This generates detailed implementation plans formatted as markdown files with the assumption that whoever's executing has zero context about your codebase. It's opinionated about process (DRY, YAGNI, TDD, frequent commits) and structures everything as bite-sized tasks with specific file references and testing instructions. Saves plans to a dated docs/plans directory and works best in a dedicated worktree. The philosophy here is treating the implementer like a skilled but context-free contractor who needs explicit guidance on what to touch and how to verify it works. If you're working with AI coding agents or trying to make your planning more executable by others, this creates the scaffolding to hand off work without endless back and forth.
