Convert a SPEC.md into implementation-ready artifacts and execute the iteration loop. This skill operates in three phases:
Each phase can be entered independently. If you already have a spec.json, start at Phase 2. If artifacts are ready and you need execution, start at Phase 3. If you only need conversion, stop after Phase 1.
When composed by /ship, Ship invokes /implement for the full lifecycle and reviews the output afterward. When standalone, /implement runs end-to-end and reports results directly.
Convert SPEC.md to spec.json, craft the implementation prompt, and execute the iteration loop via subprocess. Use when converting specs to spec.json, preparing implementation artifacts, running the iteration loop, or implementing features autonomously. Triggers: implement, spec.json, convert spec, implementation prompt, execute implementation, run implementation. Source: inkeep/team-skills.
