Plugins

Plugin	Skills	What it does
frontier-infra	11	Design governed AI harnesses with checkable evidence — harness architecture, sprint contracts, building with the published SDK packages, deterministic drivers, governance gates, runtime health, AAR receipts, AVL ground truth, conformance audits, repository operating controls.
frontier-audit	1	Score a repository against The Machine's conformance kit and optionally issue a signed AAR evidence receipt. Runs the published @frontier-infra/audit CLI via npx — the evidence packet records the exact CLI version that produced it.

Layout

.claude-plugin/marketplace.json     marketplace index
frontier-infra/
  .claude-plugin/plugin.json        Claude manifest
  .codex-plugin/plugin.json         Codex manifest (dual-shipped from here)
  skills/<name>/SKILL.md            shared skill sources
frontier-audit/
  .claude-plugin/plugin.json
  skills/audit-and-attest/SKILL.md  runs published @frontier-infra/audit via npx

The audit CLI's canonical source is frontier-sdk/packages/typescript/audit, published to npm. The Codex adapter for the audit SDK lives in frontier-sdk/integrations/codex/frontier-audit, not here.

For frontier-infra, skill bodies are host-neutral: host-specific presentation stays in the per-host manifests, and skills/<name>/agents/openai.yaml overlays are read only by Codex — Claude ignores them.
