# ship-milestone Drive one milestone through the full 10-phase TDD lifecycle — contract, tests, fixtures, RED baseline, implementation, GREEN, integration, quality, and a post-implementation simplify pass — and finish with the work committed on a reviewable branch stack. Assumes a project set up with the docs-cli + skills ecosystem (see `project-foundation` / `create-milestones`). If the target milestone's task plan and log do not exist yet, **Step 0** creates them following the `create-milestones` conventions before the TDD steps begin. ## Requirements Required tooling: - [`docs-cli`](https://github.com/ArtRichards/docs-cli) **v1.2.0 (M7+)** for the `Lifecycle:` controlled-vocab field and expanded role vocab; **v1.3.0 (M8+)** for `docs new --body-from -|<path>`. Companion skills (sub-agents invoke them by name): - `create-milestones` — read by Step 0's milestone-creation agent for conventions when scaffolding a missing task plan. - `docs` (the docs-cli skill) — used by every sub-agent for doc lifecycle and validation. - `sync-and-commit` — called by each implementation agent at the end of its step (after fresh-eyes review feedback is applied). - `simplify` — called by the Step 3 simplify agent. - `code-review` (built-in) — optional, available to fresh-eyes review agents. If a companion skill is missing, the sub-agent must fall back to the manual equivalent and note it in the milestone log. ## Substance lives in references/ This SKILL.md is intentionally
