About
The planner-exec skill automates the implementation phase of a development plan by reading .plan.md files and orchestrating a subagent to perform the actual coding tasks. It ensures project integrity by verifying that prerequisite plans are completed, managing status updates in PROGRESS.md, and optionally handling repetitive tasks like git commits and updating documentation. This skill is essential for developers using a plan-first workflow who want to ensure execution remains consistent, trackable, and safe from dependency conflicts.
