Before you write any code for a multi-step feature, this generates a comprehensive implementation plan broken into 2-5 minute tasks following strict TDD workflow. Each task includes exact file paths, complete code snippets, test commands with expected output, and commit messages. It assumes you're a skilled dev who knows nothing about the codebase or domain, so it documents everything. Plans get saved to `docs/plans/` and you can either execute them with subagents in the same session or hand off to a parallel session using the executing-plans skill. The granularity is aggressive: write test, run test, implement, run again, commit are separate steps. Useful when you have clear requirements but need to enforce disciplined incremental development.
