cve-audit

cve-audit is a skill for Claude Code, Codex from runxhq/runx. It costs 35 tokens per session (1,421 once invoked), scanned A, original, Apache-2.0.

A read-only check of exact npm package versions against OSV, a public database of known software vulnerabilities. It uses a fixed package-lock.json file and records evidence that can be replayed and reviewed.

In plain words
What is it for?
Reviewing dependencies before a release, finding advisories affecting locked npm versions, and producing evidence for security review or vulnerability triage.
Why use it?
It avoids misleading results from broad version ranges and distinguishes missing vulnerability data from proof that a package is safe.

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

cve-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.

The scan reads SKILL.md. This mod also ships 2 executable files (core.mjs, tests/core.test.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Dependency audit

Check the dependencies a project actually declares against OSV. Start with a local package-lock.json, npm-shrinkwrap.json, pnpm-lock.yaml or Cargo.lock. The default reads that file through native admission, reuses sbom-generate for inventory interpretation, and looks up exact registry package versions. It returns advisory summaries, affected coordinates, source identity and coverage. It never installs dependencies or executes the project's code.

Use this before release review or vuln-triage. Use sbom-generate when the job is an inventory or CycloneDX document; use vuln-triage to decide exposure, priority and remediation from findings already available. A database match is evidence about a package version, not proof that an application is exploitable.

Composes

  • sbom-generate#inventory-file
  • sbom-generate#inventory-source
  • sbom-generate#make
  • web-fetch#web-fetch

Choose the evidence you already have

For an ordinary local audit, supply path relative to the authorized workspace. repo_root selects that workspace root; lockfile_type is inferred from a conventional filename unless explicitly selected. scope defaults to all-locked. direct-production is available where the lockfile can establish it; npm lockfile version 1 and Cargo do not record it, so that selection is refused rather than guessed. These are locked declarations, not an inventory of what is currently installed.

from-inventory accepts the completed runx/sbom-generate.inventory.v1 packet. It keeps source identity, locations and coverage without reading or parsing the lockfile again. from-source accepts complete acquired text and uses the same inventory owner. from-url fetches a public npm JSON lockfile through web-fetch; its parsed inventory has canonical JSON identity, while the separate acquisition record retains the actual response-body digest and final URL. A mutable URL is an observation of those bytes, not an immutable repository revision.

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.
