What it does

Operate Supply Chain Toolchain is an agent skill from cyberful/cyberful. Operate Syft, Grype, Trivy, Gitleaks, Retire.js, package-manager metadata, and build evidence for advanced software-supply-chain assessment. Use for SBOM construction, dependency reconciliation, image and filesystem analysis, secret-history review, vulnerability triage, provenance gaps, release-diff analysis, and separating package presence from reachable exploitability.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `assets/supply-chain-campaign.example.json` and `assets/supply-chain-campaign.schema.json`).

It sits in Security, covering Supply chain security. It works with Trivy. 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

  • SBOM construction
  • Dependency reconciliation
  • Image and filesystem analysis
  • Secret-history review

Example prompts

  • “/operate-supply-chain-toolchain”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Generate a canonical SBOM with Syft using package and file catalogers appropriate to the artifact.
  2. Generate independent Trivy inventory/vulnerability output.
  3. Scan the canonical SBOM with Grype so inventory drift is not confused with advisory drift.
  4. Use Retire.js for shipped browser bundles and vendored JavaScript that package manifests miss.
  5. Diff inventories by package URL, coordinates, version, location, layer, and evidence source.

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

    Ships 2 files in scripts/ (Python), which the agent can run.

    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

Operate Supply Chain Toolchain loads about 1.2k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 447 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~101
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2k

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); the scripts in this folder are not scanned.

Operate Supply Chain Toolchain

Build an evidence graph from source declaration to lock resolution, restored artifact, build stage, runtime image, loaded component, advisory match, and reachable behavior. Scanner counts are intermediate data, not conclusions.

Establish artifact identity

Record commit and submodules, lockfiles, package-manager versions, build arguments, target platform, base-image digest, image digest, registry, SBOM format/schema, scanner versions, vulnerability database timestamps, ignore policy, and collection time.

Scan source trees, build outputs, container images, and deployed artifacts separately. A multistage build can remove build dependencies; vendoring, shading, static linking, plugins, or runtime downloads can add components absent from manifests.

Build and reconcile inventories

  1. Generate a canonical SBOM with Syft using package and file catalogers appropriate to the artifact.
  2. Generate independent Trivy inventory/vulnerability output.
  3. Scan the canonical SBOM with Grype so inventory drift is not confused with advisory drift.
  4. Use Retire.js for shipped browser bundles and vendored JavaScript that package manifests miss.
  5. Diff inventories by package URL, coordinates, version, location, layer, and evidence source.

Read references/supply-chain-fieldbook.md for reconciliation and high-value edge cases.

For a bounded active campaign, stage scripts/run_supply_chain_campaign.py, assets/supply-chain-campaign.example.json, and assets/supply-chain-campaign.schema.json. Replace the example paths in the workarea, set authorized, the local artifact, selected tools, run ceiling, and timeout explicitly, then execute the staged script with --workspace and --config. The orchestrator resolves only fixed Syft, Grype, Trivy, or Gitleaks command names from the trusted runtime, invokes them update-disabled with argv and no shell, and bounds streams and native output while each process runs. It never installs or updates dependencies. A missing local tool degrades that run; it must not open a network route, especially during Code Audit.

Triage vulnerabilities as hypotheses

For each candidate, establish package identity, installed versus upstream version semantics, distro backports, affected component/function, reachable entry point, attacker influence, runtime privilege, mitigating configuration, deployment exposure, and fixed-version feasibility.

Do not dismiss a finding solely because the application does not import the package directly; transitive loaders, framework auto-discovery, native linkage, and tooling invoked in CI can create reachability.

Separate secret surfaces

Run Gitleaks against current content and repository history with explicit configuration and stable output. Classify each result as live credential, revoked credential, test fixture, high-entropy non-secret, encrypted material, or unresolved. Validate only with non-mutating identity/introspection calls when appropriate; never print full values into reports.

Search build logs, image layers, package registry configuration, CI definitions, generated source maps, debug artifacts, and release bundles. Deleting a file in a later container layer does not remove it from earlier layers.

Deliver

Preserve raw SBOMs, scanner/database identity, manifest-to-runtime diffs, secret scope and provenance, triage rationale, suppressed items, unscanned artifact classes, and remediation ordered by reachable impact and supply-chain leverage. Keep inventory confidence distinct from vulnerability confidence.
