supply-chain SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
supply-chain from nitinjain999/platform-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Secure the software supply chain from source to running container. Covers Cosign keyless image signing (Sigstore/Rekor), SBOM generation and attestation (Syft), vulnerability scanning with severity gates (Trivy/Grype), SLSA Level 2 provenance, and Kyverno/OPA admission enforcement. All open-source, no license cost. Use when asked to "sign my image", "generate an SBOM", "scan for CVEs", "attest build provenance", "enforce image signatures in Kubernetes", or "implement SLSA".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Secure the software supply chain — from the build pipeline to running containers. --- ## Interactive Wizard (fires when no arguments are provided) When invoked with no arguments, ask before proceeding: **Q1 — Mode?** ``` What do you need? 1. audit — review an existing CI/CD pipeline for supply chain security gaps 2. sign — set up keyless image signing with Cosign (Sigstore/Rekor, no key management) 3. sbom — generate and attest an SBOM with Syft 4. scan — add a CVE vulnerability gate with Trivy or Grype 5. enforce — write a Kyverno policy to block unsigned images at admission 6. slsa — generate a SLSA Level 2 provenance workflow Enter 1–6 or mode name: ``` **Q2 — Context** (after mode selected, one at a time): - **audit**: `Paste your GitHub Actions workflow file(s) or describe your current CI/CD pipeline:` - **sign**: `Which container registry? (ECR / GHCR / Docker Hub / other):` - **sbom**: `Which image and registry? (e.g. ghcr.io/org/image):` - **scan**: `Which scanner preference? Trivy (recommended) or Grype — or no preference:` - **enforce**: `Which registry or image prefix should the policy cover? (e.g. ghcr.io/myorg/*):` …

How to install
mdr add nitinjain999/platform-skills/supply-chain@sha256:c49bb140c0e1977eThe line at the top of this page pins the label git:20261018.90b97a9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
