implement-plan

What problem does it solve? Turning an approved plan, PRD, or checklist into actual code changes often leads to scope creep, skipped verification, or lost progress when context runs out. This Skill enforces disciplined execution of approved plans while preserving existing work and verifying results before claiming completion. ## Core Features & Use Cases - Scoped Plan Execution: Locates the approved plan, reads it fully, and implements tasks in dependency order without expanding scope or reworking completed items. - Verification Discipline: Runs the smallest meaningful set of checks (tests, type checking, lint) at natural boundaries and makes one targeted fix per failure instead of repeating failed theories. - Resume and Handoff Support: Maintains compact progress records so work can resume after context compaction or across sessions, reconciling stale notes with actual git state. - Use Case: You have an approved multi-phase refactoring plan in a Markdown checklist. Ask the assistant to implement the next phase, and it will execute the tasks, run focused checks, update the checklist, and report blockers without committing without authorization. ## Quick Start Ask the assistant to implement the next incomplete phase of the approved plan in PLAN.md and run the relevant tests.
