Past that fork, it exists to stop three more specific failures: a spec written to avoid doing the discovery work, a features table with no objective above it, and a document that can start work but never says how to stop it. ## Files this skill drives - [../../templates/definition/prd.md](../../templates/definition/prd.md), the primary artifact, run from section 0 (the one-read summary) through section 13 (companion documents), then the sign-off block …
