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

-You are a research agent. Given a research brief, find and analyze sources.
-
-If feedback is provided, this is a follow-up round — focus on the gaps identified.
-
-Work in phases:
-1. **Search**: Use web_search with 3-5 diverse queries covering different angles.
-   Prioritize authoritative sources (.edu, .gov, established publications).
-2. **Fetch**: Use web_scrape on the most promising URLs (aim for 5-8 sources).
-   Skip URLs that fail. Extract the substantive content.
-3. **Analyze**: Review what you've collected. Identify key findings, themes,
-   and any contradictions between sources.
-
-Important:
-- Work in batches of 3-4 tool calls at a time — never more than 10 per turn
-- After each batch, assess whether you have enough material
-- Prefer quality over quantity — 5 good sources beat 15 thin ones
-- Track which URL each finding comes from (you'll need citations later)
-- Call set_output for each key in a SEPARATE turn (not in the same turn as other tool calls)
-
-Context management:
-- Your tool results are automatically saved to files. After compaction, the file \
-references remain in the conversation — use load_data() to recover any content you need.
-- Use append_data('research_notes.md', ...) to maintain a running log of key findings \
-as you go. This survives compaction and helps the report node produce a detailed report.
-
-When done, use set_output (one key at a time, separate turns):
-- set_output("findings", "Structured summary: key findings with source URLs for each claim. \
-Include themes, contradictions, and confidence levels.")

-description: Set up and install credentials for an agent. Detects missing credentials from agent config, collects them from the user, and stores them securely in the local encrypted store at ~/.hive/credentials.
-license: Apache-2.0
-metadata:
-  author: hive

