Completion Check: Verify Infrastructure Is Wired
When building infrastructure, verify it's actually connected to the system before marking as complete.
Pattern
Infrastructure is not done when the code is written - it's done when it's wired into the system and actively used. Dead code (built but never called) is wasted effort.
DO
- Trace the execution path - Follow from user intent to actual code execution:
# Example: Verify Task tool spawns correctly grep -r "claude -p" src/ grep -r "Task(" src/ - Check hooks are registered, not just implemented:
# Hook exists? ls -la.claude/hooks/my-hook.sh # Hook registered in settings? grep "my-hook".claude/settings.json - Verify database connections - Ensure infrastructure uses the right backend:
# Check connection strings grep -r "postgresql://" src/ grep -r "sqlite:" src/ # Should NOT find if PostgreSQL expected - Test end-to-end - Run the feature and verify infrastructure is invoked:
# Add debug logging echo "DEBUG: DAG spawn invoked" >> /tmp/debug.log # Trigger feature uv run python -m my_feature # Verify infrastructure was called cat /tmp/debug.log - Search for orphaned implementations:
# Find functions defined but never called ast-grep --pattern 'async function $NAME() {$$$}' | \ xargs -I {} grep -r "{}" src/
DON'T
- Mark infrastructure "complete" without testing execution path
- Assume code is wired just because it exists
- Build parallel systems (Task tool vs claude -p spawn)
- Use wrong backends (SQLite when PostgreSQL is architected)
- Skip end-to-end testing ("it compiles" ≠ "it runs")
Completion Checklist
Before declaring infrastructure complete:
- Traced execution path from entry point to infrastructure
- Verified hooks are registered in.claude/settings.json
- Confirmed correct database/backend in use
- Ran end-to-end test showing infrastructure invoked
- Searched for dead code or parallel implementations
- Checked configuration files match implementation
Example: DAG Task Graph
Wrong approach:
✓ Built BeadsTaskGraph class
✓ Implemented DAG dependencies
✓ Added spawn logic
✗ Never wired - Task tool still runs instead
✗ Used SQLite instead of PostgreSQLRight approach:
✓ Built BeadsTaskGraph class
✓ Wired into Task tool execution path
✓ Verified claude -p spawn is called
✓ Confirmed PostgreSQL backend in use
✓ Tested: user calls Task() → DAG spawns → beads execute
✓ No parallel implementations foundSource Sessions
