph` on AgentRuntime with 6 lifecycle tools (`load_agent`, `unload_agent`, `start_agent`, `restart_agent`, `list_agents`, `get_user_presence`). (@TimothyZhang7)
+- **Claude Code subscription support** -- OAuth token refresh via `use_claude_code_subscription` config, auto-detection in quickstart, LiteLLM header patching. (@TimothyZhang7)
+- **OpenAI-compatible endpoint support** -- `api_base` and `extra_kwargs` in `RuntimeConfig` for any OpenAI-compatible API. (@TimothyZhang7)
+- **Remove deprecated node types** -- Delete `FlexibleGraphExecutor`, `WorkerNode`, `HybridJudge`, `CodeSandbox`, `Plan`, `FunctionNode`, `LLMNode`, `RouterNode`. Deprecated types (`llm_tool_use`, `llm_generate`, `function`, `router`, `human_input`) now raise `RuntimeError` with migration guidance. (@TimothyZhang7)
+- **Interactive credential setup** -- Guided `CredentialSetupSession` with health checks and encrypted storage, accessible via `hive setup-credentials` or automatic prompting on credential errors. (@RichardTang-Aden)
+- **Pre-start confirmation prompt** -- Interactive prompt before agent execution allowing credential updates or abort. (@RichardTang-Aden)
+- **Event bus multi-graph support** -- `graph_id` on events, `filter_graph` on subscriptions, `ESCALATION_REQUESTED` event type, `exclude_own_graph` filter. (@TimothyZhang7)
+
+#### TUI Improvements
+
+- **In-app agent picker** (Ctrl+A) -- Tabbed modal for browsing agents with metadata badges (nodes, tools, sessions, tags). (@TimothyZhang7)
+- **Runtime-optional TUI startup** -- Launches without a pre-loaded agent, shows agent picker on startup. (@TimothyZhang7)
+- **Hive Coder escalation** (Ctrl+E) -- Escalate to Hive Coder and return; also available via `/coder` and `/back` chat commands. (@TimothyZhang7)
+- **PDF attachment support** -- `/attach` and `/detach` commands with native OS file dialog. (@TimothyZhang7)
+- **Streaming output pane** -- Dedicated RichLog widget for live LLM token streaming. (@TimothyZhang7)
+- **Multi-graph TUI commands** -- `/graphs`, `/graph <id>`, `/load <path>`, `/unload <id>`. (@TimothyZhang7)
+- **Agent Guardian watchdog** -- Event-driven monitor that catches secondary agent failures and triggers automatic remediation, with `--no-guardian` CLI flag. (@TimothyZhang7)

+#### Infrastructure
+
+- **Default node type → `event_loop`** -- `NodeSpec.node_type` defaults to `"event_loop"` instead of `"llm_tool_use"`. (@TimothyZhang7)
+- **Default `max_node_visits` → 0 (unlimited)** -- Nodes default to unlimited visits, reducing friction for feedback loops and forever-alive agents. (@TimothyZhang7)
+- **Remove `function` field from NodeSpec** -- Follows deprecation of `FunctionNode`. (@TimothyZhang7)
+- **LiteLLM OAuth patch** -- Correct header construction for OAuth tokens (remove `x-api-key` when Bearer token is present). (@TimothyZhang7)
+- **Orchestrator config centralization** -- Reads `api_key`, `api_base`, `extra_kwargs` from centralized `~/.hive/configuration.json`. (@TimothyZhang7)
+- **System prompt datetime injection** -- All system prompts now include current date/time for time-aware agent behavior. (@TimothyZhang7)
+- **Utils module exports** -- Proper `__init__.py` exports for the utils module. (@Siddharth2624)
+- **Increased default max_tokens** -- Opus 4.6 defaults to 32768, Sonnet 4.5 to 16384 (up from 8192). (@TimothyZhang7)

+
+### Documentation
+
+- Clarify installation and prevent root pip install misuse (@paarths-collab)
+
+---
+
+### Agent Updates
+
+- **Email Inbox Management** -- Consolidate `gmail_inbox_guardian` and `inbox_management` into a single unified agent with updated prompts and config. (@RichardTang-Aden, @bryanadenhq)
+- **Job Hunter** -- Updated node prompts, config, and agent metadata; added PDF resume selection. (@bryanadenhq)
+- **Deep Research Agent** -- Revised node implementations with updated prompts and output handling.
+- **Tech News Reporter** -- Revised node prompts for improved output quality.

