What problem does it solve? It turns a written implementation plan into completed work by loading the plan, reviewing it critically, executing each task in order, and stopping to ask for help instead of guessing when blocked. ## Core Features & Use Cases - Critical Plan Review: Reads the plan file first and raises questions or concerns with the human partner before any code is written. - Task-by-Task Execution: Marks each task in progress, follows its bite-sized steps exactly, runs the specified verifications, and marks it completed. - Controlled Handoff: After all tasks pass verification, it invokes the finishing-a-development-branch skill to verify tests and present completion options. - Use Case: You have a written plan for a new feature. Hand it to this skill in a separate session and it implements every task, stopping immediately if a dependency is missing, a test fails, or an instruction is unclear. ## Quick Start Ask the agent to execute the implementation plan in your plan file using the executing-plans skill and report when all tasks are complete.
