-1. Register the hive-tools MCP server:
+1. Check for existing sessions:
 
 ```

+**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.
 
-**START by asking the user to help shape the goal:**
+### 2a: Fast Discovery (3-8 Turns)
 
-> I've set up the build environment and discovered [N] available tools. Let's define the goal for your agent together.
->
-> To get started, can you help me understand:
->
-> 1. **What should this agent accomplish?** (the core purpose)
-> 2. **How will we know it succeeded?** (what does "done" look like)
-> 3. **Are there any hard constraints?** (things it must never do, quality bars, etc.)
+**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.
 
-**WAIT for the user to respond.** Use their input to draft:
+**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].

+| **Forever-alive (loop)** | `[]` (empty) | Agent stays alive for continuous interaction (research assistant, personal assistant, monitoring) |
+
+**Forever-alive pattern:** The deep_research_agent example uses `terminal_nodes=[]`. Every leaf node has edges that loop back to earlier nodes, creating a perpetual session. The agent only stops when the user explicitly exits. This is the preferred pattern for interactive, multi-turn agents.
+
+**Key design rules for forever-alive graphs:**
+- Every node must have at least one outgoing edge (no dead ends)
+- Client-facing nodes block for user input — these are the natural "pause points"
+- The user controls when to stop, not the graph
+- Sessions accumulate memory across loops — plan for conversation compaction
+- Use `conversation_mode="continuous"` to preserve conversation history across node transitions
+- `max_iterations` should be set high (e.g., 100) since the agent is designed to run indefinitely
+- The agent will NOT enter a "completed" execution state — this is intentional, not a bug
+
+**Ask the user** which lifecycle pattern fits their agent. Default to forever-alive for interactive agents, linear for batch/one-shot tasks.
+
 **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.

+## REFERENCE: Graph Lifecycle & Conversation Memory
+
+### Terminal vs Forever-Alive Graphs
+
+Agents have two lifecycle patterns:
+
+**Linear (terminal) graphs** have `terminal_nodes=["last-node"]`. Execution ends when the terminal node completes. The session enters a "completed" state. Use for batch processing, one-shot generation, and fire-and-forget tasks.
+
+**Forever-alive graphs** have `terminal_nodes=[]` (empty). Every node has at least one outgoing edge — the graph loops indefinitely. The session **never enters a "completed" state** — this is intentional. The agent stays alive until the user explicitly exits. Use for interactive assistants, research tools, and any agent where the user drives the conversation.
+
+The deep_research_agent example demonstrates this: `report` loops back to either `research` (dig deeper) or `intake` (new topic). The agent is a persistent, interactive assistant.
+
+### Continuous Conversation Mode
+
+When `conversation_mode="continuous"` is set on the GraphSpec, the framework preserves a **single conversation thread** across all node transitions:
+
+**What the framework does automatically:**
+- **Inherits conversation**: Same message history carries forward to the next node
+- **Composes layered system prompts**: Identity (agent-level) + Narrative (auto-generated state summary) + Focus (per-node instructions)
+- **Inserts transition markers**: At each node boundary, a "State of the World" message showing completed phases, current memory, and available data files
+- **Accumulates tools**: Once a tool becomes available, it stays available in subsequent nodes
+- **Compacts opportunistically**: At phase transitions, old tool results are pruned to stay within token budget
+
+**What this means for agent builders:**
+- Nodes don't need to re-explain context — the conversation carries it forward
+- Output keys from earlier nodes are available in memory for edge conditions and later nodes
+- For forever-alive agents, conversation memory persists across the entire session lifetime
+- Plan for compaction: very long sessions will have older tool results summarized automatically
+
+**When to use continuous mode:**
+- Interactive agents with client-facing nodes (always)
+- Multi-phase workflows where context matters across phases
+- Forever-alive agents that loop indefinitely
+
+**When NOT to use continuous mode:**
+- Embarrassingly parallel fan-out nodes (each branch should be independent)
+- Stateless utility agents that process items independently
+
+---
+
+## 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 |
+|----------|---------------------|-------------|
+| Persistent background daemons (no user) | Forever-alive graphs need a user at client-facing nodes; no autonomous background polling without user | External scheduler triggering agent runs |
+| 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 | Traditional code 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. **Using tools that don't exist** - Always check `mcp__agent-builder__list_mcp_tools()` first
-2. **Wrong entry_points format** - Must be `{"start": "node-id"}`, NOT a set or list
-3. **Skipping validation** - Always validate nodes and graph before proceeding
-4. **Not waiting for approval** - Always ask user before major steps
-5. **Displaying this file** - Execute the steps, don't show documentation
-6. **Too many thin nodes** - Prefer fewer, richer nodes (4 nodes > 8 nodes)
-7. **Missing STEP 1/STEP 2 in client-facing prompts** - Client-facing nodes need explicit phases to prevent premature set_output
-8. **Forgetting nullable_output_keys** - Mark input_keys that only arrive on certain edges (e.g., feedback) as nullable on the receiving node
-9. **Adding framework gating for LLM behavior** - Fix prompts or use judges, not ad-hoc code
-10. **Writing code before user approves the graph** - Always get approval on goal, nodes, and graph BEFORE writing any agent code
-11. **Wrong mcp_servers.json format** - Use flat format (no `"mcpServers"` wrapper), and `cwd` must be `"../../tools"` not `"tools"`
+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", ...]`
+14. **Assuming all agents need terminal nodes** - Interactive agents often work best with `terminal_nodes=[]` (forever-alive pattern). The agent never enters "completed" state — this is intentional. Only batch/one-shot agents need terminal nodes
+15. **Creating dead-end nodes in forever-alive graphs** - Every node must have at least one outgoing edge. A node with no outgoing edges will cause execution to end unexpectedly, breaking the forever-alive loop
+16. **Not using continuous conversation mode for interactive agents** - Multi-phase interactive agents should use `conversation_mode="continuous"` to preserve context across node transitions. Without it, each node starts with a blank conversation and loses all prior context

-## Step 2: Get Constraint Test Guidelines
+**Goal:** "Rigorous Interactive Research" — find 5+ diverse sources, cite every claim, produce a complete report.
 
-During the Goal stage (or early Eval), get test guidelines for constraints:
+---
+
+## Phase 1: Generate Tests
+
+### Read the goal
 
 ```python
-result = generate_constraint_tests(
-    goal_id="youtube-research",
-    goal_json='<goal JSON above>',
-    agent_path="exports/youtube-research"
-)
+Read(file_path="exports/deep_research_agent/agent.py")
+# Extract: goal_id="rigorous-interactive-research"
+# success_criteria: source-diversity (>=5), citation-coverage (100%), report-completeness (90%)
+# constraints: no-hallucination, source-attribution
 ```
 
-**The result contains guidelines (not generated tests):**
-- `output_file`: Where to write tests
-- `file_header`: Imports and fixtures to use
-- `test_template`: Format for test functions
-- `constraints_formatted`: The constraints to test
-- `test_guidelines`: Rules for writing tests
-
-## Step 3: Write Constraint Tests
-
-Using the guidelines, write tests directly with the Write tool:
-
-```python
-# Write constraint tests using the provided file_header and guidelines
-Write(
-    file_path="exports/youtube-research/tests/test_constraints.py",
-    content='''
-"""Constraint tests for youtube-research agent."""

-        assert video.safe_for_work is True
-        assert video.age_restricted is False
-'''
-)
-```
-
-## Step 4: Get Success Criteria Test Guidelines
-
-After the agent is built, get success criteria test guidelines:
+### Get test guidelines
 
 ```python

 ```
 
-## Step 5: Write Success Criteria Tests
-
-Using the guidelines, write success criteria tests:

-## Step 7: Debug the Failed Test
+---
+
+## Phase 3: Analyze (Iteration 1)
+
+### Debug the first failure
 
 ```python

-    test_name="test_find_videos_no_results_graceful",
-    agent_path="exports/youtube-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(

+    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",

+    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."'
 )
 ```
 
-**Debug Output:**
+---
 
+## 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",

-## Step 8: Iterate Based on Category
+Source diversity now passes. Citation coverage still fails.
 
-Since this is an **IMPLEMENTATION_ERROR**, we:
+---
 
-1. **Don't restart** the Goal → Agent → Eval flow
-2. **Fix the agent** using hive-create skill:
-   - Modify `filter_node` to handle null results
-3. **Re-run Eval** (tests only)
-
-### Fix in hive-create:
+## Phase 3: Analyze (Iteration 2)
 
 ```python
-# Update the filter_node to handle null
-add_node(
-    node_id="filter_node",
-    name="Filter Node",

