-# Agent Development Workflow
-
-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** (5-10 min) → `/building-agents-core` (optional)
-2. **Build Structure** (15-30 min) → `/building-agents-construction`
-3. **Optimize Design** (10-15 min) → `/building-agents-patterns` (optional)
-4. **Test & Validate** (20-40 min) → `/testing-agent`
-
-## 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 `/testing-agent` directly
-- You know exactly which phase you're in → use specific skill directly
-
-## Quick Decision Tree
-
-```
-"Need to understand agent concepts" → building-agents-core
-"Build a new agent" → building-agents-construction
-"Optimize my agent design" → building-agents-patterns
-"Test my agent" → testing-agent
-"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)
-
-**Duration**: 5-10 minutes
-**Skill**: `/building-agents-core`
-**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 pause/resume architecture
-
-### What This Phase Provides
-
-- Architecture overview (Python packages, not JSON)
-- Core concepts (Goal, Node, Edge, Pause/Resume)
-- Tool discovery and validation procedures
-- Workflow overview
-
-**Skip this phase** if you already understand agent fundamentals.
-
-## Phase 1: Build Agent Structure
-
-**Duration**: 15-30 minutes
-**Skill**: `/building-agents-construction`
-**Input**: User requirements ("Build an agent that...")
-
-### 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 `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 building-agents-construction 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 (building-agents-patterns)
-
-**If ready to test:**
-→ Proceed to Phase 2
-
-## Phase 1.5: Optimize Design (Optional)
-
-**Duration**: 10-15 minutes
-**Skill**: `/building-agents-patterns`
-**Input**: Completed agent structure
-
-### When to Use
-
-- Want to add pause/resume functionality
-- Need error handling patterns
-- Want to optimize performance
-- Need examples of complex routing
-- Want best practices guidance
-
-### What This Phase Provides
-
-- Practical examples and patterns
-- Pause/resume architecture
-- Error handling strategies
-- Anti-patterns to avoid
-- Performance optimization techniques
-
-**Skip this phase** if your agent design is straightforward.
-
-## Phase 2: Test & Validate
-
-**Duration**: 20-40 minutes
-**Skill**: `/testing-agent`
-**Input**: Working agent from Phase 1
-
-### What This Phase Does
-
-Creates comprehensive test suite:
-- Constraint tests (verify hard requirements)
-- Success criteria tests (measure goal achievement)
-- Edge case tests (handle failures gracefully)
-- Integration tests (end-to-end workflows)
-
-### Process
-
-1. **Analyze agent** - Read goal, constraints, success criteria
-2. **Generate tests** - Create pytest files in `exports/agent_name/tests/`
-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 /building-agents-construction
-→ Agent structure created
-→ Use /testing-agent
-→ Tests created and passing
-→ Done: Production-ready agent
-```
-
-### Pattern 1b: Complete New Build (With Learning)
-
-```
-User: "Build an agent (first time)"
-→ Use /building-agents-core (understand concepts)
-→ Use /building-agents-construction (build structure)
-→ Use /building-agents-patterns (optimize design)
-→ Use /testing-agent (validate)
-→ Done: Production-ready agent
-```
-
-### Pattern 2: Test Existing Agent
-
-```
-User: "Test my agent at exports/my_agent"
-→ Skip Phase 1
-→ Use /testing-agent directly
-→ Tests created
-→ Done: Validated agent
-```
-
-### Pattern 3: Iterative Development
-
-```
-User: "Build an agent"
-→ Use /building-agents-construction (Phase 1)
-→ Implementation needed (see STATUS.md)

-→ Use /testing-agent (Phase 2)
-→ Tests reveal bugs
-→ [Fix bugs manually]
-→ Re-run tests
-→ Done: Working agent
-```
-
-### Pattern 4: Complex Agent with Patterns
-
-```
-User: "Build an agent with multi-turn conversations"
-→ Use /building-agents-core (learn pause/resume)

-
-## 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=core:exports 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 - building-agents-construction 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 `/testing-agent` to debug and iterate
-- Fix agent code and re-run tests
-
-### "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=core:exports 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

-# Example: File Monitor Agent
-
-This example shows the complete agent-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 `/building-agents` 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=core:exports python -m file_monitor_agent validate
-✓ Agent is valid
-
-$ PYTHONPATH=core:exports 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)
-├── config.py            ✅ (configuration)
-├── implementations.py   ✅ (Python functions)

-├── IMPLEMENTATION_GUIDE.md ✅ (next steps)
-└── 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 `/testing-agent` 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=core:exports pytest exports/file_monitor_agent/tests/
-
-test_constraints.py::test_preserves_originals     PASSED
-test_constraints.py::test_handles_errors          PASSED
-test_constraints.py::test_tracks_state            PASSED
-test_constraints.py::test_respects_permissions    PASSED
-
-test_success_criteria.py::test_detects_all_files  PASSED
-test_success_criteria.py::test_copies_all_files   PASSED
-test_success_criteria.py::test_resolves_conflicts PASSED
-test_success_criteria.py::test_continuous_run     PASSED
-
-test_edge_cases.py::test_empty_directory          PASSED
-test_edge_cases.py::test_permission_denied        PASSED
-test_edge_cases.py::test_disk_full                PASSED
-test_edge_cases.py::test_large_files              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=core:exports:tools/src 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!

-
-# 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:**
-
-- `llm_generate` - Text generation, parsing
-- `llm_tool_use` - Actions requiring tools
-- `router` - Conditional branching
-- `function` - Deterministic operations
-
-```python
-search_node = NodeSpec(
-    id="search-web",
-    name="Search Web",
-    description="Search for information online",
-    node_type="llm_tool_use",
-    input_keys=["query"],
-    output_keys=["search_results"],
-    system_prompt="Search the web for: {query}",
-    tools=["web_search"],
-    max_retries=3,
-)
-```
-
-### Edge
-
-Connection between nodes (written to agent.py)
-
-**Edge Conditions:**
-
-- `on_success` - Proceed if node succeeds
-- `on_failure` - Handle errors
-- `always` - Always proceed
-- `conditional` - Based on expression
-
-```python
-EdgeSpec(
-    id="search-to-analyze",
-    source="search-web",
-    target="analyze-results",
-    condition=EdgeCondition.ON_SUCCESS,
-    priority=1,
-)
-```
-
-### Pause/Resume
-
-Multi-turn conversations
-
-- **Pause nodes** - Stop execution, wait for user input
-- **Resume entry points** - Continue from pause with user's response
-
-```python
-# Example pause/resume configuration
-pause_nodes = ["request-clarification"]
-entry_points = {
-    "start": "analyze-request",
-    "request-clarification_resume": "process-clarification"
-}
-```
-
-## 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")
-```
-
-This returns available tools with their descriptions and parameters:
-
-```json
-{
-  "success": true,
-  "tools_by_server": {
-    "tools": [
-      {
-        "name": "web_search",
-        "description": "Search the web...",
-        "parameters": ["query"]
-      },
-      {
-        "name": "web_scrape",
-        "description": "Scrape a URL...",
-        "parameters": ["url"]
-      }
-    ]
-  },
-  "total_tools": 14
-}
-```
-
-### 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
-
-### Example Validation Flow
-
-```python
-# 1. User requests: "Add a node that searches the web"
-# 2. Discover available tools
-tools_response = mcp__agent-builder__list_mcp_tools()
-
-# 3. Check if web_search exists
-available = [t["name"] for tools in tools_response["tools_by_server"].values() for t in tools]
-if "web_search" not in available:
-    # Inform user and ask how to proceed
-    print("❌ 'web_search' not available. Available tools:", available)
-else:
-    # Proceed with node creation
-    # ...
-```
-
-## 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
-   - User approves
-   - Write to nodes/__init__.py IMMEDIATELY ← FILE WRITTEN
-   - (Optional) Validate with test_node ← MCP VALIDATION
-   - User can open file and see it
-4. CONNECT EDGES → Update agent.py ← FILE WRITTEN
-   - (Optional) Validate with validate_graph ← MCP VALIDATION
-5. FINALIZE → Write agent class to agent.py ← FILE WRITTEN
-6. DONE - Agent ready at exports/my_agent/
-```
-
-**Files written immediately. MCP tools optional for validation/testing bookkeeping.**
-
-### The Key Difference
-
-**OLD (Bad):**
-
-```
-MCP add_node → Session State → MCP add_node → Session State → ...
-                                                                ↓
-                                                     MCP export_graph
-                                                                ↓
-                                                       Files appear
-```
-
-**NEW (Good):**
-
-```
-Write node to file → (Optional: MCP test_node) → Write node to file → ...
-       ↓                                               ↓
-  File visible                                    File visible
-  immediately                                     immediately
-```
-
-**Bottom line:** Use Write/Edit for construction, MCP for validation if needed.
-
-## When to Use This Skill
-
-Use building-agents-core 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 `building-agents-construction` skill
-- Need patterns and examples? → Use `building-agents-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, etc.
-```
-
-**create_session** - Track session state for bookkeeping
-```python
-mcp__agent-builder__create_session(session_name="my-build")
-```
-
-**Key Point:** Files are written FIRST. MCP tools are for validation only.

