In plain words
What is it for?
Use it to scan a skill, read the scanner's recommendation, report serious findings, and decide whether the skill should be installed.
Why use it?
It helps identify security and supply-chain risks in skills from ClawHub or other untrusted sources before they enter a project.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: built for openclaw.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is clawvet scan ./path-to-skill/ --format json.

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

clawvet-guard 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 1mo ago.

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.

clawvet-guard

Scan a third-party skill with ClawVet and act on its grade before letting it into a project.

Steps

  1. Find the skill. A ClawHub slug, a local folder, or a SKILL.md path.

  2. Scan it. Stage the full skill locally. Local folder and SKILL.md scans follow recognized references through nested helper files. Remote scans read only the fetched manifest and exit 1 with incomplete coverage. Code that is fetched and run, hidden, or loaded from outside the skill also blocks. Stage fixed dependencies locally, use literal references, and remove runtime downloads before relying on the gate.

    clawvet scan ./path-to-skill/ --format json
clawvet scan <skill-name> --remote --format json

    Use the installed clawvet. If it is not installed, stop and ask the user to run npm install -g clawvet. Do not fetch it with npx: a fresh fetch runs whatever version the registry serves at that moment, before anything has vetted it.

    For a pass/fail check only, --quiet exits 0 on pass and 1 on a high finding or worse.

    Every clawvet release carries npm provenance, so the tarball is signed and traceable to the GitHub Actions run that built it. npm view clawvet dist.attestations shows the attestation without installing anything. Updating is a deliberate npm update -g clawvet, so new detection rules arrive when the user chooses, after checking the attestation.

  3. Check status and coverage before the grade. If status is failed, coverage.complete is false, or local coverage is absent, do not install based on this scan. Report the coverage issues and resolve them first. Remote manifest scans do not clear a complete skill. Then read recommendation from the JSON; do not re-derive it from the score.

  4. Act on the grade using the table below.

  5. Report every critical and high finding with its title and description intact, even when the overall grade looks acceptable.

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.