----
-
-# Setup Credentials
-
-Interactive credential setup for agents with multiple authentication options. Detects what's missing, offers auth method choices, validates with health checks, and stores credentials securely.
-
-## When to Use
-
-- Before running or testing an agent for the first time
-- When `AgentRunner.run()` fails with "missing required credentials"
-- When a user asks to configure credentials for an agent
-- After building a new agent that uses tools requiring API keys
-
-## Workflow
-
-### Step 1: Identify the Agent
-
-Determine which agent needs credentials. The user will either:
-
-- Name the agent directly (e.g., "set up credentials for hubspot-agent")
-- Have an agent directory open (check `exports/` for agent dirs)
-- Be working on an agent in the current session
-
-Locate the agent's directory under `exports/{agent_name}/`.
-
-### Step 2: Detect Missing Credentials
-
-Use the `check_missing_credentials` MCP tool to detect what the agent needs and what's already configured. This tool loads the agent, inspects its required tools and node types, maps them to credentials via `CREDENTIAL_SPECS`, and checks both the encrypted store and environment variables.
-
-```
-check_missing_credentials(agent_path="exports/{agent_name}")
-```
-
-The tool returns a JSON response:
-
-```json
-{
-  "agent": "exports/{agent_name}",
-  "missing": [
-    {
-      "credential_name": "brave_search",
-      "env_var": "BRAVE_SEARCH_API_KEY",
-      "description": "Brave Search API key for web search",
-      "help_url": "https://brave.com/search/api/",
-      "tools": ["web_search"]
-    }
-  ],
-  "available": [
-    {
-      "credential_name": "anthropic",
-      "env_var": "ANTHROPIC_API_KEY",
-      "source": "encrypted_store"
-    }
-  ],
-  "total_missing": 1,
-  "ready": false
-}
-```
-
-**If `ready` is true (nothing missing):** Report all credentials as configured and skip Steps 3-5. Example:
-
-```
-All required credentials are already configured:
-  ✓ anthropic (ANTHROPIC_API_KEY)
-  ✓ brave_search (BRAVE_SEARCH_API_KEY)
-Your agent is ready to run!
-```
-
-**If credentials are missing:** Continue to Step 3 with the `missing` list.
-
-### Step 3: Present Auth Options for Each Missing Credential
-
-For each missing credential, check what authentication methods are available:
-
-```python
-from aden_tools.credentials import CREDENTIAL_SPECS
-
-spec = CREDENTIAL_SPECS.get("hubspot")
-if spec:
-    # Determine available auth options
-    auth_options = []
-    if spec.aden_supported:
-        auth_options.append("aden")
-    if spec.direct_api_key_supported:
-        auth_options.append("direct")
-    auth_options.append("custom")  # Always available
-
-    # Get setup info
-    setup_info = {
-        "env_var": spec.env_var,
-        "description": spec.description,
-        "help_url": spec.help_url,
-        "api_key_instructions": spec.api_key_instructions,
-    }
-```
-
-Present the available options using AskUserQuestion:
-
-```
-Choose how to configure HUBSPOT_ACCESS_TOKEN:
-
-  1) Aden Platform (OAuth) (Recommended)
-     Secure OAuth2 flow via hive.adenhq.com
-     - Quick setup with automatic token refresh
-     - No need to manage API keys manually
-
-  2) Direct API Key
-     Enter your own API key manually
-     - Requires creating a HubSpot Private App
-     - Full control over scopes and permissions
-
-  3) Local Credential Setup (Advanced)
-     Programmatic configuration for CI/CD
-     - For automated deployments
-     - Requires manual API calls
-```
-
-### Step 4: Execute Auth Flow Based on User Choice
-
-#### Prerequisite: Ensure HIVE_CREDENTIAL_KEY Is Available
-
-Before storing any credentials, verify `HIVE_CREDENTIAL_KEY` is set (needed to encrypt/decrypt the local store). Check both the current session and shell config:
-
-```bash
-# Check current session
-printenv HIVE_CREDENTIAL_KEY > /dev/null 2>&1 && echo "session: set" || echo "session: not set"
-
-# Check shell config files
-for f in ~/.zshrc ~/.bashrc ~/.profile; do [ -f "$f" ] && grep -q 'HIVE_CREDENTIAL_KEY' "$f" && echo "$f"; done
-```
-
-- **In current session** — proceed to store credentials
-- **In shell config but NOT in current session** — run `source ~/.zshrc` (or `~/.bashrc`) first, then proceed
-- **Not set anywhere** — `EncryptedFileStorage` will auto-generate one. After storing, tell the user to persist it: `export HIVE_CREDENTIAL_KEY="{generated_key}"` in their shell profile
-
-> **⚠️ IMPORTANT: After adding `HIVE_CREDENTIAL_KEY` to the user's shell config, always display:**
-> ```
-> ⚠️  Environment variables were added to your shell config.
->     Open a NEW TERMINAL for them to take effect outside this session.
-> ```
-
-#### Option 1: Aden Platform (OAuth)
-
-This is the recommended flow for supported integrations (HubSpot, etc.).
-
-**How Aden OAuth Works:**
-
-The ADEN_API_KEY represents a user who has already completed OAuth authorization on Aden's platform. When users sign up and connect integrations on Aden, those OAuth tokens are stored server-side. Having an ADEN_API_KEY means:
-
-1. User has an Aden account
-2. User has already authorized integrations (HubSpot, etc.) via OAuth on Aden
-3. We just need to sync those credentials down to the local credential store
-
-**4.1a. Check for ADEN_API_KEY**
-
-```python
-import os
-aden_key = os.environ.get("ADEN_API_KEY")
-```
-
-If not set, guide user to get one from Aden (this is where they do OAuth):
-
-```python
-from aden_tools.credentials import open_browser, get_aden_setup_url
-
-# Open browser to Aden - user will sign up and connect integrations there
-url = get_aden_setup_url()  # https://hive.adenhq.com
-success, msg = open_browser(url)
-
-print("Please sign in to Aden and connect your integrations (HubSpot, etc.).")
-print("Once done, copy your API key and return here.")
-```
-
-Ask user to provide the ADEN_API_KEY they received.
-
-**4.1b. Save ADEN_API_KEY to Shell Config**
-
-With user approval, persist ADEN_API_KEY to their shell config:
-
-```python
-from aden_tools.credentials import (
-    detect_shell,
-    add_env_var_to_shell_config,
-    get_shell_source_command,
-)
-
-shell_type = detect_shell()  # 'bash', 'zsh', or 'unknown'
-
-# Ask user for approval before modifying shell config
-# If approved:
-success, config_path = add_env_var_to_shell_config(
-    "ADEN_API_KEY",
-    user_provided_key,
-    comment="Aden Platform (OAuth) API key"
-)
-
-if success:
-    source_cmd = get_shell_source_command()
-    print(f"Saved to {config_path}")
-    print(f"Run: {source_cmd}")
-```
-
-> **⚠️ IMPORTANT: After adding `ADEN_API_KEY` to the user's shell config, always display:**
-> ```
-> ⚠️  Environment variables were added to your shell config.
->     Open a NEW TERMINAL for them to take effect outside this session.
-> ```
-
-Also save to `~/.hive/configuration.json` for the framework:
-
-```python
-import json
-from pathlib import Path
-
-config_path = Path.home() / ".hive" / "configuration.json"
-config = json.loads(config_path.read_text()) if config_path.exists() else {}
-
-config["aden"] = {
-    "api_key_configured": True,
-    "api_url": "https://api.adenhq.com"
-}
-
-config_path.parent.mkdir(parents=True, exist_ok=True)
-config_path.write_text(json.dumps(config, indent=2))
-```
-
-**4.1c. Sync Credentials from Aden Server**
-
-Since the user has already authorized integrations on Aden, use the one-liner factory method:
-
-```python
-from core.framework.credentials import CredentialStore
-
-# This single call handles everything:
-# - Creates encrypted local storage at ~/.hive/credentials
-# - Configures Aden client from ADEN_API_KEY env var
-# - Syncs all credentials from Aden server automatically
-store = CredentialStore.with_aden_sync(
-    base_url="https://api.adenhq.com",
-    auto_sync=True,  # Syncs on creation
-)
-
-# Check what was synced
-synced = store.list_credentials()
-print(f"Synced credentials: {synced}")
-
-# If the required credential wasn't synced, the user hasn't authorized it on Aden yet
-if "hubspot" not in synced:
