What problem does it solve? Turning an agreed design into working code often fails because the work is tackled in the wrong order or in chunks too large to review, test, and revert safely. This Skill breaks a design into a sequenced checklist of small, independently mergeable steps so delivery supports continuous integration. ## Core Features & Use Cases - Thinnest-first slicing: Identifies the smallest end-to-end slice (walking skeleton, riskiest integration, or flagged path) to anchor the plan. - Risk-ordered decomposition: Schedules steps carrying unknowns before merely laborious work, with each step tagged by mode (AFK or HITL), pass/fail signal, and any flag, fixture, or migration dependency. - Plan store integration: Discovers the project's design, specification, and plan stores and writes the plan in the store's own format without touching any source code. - Use Case: After agreeing on a design for a new /orders endpoint with idempotency, invoke this Skill to produce a numbered checklist from route scaffolding through migration, handler, idempotency, flag-gated rollout, and flag removal. ## Quick Start Ask the agent to break the agreed design into a sequenced implementation plan of small, independently mergeable steps.