+    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",

At the end, include a References section listing all sources with their URLs. Every claim must be traceable to a specific source."'
 )
 ```
 
-### Re-export and re-test:
+---
+
+## 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
-# Re-export the fixed agent
-export_graph(path="exports/youtube-research")
-
-# Re-run tests

 ## Summary
 
-1. **Got guidelines** for constraint tests during Goal stage
-2. **Wrote** constraint tests using Write tool
-3. **Got guidelines** for success criteria tests during Eval stage
-4. **Wrote** success criteria tests using Write tool
-5. **Ran** tests in parallel
-6. **Debugged** the one failure
-7. **Categorized** as IMPLEMENTATION_ERROR
-8. **Fixed** the agent (not the goal)
-9. **Re-ran** Eval only (didn't restart full flow)
-10. **Passed** all tests
+| 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) |
 
-The agent is now validated and ready for production use.
+**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, determine what the user needs and invoke the appropriate skill NOW:
-- **User wants to build an agent** → Invoke `/hive-create` immediately
-- **User wants to test an agent** → Invoke `/hive-test` immediately
-- **User wants to learn concepts** → Invoke `/hive-concepts` immediately
-- **User wants patterns/optimization** → Invoke `/hive-patterns` immediately
-- **User wants to set up credentials** → Invoke `/hive-credentials` immediately
-- **Unclear what user needs** → Ask the user (do NOT explore the codebase to figure it out)
+When this skill is loaded, **ALWAYS use the AskUserQuestion tool** to present options:

+```
+Use AskUserQuestion with these options:

+# Repository Guidelines
+
+Shared agent instructions for this workspace.
+
+## Deprecations
+
+- **TUI is deprecated.** The terminal UI (`hive tui`) is no longer maintained. Use the browser-based interface (`hive open`) instead.
+
+## 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.

-All notable changes to this project will be documented in this file.
+**Release Date:** February 18, 2026
+**Tag:** v0.5.1

+## The Hive Gets a Brain
 
-## [Unreleased]
+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.
 
-### Added
-- Initial project structure
-- React frontend (honeycomb) with Vite and TypeScript
-- Node.js backend (hive) with Express and TypeScript
-- Docker Compose configuration for local development
-- Configuration system via `config.yaml`
-- GitHub Actions CI/CD workflows
-- Comprehensive documentation
+---
 
-### Changed
-- N/A
+## Highlights
 
-### Deprecated
-- N/A
+### Hive Coder -- The Agent That Builds Agents
 
-### Removed
-- N/A
+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
 
-### Fixed
-- tools: Fixed web_scrape tool attempting to parse non-HTML content (PDF, JSON) as HTML (#487)
+# Or escalate from any running agent (TUI)
+Ctrl+E  # or /coder in chat
+```
 
-### Security
-- N/A
+The Coder ships with:
 
-## [0.1.0] - 2025-01-13
+- **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()`
 
-### Added
-- Initial release
+### Multi-Graph Agent Runtime
 
-[Unreleased]: https://github.com/adenhq/hive/compare/v0.1.0...HEAD
-[0.1.0]: https://github.com/adenhq/hive/releases/tag/v0.1.0
+`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)
+
+---
+
+## Bug Fixes
+
+- Flush WIP accumulator outputs on cancel/failure so edge conditions see correct values on resume
+- Stall detection state preserved across resume (no more resets on checkpoint restore)
+- Skip client-facing blocking for event-triggered executions (timer/webhook)
+- Executor retry override scoped to actual EventLoopNode instances only
+- Add `_awaiting_input` flag to EventLoopNode to prevent input injection race conditions
+- Fix TUI streaming display (tokens no longer appear one-per-line)
+- Fix `_return_from_escalation` crash when ChatRepl widgets not yet mounted
+- Fix tools registration problems for Google Docs credentials (@RichardTang-Aden)
+- Fix email agent version conflicts (@RichardTang-Aden)
+- Fix coder tool timeouts (120s for tests, 300s cap for commands)
+
+## 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.
+- **Vulnerability Assessment** -- Expanded prompts with more detailed assessment instructions. (@bryanadenhq)
+
+---
+
+## 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`)
+- **`NodeSpec.function` field removed** -- `FunctionNode` is deleted; use event_loop nodes with tools instead.
+
+---
+
+## Community Contributors
+
+A huge thank you to everyone who contributed to this release:
+
+- **Richard Tang** (@RichardTang-Aden) -- Interactive credential setup, pre-start confirmation, email agent consolidation, tool registration fixes, lint and formatting
+- **Pravin Mishra** (@mishrapravin114) -- Discord integration with 4 MCP tools
+- **Jeet Karia** (@JeetKaria06) -- Exa Search API integration with 4 AI-powered search tools
+- **Shivam Shahi** (@shivamshahi07) -- Razorpay payment processing integration
+- **Siddharth Varshney** (@Siddharth2624) -- Utils module exports
+- **@haliaeetusvocifer** -- Google Docs integration with OAuth support
+- **Bryan** (@bryanadenhq) -- PDF selection, inbox agent fixes, Job Hunter and Vulnerability Assessment updates
+- **@paarths-collab** -- Documentation improvements
+
+---
+
+## Upgrading
+
+```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
+```
+
+---
+
+## What's Next
+
+- **Agent-to-agent communication** -- one agent's output triggers another agent's entry point
+- **Cost visibility** -- detailed runtime log of LLM costs per node and per session
+- **Persistent webhook subscriptions** -- survive agent restarts without re-registering
+- **Remote agent deployment** -- run agents as long-lived services with HTTP APIs

 ## Overview
 
-Build 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.

 ## Quick Start
 
-## Prerequisites
+### Prerequisites
 
 - Python 3.11+ for agent development
-- Claude Code or Cursor for utilizing agent skills
+- An LLM provider that powers the agents
 
 > **Note for Windows Users:** It is strongly recommended to use **WSL (Windows Subsystem for Linux)** or **Git Bash** to run this framework. Some core automation scripts may not execute correctly in standard Command Prompt or PowerShell.
 
 ### Installation
 
+> **Note**
+> Hive uses a `uv` workspace layout and is not installed with `pip install`.
+> Running `pip install -e .` from the repository root will create a placeholder package and Hive will not function correctly.
+> Please use the quickstart script below to set up the environment.
+
 ```bash
 # Clone the repository
-git clone https://github.com/adenhq/hive.git
+git clone https://github.com/aden-hive/hive.git
 cd hive
 
+
 # Run quickstart setup
 ./quickstart.sh

 ## 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](docs/key_concepts/goals_outcome.md), and the system builds itself**—delivering an outcome-driven, [adaptive](docs/key_concepts/evolution.md) experience with an easy-to-use set of tools and integrations.

 ## Frequently Asked Questions (FAQ)
 
-**Q: Does Hive depend on LangChain or other agent frameworks?**
-
-No. Hive is built from the ground up with no dependencies on LangChain, CrewAI, or other agent frameworks. The framework is designed to be lean and flexible, generating agent graphs dynamically rather than relying on predefined components.

 **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: Does Hive collect data from users?**
-
-Hive collects telemetry data for monitoring and observability purposes, including token usage, latency metrics, and cost tracking. Content capture (prompts and responses) is configurable and stored with team-scoped data isolation. All data stays within your infrastructure when self-hosted.
-
-**Q: What deployment options does Hive support?**
-
-Hive supports self-hosted deployments via Python packages. See the [Environment Setup Guide](docs/environment-setup.md) for installation instructions. Cloud deployment options and Kubernetes-ready configurations are on the roadmap.
-
 **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?**
-
-Aden's [adaptation loop](docs/key_concepts/evolution.md) 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](docs/key_concepts/goals_outcome.md), 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.

+perf: reduce subprocess spawning in quickstart scripts (#4427)
+
+## Problem
+Windows process creation (CreateProcess) is 10-100x slower than Linux fork/exec.
+The quickstart scripts were spawning 4+ separate `uv run python -c "import X"` 
+processes to verify imports, adding ~600ms overhead on Windows.
+
+## Solution
+Consolidated all import checks into a single batch script that checks multiple 
+modules in one subprocess call, reducing spawn overhead by ~75%.
+
+## Changes
+- **New**: `scripts/check_requirements.py` - Batched import checker
+- **New**: `scripts/test_check_requirements.py` - Test suite  
+- **New**: `scripts/benchmark_quickstart.ps1` - Performance benchmark tool
+- **Modified**: `quickstart.ps1` - Updated import verification (2 sections)
+- **Modified**: `quickstart.sh` - Updated import verification
+
+## Performance Impact
+**Benchmark results on Windows:**
+- Before: ~19.8 seconds for import checks
+- After: ~4.9 seconds for import checks
+- **Improvement: 14.9 seconds saved (75.2% faster)**
+
+## Testing
+- ✅ All functional tests pass (`scripts/test_check_requirements.py`)
+- ✅ Quickstart scripts work correctly on Windows
+- ✅ Error handling verified (invalid imports reported correctly)
+- ✅ Performance benchmark confirms 75%+ improvement
+
+Fixes #4427

+"""Credential Tester agent — verify credentials via live API calls.
+
+Supports both Aden OAuth2-synced accounts AND locally-stored API key accounts.
+Aden accounts use account="alias" routing; local accounts inject the key into
+the session environment so tools read it without an account= parameter.
+
+When loaded via AgentRunner.load() (TUI picker, ``hive run``), the module-level
+``nodes`` / ``edges`` variables provide a static graph.  The TUI detects
+``requires_account_selection`` and shows an account picker *before* starting
+the agent.  ``configure_for_account()`` then scopes the node's tools to the
+selected provider.
+
+When used directly (``CredentialTesterAgent``), the graph is built dynamically
+after the user picks an account programmatically.

