J-Rig seven-layer binary eval CLI for Claude Skills — the `j-rig` command: package integrity, trigger/functional/regression/baseline scoring, optimizer, and rollout-gate evidence. Self-contained (bundles the internal eval engine).

Skill Refiner — the eval-guided SKILL.md improvement loop, delivered as a thin wrapper over the published @intentsolutions/refiner CLI with a 3-layer cost-tiered hook architecture (sinker/line/hook)
