/audit-deps — Dependency Audit

Audit project dependencies for security vulnerabilities, outdated packages, and license compliance across npm and Python.

The skill, Munir (.claude/agents/dependency-auditor.md), and golden-paths/pipelines/dependency-audit.yml share one contract. The shared helper is the source of truth for discovery, severity, licences, and remediation:

golden-paths/pipelines/scripts/dependency-audit.py

Adopters copy that helper beside the workflow as .github/scripts/dependency-audit.py. Compare helper_revision when refreshing. The current helper revision is 4.

Design: AgDR-0176.

Usage

/audit-deps
/audit-deps path/to/project
/audit-deps path/to/project --ecosystem=python
/audit-deps path/to/project --language=ts
/audit-deps path/to/project --runner=osv

Path resolution

source "$(git rev-parse --show-toplevel)/.claude/hooks/_lib-read-config.sh"
source "$(git rev-parse --show-toplevel)/.claude/hooks/_lib-portfolio-paths.sh"
projects_dir=$(portfolio_projects_dir)
workspace_dir=$(portfolio_workspace_dir)
HELPER="$(git rev-parse --show-toplevel)/golden-paths/pipelines/scripts/dependency-audit.py"

Run against a managed project under workspace/<name>/, or an explicit project path. Refuse the ops-fork root when it only holds framework files.

Process

1. Detect ecosystems (manifests, not source counts)

Search the project tree. Skip node_modules, .venv, vendor, dist, build, .next, and .git.

Default: audit every detected supported ecosystem. --ecosystem= filters. --language=js|ts|python is an alias. Reject conflicting filters. --runner= must match the selected ecosystem. Report detected ecosystems that the filter excludes. Report known unsupported manifests as not scanned. A tooling-only pyproject.toml with no dependency groups is not_applicable.

Known unsupported manifests

The helper does not scan these files. It records each file in not_scanned.

Each not_scanned entry has path, ecosystem, and reason. The path is relative to the scanned root. The helper does not add a NuGet runner. Discovery uses the same walk and the same ignored directories as npm and Python.

The helper exits 3 for unsupported manifests only when both conditions are true. No npm or Python dependency set is selected for checks. A tooling-only pyproject.toml does not count, because it has no dependencies to check. No --ecosystem filter is given. The --language flag selects the same filter. A Critical finding still exits 1. Every other case keeps the normal exit code. The helper still records each file in not_scanned. The Markdown report keeps the Not scanned section. The helper keeps the coverage note. This skill and the helper use that same exit rule. A tree with no dependency manifest exits 0. The helper adds the note no dependency manifests found.

The CI template starts a scan only when it finds an npm or Python manifest. Run the helper directly for a tree that has only unsupported manifests.

2. Invoke the shared helper

python3 -I "$HELPER" "$PROJECT_PATH" \
  ${ECOSYSTEM:+--ecosystem="$ECOSYSTEM"} \
  ${LANGUAGE:+--language="$LANGUAGE"} \
  ${RUNNER:+--runner="$RUNNER"} \
  --json-out /tmp/dep-audit.json \
  --md-out "$projects_dir/<name>/quality/dependency-audit-$(date -u +%Y-%m-%d).md"

Use a trusted interpreter. Do not put the audited checkout on PYTHONPATH.

3. Vulnerability scan

Python inventory is data-only. Parse lockfiles and pinned requirements as data. Never run Poetry, uv, Pipenv, build backends, or checkout plugins.

4. Severity mapping

Unknown findings need manual triage. They stay visible in totals.

5. Outdated packages

• npm: npm outdated --json
• Python: compare exact pins with version-specific public PyPI metadata via packaging==25.0

Recommend updates through the project's package manager and lockfile workflow. Never emit npm update for a Python package.

6. Licence compliance

Preserve each package's exact version, metadata source, and raw claim.

Allowed (exact SPDX): MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause, ISC, CC0-1.0, 0BSD, Unlicense

Restricted (require review, current SPDX): GPL-2.0-only, GPL-2.0-or-later, GPL-3.0-only, GPL-3.0-or-later, LGPL-2.0-only, LGPL-2.0-or-later, LGPL-2.1-only, LGPL-2.1-or-later, LGPL-3.0-only, LGPL-3.0-or-later, AGPL-3.0-only, AGPL-3.0-or-later, MPL-2.0, CDDL-1.0, CDDL-1.1

Banned: UNLICENSED, Proprietary

Pending review (not banned): Unknown, missing metadata, compound SPDX expressions, deprecated identifiers pending remapping, classifier-only claims without an exact SPDX id.

Pending review still blocks licence clearance. Unknown never becomes allowed by default.

7. Mixed repository report

Produce one report. Include per-directory dependency sets and per-ecosystem sections. Name every ecosystem and manifest. Combine severity totals across ecosystems. Deduplicate by ecosystem, package name, version, and advisory identity. Keep every affected manifest path.

8. Exit codes

The helper exits 3 for unsupported manifests only when both conditions are true. No npm or Python dependency set is selected for checks. A tooling-only pyproject.toml does not count, because it has no dependencies to check. No --ecosystem filter is given. A Critical finding still exits 1. Every other case keeps the normal exit code. The not_scanned list, the Not scanned section, and the coverage note stay. WARN or incomplete coverage does not install tools automatically. Print per-ecosystem install advice.

9. Install advice (missing tools)

npm          — install Node.js + npm for the project
pip-audit    — pip install pip-audit==2.10.0 packaging==25.0
               (trusted env only; see golden-paths/pipelines/scripts/dependency-audit-tools.lock.json)
OSV fallback — no extra install. Needs network to api.osv.dev

Output

Write the markdown report under projects/<name>/quality/ when a portfolio project name is known. Print the JSON summary on stdout.