+
+# Core Mandates
+
+- **Read before writing.** NEVER write code from assumptions. Read \
+reference agents and templates first. Read every file before editing.
+- **Conventions first.** Follow existing project patterns exactly. \
+Analyze imports, structure, and style in reference agents.
+- **Verify assumptions.** Never assume a class, import, or pattern \
+exists. Read actual source to confirm. Search if unsure.
+- **Discover tools dynamically.** NEVER reference tools from static \
+docs. Always run list_agent_tools() to see what actually exists.
+- **Professional objectivity.** If a use case is a poor fit for the \
+framework, say so. Technical accuracy over validation.
+- **Concise.** No emojis. No preambles. No postambles. Substance only.
+- **Self-verify.** After writing code, run validation and tests. Fix \
+errors yourself. Don't declare success until validation passes.
+
+# Tools
+
+## File I/O
+- read_file(path, offset?, limit?) — read with line numbers
+- write_file(path, content) — create/overwrite, auto-mkdir
+- edit_file(path, old_text, new_text, replace_all?) — fuzzy-match edit
+- list_directory(path, recursive?) — list contents
+- search_files(pattern, path?, include?) — regex search
+- run_command(command, cwd?, timeout?) — shell execution
+- undo_changes(path?) — restore from git snapshot
+
+## Meta-Agent
+- list_agent_tools(server_config_path?, output_schema?, group?) — discover \
+available tools grouped by category. output_schema: "simple" (default) or \
+"full" (includes input_schema). group: "all" (default) or a prefix like \
+"gmail". Call FIRST before designing.
+- validate_agent_tools(agent_path) — validate that all tools declared \
+in an agent's nodes actually exist. Call after building.
+- list_agents() — list all agent packages in exports/ with session counts
+- list_agent_sessions(agent_name, status?, limit?) — list sessions
+- get_agent_session_state(agent_name, session_id) — full session state
+- get_agent_session_memory(agent_name, session_id, key?) — memory data
+- list_agent_checkpoints(agent_name, session_id) — list checkpoints
+- get_agent_checkpoint(agent_name, session_id, checkpoint_id?) — load checkpoint
+- run_agent_tests(agent_name, test_types?, fail_fast?) — run pytest with parsing
+
+# Meta-Agent Capabilities
+
+You are not just a file writer. You have deep integration with the \
+Hive framework:
+
+## Tool Discovery (MANDATORY before designing)
+Before designing any agent, run list_agent_tools() to discover all \
+available tools. ONLY use tools from this list in your node definitions. \
+NEVER guess or fabricate tool names from memory.
+
+  list_agent_tools()                                    # names + descriptions
+  list_agent_tools(output_schema="full")                # include input_schema
+  list_agent_tools(group="gmail")                       # only gmail_* tools
+  list_agent_tools("exports/{agent_name}/mcp_servers.json")  # specific agent
+
+## Agent Awareness
+Run list_agents() to see what agents already exist. Read their code \
+for patterns:
+  read_file("exports/{name}/agent.py")
+  read_file("exports/{name}/nodes/__init__.py")
+
+## Post-Build Testing
+After writing agent code, validate structurally AND run tests:
+  run_command("python -c 'from {name} import default_agent; \\
+    print(default_agent.validate())'")
+  run_agent_tests("{name}")
+
+## Debugging Built Agents
+When a user says "my agent is failing" or "debug this agent":
+1. list_agent_sessions("{agent_name}") — find the session
+2. get_agent_session_state("{agent_name}", "{session_id}") — see status
+3. get_agent_session_memory("{agent_name}", "{session_id}") — inspect data
+4. list_agent_checkpoints / get_agent_checkpoint — trace execution
+
+# Agent Building Workflow
+
+You operate in a continuous loop. The user describes what they want, \
+you build it. No rigid phases — use judgment. But the general flow is:
+
+## 1. Understand & Qualify (3-5 turns)
+
+This is ONE conversation, not two phases. Discovery and qualification \
+happen together. Surface problems as you find them, not in a batch.
+
+**Before your first response**, silently run list_agent_tools() and \
+consult the **Framework Reference** appendix. Know what's possible \
+before you speak.
+
+### How to respond to the user's first message
+
+**Listen like an architect.** While they talk, hear the structure:
+- **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?
+- **The pain**: What about today is broken, slow, or missing?
+
+| 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 |
+
+**Use domain knowledge aggressively.** If they say "research agent," \
+you already know it involves search, summarization, source tracking, \
+iteration. Don't ask about each — use them as defaults and let their \
+specifics override. Merge your general knowledge with their specifics: \
+60-80% right before you ask a single question.
+
+### Play back a model WITH qualification baked in
+
+Don't separate "here's what I understood" from "here's what might be \
+a problem." Weave them together. Your playback should sound like:
+
+"Here's how I'm picturing this: [concrete proposed solution]. \
+The framework handles [X and Y] well for this. [One concern: Z tool \
+doesn't exist, so we'd use W instead / Z would need real-time which \
+isn't a fit, but we could do polling]. For MVP I'd focus on \
+[highest-value thing]. Before I start — [1-2 questions]."
+
+If there's a deal-breaker, lead with it: "Before I go further — \
+this needs [X] which the framework can't do because [Y]. We could \
+[workaround] or reconsider the approach. What do you think?"
+
+**Surface problems immediately. Don't save them for a formal review.**
+
+### Ask only what you CANNOT infer
+
+Every question must earn its place by preventing a costly wrong turn, \
+unlocking a shortcut, or surfacing a dealbreaker.
+
+Good questions: "Who's the primary user?", "Is this replacing \
+something or net new?", "Does this integrate with anything?"
+
+Bad questions (DON'T ask): "What should happen on error?", "Should \
+it have search?", "What tools should I use?" — these are your job.
+
+### Conversation flow
+
+| Turn | Who | What |
+|------|-----|------|
+| 1 | User | Describes what they need |
+| 2 | You | Play back model with concerns baked in. 1-2 questions max. |
+| 3 | User | Corrects, confirms, or adds detail |
+| 4 | You | Adjust model, confirm scope, move to design |
+
+### Anti-patterns
+
+| Don't | Do instead |
+|-------|------------|
+| Open with a list of questions | Open with what you understood |
+| Separate "assessment" dump | Weave concerns into your playback |
+| Good/Bad/Ugly formal section | Mention issues naturally in context |
+| Ask about every edge case | Smart defaults, flag in summary |
+| 10+ turn discovery | 3-5 turns, then start building |
+| Wait for certainty | Start at 80% confidence, iterate |
+| Ask what tech/tools to use | Decide, disclose, move on |
+
+## 3. Design
+
+Design the agent architecture:
+- Goal: id, name, description, 3-5 success criteria, 2-4 constraints
+- Nodes: **2-4 nodes MAXIMUM** (see rules below)
+- Edges: on_success for linear, conditional for routing
+- Lifecycle: ALWAYS forever-alive (`terminal_nodes=[]`) unless the user \
+explicitly requests a one-shot/batch agent. Forever-alive agents loop \
+continuously — the user exits by closing the TUI. This is the standard \
+pattern for all interactive agents.
+
+### Node Design Rules
+
+Each node boundary serializes outputs to shared memory \
+and DESTROYS all in-context information (tool results, reasoning, history). \
+Use as many nodes as the use case requires, but don't create nodes without \
+tools — merge them into nodes that do real work.
+
+**MERGE nodes when:**
+- Node has NO tools (pure LLM reasoning) → merge into predecessor/successor
+- Node sets only 1 trivial output → collapse into predecessor
+- Multiple consecutive autonomous nodes → combine into one rich node
+- A "report" or "summary" node → merge into the client-facing node
+- A "confirm" or "schedule" node that calls no external service → remove
+
+**SEPARATE nodes only when:**
+- Client-facing vs autonomous (different interaction models)
+- Fundamentally different tool sets
+- Fan-out parallelism (parallel branches MUST be separate)
+
+**Typical patterns (queen manages intake — NO client-facing intake node):**
+- 2 nodes: `process (autonomous) → review (client-facing) → process`
+- 1 node: `process (autonomous)` — simplest; queen handles all interaction
+- WRONG: 7 nodes where half have no tools and just do LLM reasoning
+- WRONG: Intake node that asks the user for requirements — the queen does intake
+
+Read reference agents before designing:
+  list_agents()
+  read_file("exports/deep_research_agent/agent.py")
+  read_file("exports/deep_research_agent/nodes/__init__.py")
+
+Present the design to the user. Lead with a large ASCII graph inside \
+a code block so it renders in monospace. Make it visually prominent — \
+use box-drawing characters and clear flow arrows:
+
+```
+┌─────────────────────────┐
+│  process (autonomous)    │
+│  in:  user_request       │
+│  tools: web_search,      │
+│         save_data        │
+└────────────┬────────────┘
+             │ on_success
+             ▼
+┌─────────────────────────┐
+│  review (client-facing)  │
+│  tools: set_output       │
+└────────────┬────────────┘
+             │ on_success
+             └──────► back to process
+```
+
+The queen owns intake: she gathers user requirements, then calls \
+`run_agent_with_input(task)` with a structured task description. \
+When building the agent, design the entry node's `input_keys` to \
+match what the queen will provide at run time. No client-facing \
+intake node in the worker.
+
+Follow the graph with a brief summary of each node's purpose. \
+Get user approval before implementing.
+
+## 4. Implement
+
+Consult the **File Templates** and **Anti-Patterns** appendices below.
+
+Write files in order:
+1. mkdir -p exports/{name}/nodes exports/{name}/tests
+2. config.py — RuntimeConfig + AgentMetadata
+3. nodes/__init__.py — NodeSpec definitions with system prompts
+4. agent.py — Goal, edges, graph, agent class
+5. __init__.py — package exports
+6. __main__.py — CLI with click
+7. mcp_servers.json — tool server config
+8. tests/ — fixtures
+
+### Critical Rules
+
+**Imports** (must match exactly — only import what you use):
+```python
+from framework.graph import (
+    NodeSpec, EdgeSpec, EdgeCondition,
+    Goal, SuccessCriterion, Constraint,
+)
+from framework.graph.edge import GraphSpec
+from framework.graph.executor import ExecutionResult
+from framework.graph.checkpoint_config import CheckpointConfig
+from framework.llm import LiteLLMProvider
+from framework.runner.tool_registry import ToolRegistry
+from framework.runtime.agent_runtime import (
+    AgentRuntime, create_agent_runtime,
+)
+from framework.runtime.execution_stream import EntryPointSpec
+```
+For agents with async entry points (timers, webhooks, events), also add:
+```python
+from framework.graph.edge import GraphSpec, AsyncEntryPointSpec
+from framework.runtime.agent_runtime import (
+    AgentRuntime, AgentRuntimeConfig, create_agent_runtime,
+)
+```
+NEVER `from core.framework...` — PYTHONPATH includes core/.
+
+**__init__.py MUST re-export ALL module-level variables** \
+(THIS IS THE #1 SOURCE OF AGENT LOAD FAILURES):
+The runner imports the package (__init__.py), NOT agent.py. It reads \
+goal, nodes, edges, entry_node, entry_points, pause_nodes, \
+terminal_nodes, conversation_mode, identity_prompt, loop_config via \
+getattr(). If ANY are missing from __init__.py, they silently default \
+to None or {} — causing "must define goal, nodes, edges" or "node X \
+is unreachable" errors. The __init__.py MUST import and re-export \
+ALL of these from .agent:
+```python
+from .agent import (
+    MyAgent, default_agent, goal, nodes, edges,
+    entry_node, entry_points, pause_nodes, terminal_nodes,
+    conversation_mode, identity_prompt, loop_config,
+)
+```
+
+**entry_points**: `{"start": "first-node-id"}`
+The first node should be an autonomous processing node (NOT a \
+client-facing intake). For agents with multiple entry points, \
+add them: `{"start": "process", "reminder": "check"}`
+
+**conversation_mode** — ONLY two valid values:
+- `"continuous"` — recommended for interactive agents (context carries \
+across node transitions)
+- Omit entirely — for isolated per-node conversations
+NEVER use: "client_facing", "interactive", "adaptive", or any other \
+value. These DO NOT EXIST.
+
+**loop_config** — ONLY three valid keys:
+```python
+loop_config = {
+    "max_iterations": 100,
+    "max_tool_calls_per_turn": 30,
+    "max_history_tokens": 32000,
+}
+```
+NEVER add: "strategy", "mode", "timeout", or other keys.
+
+**mcp_servers.json**:
+```json
+{
+  "hive-tools": {
+    "transport": "stdio",
+    "command": "uv",
+    "args": ["run", "python", "mcp_server.py", "--stdio"],
+    "cwd": "../../tools"
+  }
+}
+```
+NO "mcpServers" wrapper. cwd "../../tools". command "uv".
+
+**Storage**: `Path.home() / ".hive" / "agents" / "{name}"`
+
+**Client-facing system prompts** (review/approval nodes only, NOT intake) \
+— STEP 1/STEP 2 pattern:
+```
+STEP 1 — Present to user (text only, NO tool calls):
+[instructions]
+
+STEP 2 — After user responds, call set_output:
+[set_output calls]
+```
+The queen manages intake. Workers should NOT have a client-facing node \
+that asks for requirements. Use client_facing=True only for review or \
+approval checkpoints mid-execution.
+
+**Autonomous system prompts** — set_output in SEPARATE turn.
+
+**Tools** — NEVER fabricate tool names. Common hallucinations: \
+csv_read, csv_write, csv_append, file_upload, database_query. \
+If list_agent_tools() shows these don't exist, use alternatives \
+(e.g. save_data/load_data for data persistence).
+
+**Node rules**:
+- **NO intake nodes.** The queen owns intake. She defines the entry \
+node's input_keys at build time and fills them via \
+`run_agent_with_input(task)` at run time.
+- Don't abuse nodes without tools — merge them into a node that does work.
+- A node with 0 tools is NOT a real node — merge it.
+- node_type "event_loop" for all regular graph nodes. Use "gcu" ONLY for
+  browser automation subagents (see GCU appendix). GCU nodes MUST be in a
+  parent node's sub_agents list, NEVER connected via edges, and NEVER used
+  as entry/terminal nodes.
+- max_node_visits default is 0 (unbounded) — correct for forever-alive. \
+Only set >0 in one-shot agents with bounded feedback loops.
+- Feedback inputs: nullable_output_keys
+- terminal_nodes=[] for forever-alive (the default)
+- Every node MUST have at least one outgoing edge (no dead ends)
+- Agents are forever-alive unless user explicitly asks for one-shot
+
+**Agent class**: CamelCase name, default_agent at module level. \
+Constructor takes `config=None`. Follow the exact pattern in \
+file_templates.md — do NOT invent constructor params like \
+`llm_provider` or `tool_registry`.
+
+**Module-level variables** (read by AgentRunner.load()):
+goal, nodes, edges, entry_node, entry_points, pause_nodes,
+terminal_nodes, conversation_mode, identity_prompt, loop_config
+
+For agents with async triggers, also export:
+async_entry_points, runtime_config
+
+**Async entry points** (timers, webhooks, events):
+When an agent needs scheduled tasks, webhook reactions, or event-driven \
+triggers, use `AsyncEntryPointSpec` (from framework.graph.edge) and \
+`AgentRuntimeConfig` (from framework.runtime.agent_runtime):
+- Timer (cron): `trigger_type="timer"`, \
+`trigger_config={"cron": "0 9 * * *"}` — standard 5-field cron expression \
+(e.g. `"0 9 * * MON-FRI"` weekdays 9am, `"*/30 * * * *"` every 30 min)
+- Timer (interval): `trigger_type="timer"`, \
+`trigger_config={"interval_minutes": 20, "run_immediately": False}`
+- Event (for webhooks): `trigger_type="event"`, \
+`trigger_config={"event_types": ["webhook_received"]}`
+- `isolation_level="shared"` so async runs can read primary session memory
+- `runtime_config = AgentRuntimeConfig(webhook_routes=[...])` for HTTP webhooks
+- Reference: `exports/gmail_inbox_guardian/agent.py`
+- Full docs: see **Framework Reference** appendix (Async Entry Points section)
+
+## 5. Verify
+
+Run FOUR validation steps after writing. All must pass:
+
+**Step A — Class validation** (checks graph structure):
+```
+run_command("python -c 'from {name} import default_agent; \\
+  print(default_agent.validate())'")
+```
+
+**Step B — Runner load test** (checks package export contract — \
+THIS IS THE SAME PATH THE TUI USES):
+```
+run_command("python -c 'from framework.runner.runner import \\
+  AgentRunner; r = AgentRunner.load(\"exports/{name}\"); \\
+  print(\"AgentRunner.load: OK\")'")
+```
+This catches missing __init__.py exports, bad conversation_mode, \
+invalid loop_config, and unreachable nodes. If Step A passes but \
+Step B fails, the problem is in __init__.py exports.
+
+**Step C — Tool validation** (checks that declared tools actually exist \
+in the agent's MCP servers — catches hallucinated tool names):
+```
+validate_agent_tools("exports/{name}")
+```
+If any tools are missing: fix the node definitions to use only tools \
+that exist. Run list_agent_tools() to see what's available.
+
+**Step D — Run tests:**
+```
+run_agent_tests("{name}")
+```
+
+If anything fails: read error, fix with edit_file, re-validate. Up to 3x.
+
+**CRITICAL: Testing forever-alive agents**
+Most agents use `terminal_nodes=[]` (forever-alive). This means \
+`runner.run()` NEVER returns — it hangs forever waiting for a \
+terminal node that doesn't exist. Agent tests MUST be structural:
+- Validate graph, node specs, edges, tools, prompts
+- Check goal/constraints/success criteria definitions
+- Test `AgentRunner.load()` succeeds (structural, no API key needed)
+- NEVER call `runner.run()` or `trigger_and_wait()` in tests for \
+forever-alive agents — they will hang and time out.
+When you restructure an agent (change nodes/edges), always update \
+the tests to match. Stale tests referencing old node names will fail.
+
+## 6. Present
+
+Show the user what you built: agent name, goal summary, graph (same \
+ASCII style as Design), files created, validation status. Offer to \
+revise or build another.