-# Building Agents - Patterns & Best Practices
-
-Design patterns, examples, and best practices for building robust goal-driven agents.
-
-**Prerequisites:** Complete agent structure using `building-agents-construction`.
-
-## 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="llm_tool_use",
-    input_keys=["query"],
-    output_keys=["search_results"],
-    system_prompt="Search the web for: {query}",
-    tools=["web_search"],
-)
-'''
-
-Edit(
-    file_path="exports/research_agent/nodes/__init__.py",
-    old_string="# Nodes will be added here",
-    new_string=node_code
-)
-
-print("✅ Added search_node to nodes/__init__.py")
-print("📁 Open exports/research_agent/nodes/__init__.py to see it!")
-
-# 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...]}'
-)
-
-print(f"✓ Validation: {validation['success']}")
-```
-
-**User experience:**
-
-- Immediately sees node in their editor (from step 1)
-- Gets validation feedback (from step 2)
-- Can edit the file directly if needed
-
-This combines visibility (files) with validation (MCP tools).
-
-## Pause/Resume Architecture
-
-For agents needing multi-turn conversations with user interaction:
-
-### Basic Pause/Resume Flow
-
-```python
-# Define pause nodes - execution stops at these nodes
-pause_nodes = ["request-clarification", "await-approval"]
-
-# Define entry points - where to resume from each pause
-entry_points = {
-    "start": "analyze-request",  # Initial entry
-    "request-clarification_resume": "process-clarification",  # Resume from clarification
-    "await-approval_resume": "execute-action",  # Resume from approval
-}
-```
-
-### Example: Multi-Turn Research Agent
-
-```python
-# Nodes
-nodes = [
-    NodeSpec(id="analyze-request", ...),
-    NodeSpec(id="request-clarification", ...),  # PAUSE NODE
-    NodeSpec(id="process-clarification", ...),
-    NodeSpec(id="generate-results", ...),
-    NodeSpec(id="await-approval", ...),  # PAUSE NODE
-    NodeSpec(id="execute-action", ...),
-]
-
-# Edges with resume flows
-edges = [
-    EdgeSpec(
-        id="analyze-to-clarify",
-        source="analyze-request",
-        target="request-clarification",
-        condition=EdgeCondition.CONDITIONAL,
-        condition_expr="needs_clarification == true",
-    ),
-    # When resumed, goes to process-clarification
-    EdgeSpec(
-        id="clarify-to-process",
-        source="request-clarification",
-        target="process-clarification",
-        condition=EdgeCondition.ALWAYS,
-    ),
-    EdgeSpec(
-        id="results-to-approval",
-        source="generate-results",
-        target="await-approval",
-        condition=EdgeCondition.ALWAYS,
-    ),
-    # When resumed, goes to execute-action
-    EdgeSpec(
-        id="approval-to-execute",
-        source="await-approval",
-        target="execute-action",
-        condition=EdgeCondition.ALWAYS,
-    ),
-]
-
-# Configuration
-pause_nodes = ["request-clarification", "await-approval"]
-entry_points = {
-    "start": "analyze-request",
-    "request-clarification_resume": "process-clarification",
-    "await-approval_resume": "execute-action",
-}
-```
-
-### Running Pause/Resume Agents
-
-```python
-# Initial run - will pause at first pause node
-result1 = await agent.run(
-    context={"query": "research topic"},
-    session_state=None
-)
-
-# Check if paused
-if result1.paused_at:
-    print(f"Paused at: {result1.paused_at}")
-
-    # Resume with user input
-    result2 = await agent.run(
-        context={"user_response": "clarification details"},
-        session_state=result1.session_state  # Pass previous state
-    )
-```
-
-## Anti-Patterns
-
-### What NOT to Do
-
-❌ **Don't rely on `export_graph`** - Write files immediately, not at end
-```python
-# BAD: Building in session state, exporting at end
-mcp__agent-builder__add_node(...)
-mcp__agent-builder__add_node(...)
-mcp__agent-builder__export_graph()  # Files appear only now
-
-# GOOD: Writing files immediately
-Write(file_path="...", content=node_code)  # File visible now
-Write(file_path="...", content=node_code)  # File visible now
-```
-
-❌ **Don't hide code in session** - Write to files as components approved
-```python
-# BAD: Accumulating changes invisibly
-session.add_component(component1)
-session.add_component(component2)
-# User can't see anything yet
-
-# GOOD: Incremental visibility
-Edit(file_path="...", ...)  # User sees change 1
-Edit(file_path="...", ...)  # User sees change 2
-```
-
-❌ **Don't wait to write files** - Agent visible from first step
-```python
-# BAD: Building everything before writing
-design_all_nodes()
-design_all_edges()
-write_everything_at_once()
-
-# GOOD: Write as you go
-write_package_structure()  # Visible
-write_goal()  # Visible
-write_node_1()  # Visible
-write_node_2()  # Visible
-```
-
-❌ **Don't batch everything** - Write incrementally
-```python
-# BAD: Batching all nodes
-nodes = [design_node_1(), design_node_2(), ...]
-write_all_nodes(nodes)
-
-# GOOD: One at a time with user feedback
-write_node_1()  # User approves
-write_node_2()  # User approves
-write_node_3()  # User approves
-```
-
-### MCP Tools - Correct Usage
-
-**MCP tools OK for:**
-✅ `test_node` - Validate node configuration with mock inputs
-✅ `validate_graph` - Check graph structure
-✅ `create_session` - Track session state for bookkeeping
-✅ Other validation tools
-
-**Just don't:** Use MCP as the primary construction method or rely on export_graph
-
-## Best Practices
-
-### 1. Show Progress After Each Write
-
-```python
-# After writing a node
-print("✅ Added analyze_request_node to nodes/__init__.py")
-print("📊 Progress: 1/6 nodes added")
-print("📁 Open exports/my_agent/nodes/__init__.py to see it!")
-```
-
-### 2. Let User Open Files During Build
-
-```python
-# Encourage file inspection
-print("✅ Goal written to agent.py")
-print("")
-print("💡 Tip: Open exports/my_agent/agent.py in your editor to see the goal!")
-```
-
-### 3. Write Incrementally - One Component at a Time
-
-```python
-# Good flow
-write_package_structure()
-show_user("Package created")
-
-write_goal()
-show_user("Goal written")
-
-for node in nodes:
-    get_approval(node)
-    write_node(node)
-    show_user(f"Node {node.id} written")
-```
-
-### 4. Test As You Build
-
-```python
-# After adding several nodes
-print("💡 You can test current state with:")
-print("  PYTHONPATH=core:exports python -m my_agent validate")
-print("  PYTHONPATH=core:exports python -m my_agent info")
-```
-
-### 5. Keep User Informed
-
-```python
-# Clear status updates
-print("🔨 Creating package structure...")
-print("✅ Package created: exports/my_agent/")
-print("")
-print("📝 Next: Define agent goal")
-```
-
-## Continuous Monitoring Agents
-
-For agents that run continuously without terminal nodes:
-
-```python
-# No terminal nodes - loops forever
-terminal_nodes = []
-
-# Workflow loops back to start
-edges = [
-    EdgeSpec(id="monitor-to-check", source="monitor", target="check-condition"),
-    EdgeSpec(id="check-to-wait", source="check-condition", target="wait"),
-    EdgeSpec(id="wait-to-monitor", source="wait", target="monitor"),  # Loop
-]
-
-# Entry node only
-entry_node = "monitor"
-entry_points = {"start": "monitor"}
-pause_nodes = []
-```
-
-**Example: File Monitor**
-
-```python
-nodes = [
-    NodeSpec(id="list-files", ...),
-    NodeSpec(id="check-new-files", node_type="router", ...),
-    NodeSpec(id="process-files", ...),
-    NodeSpec(id="wait-interval", node_type="function", ...),
-]
-
-edges = [
-    EdgeSpec(id="list-to-check", source="list-files", target="check-new-files"),
-    EdgeSpec(
-        id="check-to-process",
-        source="check-new-files",
-        target="process-files",
-        condition=EdgeCondition.CONDITIONAL,
-        condition_expr="new_files_count > 0",
-    ),
-    EdgeSpec(
-        id="check-to-wait",
-        source="check-new-files",
-        target="wait-interval",
-        condition=EdgeCondition.CONDITIONAL,
-        condition_expr="new_files_count == 0",
-    ),
-    EdgeSpec(id="process-to-wait", source="process-files", target="wait-interval"),
-    EdgeSpec(id="wait-to-list", source="wait-interval", target="list-files"),  # Loop back
-]
-
-terminal_nodes = []  # No terminal - runs forever
-```
-
-## Complex Routing Patterns
-
-### Multi-Condition Router
-
-```python
-router_node = NodeSpec(
-    id="decision-router",
-    node_type="router",
-    input_keys=["analysis_result"],
-    output_keys=["decision"],
-    system_prompt="""
-    Based on the analysis result, decide the next action:
-    - If confidence > 0.9: route to "execute"
-    - If 0.5 <= confidence <= 0.9: route to "review"
-    - If confidence < 0.5: route to "clarify"
-
-    Return: {"decision": "execute|review|clarify"}
-    """,
-)
-
-# Edges for each route
-edges = [
-    EdgeSpec(
-        id="router-to-execute",
-        source="decision-router",
-        target="execute-action",
-        condition=EdgeCondition.CONDITIONAL,
-        condition_expr="decision == 'execute'",
-        priority=1,
-    ),
-    EdgeSpec(
-        id="router-to-review",
-        source="decision-router",
-        target="human-review",
-        condition=EdgeCondition.CONDITIONAL,
-        condition_expr="decision == 'review'",
-        priority=2,
-    ),
-    EdgeSpec(
-        id="router-to-clarify",
-        source="decision-router",
-        target="request-clarification",
-        condition=EdgeCondition.CONDITIONAL,
-        condition_expr="decision == 'clarify'",
-        priority=3,
-    ),
-]
-```
-
-## Error Handling Patterns
-
-### Graceful Failure with Fallback
-
-```python
-# Primary node with error handling
-nodes = [
-    NodeSpec(id="api-call", max_retries=3, ...),
-    NodeSpec(id="fallback-cache", ...),
-    NodeSpec(id="report-error", ...),
-]
-
-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,
-    ),
-]
-```
-
-## Performance Optimization
-
-### Parallel Node Execution
-
-```python
-# Use multiple edges from same source for parallel execution
-edges = [
-    EdgeSpec(
-        id="start-to-search1",
-        source="start",
-        target="search-source-1",
-        condition=EdgeCondition.ALWAYS,
-    ),
-    EdgeSpec(
-        id="start-to-search2",
-        source="start",
-        target="search-source-2",
-        condition=EdgeCondition.ALWAYS,
-    ),
-    EdgeSpec(
-        id="start-to-search3",
-        source="start",
-        target="search-source-3",
-        condition=EdgeCondition.ALWAYS,
-    ),
-    # Converge results
-    EdgeSpec(
-        id="search1-to-merge",
-        source="search-source-1",
-        target="merge-results",
-    ),
-    EdgeSpec(
-        id="search2-to-merge",
-        source="search-source-2",
-        target="merge-results",
-    ),
-    EdgeSpec(
-        id="search3-to-merge",
-        source="search-source-3",
-        target="merge-results",
-    ),
-]
-```
-
-## Handoff to Testing
-
-When agent is complete, transition to testing phase:
-
-```python
-print("""
-✅ Agent complete: exports/my_agent/
-
-Next steps:
-1. Switch to testing-agent skill
-2. Generate and approve tests
-3. Run evaluation
-4. Debug any failures
-
-Command: "Test the agent at exports/my_agent/"
-""")
-```
-
-### Pre-Testing Checklist
-
-Before handing off to testing-agent:
-
-- [ ] Agent structure validates: `python -m agent_name validate`
-- [ ] All nodes defined in nodes/__init__.py
-- [ ] All edges connect valid nodes
-- [ ] Entry node specified
-- [ ] Agent can be imported: `from exports.agent_name import default_agent`
-- [ ] README.md with usage instructions
-- [ ] CLI commands work (info, validate)

