plan-implementing

What problem does it solve? Executing a multi-phase technical plan manually is error-prone: steps get skipped, context is lost between phases, and mismatches between the plan and the actual codebase go unnoticed. This Skill provides a disciplined workflow for implementing an approved plan phase by phase while tracking progress and verifying each stage. ## Core Features & Use Cases - Phase-by-Phase Execution: Reads the full plan, implements each phase completely, and checks off completed items directly in the plan file. - Mismatch Handling: When reality diverges from the plan, it stops, presents the expected versus actual situation, and asks how to proceed instead of guessing. - Resumable Progress: Detects existing checkmarks in a plan and resumes from the first unchecked item, trusting prior completed work. - Use Case: You have an approved refactoring plan with five phases and success criteria. Hand the plan path to the Skill and it implements each phase, runs the verification checks, and updates the plan's checkboxes as it goes. ## Quick Start Implement the approved plan at docs/plans/auth-refactor.md phase by phase, checking off completed items as you go.