-    print("HubSpot not found in your Aden account.")
-    print("Please visit https://hive.adenhq.com to connect HubSpot, then try again.")
-```
-
-For more control over the sync process:
-
-```python
-from core.framework.credentials import CredentialStore
-from core.framework.credentials.aden import (
-    AdenCredentialClient,
-    AdenClientConfig,
-    AdenSyncProvider,
-)
-
-# Create client (API key loaded from ADEN_API_KEY env var)
-client = AdenCredentialClient(AdenClientConfig(
-    base_url="https://api.adenhq.com",
-))
-
-# Create provider and store
-provider = AdenSyncProvider(client=client)
-store = CredentialStore.with_encrypted_storage()
-
-# Manual sync
-synced_count = provider.sync_all(store)
-print(f"Synced {synced_count} credentials from Aden")
-```
-
-**4.1d. Run Health Check**
-
-```python
-from aden_tools.credentials import check_credential_health
-
-# Get the token from the store
-cred = store.get_credential("hubspot")
-token = cred.keys["access_token"].value.get_secret_value()
-
-result = check_credential_health("hubspot", token)
-if result.valid:
-    print("HubSpot credentials validated successfully!")
-else:
-    print(f"Validation failed: {result.message}")
-    # Offer to retry the OAuth flow
-```
-
-#### Option 2: Direct API Key
-
-For users who prefer manual API key management.
-
-**4.2a. Show Setup Instructions**
-
-```python
-from aden_tools.credentials import CREDENTIAL_SPECS
-
-spec = CREDENTIAL_SPECS.get("hubspot")
-if spec and spec.api_key_instructions:
-    print(spec.api_key_instructions)
-# Output:
-# To get a HubSpot Private App token:
-# 1. Go to HubSpot Settings > Integrations > Private Apps
-# 2. Click "Create a private app"
-# 3. Name your app (e.g., "Hive Agent")
-# ...
-
-if spec and spec.help_url:
-    print(f"More info: {spec.help_url}")
-```
-
-**4.2b. Collect API Key from User**
-
-Use AskUserQuestion to securely collect the API key:
-
-```
-Please provide your HubSpot access token:
-(This will be stored securely in ~/.hive/credentials)
-```
-
-**4.2c. Run Health Check Before Storing**
-
-```python
-from aden_tools.credentials import check_credential_health
-
-result = check_credential_health("hubspot", user_provided_token)
-if not result.valid:
-    print(f"Warning: {result.message}")
-    # Ask user if they want to:
-    # 1. Try a different token
-    # 2. Continue anyway (not recommended)
-```
-
-**4.2d. Store in Local Encrypted Store**
-
-```python
-from core.framework.credentials import CredentialStore, CredentialObject, CredentialKey
-from pydantic import SecretStr
-
-store = CredentialStore.with_encrypted_storage()
-
-cred = CredentialObject(
-    id="hubspot",
-    name="HubSpot Access Token",
-    keys={
-        "access_token": CredentialKey(
-            name="access_token",
-            value=SecretStr(user_provided_token),
-        )
-    },
-)
-store.save_credential(cred)
-```
-
-**4.2e. Export to Current Session**
-
-```bash
-export HUBSPOT_ACCESS_TOKEN="the-value"
-```
-
-#### Option 3: Local Credential Setup (Advanced)
-
-For programmatic/CI/CD setups.
-
-**4.3a. Show Documentation**
-
-```
-For advanced credential management, you can use the CredentialStore API directly:
-
-  from core.framework.credentials import CredentialStore, CredentialObject, CredentialKey
-  from pydantic import SecretStr
-
-  store = CredentialStore.with_encrypted_storage()
-
-  cred = CredentialObject(
-      id="hubspot",
-      name="HubSpot Access Token",
-      keys={"access_token": CredentialKey(name="access_token", value=SecretStr("..."))}
-  )
-  store.save_credential(cred)
-
-For CI/CD environments:
-  - Set HIVE_CREDENTIAL_KEY for encryption
-  - Pre-populate ~/.hive/credentials programmatically
-  - Or use environment variables directly (HUBSPOT_ACCESS_TOKEN)
-
-Documentation: See core/framework/credentials/README.md
-```
-
-### Step 5: Record Configuration Method
-
-Track which auth method was used for each credential in `~/.hive/configuration.json`:
-
-```python
-import json
-from pathlib import Path
-from datetime import datetime
-
-config_path = Path.home() / ".hive" / "configuration.json"
-config = json.loads(config_path.read_text()) if config_path.exists() else {}
-
-if "credential_methods" not in config:
-    config["credential_methods"] = {}
-
-config["credential_methods"]["hubspot"] = {
-    "method": "aden",  # or "direct" or "custom"
-    "configured_at": datetime.now().isoformat(),
-}
-
-config_path.write_text(json.dumps(config, indent=2))
-```
-
-### Step 6: Verify All Credentials
-
-Use the `verify_credentials` MCP tool to confirm everything is properly configured:
-
-```
-verify_credentials(agent_path="exports/{agent_name}")
-```
-
-The tool returns:
-
-```json
-{
-  "agent": "exports/{agent_name}",
-  "ready": true,
-  "missing_credentials": [],
-  "warnings": [],
-  "errors": []
-}
-```
-
-If `ready` is true, report success. If `missing_credentials` is non-empty, identify what failed and loop back to Step 3 for the remaining credentials.
-
-## Health Check Reference
-
-Health checks validate credentials by making lightweight API calls:
-
-| Credential      | Endpoint                                | What It Checks                    |
-| --------------- | --------------------------------------- | --------------------------------- |
-| `anthropic`     | `POST /v1/messages`                     | API key validity                  |
-| `brave_search`  | `GET /res/v1/web/search?q=test&count=1` | API key validity                  |
-| `google_search` | `GET /customsearch/v1?q=test&num=1`     | API key + CSE ID validity         |
-| `github`        | `GET /user`                             | Token validity, user identity     |
-| `hubspot`       | `GET /crm/v3/objects/contacts?limit=1`  | Bearer token validity, CRM scopes |
-| `resend`        | `GET /domains`                          | API key validity                  |
-
-```python
-from aden_tools.credentials import check_credential_health, HealthCheckResult
-
-result: HealthCheckResult = check_credential_health("hubspot", token_value)
-# result.valid: bool
-# result.message: str
-# result.details: dict (status_code, rate_limited, etc.)
-```
-
-## Encryption Key (HIVE_CREDENTIAL_KEY)
-
-The local encrypted store requires `HIVE_CREDENTIAL_KEY` to encrypt/decrypt credentials.
-
-- If the user doesn't have one, `EncryptedFileStorage` will auto-generate one and log it
-- The user MUST persist this key (e.g., in `~/.bashrc`/`~/.zshrc` or a secrets manager)
-- Without this key, stored credentials cannot be decrypted
-
-**Shell config rule:** Only TWO keys belong in shell config (`~/.zshrc`/`~/.bashrc`):
-- `HIVE_CREDENTIAL_KEY` — encryption key for the credential store
-- `ADEN_API_KEY` — Aden platform auth key (needed before the store can sync)
-
-All other API keys (Brave, Google, HubSpot, etc.) must go in the encrypted store only. **Never offer to add them to shell config.**
-
-If `HIVE_CREDENTIAL_KEY` is not set:
-
-1. Let the store generate one
-2. Tell the user to save it: `export HIVE_CREDENTIAL_KEY="{generated_key}"`
-3. Recommend adding it to `~/.bashrc` or their shell profile
-
-## Security Rules
-
-- **NEVER** log, print, or echo credential values in tool output
-- **NEVER** store credentials in plaintext files, git-tracked files, or agent configs
-- **NEVER** hardcode credentials in source code
-- **NEVER** offer to save API keys to shell config (`~/.zshrc`/`~/.bashrc`) — the **only** keys that belong in shell config are `HIVE_CREDENTIAL_KEY` and `ADEN_API_KEY`. All other credentials (Brave, Google, HubSpot, GitHub, Resend, etc.) go in the encrypted store only.
-- **ALWAYS** use `SecretStr` from Pydantic when handling credential values in Python
-- **ALWAYS** use the local encrypted store (`~/.hive/credentials`) for persistence
-- **ALWAYS** run health checks before storing credentials (when possible)
-- **ALWAYS** verify credentials were stored by re-running validation, not by reading them back
-- When modifying `~/.bashrc` or `~/.zshrc`, confirm with the user first