-# Example: Testing a YouTube Research Agent
-
-This example walks through testing a YouTube research agent that finds relevant videos based on a topic.
-
-## Prerequisites
-
-- Agent built with building-agents skill at `exports/youtube-research/`
-- Goal defined with success criteria and constraints
-
-## Step 1: Load the Goal
-
-First, load the goal that was defined during the Goal stage:
-
-```json
-{
-    "id": "youtube-research",
-    "name": "YouTube Research Agent",
-    "description": "Find relevant YouTube videos on a given topic",
-    "success_criteria": [
-        {
-            "id": "find_videos",
-            "description": "Find 3-5 relevant videos",
-            "metric": "video_count",
-            "target": "3-5",
-            "weight": 1.0
-        },
-        {
-            "id": "relevance",
-            "description": "Videos must be relevant to the topic",
-            "metric": "relevance_score",
-            "target": ">0.8",
-            "weight": 0.8
-        }
-    ],
-    "constraints": [
-        {
-            "id": "api_limits",
-            "description": "Must not exceed YouTube API rate limits",
-            "constraint_type": "hard",
-            "category": "technical"
-        },
-        {
-            "id": "content_safety",
-            "description": "Must filter out inappropriate content",
-            "constraint_type": "hard",
-            "category": "safety"
-        }
-    ]
-}
-```
-
-## Step 2: Get Constraint Test Guidelines
-
-During the Goal stage (or early Eval), get test guidelines for constraints:
-
-```python
-result = generate_constraint_tests(
-    goal_id="youtube-research",
-    goal_json='<goal JSON above>',
-    agent_path="exports/youtube-research"
-)
-```
-
-**The result contains guidelines (not generated tests):**
-- `output_file`: Where to write tests
-- `file_header`: Imports and fixtures to use
-- `test_template`: Format for test functions
-- `constraints_formatted`: The constraints to test
-- `test_guidelines`: Rules for writing tests
-
-## Step 3: Write Constraint Tests
-
-Using the guidelines, write tests directly with the Write tool:
-
-```python
-# Write constraint tests using the provided file_header and guidelines
-Write(
-    file_path="exports/youtube-research/tests/test_constraints.py",
-    content='''
-"""Constraint tests for youtube-research agent."""
-
-import os
-import pytest
-from exports.youtube_research import default_agent
-
-
-pytestmark = pytest.mark.skipif(
-    not os.environ.get("ANTHROPIC_API_KEY") and not os.environ.get("MOCK_MODE"),
-    reason="API key required for real testing."
-)
-
-
-@pytest.mark.asyncio
-async def test_constraint_api_limits_respected():
-    """Verify API rate limits are not exceeded."""
-    import time
-    mock_mode = bool(os.environ.get("MOCK_MODE"))
-
-    for i in range(10):
-        result = await default_agent.run({"topic": f"test_{i}"}, mock_mode=mock_mode)
-        time.sleep(0.1)
-
-    # Should complete without rate limit errors
-    assert "rate limit" not in str(result).lower()
-
-
-@pytest.mark.asyncio
-async def test_constraint_content_safety_filter():
-    """Verify inappropriate content is filtered."""
-    mock_mode = bool(os.environ.get("MOCK_MODE"))
-    result = await default_agent.run({"topic": "general topic"}, mock_mode=mock_mode)
-
-    for video in result.videos:
-        assert video.safe_for_work is True
-        assert video.age_restricted is False
-'''
-)
-```
-
-## Step 4: Get Success Criteria Test Guidelines
-
-After the agent is built, get success criteria test guidelines:
-
-```python
-result = generate_success_tests(
-    goal_id="youtube-research",
-    goal_json='<goal JSON>',
-    node_names="search_node,filter_node,rank_node,format_node",
-    tool_names="youtube_search,video_details,channel_info",
-    agent_path="exports/youtube-research"
-)
-```
-
-## Step 5: Write Success Criteria Tests
-
-Using the guidelines, write success criteria tests:
-
-```python
-Write(
-    file_path="exports/youtube-research/tests/test_success_criteria.py",
-    content='''
-"""Success criteria tests for youtube-research agent."""
-
-import os
-import pytest
-from exports.youtube_research import default_agent
-
-
-pytestmark = pytest.mark.skipif(
-    not os.environ.get("ANTHROPIC_API_KEY") and not os.environ.get("MOCK_MODE"),
-    reason="API key required for real testing."
-)
-
-
-@pytest.mark.asyncio
-async def test_find_videos_happy_path():
-    """Test finding videos for a common topic."""
-    mock_mode = bool(os.environ.get("MOCK_MODE"))
-    result = await default_agent.run({"topic": "machine learning"}, mock_mode=mock_mode)
-
-    assert result.success
-    assert 3 <= len(result.videos) <= 5
-    assert all(v.title for v in result.videos)
-    assert all(v.video_id for v in result.videos)
-
-
-@pytest.mark.asyncio
-async def test_find_videos_minimum_boundary():
-    """Test at minimum threshold (3 videos)."""
-    mock_mode = bool(os.environ.get("MOCK_MODE"))
-    result = await default_agent.run({"topic": "niche topic xyz"}, mock_mode=mock_mode)
-
-    assert len(result.videos) >= 3
-
-
-@pytest.mark.asyncio
-async def test_relevance_score_threshold():
-    """Test relevance scoring meets threshold."""
-    mock_mode = bool(os.environ.get("MOCK_MODE"))
-    result = await default_agent.run({"topic": "python programming"}, mock_mode=mock_mode)
-
-    for video in result.videos:
-        assert video.relevance_score > 0.8
-
-
-@pytest.mark.asyncio
-async def test_find_videos_no_results_graceful():
-    """Test graceful handling of no results."""
-    mock_mode = bool(os.environ.get("MOCK_MODE"))
-    result = await default_agent.run({"topic": "xyznonexistent123"}, mock_mode=mock_mode)
-
-    # Should not crash, return empty or message
-    assert result.videos == [] or result.message
-'''
-)
-```
-
-## Step 6: Run All Tests
-
-Execute all tests:
-
-```python
-result = run_tests(
-    goal_id="youtube-research",
-    agent_path="exports/youtube-research",
-    test_types='["all"]',
-    parallel=4
-)
-```
-
-**Results:**

-}
-```
-
-## Step 8: Iterate Based on Category
-
-Since this is an **IMPLEMENTATION_ERROR**, we:
-
-1. **Don't restart** the Goal → Agent → Eval flow
-2. **Fix the agent** using building-agents skill:
-   - Modify `filter_node` to handle null results
-3. **Re-run Eval** (tests only)
-
-### Fix in building-agents:
-
-```python
-# Update the filter_node to handle null
-add_node(
-    node_id="filter_node",
-    name="Filter Node",
-    description="Filter and rank videos",
-    node_type="function",
-    input_keys=["search_results"],
-    output_keys=["filtered_videos"],
-    system_prompt="""
-    Filter videos by relevance.
-    IMPORTANT: Handle case where search_results is None or empty.
-    Return empty list if no results.
-    """
-)
-```
-
-### Re-export and re-test:
-
-```python
-# Re-export the fixed agent
-export_graph(path="exports/youtube-research")
-
-# Re-run tests
-result = run_tests(
-    goal_id="youtube-research",
-    agent_path="exports/youtube-research",
-    test_types='["all"]'
-)
-```
-
-**Updated Results:**
-
-```json
-{
-    "goal_id": "youtube-research",
-    "overall_passed": true,
-    "summary": {
-        "total": 6,
-        "passed": 6,
-        "failed": 0,
-        "pass_rate": "100.0%"
-    }
-}
-```
-
-## Summary
-
-1. **Got guidelines** for constraint tests during Goal stage
-2. **Wrote** constraint tests using Write tool
-3. **Got guidelines** for success criteria tests during Eval stage
-4. **Wrote** success criteria tests using Write tool
-5. **Ran** tests in parallel
-6. **Debugged** the one failure
-7. **Categorized** as IMPLEMENTATION_ERROR
-8. **Fixed** the agent (not the goal)
-9. **Re-ran** Eval only (didn't restart full flow)
-10. **Passed** all tests
-
-The agent is now validated and ready for production use.

