30-SECOND BRIEF
What it does—and when it fits
Supply Chain Risk Auditor is Trail of Bits' measured dependency-audit workflow for npm, PyPI, and Go projects. Deterministic collectors inspect direct and lockfile dependencies for advisories, abandonment, publisher concentration, and install scripts before human interpretation is added.
INSTALL BY AGENT
Choose your Agent
Paths come from official Agent docs or the universal installer behind skills.sh. Compatibility still follows this Skill's record.
.claude/skills/supply-chain-risk-auditor/~/.claude/skills/supply-chain-risk-auditor/Use project scope for team sharing and personal scope across repositories. The installer defaults to project scope; add -g for personal scope.
npx skills add trailofbits/skills --skill supply-chain-risk-auditor --agent claude-codeClaude Code discovers custom Skill folders automatically at project or personal scope.

A practical workflow
Collect dependency evidence
Measure supported manifests and lockfiles instead of estimating from memory.
Separate unknown from clean
Mark unavailable criteria as unassessable rather than silently passing them.
Prioritize remediation
Add verified upgrade paths and replacement candidates to the factual report.
THE TRADEOFFS
Advantages and tradeoffs
Notable strengths
- Deterministic scripts preserve the datum behind each verdict.
- Refuses to treat missing measurements as clean results.
Limitations
- Does not fully parse yarn.lock, pnpm-lock.yaml, poetry.lock, or unsupported ecosystems.
- Repository health and advisory data can be incomplete, delayed, or unavailable without authentication.
BEST FIT
Who it is for
Security teams reviewing third-party dependency exposure
Engineering leads assessing a dependency tree before release or engagement
BEFORE YOU USE IT
Risks to review before use
Registry and repository metadata exposure
Collection makes external requests for project dependency names and versions. Confirm that package metadata may leave the environment and keep private registry credentials scoped.
SECURITY
What the permission profile means
- Keep collector output outside the audited repository unless explicitly requested.
- Label replacement suggestions as judgment, not measured fact.
Not a security certification. External ratings are attributed references. SkillSignal has not independently executed or security-reviewed this Skill.