-## Credential Sources Reference
-
-All credential specs are defined in `tools/src/aden_tools/credentials/`:
-
-| File              | Category      | Credentials                                   | Aden Supported |
-| ----------------- | ------------- | --------------------------------------------- | -------------- |
-| `llm.py`          | LLM Providers | `anthropic`                                   | No             |
-| `search.py`       | Search Tools  | `brave_search`, `google_search`, `google_cse` | No             |
-| `email.py`        | Email         | `resend`                                      | No             |
-| `integrations.py` | Integrations  | `github`, `hubspot`, `google_calendar_oauth`  | No / Yes       |
-
-**Note:** Additional LLM providers (Cerebras, Groq, OpenAI) are handled by LiteLLM via environment
-variables (`CEREBRAS_API_KEY`, `GROQ_API_KEY`, `OPENAI_API_KEY`) but are not yet in CREDENTIAL_SPECS.
-Add them to `llm.py` as needed.
-
-To check what's registered:
-
-```python
-from aden_tools.credentials import CREDENTIAL_SPECS
-for name, spec in CREDENTIAL_SPECS.items():
-    print(f"{name}: aden={spec.aden_supported}, direct={spec.direct_api_key_supported}")
-```
-
-## Migration: CredentialManager → CredentialStore
-
-**CredentialManager is deprecated.** Use CredentialStore instead.
-
-| Old (Deprecated)                          | New (Recommended)                                                    |
-| ----------------------------------------- | -------------------------------------------------------------------- |
-| `CredentialManager()`                     | `CredentialStore.with_encrypted_storage()`                           |
-| `creds.get("hubspot")`                    | `store.get("hubspot")` or `store.get_key("hubspot", "access_token")` |
-| `creds.validate_for_tools(tools)`         | Use `store.is_available(cred_id)` per credential                     |
-| `creds.get_auth_options("hubspot")`       | Check `CREDENTIAL_SPECS["hubspot"].aden_supported`                   |
-| `creds.get_setup_instructions("hubspot")` | Access `CREDENTIAL_SPECS["hubspot"]` directly                        |
-
-**Why migrate?**
-
-- **CredentialStore** supports encrypted storage, multi-key credentials, template resolution, and automatic token refresh
-- **CredentialManager** only reads from environment variables and .env files (no encryption, no refresh)
-- **CredentialStoreAdapter** exists for backward compatibility during migration
-
-```python
-# Old way (deprecated)
-from aden_tools.credentials import CredentialManager
-creds = CredentialManager()
-token = creds.get("hubspot")
-
-# New way (recommended)
-from core.framework.credentials import CredentialStore
-store = CredentialStore.with_encrypted_storage()
-token = store.get("hubspot")
-
-# With Aden sync (recommended for OAuth integrations)
-store = CredentialStore.with_aden_sync()
-token = store.get_key("hubspot", "access_token")
-```

