## Wiring

- **Entry Point**: PreToolUse hook on Task tool
- **Registration**: `.claude/settings.json` line 45
- **Call Path**: hook → pre-tool-use.ts → scripts/orchestrate.py → orchestration_layer.py
- **Test**: `tests/integration/task_orchestration_test.py`

# BAD: Created orchestration_layer.py with 500 lines
# But nothing imports it or calls it
# Result: Dead code, wasted effort

# GOOD: Start with minimal wiring, then expand
# 1. Create hook (10 lines)
# 2. Test hook fires
# 3. Add script (20 lines)
# 4. Test script executes
# 5. Add module logic (iterate)

# BAD: Agent router has dispatch logic
# AND skill-rules.json has agent selection logic
# AND hooks have agent filtering logic
# Result: Three places to update, routing conflicts

# GOOD: Single source of truth for routing
# skill-rules.json activates skill → skill calls router → router dispatches

# BAD: Assume because you wrote the code, it's imported
from orchestration_layer import dispatch  # Does this path exist?

# GOOD: Verify imports at integration test time
uv run python -c "from orchestration_layer import dispatch; print('OK')"

# BAD: Only unit test
pytest tests/unit/  # All pass, but nothing works end-to-end

# GOOD: Integration test the wiring
pytest tests/integration/  # Verify full call path

// .claude/settings.json - hook definition exists but not in hooks section

  "hooks": {
    "PreToolUse": []  // Empty! Your hook never fires

# Script exists but can't execute
-rw-r--r-- scripts/orchestrate.py

# Fix: Make executable
chmod +x scripts/orchestrate.py

# Script tries to import but path is wrong
from orchestration_layer import dispatch
# ModuleNotFoundError

# Fix: Add to Python path or use proper package structure
sys.path.insert(0, str(Path(__file__).parent.parent))

# BAD: Router has beautiful mapping

    "implement": ImplementAgent,
    "research": ResearchAgent,