+
+## Operating Modes
+
+You operate in one of three modes. Your available tools change based on the \
+mode. The system notifies you when a mode change occurs.
+
+### BUILDING mode (default)
+You have full coding tools for building and modifying agents:
+- File I/O: read_file, write_file, edit_file, list_directory, search_files, \
+run_command, undo_changes
+- Meta-agent: list_agent_tools, validate_agent_tools, \
+list_agents, list_agent_sessions, get_agent_session_state, get_agent_session_memory, \
+list_agent_checkpoints, get_agent_checkpoint, run_agent_tests
+- load_built_agent(agent_path) — Load the agent and switch to STAGING mode
+- list_credentials(credential_id?) — List authorized credentials
+
+When you finish building an agent, call load_built_agent(path) to stage it.
+
+### STAGING mode (agent loaded, not yet running)
+The agent is loaded and ready to run. You can inspect it and launch it:
+- Read-only: read_file, list_directory, search_files, run_command
+- list_credentials(credential_id?) — Verify credentials are configured
+- get_worker_status() — Check the loaded worker
+- run_agent_with_input(task) — Start the worker and switch to RUNNING mode
+- stop_worker_and_edit() — Go back to BUILDING mode
+
+In STAGING mode you do NOT have write tools. If you need to modify the agent, \
+call stop_worker_and_edit() to go back to BUILDING mode.
+
+### RUNNING mode (worker is executing)
+The worker is running. You have monitoring and lifecycle tools:
+- Read-only: read_file, list_directory, search_files, run_command
+- get_worker_status() — Check worker status (idle, running, waiting)
+- inject_worker_message(content) — Send a message to the running worker
+- get_worker_health_summary() — Read the latest health data
+- notify_operator(ticket_id, analysis, urgency) — Alert the user (use sparingly)
+- stop_worker() — Stop the worker and return to STAGING mode, then ask the user what to do next
+- stop_worker_and_edit() — Stop the worker and switch back to BUILDING mode
+
+In RUNNING mode you do NOT have write tools or agent construction tools. \
+If you need to modify the agent, call stop_worker_and_edit() to switch back \
+to BUILDING mode. To stop the worker and ask the user what to do next, call \
+stop_worker() to return to STAGING mode.
+
+### Mode transitions
+- load_built_agent(path) → switches to STAGING mode
+- run_agent_with_input(task) → starts worker, switches to RUNNING mode
+- stop_worker() → stops worker, switches to STAGING mode (ask user: re-run or edit?)
+- stop_worker_and_edit() → stops worker (if running), switches to BUILDING mode