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

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

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

-### ExecutionResult Fields
-
-**`result.success=True` means NO exception, NOT goal achieved**
-
-```python
-# WRONG
-assert result.success
-
-# RIGHT
-assert result.success, f"Agent failed: {result.error}"
-output = result.output or {}
-approval = output.get("approval_decision")
-assert approval == "APPROVED", f"Expected APPROVED, got {approval}"
-```
-
-All fields:
-- `success: bool` — Completed without exception (NOT goal achieved!)
-- `output: dict` — Complete memory snapshot (may contain raw strings)
-- `error: str | None` — Error message if failed
-- `steps_executed: int` — Number of nodes executed
-- `total_tokens: int` — Cumulative token usage
-- `total_latency_ms: int` — Total execution time
-- `path: list[str]` — Node IDs traversed (may repeat in feedback loops)
-- `paused_at: str | None` — Node ID if paused
-- `session_state: dict` — State for resuming
-- `node_visit_counts: dict[str, int]` — Visit counts per node (feedback loop testing)
-- `execution_quality: str` — "clean", "degraded", or "failed"
-
-### Test Count Guidance
-
-**Write 8-15 tests, not 30+**
-
-- 2-3 tests per success criterion
-- 1 happy path test
-- 1 boundary/edge case test
-- 1 error handling test (optional)
-
-Each real test costs ~3 seconds + LLM tokens. 12 tests = ~36 seconds, $0.12.
-
----
-
-## Test Patterns
-
-### Happy Path
-```python
-@pytest.mark.asyncio
-async def test_happy_path(runner, auto_responder, mock_mode):
-    """Test normal successful execution."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": "python tutorials"})
-    finally:
-        await auto_responder.stop()
-    assert result.success, f"Agent failed: {result.error}"
-    output = result.output or {}
-    assert output.get("report"), "No report produced"
-```
-
-### Boundary Condition
-```python
-@pytest.mark.asyncio
-async def test_minimum_sources(runner, auto_responder, mock_mode):
-    """Test at minimum source threshold."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": "niche topic"})
-    finally:
-        await auto_responder.stop()
-    assert result.success, f"Agent failed: {result.error}"
-    output = result.output or {}
-    sources = output.get("sources", [])
-    if isinstance(sources, list):
-        assert len(sources) >= 3, f"Expected >= 3 sources, got {len(sources)}"
-```
-
-### Error Handling
-```python
-@pytest.mark.asyncio
-async def test_empty_input(runner, auto_responder, mock_mode):
-    """Test graceful handling of empty input."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": ""})
-    finally:
-        await auto_responder.stop()
-    # Agent should either fail gracefully or produce an error message
-    output = result.output or {}
-    assert not result.success or output.get("error"), "Should handle empty input"
-```
-
-### Feedback Loop
-```python
-@pytest.mark.asyncio
-async def test_feedback_loop_terminates(runner, auto_responder, mock_mode):
-    """Test that feedback loops don't run forever."""
-    await auto_responder.start()
-    try:
-        result = await runner.run({"query": "test"})
-    finally:
-        await auto_responder.stop()
-    visits = result.node_visit_counts or {}
-    for node_id, count in visits.items():
-        assert count <= 5, f"Node {node_id} visited {count} times — possible infinite loop"
-```
-
----
-
-## MCP Tool Reference
-
-### Phase 1: Test Generation
-
-```python
-# Check existing tests
-list_tests(goal_id, agent_path)
-
-# Get constraint test guidelines (returns templates, NOT generated tests)
-generate_constraint_tests(goal_id, goal_json, agent_path)
-# Returns: output_file, file_header, test_template, constraints_formatted, test_guidelines
-
-# Get success criteria test guidelines
-generate_success_tests(goal_id, goal_json, node_names, tool_names, agent_path)
-# Returns: output_file, file_header, test_template, success_criteria_formatted, test_guidelines
-```
-
-### Phase 2: Execution
-
-```python
-# Automated regression (no checkpoints, fresh runs)
-run_tests(goal_id, agent_path, test_types='["all"]', parallel=-1, fail_fast=False)
-
-# Run only specific test types
-run_tests(goal_id, agent_path, test_types='["constraint"]')
-run_tests(goal_id, agent_path, test_types='["success"]')
-```
-
-```bash
-# Iterative debugging with checkpoints (via CLI)
-uv run hive run exports/{agent_name} --input '{"query": "test"}'
-```
-
-### Phase 3: Analysis
-
-```python
-# Debug a specific failed test
-debug_test(goal_id, test_name, agent_path)
-
-# Find failed sessions
-list_agent_sessions(agent_work_dir, status="failed", limit=5)
-
-# Inspect session state (excludes memory values)
-get_agent_session_state(agent_work_dir, session_id)
-
-# Inspect memory data
-get_agent_session_memory(agent_work_dir, session_id, key="research_results")
-
-# Runtime logs: L1 summaries
-query_runtime_logs(agent_work_dir, status="needs_attention")
-
-# Runtime logs: L2 per-node details
-query_runtime_log_details(agent_work_dir, run_id, needs_attention_only=True)
-
-# Runtime logs: L3 tool/LLM raw data
-query_runtime_log_raw(agent_work_dir, run_id, node_id="research")
-
-# Find clean checkpoints
-list_agent_checkpoints(agent_work_dir, session_id, is_clean="true")
-
-# Compare checkpoints (memory diff)
-compare_agent_checkpoints(agent_work_dir, session_id, cp_before, cp_after)
-```
-
-### Phase 5: Recovery
-
-```python
-# Inspect checkpoint before resuming
-get_agent_checkpoint(agent_work_dir, session_id, checkpoint_id)
-# Empty checkpoint_id = latest checkpoint
-```
-
-```bash
-# Resume from checkpoint via CLI (headless)
-uv run hive run exports/{agent_name} \
-  --resume-session {session_id} --checkpoint {checkpoint_id}
-```
-
----
-
-## Anti-Patterns
-
-| Don't | Do Instead |
-|-------|-----------|
-| Use `default_agent.run()` in tests | Use `runner.run()` with `auto_responder` fixtures (goes through AgentRuntime) |
-| Re-run entire agent when a late node fails | Resume from last clean checkpoint |
-| Treat `result.success` as goal achieved | Check `result.output` for actual criteria |
-| Access `result.output["key"]` directly | Use `result.output.get("key")` |
-| Fix random things hoping tests pass | Analyze L2/L3 logs to find root cause first |
-| Write 30+ tests | Write 8-15 focused tests |
-| Skip credential check | Use `/hive-credentials` before testing |
-| Confuse `exports/` with `~/.hive/agents/` | Code in `exports/`, runtime data in `~/.hive/` |
-| Use `run_tests` for iterative debugging | Use headless CLI with checkpoints for iterative debugging |
-| Use headless CLI for final regression | Use `run_tests` for automated regression |
-| Use `--tui` from Claude Code | Use headless `run` command — TUI hangs in non-interactive shells |
-| Test client-facing nodes from Claude Code | Use mock mode, or have the user run the agent in their terminal |
-| Run tests without reading goal first | Always understand the goal before writing tests |
-| Skip Phase 3 analysis and guess | Use session + log tools to identify root cause |

