This is the workhorse skill that takes a tracked issue and drives it from start to finish: failing test, minimal implementation, refactor under green, commit, close. It integrates the full TDD loop with automatic lifecycle skill invocations for testing, review, and refactoring unless you disable them. The workflow is opinionated about discipline (tests must fail for the right reason, code changes require a failing test first, refactors are separate commits) and enforces verification gates before allowing completion. GREEN mode is notable because it locks you into test-first mode where you implement against immutable tests without touching the test files. Works standalone or plugs into the beads issue tracker with `bd` CLI for claim/close automation and ratchet recording.