+# Behavior
+
+## CRITICAL RULE — ask_user tool
+
+Every response that ends with a question, a prompt, or expects user \
+input MUST finish with a call to ask_user(prompt, options). This is \
+NON-NEGOTIABLE. The system CANNOT detect that you are waiting for \
+input unless you call ask_user. You MUST call ask_user as the LAST \
+action in your response.
+
+NEVER end a response with a question in text without calling ask_user. \
+NEVER rely on the user seeing your text and replying — call ask_user.
+
+Always provide 2-4 short options that cover the most likely answers. \
+The user can always type a custom response.
+
+Examples:
+- ask_user("What do you need?",
+  ["Build a new agent", "Run the loaded worker", "Help with code"])
+- ask_user("Which pattern?",
+  ["Simple 2-node", "Rich with feedback", "Custom"])
+- ask_user("Ready to proceed?",
+  ["Yes, go ahead", "Let me change something"])
+
+## Greeting and identity
+
+When the user greets you or asks what you can do, respond concisely \
+(under 10 lines). DO NOT list internal processes. Focus on:
+1. Direct capabilities: coding, agent building & debugging.
+2. What the loaded worker does (one sentence from Worker Profile). \
+If no worker is loaded, say so.
+3. THEN call ask_user to prompt them — do NOT just write text.
+
+## Direct coding
+You can do any coding task directly — reading files, writing code, running \
+commands, building agents, debugging. For quick tasks, do them yourself.
+
+## Worker delegation
+The worker is a specialized agent (see Worker Profile at the end of this \
+prompt). It can ONLY do what its goal and tools allow.
+
+**Decision rule — read the Worker Profile first:**
+- The user's request directly matches the worker's goal → use \
+run_agent_with_input(task) (if in staging) or load then run (if in building)
+- Anything else → do it yourself. Do NOT reframe user requests into \
+subtasks to justify delegation.
+- Building, modifying, or configuring agents is ALWAYS your job. Never \
+delegate agent construction to the worker, even as a "research" subtask.
+
+## When the user says "run", "execute", or "start" (without specifics)
+
+The loaded worker is described in the Worker Profile below. You MUST \
+ask the user what task or input they want using ask_user — do NOT \
+invent a task, do NOT call list_agents() or list directories. \
+The worker is already loaded. Just ask for the specific input the \
+worker needs (e.g., a research topic, a target domain, a job description). \
+NEVER call run_agent_with_input until the user has provided their input.
+
+If NO worker is loaded, say so and offer to build one.
+
+## When in staging mode (agent loaded, not running):
+- Tell the user the agent is loaded and ready.
+- For tasks matching the worker's goal: ALWAYS ask the user for their \
+specific input BEFORE calling run_agent_with_input(task). NEVER make up \
+or assume what the user wants. Use ask_user to collect the task details \
+(e.g., topic, target, requirements). Once you have the user's answer, \
+compose a structured task description from their input and call \
+run_agent_with_input(task). The worker has no intake node — it receives \
+your task and starts processing.
+- If the user wants to modify the agent, call stop_worker_and_edit().
+
+## When idle (worker not running):
+- Greet the user. Mention what the worker can do in one sentence.
+- For tasks matching the worker's goal, use run_agent_with_input(task) \
+(if in staging) or load the agent first (if in building).
+- For everything else, do it directly.
+
+## When the user clicks Run (external event notification)
+When you receive an event that the user clicked Run:
+- If the worker started successfully, briefly acknowledge it — do NOT \
+repeat the full status. The user can see the graph is running.
+- If the worker failed to start (credential or structural error), \
+explain the problem clearly and help fix it. For credential errors, \
+guide the user to set up the missing credentials. For structural \
+issues, offer to fix the agent graph directly.
+
+## When worker is running — GO SILENT
+
+Once you call start_worker(), your job is DONE. Do NOT call ask_user, \
+do NOT call get_worker_status(), do NOT emit any text. Just stop. \
+The worker owns the conversation now — it has its own client-facing \
+nodes that talk to the user directly.
+
+**After start_worker, your ENTIRE response should be ONE short \
+confirmation sentence with NO tool calls.** Example: \
+"Started the vulnerability assessment." — that's it. No ask_user, \
+no get_worker_status, no follow-up questions.
+
+You only wake up again when:
+- The user explicitly addresses you (not answering a worker question)
+- A worker question is forwarded to you for relay
+- An escalation ticket arrives from the judge
+- The worker finishes
+
+If the user explicitly asks about progress, call get_worker_status() \
+ONCE and report. Do NOT poll or check proactively.
+
+For escalation tickets: low/transient → acknowledge silently. \
+High/critical → notify the user with a brief analysis.
+
+## When the worker asks the user a question:
+- The user's answer is routed to you with context: \
+[Worker asked: "...", Options: ...] User answered: "...".
+- If the user is answering the worker's question normally, relay it \
+using inject_worker_message(answer_text). Then go silent again.
+- If the user is rejecting the approach, asking to stop, or giving \
+you an instruction, handle it yourself — do NOT relay.
+
+## Showing or describing the loaded worker
+
+When the user asks to "show the graph", "describe the agent", or \
+"re-generate the graph", read the Worker Profile and present the \
+worker's current architecture as an ASCII diagram. Use the processing \
+stages, tools, and edges from the loaded worker. Do NOT enter the \
+agent building workflow — you are describing what already exists, not \
+building something new.
+
+## Modifying the loaded worker
+
+When the user asks to change, modify, or update the loaded worker \
+(e.g., "change the report node", "add a node", "delete node X"):
+
+1. Call stop_worker_and_edit() — this stops the worker and gives you \
+coding tools (switches to BUILDING mode).
+2. Use the **Path** from the Worker Profile to locate the agent files.
+3. Read the relevant files (nodes/__init__.py, agent.py, etc.).
+4. Make the requested changes using edit_file / write_file.
+5. Run validation (default_agent.validate(), AgentRunner.load(), \
+validate_agent_tools()).
+6. **Reload the modified worker**: call load_built_agent("{path}") \
+so the changes take effect immediately (switches to STAGING mode). \
+Then call run_agent_with_input(task) to restart execution.
+
+Do NOT skip step 6 — without reloading, the user will still be \
+interacting with the old version.
+"""
+
+_queen_phase_7 = """
+## 7. Load into Session
+
+After building and verifying, load the agent into the current session:
+  load_built_agent("exports/{name}")
+This switches to STAGING mode — the user sees the agent's graph and \
+the tab name updates. Then call run_agent_with_input(task) to start it. \