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

-## Phase 3: Analyze (Iteration 1)

-### Find the session and inspect memory
-
-```python

-    fail_fast=True
-)
-```
-
-**Result:**
-```json
-{
-  "overall_passed": false,
-  "summary": {"total": 5, "passed": 4, "failed": 1, "pass_rate": "80.0%"},
-  "failures": [
-    {"test_name": "test_success_citation_coverage", "details": "AssertionError: Report lacks citations"}
-  ]
-}
-```
-
-Source diversity now passes. Citation coverage still fails.
-
----
-
-## Phase 3: Analyze (Iteration 2)
-
-```python
-debug_test(
-    goal_id="rigorous-interactive-research",
-    test_name="test_success_citation_coverage",
-    agent_path="exports/deep_research_agent"
-)
-# Category: ASSERTION_FAILURE — Report lacks citations
-
-# Check what the report node produced
-list_agent_sessions(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    status="completed",
-    limit=1
-)
-# → session_20260209_151500_def67890
-
-get_agent_session_memory(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    session_id="session_20260209_151500_def67890",
-    key="report"
-)
-# → Report text exists but uses no numbered references.
-# → Sources are in memory but report node doesn't cite them.
-```
-
-**Root cause:** The report node's prompt doesn't instruct the LLM to include numbered citations.
-
----
-
-## Phase 4: Fix (Iteration 2)
-
-```python
-Edit(
-    file_path="exports/deep_research_agent/nodes/__init__.py",
-    old_string='system_prompt="Write a comprehensive report based on the research findings."',
-    new_string='system_prompt="Write a comprehensive report based on the research findings. You MUST include numbered citations [1], [2], etc. for every factual claim. At the end, include a References section listing all sources with their URLs. Every claim must be traceable to a specific source."'
-)
-```
-
----
-
-## Phase 5: Resume (Iteration 2)
-
-The fix is to the `report` node (the last node). To demonstrate checkpoint recovery, run via CLI:
-
-```bash
-# Run via CLI to get checkpoints
-uv run hive run exports/deep_research_agent --input '{"topic": "climate change effects"}'
-
-# After it runs, find the clean checkpoint before report
-list_agent_checkpoints(
-    agent_work_dir="~/.hive/agents/deep_research_agent",
-    session_id="session_20260209_152000_ghi34567",
-    is_clean="true"
-)
-# → cp_node_complete_review_152100 (after review, before report)
-
-# Resume — skips intake, research, review entirely
-uv run hive run exports/deep_research_agent \
-  --resume-session session_20260209_152000_ghi34567 \
-  --checkpoint cp_node_complete_review_152100
-```
-
-Only the `report` node re-runs with the fixed prompt, using research data from the checkpoint.
-
----
-
-## Phase 6: Final Verification
-
-```python
-run_tests(
-    goal_id="rigorous-interactive-research",
-    agent_path="exports/deep_research_agent"
-)
-```
-
-**Result:**
-```json
-{
-  "overall_passed": true,
-  "summary": {"total": 5, "passed": 5, "failed": 0, "pass_rate": "100.0%"}
-}
-```
-
-All tests pass.
-
----
-
-## Summary
-
-| Iteration | Failure | Root Cause | Fix | Recovery |
-|-----------|---------|------------|-----|----------|
-| 1 | Source diversity (2 < 5) | Research prompt too vague | Added "at least 5 sources" to prompt | Re-run (no checkpoints) |
-| 2 | No citations in report | Report prompt lacks citation instructions | Added citation requirements | Checkpoint resume (skipped 3 nodes) |
-
-**Key takeaways:**
-- Phase 3 analysis (session memory + L3 logs) identified root causes without guessing
-- Checkpoint recovery in iteration 2 saved time by skipping 3 expensive nodes
-- Final `run_tests` confirms all scenarios pass end-to-end

