What problem does it solve? Written implementation plans often go stale or get executed inconsistently when an AI session improvises instead of following the plan. This Skill enforces disciplined execution of a pre-written plan in a separate session, with critical review up front and verification after every task. ## Core Features & Use Cases - Critical Plan Review: Loads the plan file, identifies questions or concerns, and raises them with the human partner before writing any code. - Task-by-Task Execution: Tracks each task with TodoWrite, follows bite-sized steps exactly, and runs the verifications specified in the plan. - Stop-and-Ask Guardrails: Halts execution on blockers, unclear instructions, or repeated verification failures instead of guessing. - Use Case: You have a detailed implementation plan produced in a planning session. Hand it to a fresh session with this Skill so every task is executed in order, verified, and finished through the development-branch completion workflow. ## Quick Start Execute the implementation plan in docs/plans/feature-x.md task by task, verifying each step and stopping to ask if anything is blocked.
