What problem does it solve? Running a complex engineering objective end to end often stalls because work is unplanned, self-approved, or lost when a session is interrupted. This Skill runs an objective through gated, repeatable cycles with independent review and durable state so progress compounds instead of restarting. ## Core Features & Use Cases - Gated five-phase cycles: Runs BRAINSTORM, PLAN, BUILD, REVIEW, and IMPROVE phases, each with entry and exit gates backed by concrete evidence. - Generator/verifier separation: Delegates implementation, independent review, and critic challenge to separate contexts so no context approves its own work. - Durable resumable state: Persists cycle, phase, gate outcomes, and learnings under .swarm/loop/<run-id>/ so a killed session resumes without losing or redoing work. - Defense-in-depth stop conditions: Stops on objective met, cycle budget, plateau, oscillation, unrecoverable error, or explicit user request. - Use Case: Ask the agent to add rate limiting to a public API; it brainstorms a spec, plans tasks, implements them, passes independent review and critic gates, captures learnings, and loops until the success criteria pass or the budget is exhausted. ## Quick Start Run the loop mode on my objective to add rate limiting to the public API with at most three cycles and checkpoint autonomy.