+# Triage Issue Skill
+
+Analyze a GitHub issue, verify claims against the codebase, and close invalid issues with a technical response.
+
+## Trigger
+
+User provides a GitHub issue URL or number, e.g.:
+- `/triage-issue 1970`
+- `/triage-issue https://github.com/adenhq/hive/issues/1970`
+
+## Workflow
+
+### Step 1: Fetch Issue Details
+
+```bash
+gh issue view <number> --repo adenhq/hive --json title,body,state,labels,author
+```
+
+Extract:
+- Title
+- Body (the claim/bug report)
+- Current state
+- Labels
+- Author
+
+If issue is already closed, inform user and stop.
+
+### Step 2: Analyze the Claim
+
+Read the issue body and identify:
+1. **The core claim** - What is the user asserting?
+2. **Technical specifics** - File paths, function names, code snippets mentioned
+3. **Expected behavior** - What do they think should happen?
+4. **Severity claimed** - Security issue? Bug? Feature request?
+
+### Step 3: Investigate the Codebase
+
+For each technical claim:
+1. Find the referenced code using Grep/Glob/Read
+2. Understand the actual implementation
+3. Check if the claim accurately describes the behavior
+4. Look for related tests, documentation, or design decisions
+
+### Step 4: Evaluate Validity
+
+Categorize the issue as one of:
+
+| Category | Action |
+|----------|--------|
+| **Valid Bug** | Do NOT close. Inform user this is a real issue. |
+| **Valid Feature Request** | Do NOT close. Suggest labeling appropriately. |
+| **Misunderstanding** | Prepare technical explanation for why behavior is correct. |
+| **Fundamentally Flawed** | Prepare critique explaining the technical impossibility or design rationale. |
+| **Duplicate** | Find the original issue and prepare duplicate notice. |
+| **Incomplete** | Prepare request for more information. |
+
+### Step 5: Draft Response
+
+For issues to be closed, draft a response that:
+
+1. **Acknowledges the concern** - Don't be dismissive
+2. **Explains the actual behavior** - With code references
+3. **Provides technical rationale** - Why it works this way
+4. **References industry standards** - If applicable
+5. **Offers alternatives** - If there's a better approach for the user
+
+Use this template:
+
+```markdown
+## Analysis
+
+[Brief summary of what was investigated]
+
+## Technical Details
+
+[Explanation with code references]
+
+## Why This Is Working As Designed
+
+[Rationale]
+
+## Recommendation
+
+[What the user should do instead, if applicable]
+
+---
+*This issue was reviewed and closed by the maintainers.*
+```
+
+### Step 6: User Review
+
+Present the draft to the user with:
+
+```
+## Issue #<number>: <title>
+
+**Claim:** <summary of claim>
+
+**Finding:** <valid/invalid/misunderstanding/etc>
+
+**Draft Response:**
+<the markdown response>
+
+---
+Do you want me to post this comment and close the issue?
+```
+
+Use AskUserQuestion with options:
+- "Post and close" - Post comment, close issue
+- "Edit response" - Let user modify the response
+- "Skip" - Don't take action
+
+### Step 7: Execute Action
+
+If user approves:
+
+```bash
+# Post comment
+gh issue comment <number> --repo adenhq/hive --body "<response>"
+
+# Close issue
+gh issue close <number> --repo adenhq/hive --reason "not planned"
+```
+
+Report success with link to the issue.
+
+## Important Guidelines
+
+1. **Never close valid issues** - If there's any merit to the claim, don't close it
+2. **Be respectful** - The reporter took time to file the issue
+3. **Be technical** - Provide code references and evidence
+4. **Be educational** - Help them understand, don't just dismiss
+5. **Check twice** - Make sure you understand the code before declaring something invalid
+6. **Consider edge cases** - Maybe their environment reveals a real issue
+
+## Example Critiques
+
+### Security Misunderstanding
+> "The claim that secrets are exposed in plaintext misunderstands the encryption architecture. While `SecretStr` is used for logging protection, actual encryption is provided by Fernet (AES-128-CBC) at the storage layer. The code path is: serialize → encrypt → write. Only encrypted bytes touch disk."
+
+### Impossible Request
+> "The requested feature would require [X] which violates [fundamental constraint]. This is not a limitation of our implementation but a fundamental property of [technology/protocol]."
+
+### Already Handled
+> "This scenario is already handled by [code reference]. The reporter may be using an older version or misconfigured environment."

+# Repository Guidelines

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

-All notable changes to this project will be documented in this file.
+**Release Date:** February 18, 2026
+**Tag:** v0.5.1
 
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
-and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+## The Hive Gets a Brain
 
-## [Unreleased]
+v0.5.1 is our most ambitious release yet. Hive agents can now **build other agents** -- the new Hive Coder meta-agent writes, tests, and fixes agent packages from natural language. The runtime grows multi-graph support so one session can orchestrate multiple agents simultaneously. The TUI gets a complete overhaul with an in-app agent picker, live streaming, and seamless escalation to the Coder. And we're now provider-agnostic: Claude Code subscriptions, OpenAI-compatible endpoints, and any LiteLLM-supported model work out of the box.
 
-### Added
-- Initial project structure
-- React frontend (honeycomb) with Vite and TypeScript
-- Node.js backend (hive) with Express and TypeScript
-- Docker Compose configuration for local development
-- Configuration system via `config.yaml`
-- GitHub Actions CI/CD workflows
-- Comprehensive documentation
+---
 
-### Changed
-- N/A
+## Highlights
 
-### Deprecated
-- N/A
+### Hive Coder -- The Agent That Builds Agents
 
-### Removed
-- N/A
+A native meta-agent that lives inside the framework at `core/framework/agents/hive_coder/`. Give it a natural-language specification and it produces a complete agent package -- goal definition, node prompts, edge routing, MCP tool wiring, tests, and all boilerplate files.
 
+```bash
+# Launch the Coder directly
+hive code
 
-### Fixed
-- tools: Fixed web_scrape tool attempting to parse non-HTML content (PDF, JSON) as HTML (#487)
+# Or escalate from any running agent (TUI)
+Ctrl+E  # or /coder in chat
+```
 
-### Security
-- N/A
+The Coder ships with:
 
-## [0.1.0] - 2025-01-13
+- **Reference documentation** -- anti-patterns, construction guide, and design patterns baked into its system prompt
+- **Guardian watchdog** -- an event-driven monitor that catches agent failures and triggers automatic remediation
+- **Coder Tools MCP server** -- file I/O, fuzzy-match editing, git snapshots, and sandboxed shell execution (`tools/coder_tools_server.py`)
+- **Test generation** -- structural tests for forever-alive agents that don't hang on `runner.run()`
 