+
+---
+
+### Breaking Changes
+
+- **Deprecated node types raise `RuntimeError`** -- `llm_tool_use`, `llm_generate`, `function`, `router`, `human_input` now fail instead of warning. Migrate to `event_loop`.
+- **`NodeSpec.node_type` defaults to `"event_loop"`** (was `"llm_tool_use"`)
+- **`NodeSpec.max_node_visits` defaults to `0` / unlimited** (was `1`)

+
+```bash
+git pull origin main
+uv sync
+```
+
+#### Migration Guide
+
+If your agents use deprecated node types, update them:
+
+```python
+# Before (v0.5.0) -- these now raise RuntimeError
+NodeSpec(node_type="llm_tool_use", ...)
+NodeSpec(node_type="function", function=my_func, ...)
+
+# After (v0.5.1) -- use event_loop for everything
+NodeSpec(node_type="event_loop", ...)  # or just omit node_type (it's the default now)
+```
+
+If your agents set `max_node_visits=1` explicitly, they'll still work. The only change is the _default_ -- new agents without an explicit value now get unlimited visits.
+
+To try the new Hive Coder:
+
+```bash
+# Launch Coder directly
+hive code
+
+# Or from TUI -- press Ctrl+E to escalate
+hive tui

+
 ## Overview

-Build autonomous, reliable, self-improving AI agents without hardcoding workflows. Define your goal through conversation with a coding agent, and the framework generates a node graph with dynamically created connection code. When things break, the framework captures failure data, evolves the agent through the coding agent, and redeploys. Built-in human-in-the-loop nodes, credential management, and real-time monitoring give you control without sacrificing adaptability.
+OpenHive is a zero-setup, model-agnostic execution harness that dynamically generates multi-agent topologies to tackle complex, long-running business workflows without requiring any orchestration boilerplate. By simply defining your objective, the runtime compiles a strict, graph-based execution DAG that safely coordinates specialized agents to execute concurrent tasks in parallel. Backed by persistent, role-based memory that intelligently evolves with your project's context, OpenHive ensures deterministic fault tolerance, deep state observability, and seamless asynchronous execution across whichever underlying LLMs you choose to plug in.

 ## Who Is Hive For?

-Hive is designed for developers and teams who want to build **production-grade AI agents** without manually wiring complex workflows.
+Hive is the multi-agent harness layer for teams moving AI agents from prototype to production. Single agents like Openclaw and Cowork can finish personal jobs pretty well but lack the rigor to fulfil business processes. 

 Hive is a good fit if you:

 - Want AI agents that **execute real business processes**, not demos
- Prefer **goal-driven development** over hardcoded workflows
+- Need a **runtime that handles state, recovery, and parallel execution** at scale
 - Need **self-healing and adaptive agents** that improve over time
 - Require **human-in-the-loop control**, observability, and cost limits
- Plan to run agents in **production environments**
+- Plan to run agents in **production** where uptime, cost, and auditability matter

 Hive may not be the best fit if you’re only experimenting with simple agent chains or one-off scripts.

 ## When Should You Use Hive?

-Use Hive when you need:
+Use Hive when the bottleneck is no longer the model but the harness around it:

- Long-running, autonomous agents
- Strong guardrails, process, and controls
- Continuous improvement based on failures
- Multi-agent coordination
- A framework that evolves with your goals
+- Long-running agents that need **state persistence and crash recovery**
+- Production workloads requiring **cost enforcement, observability, and audit trails**
+- Agents that **self-heal** through failure capture and graph evolution
+- Multi-agent coordination with **session isolation and shared buffers**
+- A framework that **scales with model improvements** rather than fighting them

-##  Coding Agent Support
-### Opencode 
-Hive includes native support for [Opencode](https://github.com/opencode-ai/opencode).
+Click "Try a sample agent" and check the templates. You can run a template directly or choose to build your version on top of the existing template.

