Coordinate a structured 7-phase feature delivery workflow for non-trivial feature development. Use when a task needs scoped intent, repository behavior tracing, ambiguity resolution, design choices, controlled implementation, assurance, and end-state reporting.
Audit implementation changes for correctness and reliability. Use when validating provided diffs or ranges and producing evidence-backed findings before closure.
Trace how the current repository behaves for a target feature. Use for discovery/behavior tracing of trigger points, execution paths, data contracts, system boundaries, and must-read files before changing code.
Turn clarified requirements into an implementation strategy anchored in repository realities. Use when defining module boundaries, interface updates, file-level work maps, and sequencing.
