What problem does it solve? Written implementation plans often drift during execution: steps get skipped, verifications are ignored, and blockers are silently worked around. This Skill enforces disciplined execution of a written plan in a separate session, with critical review before starting and explicit stop conditions when blocked. ## Core Features & Use Cases - Critical Plan Review: Loads the plan file, raises concerns with the human partner before starting, and creates todos for each plan item. - Step-by-Step Execution: Marks tasks in_progress, follows each bite-sized step exactly, runs specified verifications, and marks tasks completed. - OpenSpec Apply Mode: When invoked by OpenSpec Apply, executes only the accepted repository scope and returns verification evidence to the caller without auto-publishing or merging. - Use Case: You have a written implementation plan from a planning session. Hand it to this Skill in a fresh session so every task is executed in order, verified, and handed off to the finishing-a-development-branch workflow. ## Quick Start Execute the implementation plan in plan.md task by task, running each verification and stopping to ask if anything is blocked.
