Reverse-engineers the .teikk/spec/ artifacts from an existing codebase. Use when adopting this skills pack on a legacy or already-built project and you want to skip hand-writing a spec — it scans the code to produce SPEC.md, PROJECT.yaml, QUICKSTART.md, WORKFLOW.md, and a PROJECT-MAP.md. Use instead of /teikk-spec when the project already exists and can be read rather than interviewed.