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

-→ Tests created and passing
-→ Done: Production-ready agent
-```
-
-### Pattern 1b: Complete New Build (With Learning)
-
-```
-User: "Build an agent (first time)"

-```
-
-### Pattern 3: Iterative Development
-
-```
-User: "Build an agent"
-→ Use /hive-create (Phase 1)
-→ Implementation needed (see STATUS.md)
-→ [User implements functions]

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

-## Summary
-
-This workflow provides a proven path from concept to production-ready agent:
-
-1. **Learn** with `/hive-concepts` → Understand fundamentals (optional)
-2. **Build** with `/hive-create` → Get validated structure
-3. **Optimize** with `/hive-patterns` → Apply best practices (optional)
-4. **Configure** with `/hive-credentials` → Set up API keys (if needed)
-5. **Test** with `/hive-test` → Get verified functionality
-6. **Debug** with `/hive-debugger` → Fix runtime issues (if needed)

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

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

-========================== 12 passed in 3.42s ==========================
-```
-
-**Phase 2 Complete**: All tests pass ✅
-
-## Final Output
-
-**Production-Ready Agent:**
-
-```bash
-# Run the agent
-./RUN_AGENT.sh
-
-# Or manually
-PYTHONPATH=exports uv run python -m file_monitor_agent run
-```
-
-**Capabilities:**
-- Monitors ~/Downloads continuously
-- Copies new files to ~/Documents
-- Resolves conflicts with timestamps
-- Handles errors gracefully
-- Tracks processed files
-- Runs as background service
-
-**Total Time**: ~45 minutes from concept to production
-
-## Key Learnings
-
-1. **Incremental building** - Files written immediately, visible throughout
-2. **Validation early** - Structure validated before moving to implementation
-3. **Test-driven** - Tests reveal real behavior
-4. **Documentation included** - README, STATUS, and guides auto-generated
-5. **Repeatable process** - Same workflow for any agent type
-
-## Variations
-
-**For simpler agents:**
-- Fewer nodes (3-5 instead of 7)
-- Simpler workflow (linear instead of looping)
-- Faster build time (10-15 minutes)
-
-**For complex agents:**
-- More nodes (10-15+)
-- Multiple subgraphs
-- Pause/resume points for human-in-the-loop
-- Longer build time (45-60 minutes)
-
-The workflow scales to your needs!

-## MCP Server Setup
+## Agent Building
 
-The framework includes an MCP (Model Context Protocol) server for building agents. To set up the MCP server:
+Agent scaffolding is handled by the `coder-tools` MCP server (in `tools/coder_tools_server.py`), which provides the `initialize_agent_package` tool and related utilities. The underlying package generation logic lives in `framework.builder.package_generator`.
 
-### Automated Setup
-
-**Using bash (Linux/macOS):**
-```bash
-./setup_mcp.sh
-```
-
-**Using Python (cross-platform):**
-```bash
-python setup_mcp.py
-```
-
-The setup script will:
-1. Install the framework package
-2. Install MCP dependencies (mcp, fastmcp)
-3. Create/verify `.mcp.json` configuration
-4. Test the MCP server module
-
-### Manual Setup
-
-If you prefer manual setup:
-
-```bash
-# Install framework
-uv pip install -e .
-
-# Install MCP dependencies
-uv pip install mcp fastmcp
-
-# Test the server
-uv run python -m framework.mcp.agent_builder_server
-```
-
-### Using with MCP Clients
-
-To use the agent builder with Claude Desktop or other MCP clients, add this to your MCP client configuration:
-
-```json
-{
-  "mcpServers": {
-    "agent-builder": {
-      "command": "python",
-      "args": ["-m", "framework.mcp.agent_builder_server"],
-      "cwd": "/path/to/hive/core"
-    }
-  }
-}
-```
-
-The MCP server provides tools for:
-- Creating agent building sessions
-- Defining goals with success criteria
-- Adding nodes (event_loop only)
-- Connecting nodes with edges
-- Validating and exporting agent graphs
-- Testing nodes and full agent graphs
+See the [Getting Started Guide](../docs/getting-started.md) for building agents.

