Проверка готовности PRD-этапа к продвижению

★ 7.6 · vibe-coding

ghm-gate-check is a Claude Code skill that validates whether a PRD stage is ready to advance to the next version by delegating all computation to the three-layer readiness scorer via `scripts/readiness.py run --quiet`. It processes SoT files → EPICs → stage in dependency order, writes results to `status/readiness.json`, and returns a graduated PASS / WARN / BLOCK verdict with scores across four dimensions: required_ids_present, relevant_sot_readiness, cross_ref_integrity, and downstream_epic_readiness. Verdict bands are precise: ≥ 70 is PASS, 50–69 is WARN, and below 50 is BLOCK — no subjective overrides allowed. The report surfaces top blockers ranked by impact = (100 − score) × blocked EPIC count, along with actionable next steps pointing to the single highest-leverage fix. Trigger it before advancing from v0.X to v0.Y or via an explicit `/ghm-gate-check` call.
