slice-resume
Use when continuing a vertical slice that was stopped mid-build — context exhausted, user ran /clear, session ended, validator stuck, or manual pause. Reads PROGRESS.md + INTAKE.md from the slice directory and picks up at the exact documented checkpoint without re-asking Phase 1 questions. Companion to /slice. Uses the same sub-agent delegation pattern. Invoked as /slice-resume or /slice-resume <SLICE_ID>.