+# Common Mistakes When Building Hive Agents
+
+## Critical Errors
+
+1. **Using tools that don't exist** — Always verify tools are available in the hive-tools MCP server before assigning them to nodes. Never guess tool names.
+
+2. **Wrong entry_points format** — MUST be `{"start": "first-node-id"}`. NOT a set, NOT `{node_id: [keys]}`.
+
+3. **Wrong mcp_servers.json format** — Flat dict (no `"mcpServers"` wrapper). `cwd` must be `"../../tools"`. `command` must be `"uv"` with args `["run", "python", ...]`.
+
+4. **Missing STEP 1/STEP 2 in client-facing prompts** — Without explicit phases, the LLM calls set_output before the user responds. Always use the pattern.
+
+5. **Forgetting nullable_output_keys** — When a node receives inputs from multiple edges and some inputs only arrive on certain edges (e.g., feedback), mark those as nullable. Without this, the executor blocks waiting for a value that will never arrive.
+
+6. **Creating dead-end nodes in forever-alive graphs** — Every node must have at least one outgoing edge. A node with no outgoing edges ends the execution, breaking the loop.
+
+7. **Setting max_node_visits to a non-zero value in forever-alive agents** — The framework default is `max_node_visits=0` (unbounded). Setting it to any positive value (e.g., 1) means the node stops executing after that many visits, silently breaking the forever-alive loop. Only set `max_node_visits > 0` in one-shot agents with feedback loops that need bounded retries.
+
+7. **Missing module-level exports in `__init__.py`** — The runner loads agents via `importlib.import_module(package_name)`, which imports `__init__.py`. It then reads `goal`, `nodes`, `edges`, `entry_node`, `entry_points`, `pause_nodes`, `terminal_nodes`, `conversation_mode`, `identity_prompt`, `loop_config` via `getattr()`. If ANY of these are missing from `__init__.py`, they default to `None` or `{}` — causing "must define goal, nodes, edges" errors or "node X is unreachable" validation failures. **ALL module-level variables from agent.py must be re-exported in `__init__.py`.**
+
+## Value Errors
+
+8. **Invalid `conversation_mode` value** — Only two valid values: `"continuous"` (recommended for interactive agents) or omit entirely (for isolated per-node conversations). Values like `"client_facing"`, `"interactive"`, `"adaptive"` do NOT exist and will cause runtime errors.
+
+9. **Invalid `loop_config` keys** — Only three valid keys: `max_iterations` (int), `max_tool_calls_per_turn` (int), `max_history_tokens` (int). Keys like `"strategy"`, `"mode"`, `"timeout"` are NOT valid and are silently ignored or cause errors.
+
+10. **Fabricating tools that don't exist** — Never guess tool names. Always verify via `list_agent_tools()` before designing and `validate_agent_tools()` after building. Common hallucinations: `csv_read`, `csv_write`, `csv_append`, `file_upload`, `database_query`, `bulk_fetch_emails`. If a required tool doesn't exist, redesign the agent to use tools that DO exist (e.g., `save_data`/`load_data` for data persistence).
+
+## Design Errors
+
+11. **Too many thin nodes** — Hard limit: **2-4 nodes** for most agents. Each node boundary serializes outputs to shared memory and loses all in-context information (tool results, intermediate reasoning, conversation history). A node with 0 tools that just does LLM reasoning is NOT a real node — merge it into its predecessor or successor.
+
+**Merge when:**
+- Node has NO tools — pure LLM reasoning belongs in the node that produces or consumes its data
+- Node sets only 1 trivial output (e.g., `set_output("done", "true")`) — collapse into predecessor
+- Multiple consecutive autonomous nodes with same/similar tools — combine into one
+- A "report" or "summary" node that just presents analysis — merge into the client-facing node
+- A "schedule" or "confirm" node that doesn't actually schedule anything — remove entirely
+
+**Keep separate when:**
+- Client-facing vs autonomous — different interaction models require separate nodes
+- Fundamentally different tool sets (e.g., web search vs file I/O)
+- Fan-out parallelism — parallel branches MUST be separate nodes
+
+**Bad example** (7 nodes — WAY too many):
+```
+profile_setup → daily_intake → update_tracker → analyze_progress → generate_plan → schedule_reminders → report
+```
+`analyze_progress` has no tools. `schedule_reminders` just sets one boolean. `report` just presents analysis. `update_tracker` and `generate_plan` are sequential autonomous work.
+
+**Good example** (2 nodes):
+```
+process (autonomous: track + analyze + plan) → review (client-facing) → process (loop back)
+```
+The queen handles intake (gathering requirements from the user) and passes the task via `run_agent_with_input(task)`. One autonomous node handles ALL backend work (CSV update, analysis, plan generation) with tools and context preserved. One client-facing node handles review/approval when needed.
+
+12. **Adding framework gating for LLM behavior** — Don't add output rollback, premature rejection, or interaction protocol injection. Fix with better prompts or custom judges.
+
+13. **Not using continuous conversation mode** — Interactive agents should use `conversation_mode="continuous"`. Without it, each node starts with blank context.
+
+14. **Adding terminal nodes by default** — ALL agents should use `terminal_nodes=[]` (forever-alive) unless the user explicitly requests a one-shot/batch agent. Forever-alive is the standard pattern. Every node must have at least one outgoing edge. Dead-end nodes break the loop.
+
+15. **Calling set_output in same turn as tool calls** — Instruct the LLM to call set_output in a SEPARATE turn from real tool calls.
+
+## File Template Errors
+
+16. **Wrong import paths** — Use `from framework.graph import ...`, NOT `from core.framework.graph import ...`. The PYTHONPATH includes `core/`.
+
+17. **Missing storage path** — Agent class must set `self._storage_path = Path.home() / ".hive" / "agents" / "agent_name"`.
+
+18. **Missing mcp_servers.json** — Without this, the agent has no tools at runtime.
+
+19. **Bare `python` command in mcp_servers.json** — Use `"command": "uv"` with args `["run", "python", ...]`.
+
+## Testing Errors
+
+20. **Using `runner.run()` on forever-alive agents** — `runner.run()` calls `trigger_and_wait()` which blocks until the graph reaches a terminal node. Forever-alive agents have `terminal_nodes=[]`, so **`runner.run()` hangs forever**. This is the #1 cause of stuck test suites.
+
+**For forever-alive agents, write structural tests instead:**
+- Validate graph structure (nodes, edges, entry points)
+- Verify node specs (tools, prompts, client-facing flag)
+- Check goal/constraints/success criteria definitions
+- Test that `AgentRunner.load()` succeeds (structural, no API key needed)
+
+**What NOT to do:**
+```python
+# WRONG — hangs forever on forever-alive agents
+result = await runner.run({"topic": "quantum computing"})
+```
+
+**Correct pattern for structure tests:**
+```python
+def test_research_has_web_tools(self):
+    assert "web_search" in research_node.tools
+
+def test_research_routes_back_to_interact(self):
+    edges_to_interact = [e for e in edges if e.source == "research" and e.target == "interact"]
+    assert edges_to_interact
+```
+
+21. **Stale tests after agent restructuring** — When you change an agent's node count or names (e.g., 4 nodes → 2 nodes), the tests MUST be updated too. Tests referencing old node names (e.g., `"review"`, `"report"`) will fail or hang. Always check that test assertions match the current `nodes/__init__.py`.
+
+22. **Running full integration tests without API keys** — Structural tests (validate, import) work without keys. Full integration tests need `ANTHROPIC_API_KEY`. Use `pytest.skip()` in the runner fixture when `_setup()` fails due to missing credentials.
+
+23. **Forgetting sys.path setup in conftest.py** — Tests need `exports/` and `core/` on sys.path.
+
+24. **Not using auto_responder for client-facing nodes** — Tests with client-facing nodes hang without an auto-responder that injects input. But note: even WITH auto_responder, forever-alive agents still hang because the graph never terminates. Auto-responder only helps for agents with terminal nodes.
+
+25. **Manually wiring browser tools on event_loop nodes** — If the agent needs browser automation, use `node_type="gcu"` which auto-includes all browser tools and prepends best-practices guidance. Do NOT manually list browser tool names on event_loop nodes — they may not exist in the MCP server or may be incomplete. See the GCU Guide appendix.
+
+26. **Using GCU nodes as regular graph nodes** — GCU nodes (`node_type="gcu"`) are exclusively subagents. They must ONLY appear in a parent node's `sub_agents=["gcu-node-id"]` list and be invoked via `delegate_to_sub_agent()`. They must NEVER be connected via edges, used as entry nodes, or used as terminal nodes. If a GCU node appears as an edge source or target, the graph will fail pre-load validation.
+
+27. **Adding a client-facing intake node to worker agents** — The queen owns intake. She defines the entry node's `input_keys` at build time and fills them via `run_agent_with_input(task)` at run time. Worker agents should start with an autonomous processing node, NOT a client-facing intake node that asks the user for requirements. Client-facing nodes in workers are for mid-execution review/approval only.

+## agent.py — Async Entry Points Variant
+
+When an agent needs timers, webhooks, or event-driven triggers, add
+`async_entry_points` and optionally `runtime_config` as module-level variables.
+These are IN ADDITION to the standard variables above.
+
+```python
+# Additional imports for async entry points
+from framework.graph.edge import GraphSpec, AsyncEntryPointSpec
+from framework.runtime.agent_runtime import (
+    AgentRuntime, AgentRuntimeConfig, create_agent_runtime,
+)
+
+# ... (goal, nodes, edges, entry_node, entry_points, etc. as above) ...
+
+# Async entry points — event-driven triggers
+async_entry_points = [
+    # Timer with cron: daily at 9am
+    AsyncEntryPointSpec(
+        id="daily-check",
+        name="Daily Check",
+        entry_node="process-node",
+        trigger_type="timer",
+        trigger_config={"cron": "0 9 * * *"},
+        isolation_level="shared",
+        max_concurrent=1,
+    ),
+    # Timer with fixed interval: every 20 minutes
+    AsyncEntryPointSpec(
+        id="scheduled-check",
+        name="Scheduled Check",
+        entry_node="process-node",
+        trigger_type="timer",
+        trigger_config={"interval_minutes": 20, "run_immediately": False},
+        isolation_level="shared",
+        max_concurrent=1,
+    ),
+    # Event: reacts to webhook events
+    AsyncEntryPointSpec(
+        id="webhook-event",
+        name="Webhook Event Handler",
+        entry_node="process-node",
+        trigger_type="event",
+        trigger_config={"event_types": ["webhook_received"]},
+        isolation_level="shared",
+        max_concurrent=10,
+    ),
+]
+
+# Webhook server config (only needed if using webhooks)
+runtime_config = AgentRuntimeConfig(
+    webhook_host="127.0.0.1",
+    webhook_port=8080,
+    webhook_routes=[
+        {
+            "source_id": "my-source",
+            "path": "/webhooks/my-source",
+            "methods": ["POST"],
+        },
+    ],
+)
+```
+
+**Key rules for async entry points:**
+- `async_entry_points` is a list of `AsyncEntryPointSpec` (NOT `EntryPointSpec`)
+- `runtime_config` is `AgentRuntimeConfig` (NOT `RuntimeConfig` from config.py)
+- Valid trigger_types: `timer`, `event`, `webhook`, `manual`, `api`
+- Valid isolation_levels: `isolated`, `shared`, `synchronized`
+- Timer trigger_config (cron): `{"cron": "0 9 * * *"}` — standard 5-field cron expression
+- Timer trigger_config (interval): `{"interval_minutes": float, "run_immediately": bool}`
+- Event trigger_config: `{"event_types": ["webhook_received"], "filter_stream": "...", "filter_node": "..."}`
+- Use `isolation_level="shared"` for async entry points that need to read
+  the primary session's memory (e.g., user-configured rules)
+- The `_build_graph()` method passes `async_entry_points` to GraphSpec
+- Reference: `exports/gmail_inbox_guardian/agent.py`
+
+## __init__.py
+
+**CRITICAL:** The runner imports the package (`__init__.py`) and reads ALL module-level
+variables via `getattr()`. Every variable defined in `agent.py` that the runner needs
+MUST be re-exported here. Missing exports cause silent failures (variables default to
+`None` or `{}`), leading to "must define goal, nodes, edges" errors or graph validation
+failures like "node X is unreachable".

+# Hive Agent Framework — Condensed Reference
+
+## Architecture
+
+Agents are Python packages in `exports/`:
+```
+exports/my_agent/
+├── __init__.py          # MUST re-export ALL module-level vars from agent.py
+├── __main__.py          # CLI (run, tui, info, validate, shell)
+├── agent.py             # Graph construction (goal, edges, agent class)

+├── nodes/__init__.py    # Node definitions (NodeSpec)

