What problem does it solve? It turns a written implementation plan into completed work by executing each task in order, running the specified verifications, and stopping to ask for help instead of guessing when blocked. ## Core Features & Use Cases - Critical Plan Review: Loads the plan, reviews it critically, and raises concerns with the human partner before any code is written. - Step-by-Step Execution: Marks each task in progress, follows the plan's bite-sized steps exactly, and runs the specified verifications before marking tasks complete. - Defined Stop Conditions: Halts execution on blockers, unclear instructions, or repeated verification failures and asks for clarification rather than guessing. - Use Case: After a planning session produces an implementation plan, hand it to this skill in a separate session to execute all tasks, then finish the development branch with tests verified. ## Quick Start Ask the agent to execute the implementation plan in docs/plans using the executing-plans skill and report when all tasks are complete.