-1. **Setup:** Run the quickstart script 
-2. **Launch:** Open Opencode in the project root.
-3. **Activate:** Type `/hive` in the chat to switch to the Hive Agent.
-4. **Verify:** Ask the agent *"List your tools"* to confirm the connection.
+### Run Agents

-The agent has access to all Hive skills and can scaffold agents, add tools, and debug workflows directly from the chat.
+Now you can run an agent by selecting the agent (either an existing agent or example agent). You can click the Run button on the top left, or talk to the queen agent and it can run the agent for you.

-## Features
-
- **[Goal-Driven Development](docs/key_concepts/goals_outcome.md)** - Define objectives in natural language; the coding agent generates the agent graph and connection code to achieve them
- **[Adaptiveness](docs/key_concepts/evolution.md)** - Framework captures failures, calibrates according to the objectives, and evolves the agent graph
- **[Dynamic Node Connections](docs/key_concepts/graph.md)** - No predefined edges; connection code is generated by any capable LLM based on your goals
- **SDK-Wrapped Nodes** - Every node gets shared memory, local RLM memory, monitoring, tools, and LLM access out of the box
- **[Human-in-the-Loop](docs/key_concepts/graph.md#human-in-the-loop)** - Intervention nodes that pause execution for human input with configurable timeouts and escalation
- **Real-time Observability** - WebSocket streaming for live monitoring of agent execution, decisions, and node-to-node communication
- **Interactive TUI Dashboard** - Terminal-based dashboard with live graph view, event log, and chat interface for agent interaction
- **Cost & Budget Control** - Set spending limits, throttles, and automatic model degradation policies
- **Production-Ready** - Self-hostable, built for scale and reliability

+## Why Hive

-## Why Aden
-
-Hive focuses on generating agents that run real business processes rather than generic agents. Instead of requiring you to manually design workflows, define agent interactions, and handle failures reactively, Hive flips the paradigm: **you describe outcomes, and the system builds itself**—delivering an outcome-driven, adaptive experience with an easy-to-use set of tools and integrations.

-## Run Agents
-
-The `hive` CLI is the primary interface for running agents.
-
-```bash
-# Browse and run agents interactively (Recommended)
-hive tui
-
-# Run a specific agent directly
-hive run exports/my_agent --input '{"task": "Your input here"}'
-
-# Run a specific agent with the TUI dashboard
-hive run exports/my_agent --tui
-
-# Interactive REPL
-hive shell
-```
-
-The TUI scans both `exports/` and `examples/templates/` for available agents.
-
-> **Using Python directly (alternative):** You can also run agents with `PYTHONPATH=exports uv run python -m agent_name run --input '{...}'`
-
-See [environment-setup.md](docs/environment-setup.md) for complete setup instructions.

 **Q: What makes Hive different from other agent frameworks?**

-Hive generates your entire agent system from natural language goals using a coding agent—you don't hardcode workflows or manually define graphs. When agents fail, the framework automatically captures failure data, [evolves the agent graph](docs/key_concepts/evolution.md), and redeploys. This self-improving loop is unique to Aden.
+Hive is an agent harness, not just an orchestration framework. It provides the production runtime layer — session isolation, checkpoint-based crash recovery, cost enforcement, real-time observability, and human-in-the-loop controls — that makes agents reliable enough to run real workloads. On top of that, Hive generates your entire agent system from natural language goals and automatically [evolves the graph](docs/key_concepts/evolution.md) when agents fail. The combination of a robust harness with self-improving generation is what sets Hive apart.

 **Q: Is Hive open-source?**

 Yes, Hive is fully open-source under the Apache License 2.0. We actively encourage community contributions and collaboration.

-**Q: Can Hive handle complex, production-scale use cases?**
-
-Yes. Hive is explicitly designed for production environments with features like automatic failure recovery, real-time observability, cost controls, and horizontal scaling support. The framework handles both simple automations and complex multi-agent workflows.

