When implementing feature code against a specification
When running per-task tests during implementation
When validating implementation against specification requirements

Key Principle

Every line of code must trace back to a specification requirement. Code quality must meet constitution standards. Tests must verify acceptance criteria from the task definition.

Process

Prepare environment - Scaffold directories and configuration
Execute independent tasks - Parallel execution for tasks without dependencies
Execute dependent tasks - Sequential execution respecting dependency graph
Run per-task tests - Verify each task's acceptance criteria
Validate against spec - Check requirement coverage and story satisfaction
Run integration tests - Cross-component testing
Human review - Approve implementation before quality checklist
