  • Several producer-to-runtime controls need one evidence model

What it does

Audit Software Supply Chain is an agent skill from cyberful/cyberful. Coordinate an authorized software-supply-chain audit from dependency resolution through build, artifact, release, deployment, and runtime trust. Use when several producer-to-runtime controls need one evidence model; use a narrower specialist for one pipeline, artifact, secret, infrastructure, or release mechanism.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/ci-build-provenance.md` and `references/dependency-resolution.md`).

It sits in Security, covering Supply chain security. The repository describes itself as: Cyberful is an open-source AI Red Team for discovering, exploiting, verifying, and remediating vulnerabilities. The licence is AGPL-3.0.

When your agent uses it

  • Several producer-to-runtime controls need one evidence model
  • Use a narrower specialist for one pipeline
  • Release mechanism

Example prompts

  • “/audit-software-supply-chain”

What it can do on your machine

Read from SKILL.md and the folder at commit ec598a6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Audit Software Supply Chain loads about 737 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 86 tokens; SKILL.md has 217 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~737
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Audit the Software Supply Chain

Own the end-to-end trust model and route concrete analysis to specialists.

Build the shared chain

Map source commit -> dependency resolution -> generated inputs -> build identity -> cache -> artifact -> registry -> attestation -> promotion -> deployment -> runtime. For every edge, record who can write, which identity authorizes it, how bytes are selected, and which evidence binds input to output.

Read references/dependency-resolution.md to inventory ecosystem authority and references/ci-build-provenance.md to define the shared producer-to-runtime ledger.

Route the mechanisms

  • Native SBOM, vulnerability, image, and secret evidence: operate-supply-chain-toolchain.
  • Infrastructure definitions and plans: audit-infrastructure-as-code.
  • CI, build, promotion, and release controls: audit-build-release-pipelines.
  • Model, dataset, adapter, and ML artifact provenance: audit-ai-model-supply-chain.
  • Secret custody and broker policy: audit-secrets-management.
  • Commit-to-release security deltas: analyze-release-security-diff.
  • Container and orchestration enforcement: audit-container-runtime-isolation and audit-kubernetes-policy-enforcement.

Do not repeat scanner, pipeline, IaC, or secret-review procedures here.

Reconcile evidence

Keep declaration, resolution, build inclusion, shipped presence, runtime loading, advisory applicability, and exploit reachability as separate evidence grades. Require artifact digests, tool/database versions, identity context, policy source, negative controls, and unavailable stages from every specialist.

Confirm a finding only when an untrusted or insufficiently authenticated input can alter a trusted dependency, build, release, deployment, or runtime result. Deduplicate by compromised trust edge and authority owner. Deliver the chain map, coverage ledger, confirmed breaks, unsupported assumptions, systemic leverage, remediation owner, regression proof, and residual blind spots.
