Skillify — The Meta Skill

Relationship to /cross-modal-review: That skill is the manual mid-flow "second opinion" gate (one model reviews work product before commit). This skill's Phase 3 below uses gbrain eval cross-modal instead — three different-provider frontier models score-and-iterate on a documented dimension list before tests cement behavior. Use /cross-modal-review for ad-hoc second opinions; use Phase 3 here when skillifying a feature.

A feature is "properly skilled" when all 11 checklist items pass. Item 3 (cross-modal eval) is informational in v1.1.0 — it does not gate the skillpack-check audit, but a missing or stale receipt is surfaced so the user knows where the gate stands.
