Dependency Audit
Find the risky dependencies before they find you. No signup required.
Prerequisites
- None. Pure Claude Code. Uses the project's own package manager if available
(
npm audit,pip-audit,go list), and reasons about the manifest otherwise.
Trigger
- "Audit my dependencies"
- "Any risky packages in this repo?"
- "Check for outdated / vulnerable deps"
Workflow
- Detect the ecosystem(s) by manifest:
package.json/ lockfile → npm/pnpm/yarnrequirements.txt/pyproject.toml→ pipgo.mod→ Go ·Cargo.toml→ Rust ·Gemfile→ Ruby
- If the toolchain is installed, run the native auditor and parse it:
npm audit --json·pip-audit -f json·go list -m -u all·cargo auditIf not installed, fall back to inspecting the manifest directly.
- Flag each dependency against these risk classes:
| Risk | Signal |
|---|---|
| Known vulnerability | Reported by the native auditor (CVE/advisory) |
| Unpinned | *, latest, or no lock entry — non-reproducible builds |
| Wide range | ^/~ on a 0.x package (any minor can break) |
| Badly outdated | Several majors behind current |
| Abandoned | No release in a long time / archived upstream |
| Heavy / duplicate | Large transitive tree or two versions of the same lib |
Rank by severity (vulnerabilities first), and give the concrete bump/replace action.
Output:
## Dependency Audit — package.json (+ lockfile)
**3 vulnerable, 2 unpinned, 1 abandoned**
### Vulnerabilities
- `lodash@4.17.11` — prototype pollution (high). Bump to ≥ 4.17.21.
- `axios@0.21.0` — SSRF (moderate). Bump to ≥ 1.6.0 (note: v1 has breaking changes).
### Hygiene
- `left-pad: "*"` — unpinned; pin to an exact version.
- `request@2.88` — package is deprecated/abandoned; migrate to `undici` or `fetch`.
- `moment@2.29` — large + in maintenance mode; consider `date-fns` / `Temporal`.
### Suggested commands
npm i lodash@^4.17.21 axios@^1.6.0
npm rm request