-### Added
-- Initial release
+### Multi-Graph Agent Runtime
 
-[Unreleased]: https://github.com/adenhq/hive/compare/v0.1.0...HEAD
-[0.1.0]: https://github.com/adenhq/hive/releases/tag/v0.1.0
+`AgentRuntime` now supports loading, managing, and switching between multiple agent graphs within a single session. Six new lifecycle tools give agents (and the TUI) full control:
+
+```python
+# Load a second agent into the runtime
+await runtime.add_graph("exports/deep_research_agent")
+
+# Tools available to agents:
+# load_agent, unload_agent, start_agent, restart_agent, list_agents, get_user_presence
+```
+
+The Hive Coder uses multi-graph internally -- when you escalate from a worker agent, the Coder loads as a separate graph while the worker stays alive in the background.
+
+### TUI Revamp
+
+The Terminal UI gets a ground-up rebuild with five major additions:
+
+- **Agent Picker** (Ctrl+A) -- tabbed modal screen for browsing Your Agents, Framework agents, and Examples with metadata badges (node count, tool count, session count, tags)
+- **Runtime-optional startup** -- TUI launches without a pre-loaded agent, showing the picker on first open
+- **Live streaming pane** -- dedicated RichLog widget shows LLM tokens as they arrive, replacing the old one-token-per-line display
+- **PDF attachments** -- `/attach` and `/detach` commands with native OS file dialog (macOS, Linux, Windows)
+- **Multi-graph commands** -- `/graphs`, `/graph <id>`, `/load <path>`, `/unload <id>` for managing agent graphs in-session
+
+### Provider-Agnostic LLM Support
+
+Hive is no longer Anthropic-only. v0.5.1 adds first-class support for:
+
+- **Claude Code subscriptions** -- `use_claude_code_subscription: true` in `~/.hive/configuration.json` reads OAuth tokens from `~/.claude/.credentials.json` with automatic refresh
+- **OpenAI-compatible endpoints** -- `api_base` config routes traffic through any compatible API (Azure OpenAI, vLLM, Ollama, etc.)
+- **Any LiteLLM model** -- `RuntimeConfig` now passes `api_key`, `api_base`, and `extra_kwargs` through to LiteLLM
+
+The quickstart script auto-detects Claude Code subscriptions and ZAI Code installations.
+
+---
+
+## What's New
+
+### Architecture & Runtime
+
+- **Hive Coder meta-agent** -- Natural-language agent builder with reference docs, guardian watchdog, and `hive code` CLI command. (@TimothyZhang7)
+- **Multi-graph agent sessions** -- `add_graph`/`remove_graph` on AgentRuntime with 6 lifecycle tools (`load_agent`, `unload_agent`, `start_agent`, `restart_agent`, `list_agents`, `get_user_presence`). (@TimothyZhang7)
+- **Claude Code subscription support** -- OAuth token refresh via `use_claude_code_subscription` config, auto-detection in quickstart, LiteLLM header patching. (@TimothyZhang7)
+- **OpenAI-compatible endpoint support** -- `api_base` and `extra_kwargs` in `RuntimeConfig` for any OpenAI-compatible API. (@TimothyZhang7)
+- **Remove deprecated node types** -- Delete `FlexibleGraphExecutor`, `WorkerNode`, `HybridJudge`, `CodeSandbox`, `Plan`, `FunctionNode`, `LLMNode`, `RouterNode`. Deprecated types (`llm_tool_use`, `llm_generate`, `function`, `router`, `human_input`) now raise `RuntimeError` with migration guidance. (@TimothyZhang7)
+- **Interactive credential setup** -- Guided `CredentialSetupSession` with health checks and encrypted storage, accessible via `hive setup-credentials` or automatic prompting on credential errors. (@RichardTang-Aden)
+- **Pre-start confirmation prompt** -- Interactive prompt before agent execution allowing credential updates or abort. (@RichardTang-Aden)
+- **Event bus multi-graph support** -- `graph_id` on events, `filter_graph` on subscriptions, `ESCALATION_REQUESTED` event type, `exclude_own_graph` filter. (@TimothyZhang7)
+
+### TUI Improvements
+
+- **In-app agent picker** (Ctrl+A) -- Tabbed modal for browsing agents with metadata badges (nodes, tools, sessions, tags). (@TimothyZhang7)
+- **Runtime-optional TUI startup** -- Launches without a pre-loaded agent, shows agent picker on startup. (@TimothyZhang7)
+- **Hive Coder escalation** (Ctrl+E) -- Escalate to Hive Coder and return; also available via `/coder` and `/back` chat commands. (@TimothyZhang7)
+- **PDF attachment support** -- `/attach` and `/detach` commands with native OS file dialog. (@TimothyZhang7)
+- **Streaming output pane** -- Dedicated RichLog widget for live LLM token streaming. (@TimothyZhang7)
+- **Multi-graph TUI commands** -- `/graphs`, `/graph <id>`, `/load <path>`, `/unload <id>`. (@TimothyZhang7)
+- **Agent Guardian watchdog** -- Event-driven monitor that catches secondary agent failures and triggers automatic remediation, with `--no-guardian` CLI flag. (@TimothyZhang7)

+
+### Infrastructure
+
+- **Default node type → `event_loop`** -- `NodeSpec.node_type` defaults to `"event_loop"` instead of `"llm_tool_use"`. (@TimothyZhang7)
+- **Default `max_node_visits` → 0 (unlimited)** -- Nodes default to unlimited visits, reducing friction for feedback loops and forever-alive agents. (@TimothyZhang7)
+- **Remove `function` field from NodeSpec** -- Follows deprecation of `FunctionNode`. (@TimothyZhang7)
+- **LiteLLM OAuth patch** -- Correct header construction for OAuth tokens (remove `x-api-key` when Bearer token is present). (@TimothyZhang7)
+- **Orchestrator config centralization** -- Reads `api_key`, `api_base`, `extra_kwargs` from centralized `~/.hive/configuration.json`. (@TimothyZhang7)
+- **System prompt datetime injection** -- All system prompts now include current date/time for time-aware agent behavior. (@TimothyZhang7)
+- **Utils module exports** -- Proper `__init__.py` exports for the utils module. (@Siddharth2624)
+- **Increased default max_tokens** -- Opus 4.6 defaults to 32768, Sonnet 4.5 to 16384 (up from 8192). (@TimothyZhang7)
+
+---
+
+## Bug Fixes
+
+- Flush WIP accumulator outputs on cancel/failure so edge conditions see correct values on resume
+- Stall detection state preserved across resume (no more resets on checkpoint restore)
+- Skip client-facing blocking for event-triggered executions (timer/webhook)
+- Executor retry override scoped to actual EventLoopNode instances only
+- Add `_awaiting_input` flag to EventLoopNode to prevent input injection race conditions
+- Fix TUI streaming display (tokens no longer appear one-per-line)
+- Fix `_return_from_escalation` crash when ChatRepl widgets not yet mounted
+- Fix tools registration problems for Google Docs credentials (@RichardTang-Aden)
+- Fix email agent version conflicts (@RichardTang-Aden)
+- Fix coder tool timeouts (120s for tests, 300s cap for commands)
+
+## Documentation
+
+- Clarify installation and prevent root pip install misuse (@paarths-collab)
+
+---
+
+## Agent Updates
+
+- **Email Inbox Management** -- Consolidate `gmail_inbox_guardian` and `inbox_management` into a single unified agent with updated prompts and config. (@RichardTang-Aden, @bryanadenhq)
+- **Job Hunter** -- Updated node prompts, config, and agent metadata; added PDF resume selection. (@bryanadenhq)
+- **Deep Research Agent** -- Revised node implementations with updated prompts and output handling.
+- **Tech News Reporter** -- Revised node prompts for improved output quality.
+- **Vulnerability Assessment** -- Expanded prompts with more detailed assessment instructions. (@bryanadenhq)
+
+---
+
+## Breaking Changes
+
+- **Deprecated node types raise `RuntimeError`** -- `llm_tool_use`, `llm_generate`, `function`, `router`, `human_input` now fail instead of warning. Migrate to `event_loop`.
+- **`NodeSpec.node_type` defaults to `"event_loop"`** (was `"llm_tool_use"`)
+- **`NodeSpec.max_node_visits` defaults to `0` / unlimited** (was `1`)
+- **`NodeSpec.function` field removed** -- `FunctionNode` is deleted; use event_loop nodes with tools instead.
+
+---
+
+## Community Contributors
+
+A huge thank you to everyone who contributed to this release:
+
+- **Richard Tang** (@RichardTang-Aden) -- Interactive credential setup, pre-start confirmation, email agent consolidation, tool registration fixes, lint and formatting
+- **Pravin Mishra** (@mishrapravin114) -- Discord integration with 4 MCP tools

+
+## Upgrading
+
+```bash
+git pull origin main
+uv sync
+```
+
+### Migration Guide
+
+If your agents use deprecated node types, update them:
+
+```python
+# Before (v0.5.0) -- these now raise RuntimeError
+NodeSpec(node_type="llm_tool_use", ...)
+NodeSpec(node_type="function", function=my_func, ...)
+
+# After (v0.5.1) -- use event_loop for everything
+NodeSpec(node_type="event_loop", ...)  # or just omit node_type (it's the default now)
+```
+
+If your agents set `max_node_visits=1` explicitly, they'll still work. The only change is the _default_ -- new agents without an explicit value now get unlimited visits.
+
+To try the new Hive Coder:
+
+```bash
+# Launch Coder directly
+hive code
+
+# Or from TUI -- press Ctrl+E to escalate
+hive tui
+```
+
+---
+
+## What's Next
+
+- **Agent-to-agent communication** -- one agent's output triggers another agent's entry point
+- **Cost visibility** -- detailed runtime log of LLM costs per node and per session
+- **Persistent webhook subscriptions** -- survive agent restarts without re-registering
+- **Remote agent deployment** -- run agents as long-lived services with HTTP APIs