-**Q: When will my team start seeing results from Aden's adaptive agents?**
+## Star History

-Aden's adaptation loop begins working from the first execution. When an agent fails, the framework captures the failure data, helping developers evolve the agent graph through the coding agent. How quickly this translates to measurable results depends on the complexity of your use case, the quality of your goal definitions, and the volume of executions generating feedback.
-
-**Q: How does Hive compare to other agent frameworks?**
-
-Hive focuses on generating agents that run real business processes, rather than generic agents. This vision emphasizes outcome-driven design, adaptability, and an easy-to-use set of tools and integrations.

-
-#### `add_evaluation_rule`
-Add a rule for the HybridJudge to evaluate node outputs.
-
-**Parameters:**
- `rule_id` (string, required): Unique rule identifier
- `description` (string, required): What this rule checks
- `condition` (string, required): Python expression to evaluate
- `action` (string, required): Action to take: `accept`, `retry`, `escalate`
- `priority` (integer, optional): Rule priority (default: 0)
- `feedback_template` (string, optional): Feedback message template
-
-**Condition Examples:**
- `'result.get("success") == True'` - Check for success flag
- `'result.get("error_type") == "timeout"'` - Check error type
- `'len(result.get("data", [])) > 0'` - Check for non-empty data
-
-**Example:**
-```json
-{
-  "rule_id": "timeout_retry",
-  "description": "Retry on timeout errors",
-  "condition": "result.get('error_type') == 'timeout'",
-  "action": "retry",
-  "priority": 10,
-  "feedback_template": "Timeout occurred, retrying..."
-}
-```
-
-#### `list_evaluation_rules`
-List all configured evaluation rules.
-
-#### `remove_evaluation_rule`

 uv pip install -e .
 ```

-## MCP Server Setup
+## Agent Building

-The framework includes an MCP (Model Context Protocol) server for building agents. To set up the MCP server:
+Agent scaffolding is handled by the `coder-tools` MCP server (in `tools/coder_tools_server.py`), which provides the `initialize_and_build_agent` tool and related utilities. The package generation logic lives directly in `tools/coder_tools_server.py`.

-### Automated Setup
-
-**Using bash (Linux/macOS):**
-```bash
-./setup_mcp.sh
-```
-
-**Using Python (cross-platform):**
-```bash
-python setup_mcp.py
-```
-
-The setup script will:
-1. Install the framework package
-2. Install MCP dependencies (mcp, fastmcp)
-3. Create/verify `.mcp.json` configuration
-4. Test the MCP server module
-
-### Manual Setup
-
-If you prefer manual setup:
-
-```bash
-# Install framework
-uv pip install -e .
-
-# Install MCP dependencies
-uv pip install mcp fastmcp
-
-# Test the server
-uv run python -m framework.mcp.agent_builder_server
-```
-
-### Using with MCP Clients
-
-To use the agent builder with Claude Desktop or other MCP clients, add this to your MCP client configuration:
-
-```json
-{
-  "mcpServers": {
-    "agent-builder": {
-      "command": "python",
-      "args": ["-m", "framework.mcp.agent_builder_server"],
-      "cwd": "/path/to/goal-agent"
-    }
-  }
-}
-```
-
-The MCP server provides tools for:
- Creating agent building sessions
- Defining goals with success criteria
- Adding nodes (llm_generate, llm_tool_use, router, function)
- Connecting nodes with edges
- Validating and exporting agent graphs
- Testing nodes and full agent graphs
+See the [Getting Started Guide](../docs/getting-started.md) for building agents.

-Aden Hive Framework: A goal-driven agent runtime optimized for Builder observability.

-The runtime is designed around DECISIONS, not just actions. Every significant

- What it was trying to do (intent)
- What options it considered
- What it chose and why
- What happened as a result
- Whether that was good or bad (evaluated post-hoc)
-
-This gives the Builder LLM the information it needs to improve agent behavior.

-## Testing Framework
-
-The framework includes a Goal-Based Testing system (Goal → Agent → Eval):
- Generate tests from Goal success_criteria and constraints
- Mandatory user approval before tests are stored
- Parallel test execution with error categorization
- Debug tools with fix suggestions
-
-See `framework.testing` for details.
