What problem does it solve?
It prevents slow, error-prone implementation by enforcing phase-by-phase execution, post-phase verification, and Codex-assisted correction aligned to the approved plan.
Core Features & Use Cases
- Phase-driven implementation: Executes the changes specified in
tasks/plan.md while reading all relevant files before editing.
- Mismatch handling with safety gates: Detects structural mismatches, triggers targeted re-research, and stops when the plan premise is invalidated or when recovery attempts exceed limits.
- Independent Codex code review and triaged fixes: Runs a Codex review, triages findings into fixes vs developer flags, applies fixes via a child process, and performs a final test/lint verification.
- Commit-per-phase traceability: Creates separate commits for each phase to keep reviews and rollbacks manageable.
Quick Start
Use the implement skill when you already have tasks/plan.md and tasks/research-codebase.md prepared, so it can execute the approved phases, run Codex review, apply fixes, and leave the repo in a verified state.
