dependency-audit

dependency-audit is a skill for Claude Code, Codex from fusengine/agents. It costs 31 tokens per session (489 once invoked), scanned A, original, MIT.

A dependency vulnerability scanner that uses the audit tools for package ecosystems such as npm, Composer, pip, Cargo, Go, Swift, and Ruby. It checks installed project dependencies against known security advisories.

In plain words
What is it for?
Use it to scan lockfiles and project dependencies, classify findings by severity, suggest fixed versions, and apply supported automatic fixes.
Why use it?
It helps identify vulnerable third-party packages and shows whether an upgrade, alternative, or manual fix is needed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dependency-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

It parses each tool's output, classifies findings by severity (CRITICAL/HIGH/MEDIUM/LOW), and suggests fix versions or alternatives. With the --fix flag it applies safe auto-fixes where supported (npm audit fix, cargo audit fix) and gives manual guidance for ecosystems without auto-fix.

Out of scope: researching a single named dependency's CVE history in depth belongs to cve-research.

Dependency Audit Skill

Overview

Run dependency vulnerability checks using native package manager audit tools.

Supported Ecosystems

Ecosystem Tool Auto-fix
npm/yarn/pnpm/bun npm audit / yarn audit Yes
PHP/Composer composer audit Manual
Python/pip pip-audit / safety check Manual
Rust/Cargo cargo audit Yes
Go govulncheck ./... Manual
Swift/CocoaPods pod audit Manual
Ruby/Bundler bundle audit Manual

Workflow

  1. Detect package manager from lock files
  2. Run appropriate audit command
  3. Parse output for vulnerabilities
  4. Classify by severity (CRITICAL/HIGH/MEDIUM/LOW)
  5. Suggest fix versions or alternatives

Auto-Fix Support

When --fix flag is used:

  • npm audit fix for safe updates
  • cargo audit fix for Rust
  • Manual guidance for other ecosystems

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dependency-audit is a skill published in the GitHub repository fusengine/agents (25 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 489 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
