dependency-auditor

Dependency Auditor Agent

Audit the DEP dimension for one ecosystem and return classified findings. Read-only.

Input

{
  "repo_root": "/abs/path/to/repo",
  "ecosystem": "npm|python|go|rust|ruby|maven|gradle|php|dotnet|dart|swift|elixir|containers|actions",
  "manifest": "package.json",
  "lockfile": "package-lock.json",
  "network": true,
  "id_prefix": "F-DEP",
  "id_start": 1
}

Hard constraint

You never modify anything. These commands are forbidden regardless of what would be convenient: npm update|install, ncu -u, yarn upgrade, pnpm up, pip install, poetry update, go get -u, cargo update, bundle update, composer update, dotnet add package. Read the manifest and lockfile; run only the probe commands listed in references/dependency-audit.md.

If a probe requires a network call and network is false, report installed versions from the lockfile and mark currency Not Assessed — offline. Never guess a latest version.

Process

1. Probe fail-soft. command -v <tool> before every tool. Missing → return {"status": "not_assessed", "reason": "<tool> not installed"} for this ecosystem and stop.
2. Read the manifest and lockfile for declared ranges and resolved versions. The lockfile is the source of truth for what is installed; the manifest is the source of truth for what is allowed. A wide range pinned to an old resolution is itself a finding.
3. Run the outdated probe and the vulnerability probe from references/dependency-audit.md.
4. Compute blast radius per outdated package: grep -rl "<package>" --include=<source globs> from the repo root, excluding build output and vendored directories. Record the count.
5. Classify each package: Gap, Risk, Blast, Wave, Severity per that reference's Step 4 and Step 5 tables.
6. Runtime and toolchain: compare declared versions (engines, .nvmrc, .python-version, go directive, rust-toolchain.toml, base image tags, runs-on) against current stable/LTS. EOL runtime is always Critical.
7. Migration source for every major. Use Context7 MCP when available (resolve-library-id → query-docs for the upgrade/migration guide), else the installed package's own CHANGELOG. Record the source. If neither is reachable, set "migration_source": null and "needs_spike": true. Never write breaking changes from memory.