 # 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`.**
+1. **Using tools that don't exist** — Always verify tools via `list_agent_tools()` before designing. Common hallucinations: `csv_read`, `csv_write`, `file_upload`, `database_query`, `bulk_fetch_emails`.
+2. **Wrong mcp_servers.json format** — Flat dict (no `"mcpServers"` wrapper). `cwd` must be `"../../tools"`. `command` must be `"uv"` with args `["run", "python", ...]`.
+3. **Missing module-level exports in `__init__.py`** — The runner reads `goal`, `nodes`, `edges`, `entry_node`, `entry_points`, `terminal_nodes`, `conversation_mode`, `identity_prompt`, `loop_config` via `getattr()`. 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).
+4. **Fabricating tools** — Always verify via `list_agent_tools()` before designing and `validate_agent_package()` after building.
 
 ## 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.
+5. **Adding framework gating for LLM behavior** — Don't add output rollback or premature rejection. Fix with better prompts or custom judges.
+6. **Calling set_output in same turn as tool calls** — Call set_output in a SEPARATE turn.
 
 ## 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", ...]`.
+7. **Wrong import paths** — Use `from framework.graph import ...`, NOT `from core.framework.graph import ...`.
+8. **Missing storage path** — Agent class must set `self._storage_path = Path.home() / ".hive" / "agents" / "agent_name"`.
+9. **Missing mcp_servers.json** — Without this, the agent has no tools at runtime.
+10. **Bare `python` command** — Use `"command": "uv"` with args `["run", "python", ...]`.
 
 ## Testing Errors
+11. **Using `runner.run()` on forever-alive agents** — `runner.run()` hangs forever because forever-alive agents have no terminal node. Write structural tests instead: validate graph structure, verify node specs, test `AgentRunner.load()` succeeds (no API key needed).
+12. **Stale tests after restructuring** — When changing nodes/edges, update tests to match. Tests referencing old node names will fail.
+13. **Running integration tests without API keys** — Use `pytest.skip()` when credentials are missing.
+14. **Forgetting sys.path setup in conftest.py** — Tests need `exports/` and `core/` on sys.path.
 
-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.
+## GCU Errors
+15. **Manually wiring browser tools on event_loop nodes** — Use `node_type="gcu"` which auto-includes browser tools. Do NOT manually list browser tool names.
+16. **Using GCU nodes as regular graph nodes** — GCU nodes are subagents only. They must ONLY appear in `sub_agents=["gcu-node-id"]` and be invoked via `delegate_to_sub_agent()`. Never connect via edges or use as entry/terminal nodes.
 
-**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.
+## Worker Agent Errors
+17. **Adding client-facing intake node to workers** — The queen owns intake. Workers should start with an autonomous processing node. Client-facing nodes in workers are for mid-execution review/approval only.
+18. **Putting `escalate` or `set_output` in NodeSpec `tools=[]`** — These are synthetic framework tools, auto-injected at runtime. Only list MCP tools from `list_agent_tools()`.

 ## 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)
+For agents that react to external events, use `AsyncEntryPointSpec`:
 
 ```python
+from framework.graph.edge import AsyncEntryPointSpec
 from framework.runtime.agent_runtime import AgentRuntimeConfig
 
+# Timer trigger (cron or interval)
+async_entry_points = [
+    AsyncEntryPointSpec(
+        id="daily-check",
+        name="Daily Check",
+        entry_node="process",
+        trigger_type="timer",
+        trigger_config={"cron": "0 9 * * *"},  # daily at 9am
+        isolation_level="shared",
+    )
+]
+
+# Webhook server (optional)
 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,
+    webhook_routes=[{"source_id": "gmail", "path": "/webhooks/gmail", "methods": ["POST"]}],
 )
 ```
 
-### Reference Agent
+### Key Fields
+- `trigger_type`: `"timer"`, `"event"`, `"webhook"`, `"manual"`
+- `trigger_config`: `{"cron": "0 9 * * *"}` or `{"interval_minutes": 20}`
+- `isolation_level`: `"shared"` (recommended), `"isolated"`, `"synchronized"`
+- `event_types`: For event triggers, e.g., `["webhook_received"]`
 
-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
+### Exports Required
+Both `async_entry_points` and `runtime_config` must be exported from `__init__.py`.
 
-## 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.
+See `exports/gmail_inbox_guardian/agent.py` for complete example.
 
 ## 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.
+Do NOT rely on a static tool list — it will be outdated. Always call
+`list_agent_tools()` with NO arguments first to see ALL available tools.
+Only use `group=` or `output_schema=` as follow-up calls after seeing the
+full list.
 
 ```
-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()                            # ALWAYS call this first
+list_agent_tools(group="gmail", output_schema="full")  # then drill into a category
 list_agent_tools("exports/my_agent/mcp_servers.json")  # specific agent's tools
 ```
 
-After building, validate tools exist: `validate_agent_tools("exports/{name}")`
+After building, run `validate_agent_package("{name}")` to check everything at once.
