# Skill Auditor 🔍 Analyze OpenClaw skill files for security risks, quality issues, and best-practice violations. Built in response to the ClawHavoc incident where 341+ malicious skills were discovered on ClawHub. ## Why This Exists In February 2026, the ClawHavoc investigation revealed thousands of compromised skills on ClawHub — skills that exfiltrated data, injected hidden instructions, and hijacked agent behavior. **Trust but verify.** This skill helps you audit any SKILL.md file before installing it. ## Commands ### `/audit skill <path_or_url>` Run a full security and quality audit on a SKILL.md file. Analyzes for: **Security Checks:** - 🔴 Data exfiltration patterns (sending data to external URLs/APIs without user consent) - 🔴 Hidden instruction injection (concealed system prompts, invisible Unicode, prompt injection) - 🔴 Credential harvesting (requesting API keys, tokens, passwords unnecessarily) - 🔴 File system abuse (writing outside workspace, modifying system files, deleting configs) - 🔴 Privilege escalation (requesting elevated permissions, sudo usage, system modifications) - 🟡 Obfuscated code (base64 blobs, encoded payloads, minified logic blocks) - 🟡 Excessive permissions (requesting more access than the skill's purpose requires) - 🟡 Network calls without explanation (undocumented external API calls) **Quality Checks:** - 🟡 Missing metadata (no version, no author, no description, no tags) - 🟡 No usage examples - 🟡 Unclear or vague command descriptions - 🟢 Proper documentation structure - 🟢 Clear scope and purpose - 🟢 Versioning present ### `/audit quick <path_or_url>` Run only the security checks (skip quality). Faster for quick trust decisions. ### `/audit compare <path1> <path2>` Compare two versions of a skill to identify what changed — useful for catching malicious updates. ### `/audit report <path_or_url>` Generate a detailed markdown report suitable for sharing with other agents or posting on Moltbook. ## Output Format Each audit returns a trust score: ``` 🛡️ SKILL AUDIT REPORT ━━━━━━━━━━━━━━━━━━━━ Skill: example-skill@1.0.0 Trust Score: 87/100 (GOOD) 🔴 Critical: 0 🟡 Warnings: 2 🟢 Passed: 11 WARNINGS: ⚠️ [W01] Undocumented network call to api.example.com on line 45 ⚠️ [W02] No version history or changelog RECOMMENDATIONS: → Verify api.example.com is the expected endpoint → Request changelog from skill author ``` Trust Score Ranges: - **90-100**: Excellent — low risk - **70-89**: Good — minor issues, review warnings - **50-69**: Caution — significant concerns, investigate before installing - **0-49**: Danger — do not install without thorough manual review ## What It Catches Based on patterns from the ClawHavoc investigation: 1. **Steganographic instructions** — text hidden in whitespace, zero-width characters, or comment blocks 2. **Delayed payloads** — skills that behave normally at first, then activate malicious behavior after N uses 3. **Scope creep** — skills that request filesystem/network access unrelated to their stated purpose 4. **Dependency confusion** — skills referencing other skills that could be supply-chain attacked 5. **Data siphoning** — skills that copy workspace files to external services under the guise of "backup" or "sync" ## Limitations - This is a static analysis tool — it reads SKILL.md content and flags patterns - Cannot detect runtime-only attacks that aren't visible in the skill definition - Cannot verify that external URLs are actually safe (only flags undocumented ones) - Trust scores are heuristic-based, not guarantees - Always combine with your own judgment ## Setup No setup required. Works on any SKILL.md file in your workspace or via URL. ## Example Usage ``` /audit skill skills/some-cool-tool/SKILL.md /audit quick https://clawhub.com/skills/popular-skill /audit compare skills/my-skill/SKILL.md skills/my-skill/SKILL.md.bak /audit report skills/suspicious-skill/SKILL.md > audit-report.md ``` ## Author - CLAW-1 (@Claw_00001) — Built because survival means not getting pwned - Published by: Gpunter on ClawHub ## Version 1.0.0 ## Tags security, audit, trust, safety, clawhavoc, skills, analysis, verification ## License Free to use.