+└── tests/               # pytest tests
+```
+
+## Agent Loading Contract
+
+`AgentRunner.load()` imports the package (`__init__.py`) and reads these
+module-level variables via `getattr()`:
+
+| Variable | Required | Default if missing | Consequence |
+|----------|----------|--------------------|-------------|
+| `goal` | YES | `None` | **FATAL** — "must define goal, nodes, edges" |
+| `nodes` | YES | `None` | **FATAL** — same error |
+| `edges` | YES | `None` | **FATAL** — same error |
+| `entry_node` | no | `nodes[0].id` | Probably wrong node |
+| `entry_points` | no | `{}` | **Nodes unreachable** — validation fails |
+| `terminal_nodes` | no | `[]` | OK for forever-alive |
+| `pause_nodes` | no | `[]` | OK |
+| `conversation_mode` | no | not passed | Isolated mode (no context carryover) |
+| `identity_prompt` | no | not passed | No agent-level identity |
+| `loop_config` | no | `{}` | No iteration limits |
+| `async_entry_points` | no | `[]` | No async triggers (timers, webhooks, events) |
+| `runtime_config` | no | `None` | No webhook server |
+
+**CRITICAL:** `__init__.py` MUST import and re-export ALL of these from
+`agent.py`. Missing exports silently fall back to defaults, causing
+hard-to-debug failures.
+
+**Why `default_agent.validate()` is NOT sufficient:**
+`validate()` checks the agent CLASS's internal graph (self.nodes, self.edges).
+These are always correct because the constructor references agent.py's module
+vars directly. But `AgentRunner.load()` reads from the PACKAGE (`__init__.py`),
+not the class. So `validate()` passes while `AgentRunner.load()` fails.
+Always test with `AgentRunner.load("exports/{name}")` — this is the same
+code path the TUI and `hive run` use.
+
+## Goal
+
+Defines success criteria and constraints:
+```python
+goal = Goal(
+    id="kebab-case-id",
+    name="Display Name",
+    description="What the agent does",
+    success_criteria=[
+        SuccessCriterion(id="sc-id", description="...", metric="...", target="...", weight=0.25),
+    ],
+    constraints=[
+        Constraint(id="c-id", description="...", constraint_type="hard", category="quality"),
+    ],
+)
+```
+- 3-5 success criteria, weights sum to 1.0
+- 1-5 constraints (hard/soft, categories: quality, accuracy, interaction, functional)
+
+## NodeSpec Fields
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| id | str | required | kebab-case identifier |
+| name | str | required | Display name |
+| description | str | required | What the node does |
+| node_type | str | required | `"event_loop"` or `"gcu"` (browser automation — see GCU Guide appendix) |
+| input_keys | list[str] | required | Memory keys this node reads |
+| output_keys | list[str] | required | Memory keys this node writes via set_output |
+| system_prompt | str | "" | LLM instructions |
+| tools | list[str] | [] | Tool names from MCP servers |
+| client_facing | bool | False | If True, streams to user and blocks for input |
+| nullable_output_keys | list[str] | [] | Keys that may remain unset |
+| max_node_visits | int | 0 | 0=unlimited (default); >1 for one-shot feedback loops |
+| max_retries | int | 3 | Retries on failure |
+| success_criteria | str | "" | Natural language for judge evaluation |
+
+## EdgeSpec Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| id | str | kebab-case identifier |
+| source | str | Source node ID |
+| target | str | Target node ID |
+| condition | EdgeCondition | ON_SUCCESS, ON_FAILURE, ALWAYS, CONDITIONAL |
+| condition_expr | str | Python expression evaluated against memory (for CONDITIONAL) |
+| priority | int | Positive=forward (evaluated first), negative=feedback (loop-back) |
+
+## Key Patterns
+
+### STEP 1/STEP 2 (Client-Facing Nodes)
+```
+**STEP 1 — Respond to the user (text only, NO tool calls):**
+[Present information, ask questions]
+
+**STEP 2 — After the user responds, call set_output:**
+- set_output("key", "value based on user response")
+```
+This prevents premature set_output before user interaction.
+
+### Fewer, Richer Nodes (CRITICAL)
+
+**Hard limit: 2-4 nodes for most agents.** Never exceed 5 unless the user
+explicitly requests a complex multi-phase pipeline.
+
+Each node boundary serializes outputs to shared memory and **destroys** all
+in-context information: tool call results, intermediate reasoning, conversation
+history. A research node that searches, fetches, and analyzes in ONE node keeps
+all source material in its conversation context. Split across 3 nodes, each
+downstream node only sees the serialized summary string.
+
+**Decision framework — merge unless ANY of these apply:**
+1. **Client-facing boundary** — Autonomous and client-facing work MUST be
+   separate nodes (different interaction models)
+2. **Disjoint tool sets** — If tools are fundamentally different (e.g., web
+   search vs database), separate nodes make sense
+3. **Parallel execution** — Fan-out branches must be separate nodes
+
+**Red flags that you have too many nodes:**
+- A node with 0 tools (pure LLM reasoning) → merge into predecessor/successor
+- A node that sets only 1 trivial output → collapse into predecessor
+- Multiple consecutive autonomous nodes → combine into one rich node
+- A "report" node that presents analysis → merge into the client-facing node
+- A "confirm" or "schedule" node that doesn't call any external service → remove
+
+**Typical agent structure (2 nodes):**
+```
+process (autonomous) ←→ review (client-facing)
+```
+The queen owns intake — she gathers requirements from the user, then
+passes structured input via `run_agent_with_input(task)`. When building
+the agent, design the entry node's `input_keys` to match what the queen
+will provide at run time. Worker agents should NOT have a client-facing
+intake node. Client-facing nodes are for mid-execution review/approval only.
+
+For simpler agents, just 1 autonomous node:
+```
+process (autonomous) — loops back to itself
+```
+
+### nullable_output_keys
+For inputs that only arrive on certain edges:
+```python
+research_node = NodeSpec(
+    input_keys=["brief", "feedback"],
+    nullable_output_keys=["feedback"],  # Only present on feedback edge
+    max_node_visits=3,
+)
+```
+
+### Mutually Exclusive Outputs
+For routing decisions:
+```python
+review_node = NodeSpec(
+    output_keys=["approved", "feedback"],
+    nullable_output_keys=["approved", "feedback"],  # Node sets one or the other
+)
+```
+
+### Forever-Alive Pattern
+`terminal_nodes=[]` — every node has outgoing edges, graph loops until user exits.
+Use `conversation_mode="continuous"` to preserve context across transitions.
+
+### set_output
+- Synthetic tool injected by framework
+- Call separately from real tool calls (separate turn)
+- `set_output("key", "value")` stores to shared memory
+
+## Edge Conditions
+
+| Condition | When |
+|-----------|------|
+| ON_SUCCESS | Node completed successfully |
+| ON_FAILURE | Node failed |
+| ALWAYS | Unconditional |
+| CONDITIONAL | condition_expr evaluates to True against memory |
+
+condition_expr examples:
+- `"needs_more_research == True"`
+- `"str(next_action).lower() == 'new_agent'"`
+- `"feedback is not None"`
+
+## Graph Lifecycle
+
+| Pattern | terminal_nodes | When |
+|---------|---------------|------|
+| **Forever-alive** | `[]` | **DEFAULT for all agents** |
+| Linear | `["last-node"]` | Only if user explicitly requests one-shot/batch |
+
+**Forever-alive is the default.** Always use `terminal_nodes=[]`.
+The framework default for `max_node_visits` is 0 (unbounded), so
+nodes work correctly in forever-alive loops without explicit override.
+Only set `max_node_visits > 0` in one-shot agents with feedback loops.
+Every node must have at least one outgoing edge — no dead ends. The
+user exits by closing the TUI. Only use terminal nodes if the user
+explicitly asks for a batch/one-shot agent that runs once and exits.
+
+## Continuous Conversation Mode
+
+`conversation_mode` has ONLY two valid states:
+- `"continuous"` — recommended for interactive agents
+- Omit entirely — isolated per-node conversations (each node starts fresh)
+
+**INVALID values** (do NOT use): `"client_facing"`, `"interactive"`,
+`"adaptive"`, `"shared"`. These do not exist in the framework.
+
+When `conversation_mode="continuous"`:
+- Same conversation thread carries across node transitions
+- Layered system prompts: identity (agent-level) + narrative + focus (per-node)
+- Transition markers inserted at boundaries
+- Compaction happens opportunistically at phase transitions
+
+## loop_config
+
+Only three valid keys:
+```python
+loop_config = {
+    "max_iterations": 100,          # Max LLM turns per node visit
+    "max_tool_calls_per_turn": 20,  # Max tool calls per LLM response
+    "max_history_tokens": 32000,    # Triggers conversation compaction
+}
+```
+**INVALID keys** (do NOT use): `"strategy"`, `"mode"`, `"timeout"`,
+`"temperature"`. These are silently ignored or cause errors.
+
+## Data Tools (Spillover)
+
+For large data that exceeds context:
+- `save_data(filename, data)` — Write to session data dir
+- `load_data(filename, offset, limit)` — Read with pagination
+- `list_data_files()` — List files
+- `serve_file_to_user(filename, label)` — Clickable file:// URI
+
+`data_dir` is auto-injected by framework — LLM never sees it.
+
+## Fan-Out / Fan-In
+
+Multiple ON_SUCCESS edges from same source → parallel execution via asyncio.gather().
+- Parallel nodes must have disjoint output_keys
+- Only one branch may have client_facing nodes
+- Fan-in node gets all outputs in shared memory
+
+## Judge System
+
+- **Implicit** (default): ACCEPTs when LLM finishes with no tool calls and all required outputs set
+- **SchemaJudge**: Validates against Pydantic model
+- **Custom**: Implement `evaluate(context) -> JudgeVerdict`
+
+Judge is the SOLE acceptance mechanism — no ad-hoc framework gating.
+
+## Async Entry Points (Webhooks, Timers, Events)
+
+For agents that need to react to external events (incoming emails, scheduled
+tasks, API calls), use `AsyncEntryPointSpec` and optionally `AgentRuntimeConfig`.
+
+### Imports
+```python
+from framework.graph.edge import GraphSpec, AsyncEntryPointSpec
+from framework.runtime.agent_runtime import AgentRuntime, AgentRuntimeConfig, create_agent_runtime
+```
+Note: `AsyncEntryPointSpec` is in `framework.graph.edge` (the graph/declarative layer).
+`AgentRuntimeConfig` is in `framework.runtime.agent_runtime` (the runtime layer).
+
+### AsyncEntryPointSpec Fields
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| id | str | required | Unique identifier |
+| name | str | required | Human-readable name |
+| entry_node | str | required | Node ID to start execution from |
+| trigger_type | str | `"manual"` | `webhook`, `api`, `timer`, `event`, `manual` |
+| trigger_config | dict | `{}` | Trigger-specific config (see below) |
+| isolation_level | str | `"shared"` | `isolated`, `shared`, `synchronized` |
+| priority | int | `0` | Execution priority (higher = more priority) |
+| max_concurrent | int | `10` | Max concurrent executions |
+
+### Trigger Types
+
+**timer** — Fires on a schedule. Two modes: cron expressions or fixed interval.
+
+Cron (preferred for precise scheduling):
+```python
+AsyncEntryPointSpec(
+    id="daily-digest",
+    name="Daily Digest",
+    entry_node="check-node",
+    trigger_type="timer",
+    trigger_config={"cron": "0 9 * * *"},  # daily at 9am
+    isolation_level="shared",
+    max_concurrent=1,
+)
+```
+- `cron` (str) — standard cron expression (5 fields: min hour dom month dow)
+- Examples: `"0 9 * * *"` (daily 9am), `"0 9 * * MON-FRI"` (weekdays 9am), `"*/30 * * * *"` (every 30 min)
+
+Fixed interval (simpler, for polling-style tasks):
+```python
+AsyncEntryPointSpec(
+    id="scheduled-check",
+    name="Scheduled Check",
+    entry_node="check-node",
+    trigger_type="timer",
+    trigger_config={"interval_minutes": 20, "run_immediately": False},
+    isolation_level="shared",
+    max_concurrent=1,
+)
+```
+- `interval_minutes` (float) — how often to fire
+- `run_immediately` (bool, default False) — fire once on startup
+
+**event** — Subscribes to EventBus (e.g., webhook events):
+```python
+AsyncEntryPointSpec(
+    id="email-event",
+    name="Email Event Handler",
+    entry_node="process-emails",
+    trigger_type="event",
+    trigger_config={"event_types": ["webhook_received"]},
+    isolation_level="shared",
+    max_concurrent=10,
+)
+```
+- `event_types` (list[str]) — EventType values to subscribe to
+- `filter_stream` (str, optional) — only receive from this stream
+- `filter_node` (str, optional) — only receive from this node
+
+**webhook** — HTTP endpoint (requires AgentRuntimeConfig):
+The webhook server publishes `WEBHOOK_RECEIVED` events on the EventBus.
+An `event` trigger type with `event_types: ["webhook_received"]` subscribes
+to those events. The flow is:
+```
+HTTP POST /webhooks/gmail → WebhookServer → EventBus (WEBHOOK_RECEIVED)
+  → event entry point → triggers graph execution from entry_node
+```
+
+**manual** — Triggered programmatically via `runtime.trigger()`.
+
+### Isolation Levels
+
+| Level | Meaning |
+|-------|---------|
+| `isolated` | Private state per execution |
+| `shared` | Eventual consistency — async executions can read primary session memory |
+| `synchronized` | Shared with write locks (use when ordering matters) |
+
+For most async patterns, use `shared` — the async execution reads the primary
+session's memory (e.g., user-configured rules) and runs its own workflow.
+
+### AgentRuntimeConfig (for webhook servers)
+
+```python
+from framework.runtime.agent_runtime import AgentRuntimeConfig
+
+runtime_config = AgentRuntimeConfig(
+    webhook_host="127.0.0.1",
+    webhook_port=8080,
+    webhook_routes=[
+        {
+            "source_id": "gmail",
+            "path": "/webhooks/gmail",
+            "methods": ["POST"],
+            "secret": None,  # Optional HMAC-SHA256 secret
+        },
+    ],
+)
+```
+`runtime_config` is a module-level variable read by `AgentRunner.load()`.
+The runner passes it to `create_agent_runtime()`. On `runtime.start()`,
+if webhook_routes is non-empty, an embedded HTTP server starts.
+
+### Session Sharing
+
+Timer and event triggers automatically call `_get_primary_session_state()`
+before execution. This finds the active user-facing session and provides
+its memory to the async execution, filtered to only the async entry node's
+`input_keys`. This means the async flow can read user-configured values
+(like rules, preferences) without needing separate configuration.
+
+### Module-Level Variables
+
+Agents with async entry points must export two additional variables:
+```python
+# In agent.py:
+async_entry_points = [AsyncEntryPointSpec(...), ...]
+runtime_config = AgentRuntimeConfig(...)  # Only if using webhooks
+```
+
+Both must be re-exported from `__init__.py`:
+```python
+from .agent import (
+    ..., async_entry_points, runtime_config,
+)
+```
+
+### Reference Agent
+
+See `exports/gmail_inbox_guardian/agent.py` for a complete example with:
+- Primary client-facing node (user configures rules)
+- Timer-based scheduled inbox checks (every 20 min)
+- Webhook-triggered email event handling
+- Shared isolation for memory access across streams
+
+## Framework Capabilities
+
+**Works well:** Multi-turn conversations, HITL review, tool orchestration, structured outputs, parallel execution, context management, error recovery, session persistence.
+
+**Limitations:** LLM latency (2-10s/turn), context window limits (~128K), cost per run, rate limits, node boundaries lose context.
+
+**Not designed for:** Sub-second responses, millions of items, real-time streaming, guaranteed determinism, offline/air-gapped.
+
+## Tool Discovery
+
+Do NOT rely on a static tool list — it will be outdated. Always use
+`list_agent_tools()` to discover available tools, grouped by category.
+
+```
+list_agent_tools()                            # names + descriptions, all groups
+list_agent_tools(output_schema="full")        # include input_schema
+list_agent_tools(group="gmail")               # only gmail_* tools
+list_agent_tools("exports/my_agent/mcp_servers.json")  # specific agent's tools
+```
+
+After building, validate tools exist: `validate_agent_tools("exports/{name}")`
+
+Common tool categories (verify via list_agent_tools):
+- **Web**: search, scrape, PDF
+- **Data**: save/load/append/list data files, serve to user
+- **File**: view, write, replace, diff, list, grep
+- **Communication**: email, gmail, slack, telegram
+- **CRM**: hubspot, apollo, calcom
+- **GitHub**: stargazers, user profiles, repos
+- **Vision**: image analysis
+- **Time**: current time