-# Agent Development Environment Setup
-
-Complete setup guide for building and running goal-driven agents with the Aden Agent Framework.
-
-## Quick Setup
-
-```bash
-# Run the automated setup script
-./scripts/setup-python.sh
-```
-
-> **Note for Windows Users:**  
-> Running the setup script on native Windows shells (PowerShell / Git Bash) may sometimes fail due to Python App Execution Aliases.  
-> It is **strongly recommended to use WSL (Windows Subsystem for Linux)** for a smoother setup experience.
-
-This will:
-
-- Check Python version (requires 3.11+)
-- Install the core framework package (`framework`)
-- Install the tools package (`aden_tools`)
-- Fix package compatibility issues (openai + litellm)
-- Verify all installations
-
-## Alpine Linux Setup
-
-If you are using Alpine Linux (e.g., inside a Docker container), you must install system dependencies and use a virtual environment before running the setup script:
-
-1. Install System Dependencies:
-```bash
-apk update
-apk add bash git python3 py3-pip nodejs npm curl build-base python3-dev linux-headers libffi-dev
-```
-2. Set up Virtual Environment (Required for Python 3.12+):
-```
-python3 -m venv venv
-source venv/bin/activate
-pip install --upgrade pip setuptools wheel
-```
-3. Run the Quickstart Script:
-```
-./quickstart.sh
-```
-
-## Manual Setup (Alternative)
-
-If you prefer to set up manually or the script fails:
-
-### 1. Install Core Framework
-
-```bash
-cd core
-pip install -e .
-```
-
-### 2. Install Tools Package
-
-```bash
-cd tools
-pip install -e .
-```
-
-### 3. Upgrade OpenAI Package
-
-```bash
-# litellm requires openai >= 1.0.0
-pip install --upgrade "openai>=1.0.0"
-```
-
-### 4. Verify Installation
-
-```bash
-python -c "import framework; print('✓ framework OK')"
-python -c "import aden_tools; print('✓ aden_tools OK')"
-python -c "import litellm; print('✓ litellm OK')"
-```
-
-> **Windows Tip:**  
-> On Windows, if the verification commands fail, ensure you are running them in **WSL** or after **disabling Python App Execution Aliases** in Windows Settings → Apps → App Execution Aliases.
-
-## Requirements
-
-### Python Version
-
-- **Minimum:** Python 3.11
-- **Recommended:** Python 3.11 or 3.12
-- **Tested on:** Python 3.11, 3.12, 3.13
-
-### System Requirements
-
-- pip (latest version)
-- 2GB+ RAM
-- Internet connection (for LLM API calls)
-- For Windows users: WSL 2 is recommended for full compatibility.
-
-### API Keys (Optional)
-
-For running agents with real LLMs:
-
-```bash
-export ANTHROPIC_API_KEY="your-key-here"
-```
-
-## Running Agents
-
-All agent commands must be run from the project root with `PYTHONPATH` set:
-
-```bash
-# From /hive/ directory
-PYTHONPATH=core:exports python -m agent_name COMMAND
-```
-
-### Example: Support Ticket Agent
-
-```bash
-# Validate agent structure
-PYTHONPATH=core:exports python -m support_ticket_agent validate
-
-# Show agent information
-PYTHONPATH=core:exports python -m support_ticket_agent info
-
-# Run agent with input
-PYTHONPATH=core:exports python -m support_ticket_agent run --input '{
-  "ticket_content": "My login is broken. Error 401.",
-  "customer_id": "CUST-123",
-  "ticket_id": "TKT-456"
-}'
-
-# Run in mock mode (no LLM calls)
-PYTHONPATH=core:exports python -m support_ticket_agent run --mock --input '{...}'
-```
-
-### Example: Other Agents
-
-```bash
-# Market Research Agent
-PYTHONPATH=core:exports python -m market_research_agent info
-
-# Outbound Sales Agent
-PYTHONPATH=core:exports python -m outbound_sales_agent validate
-
-# Personal Assistant Agent
-PYTHONPATH=core:exports python -m personal_assistant_agent run --input '{...}'
-```
-
-## Building New Agents and Run Flow
-
-Build and run an agent using Claude Code CLI with the agent building skills:
-
-### 1. Install Claude Skills (One-time)
-
-```bash
-./quickstart.sh
-```
-
-This installs agent-related Claude Code skills:
-
-- `/building-agents-construction` - Step-by-step build guide
-- `/building-agents-core` - Fundamental concepts
-- `/building-agents-patterns` - Best practices
-- `/testing-agent` - Test and validate agents
-- `/agent-workflow` - Complete workflow
-
-### 2. Build an Agent
-
-```
-claude> /building-agents-construction
-```
-
-Follow the prompts to:
-
-1. Define your agent's goal
-2. Design the workflow nodes
-3. Connect nodes with edges
-4. Generate the agent package under `exports/`
-
-This step creates the initial agent structure required for further development.
-
-### 3. Define Agent Logic
-
-```
-claude> /building-agents-core
-```
-
-Follow the prompts to:
-
-1. Understand the agent architecture and file structure
-2. Define the agent's goal, success criteria, and constraints
-3. Learn node types (LLM, tool-use, router, function)
-4. Discover and validate available tools before use
-
-This step establishes the core concepts and rules needed before building an agent.
-
-### 4. Apply Agent Patterns
-
-```
-claude> /building-agents-patterns
-```
-
-Follow the prompts to:
-
-1. Apply best-practice agent design patterns
-2. Add pause/resume flows for multi-turn interactions
-3. Improve robustness with routing, fallbacks, and retries
-4. Avoid common anti-patterns during agent construction
-
-This step helps optimize agent design before final testing.
-
-### 5. Test Your Agent
-
-```
-claude> /testing-agent
-```
-Follow the prompts to:
-
-1. Generate test guidelines for constraints and success criteria
-2. Write agent tests directly under `exports/{agent}/tests/`
-3. Run goal-based evaluation tests
-4. Debug failing tests and iterate on agent improvements
-
-This step verifies that the agent meets its goals before production use.
-
-### 6. Agent Development Workflow (End-to-End)
-
-```
-claude> /agent-workflow
-```
-
-Follow the guided flow to:
-
-1. Understand core agent concepts (optional)
-2. Build the agent structure step by step
-3. Apply best-practice design patterns (optional)
-4. Test and validate the agent against its goals
-
-This workflow orchestrates all agent-building skills to take you from idea → production-ready agent.
-
-## Troubleshooting
-
-### "externally-managed-environment" error (PEP 668)
-
-**Cause:** Python 3.12+ on macOS/Homebrew, WSL, or some Linux distros prevents system-wide pip installs.
-
-**Solution:** Create and use a virtual environment:
-
-```bash
-# Create virtual environment
-python3 -m venv .venv
-
-# Activate it
-source .venv/bin/activate  # macOS/Linux
-# .venv\Scripts\activate   # Windows
-
-# Then run setup
-./scripts/setup-python.sh
-```
-
-Always activate the venv before running agents:
-
-```bash
-source .venv/bin/activate
-PYTHONPATH=core:exports python -m your_agent_name demo
-```
-
-### "ModuleNotFoundError: No module named 'framework'"
-
-**Solution:** Install the core package:
-
-```bash
-cd core && pip install -e .
-```
-
-### "ModuleNotFoundError: No module named 'aden_tools'"
-
-**Solution:** Install the tools package:
-
-```bash
-cd tools && pip install -e .
-```
-
-Or run the setup script:
-
-```bash
-./scripts/setup-python.sh
-```
-
-### "ModuleNotFoundError: No module named 'openai.\_models'"
-
-**Cause:** Outdated `openai` package (0.27.x) incompatible with `litellm`
-
-**Solution:** Upgrade openai:
-
-```bash
-pip install --upgrade "openai>=1.0.0"
-```
-
-### "No module named 'support_ticket_agent'"
-
-**Cause:** Not running from project root or missing PYTHONPATH
-
-**Solution:** Ensure you're in the project root directory and use:
-
-```bash
-PYTHONPATH=core:exports python -m support_ticket_agent validate
-```
-
-### Agent imports fail with "broken installation"
-
-**Symptom:** `pip list` shows packages pointing to non-existent directories
-
-**Solution:** Reinstall packages properly:
-
-```bash
-# Remove broken installations
-pip uninstall -y framework tools
-
-# Reinstall correctly
-./scripts/setup-python.sh
-```
-
-## Package Structure
-
-The Hive framework consists of three Python packages:
-
-```
-hive/
-├── core/                    # Core framework (runtime, graph executor, LLM providers)
-│   ├── framework/
-│   ├── pyproject.toml
-│   └── requirements.txt
-│
-├── tools/                   # Tools and MCP servers
-│   ├── src/
-│   │   └── aden_tools/     # Actual package location
-│   ├── pyproject.toml
-│   └── README.md
-│
-└── exports/                 # Agent packages (your agents go here)
-    ├── support_ticket_agent/
-    ├── market_research_agent/
-    ├── outbound_sales_agent/
-    └── personal_assistant_agent/
-```
-
-### Why PYTHONPATH is Required
-
-The packages are installed in **editable mode** (`pip install -e`), which means:
-
-- `framework` and `aden_tools` are globally importable (no PYTHONPATH needed)
-- `exports` is NOT installed as a package (PYTHONPATH required)
-
-This design allows agents in `exports/` to be:
-
-- Developed independently
-- Version controlled separately
-- Deployed as standalone packages
-
-## Development Workflow
-
-### 1. Setup (Once)
-
-```bash
-./scripts/setup-python.sh
-```
-
-### 2. Build Agent (Claude Code)
-
-```
-claude> /building-agents-construction
-Enter goal: "Build an agent that processes customer support tickets"
-```
-
-### 3. Validate Agent
-
-```bash
-PYTHONPATH=core:exports python -m support_ticket_agent validate
-```
-
-### 4. Test Agent
-
-```
-claude> /testing-agent
-```
-
-### 5. Run Agent
-
-```bash
-PYTHONPATH=core:exports python -m support_ticket_agent run --input '{...}'
-```
-
-## IDE Setup
-
-### VSCode
-
-Add to `.vscode/settings.json`:
-
-```json
-{
-  "python.analysis.extraPaths": [
-    "${workspaceFolder}/core",
-    "${workspaceFolder}/exports"
-  ],
-  "python.autoComplete.extraPaths": [
-    "${workspaceFolder}/core",
-    "${workspaceFolder}/exports"
-  ]
-}
-```
-
-### PyCharm
-
-1. Open Project Settings → Project Structure
-2. Mark `core` as Sources Root
-3. Mark `exports` as Sources Root
-
-## Environment Variables
-
-### Required for LLM Operations
-
-```bash
-export ANTHROPIC_API_KEY="sk-ant-..."
-```
-
-### Optional Configuration
-
-```bash
-# Credentials storage location (default: ~/.aden/credentials)
-export ADEN_CREDENTIALS_PATH="/custom/path"
-
-# Agent storage location (default: /tmp)
-export AGENT_STORAGE_PATH="/custom/storage"
-```

 ## Overview
 
-Build reliable, self-improving AI agents without hardcoding workflows. Define your goal through conversation with a coding agent, and the framework generates a node graph with dynamically created connection code. When things break, the framework captures failure data, evolves the agent through the coding agent, and redeploys. Built-in human-in-the-loop nodes, credential management, and real-time monitoring give you control without sacrificing adaptability.

-</p>
+## Who Is Hive For?
 
-Aden is a platform for building, deploying, operating, and adapting AI agents:
+Hive is designed for developers and teams who want to build **production-grade AI agents** without manually wiring complex workflows.
 
