supply-chain-security

supply-chain-security is a skill for Claude Code from atretyak1985/swarmery. It costs 52 tokens per session (815 once invoked), scanned A, original, Apache-2.0.

A read-only review of how container images are built, scanned, documented, promoted, and retained. A container image is a packaged application and its runtime dependencies.

In plain words
What is it for?
It helps check image scanning, software bills of materials, immutable image digests, rollback retention, signing readiness, and provenance records in container delivery workflows.
Why use it?
It helps identify weaknesses that could allow an unsafe or untraceable image to reach deployment environments.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

supply-chain-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Audit the container image lifecycle — build through promotion — against four baseline controls (image scanning, SBOM generation, immutable digest promotion, rollback retention) and two roadmap controls (image signing, provenance attestation), producing a gap report with current-state assessments and prioritized remediation. Application code vulnerabilities belong to security-audit; pipeline YAML structure to the project's infra pack skills. Done when every baseline control has a current-state description, gap assessment, and remediation, with unsafe patterns cited by file.

Rules (never violate)

  1. Read-only audit: never install or configure scanners, or edit pipeline config, without team approval.
  2. Roadmap items (signing, provenance) are future work, never blockers.
  3. Only @sha256:... is immutable — :v1.2.3 and :main are mutable tags; never confuse them.
  4. A scanner without a blocking severity threshold is a gap — finding a scanner is not enough.
  5. CVE exemptions require a documented rationale and expiry date.
  6. Container CI/CD only — SSH device deploys and Terraform state are out of scope.

Resources

  • Read resources/gap-audit-procedure.md when running the audit: the skill-boundary scope table, the 8-step procedure with checkpoints, the gap-report template and length budgets, self-check, mistakes, escalation, worked examples, and failure modes.

How to use

What it does

Audits your CI/CD pipeline's container image lifecycle against four baseline supply-chain controls plus two roadmap controls, returning a gap report that says, per control, what you have today, whether there is a gap, and what to change — every finding cited to file:line.

When to use it

  • Does the pipeline block a build on a critical CVE, and where does the scan run?
  • Deployments reference mutable tags like :main and you want @sha256: digests.
  • "Should we sign our images?" needs a readiness answer; a newly added scanner needs its threshold, ordering, and artifact storage checked.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

supply-chain-security is a skill published in the GitHub repository atretyak1985/swarmery (7 stars, last pushed 2d ago), licensed Apache-2.0. It adds 52 tokens to every session and 815 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