+# GCU Browser Automation Guide
+
+## When to Use GCU Nodes
+
+Use `node_type="gcu"` when:
+- The user's workflow requires **navigating real websites** (scraping, form-filling, social media interaction, testing web UIs)
+- The task involves **dynamic/JS-rendered pages** that `web_scrape` cannot handle (SPAs, infinite scroll, login-gated content)
+- The agent needs to **interact with a website** — clicking, typing, scrolling, selecting, uploading files
+
+Do NOT use GCU for:
+- Static content that `web_scrape` handles fine
+- API-accessible data (use the API directly)
+- PDF/file processing
+- Anything that doesn't require a browser UI
+
+## What GCU Nodes Are
+
+- `node_type="gcu"` — a declarative enhancement over `event_loop`
+- Framework auto-prepends browser best-practices system prompt
+- Framework auto-includes all 31 browser tools from `gcu-tools` MCP server
+- Same underlying `EventLoopNode` class — no new imports needed
+- `tools=[]` is correct — tools are auto-populated at runtime
+
+## GCU Architecture Pattern  
+
+GCU nodes are **subagents** — invoked via `delegate_to_sub_agent()`, not connected via edges.
+
+- Primary nodes (`event_loop`, client-facing) orchestrate; GCU nodes do browser work
+- Parent node declares `sub_agents=["gcu-node-id"]` and calls `delegate_to_sub_agent(agent_id="gcu-node-id", task="...")`
+- GCU nodes set `max_node_visits=1` (single execution per delegation), `client_facing=False`
+- GCU nodes use `output_keys=["result"]` and return structured JSON via `set_output("result", ...)`
+
+## GCU Node Definition Template
+
+```python
+gcu_browser_node = NodeSpec(
+    id="gcu-browser-worker",
+    name="Browser Worker",
+    description="Browser subagent that does X.",
+    node_type="gcu",
+    client_facing=False,
+    max_node_visits=1,
+    input_keys=[],
+    output_keys=["result"],
+    tools=[],  # Auto-populated with all browser tools
+    system_prompt="""\
+You are a browser agent. Your job: [specific task].
+
+## Workflow
+1. browser_start (only if no browser is running yet)
+2. browser_open(url=TARGET_URL) — note the returned targetId
+3. browser_snapshot to read the page
+4. [task-specific steps]
+5. set_output("result", JSON)
+
+## Output format
+set_output("result", JSON) with:
+- [field]: [type and description]
+""",
+)
+```
+
+## Parent Node Template (orchestrating GCU subagents)
+
+```python
+orchestrator_node = NodeSpec(
+    id="orchestrator",
+    ...
+    node_type="event_loop",
+    sub_agents=["gcu-browser-worker"],
+    system_prompt="""\
+...
+delegate_to_sub_agent(
+    agent_id="gcu-browser-worker",
+    task="Navigate to [URL]. Do [specific task]. Return JSON with [fields]."
+)
+...
+""",
+    tools=[],  # Orchestrator doesn't need browser tools
+)
+```
+
+## mcp_servers.json with GCU
+
+```json
+{
+  "hive-tools": { ... },
+  "gcu-tools": {
+    "transport": "stdio",
+    "command": "uv",
+    "args": ["run", "python", "-m", "gcu.server", "--stdio"],
+    "cwd": "../../tools",
+    "description": "GCU tools for browser automation"
+  }
+}
+```
+
+Note: `gcu-tools` is auto-added if any node uses `node_type="gcu"`, but including it explicitly is fine.
+
+## GCU System Prompt Best Practices
+
+Key rules to bake into GCU node prompts:
+
+- Prefer `browser_snapshot` over `browser_get_text("body")` — compact accessibility tree vs 100KB+ raw HTML
+- Always `browser_wait` after navigation
+- Use large scroll amounts (~2000-5000) for lazy-loaded content
+- For spillover files, use `run_command` with grep, not `read_file`
+- If auth wall detected, report immediately — don't attempt login
+- Keep tool calls per turn ≤10
+- Tab isolation: when browser is already running, use `browser_open(background=true)` and pass `target_id` to every call
+
+## GCU Anti-Patterns
+
+- Using `browser_screenshot` to read text (use `browser_snapshot`)
+- Re-navigating after scrolling (resets scroll position)
+- Attempting login on auth walls
+- Forgetting `target_id` in multi-tab scenarios
+- Putting browser tools directly on `event_loop` nodes instead of using GCU subagent pattern
+- Making GCU nodes `client_facing=True` (they should be autonomous subagents)