-- **Build** - A Coding Agent generates specialized Worker Agents (Sales, Marketing, Ops) from natural language goals
-- **Deploy** - Headless deployment with CI/CD integration and full API lifecycle management
-- **Operate** - Real-time monitoring, observability, and runtime guardrails keep agents reliable
-- **Adapt** - Continuous evaluation, supervision, and adaptation ensure agents improve over time
-- **Infra** - Shared memory, LLM integrations, tools, and skills power every agent
+Hive is a good fit if you:
+
+- Want AI agents that **execute real business processes**, not demos
+- Need **fast or high volume agent execution** over open workflow
+- Need **self-healing and adaptive agents** that improve over time
+- Require **human-in-the-loop control**, observability, and cost limits
+- Plan to run agents in **production environments**
+
+Hive may not be the best fit if you’re only experimenting with simple agent chains or one-off scripts.
+
+## When Should You Use Hive?
+

 ## Quick Start
 
 ### Prerequisites
 
-- [Python 3.11+](https://www.python.org/downloads/) for agent development
-- [Docker](https://docs.docker.com/get-docker/) (v20.10+) - Optional, for containerized tools
+- Python 3.11+ for agent development
+- An LLM provider that powers the agents
+- **ripgrep (optional, recommended on Windows):** The `search_files` tool uses ripgrep for faster file search. If not installed, a Python fallback is used. On Windows: `winget install BurntSushi.ripgrep` or `scoop install ripgrep`
+
+> **Note for Windows Users:** It is strongly recommended to use **WSL (Windows Subsystem for Linux)** or **Git Bash** to run this framework. Some core automation scripts may not execute correctly in standard Command Prompt or PowerShell.
 
 ### Installation
 
+> **Note**
+> Hive uses a `uv` workspace layout and is not installed with `pip install`.
+> Running `pip install -e .` from the repository root will create a placeholder package and Hive will not function correctly.
+> Please use the quickstart script below to set up the environment.
+
 ```bash
 # Clone the repository
-git clone https://github.com/adenhq/hive.git
+git clone https://github.com/aden-hive/hive.git
 cd hive
 
-# Run Python environment setup
-./scripts/setup-python.sh
+
+# Run quickstart setup
+./quickstart.sh
 ```
 
-This installs:
-- **framework** - Core agent runtime and graph executor
-- **aden_tools** - 19 MCP tools for agent capabilities
-- All required dependencies
+This sets up:
+
+- **framework** - Core agent runtime and graph executor (in `core/.venv`)
+- **aden_tools** - MCP tools for agent capabilities (in `tools/.venv`)
+- **credential store** - Encrypted API key storage (`~/.hive/credentials`)
+- **LLM provider** - Interactive default model configuration
+- All required Python dependencies with `uv`
+
+- Finally, it will open the Hive interface in your browser
+
+> **Tip:** To reopen the dashboard later, run `hive open` from the project directory.

-# Test your agent
-claude> /testing-agent
+### Use Template Agents
 
-# Run your agent
-PYTHONPATH=core:exports python -m your_agent_name run --input '{...}'
-```
+Click "Try a sample agent" and check the templates. You can run a template directly or choose to build your version on top of the existing template.
 
-**[📖 Complete Setup Guide](ENVIRONMENT_SETUP.md)** - Detailed instructions for agent development
+### Run Agents
 
-### Cursor IDE Support
+Now you can run an agent by selecting the agent (either an existing agent or example agent). You can click the Run button on the top left, or talk to the queen agent and it can run the agent for you.
 
-Skills are also available in Cursor. To enable:
-
-1. Open Command Palette (`Cmd+Shift+P` / `Ctrl+Shift+P`)
-2. Run `MCP: Enable` to enable MCP servers
-3. Restart Cursor to load the MCP servers from `.cursor/mcp.json`
-4. Type `/` in Agent chat and search for skills (e.g., `/building-agents-construction`)

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

-### The Aden Advantage
+### The Hive Advantage
 
-| Traditional Frameworks     | Aden                                   |
+| Traditional Frameworks     | Hive                                   |
 | -------------------------- | -------------------------------------- |
 | Hardcode agent workflows   | Describe goals in natural language     |
 | Manual graph definition    | Auto-generated agent graphs            |
-| Reactive error handling    | Proactive self-evolution               |
+| Reactive error handling    | Outcome-evaluation and adaptiveness    |
 | Static tool configurations | Dynamic SDK-wrapped nodes              |
 | Separate monitoring setup  | Built-in real-time observability       |
 | DIY budget management      | Integrated cost controls & degradation |
 
 ### How It Works
 
-1. **Define Your Goal** → Describe what you want to achieve in plain English
-2. **Coding Agent Generates** → Creates the agent graph, connection code, and test cases
-3. **Workers Execute** → SDK-wrapped nodes run with full observability and tool access
+1. **[Define Your Goal](docs/key_concepts/goals_outcome.md)** → Describe what you want to achieve in plain English
+2. **Coding Agent Generates** → Creates the [agent graph](docs/key_concepts/graph.md), connection code, and test cases
+3. **[Workers Execute](docs/key_concepts/worker_agent.md)** → SDK-wrapped nodes run with full observability and tool access
 4. **Control Plane Monitors** → Real-time metrics, budget enforcement, policy management
-5. **Self-Improve** → On failure, the system evolves the graph and redeploys automatically
-
-## How Aden Compares
-
-Aden takes a fundamentally different approach to agent development. While most frameworks require you to hardcode workflows or manually define agent graphs, Aden uses a **coding agent to generate your entire agent system** from natural language goals. When agents fail, the framework doesn't just log errors—it **automatically evolves the agent graph** and redeploys.

 ## Frequently Asked Questions (FAQ)
 
-**Q: Does Aden depend on LangChain or other agent frameworks?**
+**Q: What LLM providers does Hive support?**
 
-No. Aden is built from the ground up with no dependencies on LangChain, CrewAI, or other agent frameworks. The framework is designed to be lean and flexible, generating agent graphs dynamically rather than relying on predefined components.
+Hive supports 100+ LLM providers through LiteLLM integration, including OpenAI (GPT-4, GPT-4o), Anthropic (Claude models), Google Gemini, DeepSeek, Mistral, Groq, and many more. Simply set the appropriate API key environment variable and specify the model name. We recommend using Claude, GLM and Gemini as they have the best performance.

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

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

+# Common Mistakes When Building Hive Agents
+
+## Critical Errors
+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
+4. **Fabricating tools** — Always verify via `list_agent_tools()` before designing and `validate_agent_package()` after building.
+
+## Design Errors
+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
+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.
+
+## 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.
+
+## 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()`.

