Crank Skill

Quick Ref: Autonomous epic execution. /swarm for each wave with runtime-native spawning. Output: closed issues + phase-2 handoff for /validation.

YOU MUST EXECUTE THIS WORKFLOW. Do not just describe it.

Loop position

Move 5 (wave execution) of the operating loop. Consumes the slice validation plan; produces wave-by-wave slice completion via /swarm + /implement. Hard gate at wave start: every row of the wave-validity check must pass (distinct write scopes, no shared migration/contract/CLI surface, declared integration order, owner per slice, discard path per slice). Any failed row → run those slices sequential, not parallel. Parallelism is explicit ownership, not swarm chaos.

Autonomous execution: implement all issues until the epic is DONE.

CLI dependencies: bd (issue tracking), ao (knowledge flywheel). Both optional — see skills/shared/SKILL.md for fallback table. If bd is unavailable, use TaskList for issue tracking and skip beads sync. If ao is unavailable, skip knowledge injection/extraction.

Architecture: Crank + Swarm

Crank owns orchestration, epic/task lifecycle, and knowledge-flywheel steps. Swarm owns runtime-native worker spawning, fresh-context isolation, per-wave execution, and cleanup. In beads mode Crank gets each wave from bd ready, bridges issues into worker tasks, verifies results, and syncs status back to beads. In TaskList mode the same loop runs over pending unblocked tasks instead of beads issues.
