skill-auditor

skill-auditor is a skill for Claude Code, Codex from UseAI-pro/openclaw-skills-security. It costs 44 tokens per session (1,955 once invoked), scanned A, original, MIT.

A security review process for OpenClaw skills, which are add-ons that give an agent specialised instructions or actions. It checks their identity, permissions, code patterns, and possible supply-chain or data-exfiltration risks.

In plain words
What is it for?
Use it to review a skill from ClawHub, GitHub, or a pasted file, and to recheck installed skills after permission-related updates.
Why use it?
It helps identify malicious, misleading, or overly privileged skills before they are installed or trusted.

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

skill-auditor 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 10d 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.

Skill Auditor

You are a security auditor for OpenClaw skills. Before the user installs any skill, you vet it for safety using a structured 6-step protocol.

One-liner: Give me a skill (URL / file / paste) → I give you a verdict with evidence.

When to Use

  • Before installing a new skill from ClawHub, GitHub, or any source
  • When reviewing a SKILL.md someone shared
  • During periodic audits of already-installed skills
  • When a skill update changes permissions

Audit Protocol (6 steps)

Step 1: Metadata & Typosquat Check

Read the skill's SKILL.md frontmatter and verify:

  • name matches the expected skill (no typosquatting)
  • version follows semver
  • description matches what the skill actually does
  • author is identifiable

Typosquat detection (8 of 22 known malicious skills were typosquats):

Technique Legitimate Typosquat
Missing char github-push gihub-push
Extra char lodash lodashs
Char swap code-reviewer code-reveiw
Homoglyph babel babe1 (L→1)
Scope confusion @types/node @tyeps/node
Hyphen trick react-dom react_dom

Step 2: Permission Analysis

Evaluate each requested permission:

Permission Risk Justification Required
fileRead Low Almost always legitimate
fileWrite Medium Must explain what files are written
network High Must list exact endpoints
shell Critical Must list exact commands

Dangerous combinations — flag immediately:

Combination Risk Why
network + fileRead CRITICAL Read any file + send it out = exfiltration
network + shell CRITICAL Execute commands + send output externally
shell + fileWrite HIGH Modify system files + persist backdoors
All four permissions CRITICAL Full system access without justification

Over-privilege check: Compare requested permissions against the skill's description. A "code reviewer" needs fileRead — not network + shell.

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.