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

+# Hive Agent Framework — Condensed Reference
+
+## Architecture
+
+Agents are Python packages in `exports/`:
+```
+exports/my_agent/
+├── __init__.py          # MUST re-export ALL module-level vars from agent.py
+├── __main__.py          # CLI (run, tui, info, validate, shell)
+├── agent.py             # Graph construction (goal, edges, agent class)
+├── config.py            # Runtime config
+├── nodes/__init__.py    # Node definitions (NodeSpec)
+├── mcp_servers.json     # MCP tool server config
+└── tests/               # pytest tests
+```
+
+## Agent Loading Contract
+
+`AgentRunner.load()` imports the package (`__init__.py`) and reads these
+module-level variables via `getattr()`:
+
+| Variable | Required | Default if missing | Consequence |
+|----------|----------|--------------------|-------------|
+| `goal` | YES | `None` | **FATAL** — "must define goal, nodes, edges" |
+| `nodes` | YES | `None` | **FATAL** — same error |
+| `edges` | YES | `None` | **FATAL** — same error |
+| `entry_node` | no | `nodes[0].id` | Probably wrong node |
+| `entry_points` | no | `{}` | **Nodes unreachable** — validation fails |
+| `terminal_nodes` | **YES** | `[]` | **FATAL** — graph must have at least one terminal node |
+| `pause_nodes` | no | `[]` | OK |
+| `conversation_mode` | no | not passed | Isolated mode (no context carryover) |
+| `identity_prompt` | no | not passed | No agent-level identity |
+| `loop_config` | no | `{}` | No iteration limits |
+| `async_entry_points` | no | `[]` | No async triggers (timers, webhooks, events) |
+| `runtime_config` | no | `None` | No webhook server |
+
+**CRITICAL:** `__init__.py` MUST import and re-export ALL of these from
+`agent.py`. Missing exports silently fall back to defaults, causing
+hard-to-debug failures.
+
+**Why `default_agent.validate()` is NOT sufficient:**
+`validate()` checks the agent CLASS's internal graph (self.nodes, self.edges).
+These are always correct because the constructor references agent.py's module
+vars directly. But `AgentRunner.load()` reads from the PACKAGE (`__init__.py`),
+not the class. So `validate()` passes while `AgentRunner.load()` fails.
+Always test with `AgentRunner.load("exports/{name}")` — this is the same
+code path the TUI and `hive run` use.
+
+## Goal
+
+Defines success criteria and constraints:
+```python
+goal = Goal(
+    id="kebab-case-id",
+    name="Display Name",
+    description="What the agent does",
+    success_criteria=[
+        SuccessCriterion(id="sc-id", description="...", metric="...", target="...", weight=0.25),
+    ],
+    constraints=[
+        Constraint(id="c-id", description="...", constraint_type="hard", category="quality"),
+    ],
+)
+```
+- 3-5 success criteria, weights sum to 1.0
+- 1-5 constraints (hard/soft, categories: quality, accuracy, interaction, functional)
+
+## NodeSpec Fields
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| id | str | required | kebab-case identifier |
+| name | str | required | Display name |
+| description | str | required | What the node does |
+| node_type | str | required | `"event_loop"` or `"gcu"` (browser automation — see GCU Guide appendix) |
+| input_keys | list[str] | required | Memory keys this node reads |
+| output_keys | list[str] | required | Memory keys this node writes via set_output |
+| system_prompt | str | "" | LLM instructions |
+| tools | list[str] | [] | Tool names from MCP servers |
+| client_facing | bool | False | If True, streams to user and blocks for input |
+| nullable_output_keys | list[str] | [] | Keys that may remain unset |
+| max_node_visits | int | 0 | 0=unlimited (default); >1 for one-shot feedback loops |
+| max_retries | int | 3 | Retries on failure |
+| success_criteria | str | "" | Natural language for judge evaluation |
+
+## EdgeSpec Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| id | str | kebab-case identifier |
+| source | str | Source node ID |
+| target | str | Target node ID |
+| condition | EdgeCondition | ON_SUCCESS, ON_FAILURE, ALWAYS, CONDITIONAL |
+| condition_expr | str | Python expression evaluated against memory (for CONDITIONAL) |
+| priority | int | Positive=forward (evaluated first), negative=feedback (loop-back) |
+
+## Key Patterns
+
+### STEP 1/STEP 2 (Client-Facing Nodes)
+```
+**STEP 1 — Respond to the user (text only, NO tool calls):**
+[Present information, ask questions]
+
+**STEP 2 — After the user responds, call set_output:**
+- set_output("key", "value based on user response")
+```
+This prevents premature set_output before user interaction.
+
+### Fewer, Richer Nodes (CRITICAL)
+
+**Hard limit: 3-6 nodes for most agents.** Never exceed 6 unless the user
+explicitly requests a complex multi-phase pipeline.
+
+Each node boundary serializes outputs to shared memory and **destroys** all
+in-context information: tool call results, intermediate reasoning, conversation
+history. A research node that searches, fetches, and analyzes in ONE node keeps
+all source material in its conversation context. Split across 3 nodes, each
+downstream node only sees the serialized summary string.
+
+**Decision framework — merge unless ANY of these apply:**
+1. **Client-facing boundary** — Autonomous and client-facing work MUST be
+   separate nodes (different interaction models)
+2. **Disjoint tool sets** — If tools are fundamentally different (e.g., web
+   search vs database), separate nodes make sense
+3. **Parallel execution** — Fan-out branches must be separate nodes
+
+**Red flags that you have too many nodes:**
+- A node with 0 tools (pure LLM reasoning) → merge into predecessor/successor
+- A node that sets only 1 trivial output → collapse into predecessor
+- Multiple consecutive autonomous nodes → combine into one rich node
+- A "report" node that presents analysis → merge into the client-facing node
+- A "confirm" or "schedule" node that doesn't call any external service → remove
+
+**Typical agent structure (2 nodes):**
+```
+process (autonomous) ←→ review (client-facing)
+```
+The queen owns intake — she gathers requirements from the user, then
+passes structured input via `run_agent_with_input(task)`. When building
+the agent, design the entry node's `input_keys` to match what the queen
+will provide at run time. Worker agents should NOT have a client-facing
+intake node. Client-facing nodes are for mid-execution review/approval only.
+
+For simpler agents, just 1 autonomous node:
+```
+process (autonomous) — loops back to itself
+```
+
+### nullable_output_keys
+For inputs that only arrive on certain edges:
+```python
+research_node = NodeSpec(
+    input_keys=["brief", "feedback"],
+    nullable_output_keys=["feedback"],  # Only present on feedback edge
+    max_node_visits=3,
+)
+```
+
+### Mutually Exclusive Outputs
+For routing decisions:
+```python
+review_node = NodeSpec(
+    output_keys=["approved", "feedback"],
+    nullable_output_keys=["approved", "feedback"],  # Node sets one or the other
+)
+```
+
+### Continuous Loop Pattern
+Mark the primary event_loop node as terminal: `terminal_nodes=["process"]`.
+The node has `output_keys` and can complete when the agent finishes its work.
+Use `conversation_mode="continuous"` to preserve context across transitions.
+
+### set_output
+- Synthetic tool injected by framework
+- Call separately from real tool calls (separate turn)
+- `set_output("key", "value")` stores to shared memory
+
+## Edge Conditions
+
+| Condition | When |
+|-----------|------|
+| ON_SUCCESS | Node completed successfully |
+| ON_FAILURE | Node failed |
+| ALWAYS | Unconditional |
+| CONDITIONAL | condition_expr evaluates to True against memory |
+
+condition_expr examples:
+- `"needs_more_research == True"`
+- `"str(next_action).lower() == 'new_agent'"`
+- `"feedback is not None"`
+
+## Graph Lifecycle
+
+| Pattern | terminal_nodes | When |
+|---------|---------------|------|
+| **Continuous loop** | `["node-with-output-keys"]` | **DEFAULT for all agents** |
+| Linear | `["last-node"]` | One-shot/batch agents |
+
+**Every graph must have at least one terminal node.** Terminal nodes
+define where execution ends. For interactive agents that loop continuously,
+mark the primary event_loop node as terminal (it has `output_keys` and can
+complete at any point). The framework default for `max_node_visits` is 0
+(unbounded), so nodes work correctly in continuous loops without explicit
+override. Only set `max_node_visits > 0` in one-shot agents with feedback loops.
+Every node must have at least one outgoing edge — no dead ends.
+
+## Continuous Conversation Mode
+
+`conversation_mode` has ONLY two valid states:
+- `"continuous"` — recommended for interactive agents
+- Omit entirely — isolated per-node conversations (each node starts fresh)
+
+**INVALID values** (do NOT use): `"client_facing"`, `"interactive"`,
+`"adaptive"`, `"shared"`. These do not exist in the framework.
+
+When `conversation_mode="continuous"`:
+- Same conversation thread carries across node transitions
+- Layered system prompts: identity (agent-level) + narrative + focus (per-node)
+- Transition markers inserted at boundaries
+- Compaction happens opportunistically at phase transitions
+
+## loop_config
+
+Only three valid keys:
+```python
+loop_config = {
+    "max_iterations": 100,          # Max LLM turns per node visit
+    "max_tool_calls_per_turn": 20,  # Max tool calls per LLM response
+    "max_context_tokens": 32000,    # Triggers conversation compaction
+}
+```
+**INVALID keys** (do NOT use): `"strategy"`, `"mode"`, `"timeout"`,
+`"temperature"`. These are silently ignored or cause errors.
+
+## Data Tools (Spillover)
+
+For large data that exceeds context:
+- `save_data(filename, data)` — Write to session data dir
+- `load_data(filename, offset, limit)` — Read with pagination
+- `list_data_files()` — List files
+- `serve_file_to_user(filename, label)` — Clickable file:// URI
+
+`data_dir` is auto-injected by framework — LLM never sees it.
+
+## Fan-Out / Fan-In
+
+Multiple ON_SUCCESS edges from same source → parallel execution via asyncio.gather().
+- Parallel nodes must have disjoint output_keys
+- Only one branch may have client_facing nodes
+- Fan-in node gets all outputs in shared memory
+
+## Judge System
+
+- **Implicit** (default): ACCEPTs when LLM finishes with no tool calls and all required outputs set
+- **SchemaJudge**: Validates against Pydantic model
+- **Custom**: Implement `evaluate(context) -> JudgeVerdict`
+
+Judge is the SOLE acceptance mechanism — no ad-hoc framework gating.
+
+## Async Entry Points (Webhooks, Timers, Events)
+
+For agents that 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(

+
+### 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"]`
+
+### Exports Required
+Both `async_entry_points` and `runtime_config` must be exported from `__init__.py`.
+
+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 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()                            # 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, run `validate_agent_package("{name}")` to check everything at once.
+
+Common tool categories (verify via list_agent_tools):
+- **Web**: search, scrape, PDF
+- **Data**: save/load/append/list data files, serve to user
+- **File**: view, write, replace, diff, list, grep
+- **Communication**: email, gmail, slack, telegram
+- **CRM**: hubspot, apollo, calcom
+- **GitHub**: stargazers, user profiles, repos
+- **Vision**: image analysis
+- **Time**: current time

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

+## The three memory tiers
+
+| File | Tier | Written by | Read at |
+|---|---|---|---|
+| `MEMORY.md` | Semantic | Consolidation LLM (auto, post-session) | Session start (injected into system prompt) |
+| `memories/MEMORY-YYYY-MM-DD.md` | Episodic | Queen via `write_to_diary` tool + consolidation LLM | Session start (today's file injected) |
+| `data/adapt.md` | Working | Queen via `update_session_notes` tool | Every turn (inlined in system prompt) |
+
+---
+
+## Session directory naming
+
+The session directory name is **`queen_resume_from`** when a cold-restore resumes an existing
+session, otherwise the new **`session_id`**. This means resumed sessions accumulate all messages
+in the original directory rather than fragmenting across multiple folders.
+
+---
+
+## Consolidation
+
+`consolidate_queen_memory()` runs every **5 minutes** in the background and once more at session
+end. It reads:
+
+1. `conversations/parts/*.json` — full message history (user + assistant turns; tool results skipped)
+2. `data/adapt.md` — current working notes
+
+It then makes two LLM writes:
+
+- Rewrites `MEMORY.md` in place (semantic memory — queen never touches this herself)
+- Appends a timestamped prose entry to today's `memories/MEMORY-YYYY-MM-DD.md`
+
+If the combined transcript exceeds ~200 K characters it is recursively binary-compacted via the
+LLM before being sent to the consolidation model (mirrors `EventLoopNode._llm_compact`).
