SkillGuard — Agent Security Scanner
When asked to check, audit, or scan a skill for security, use SkillGuard.
Trust Model (v0.3)
SkillGuard distinguishes between internal (trusted) and external (untrusted) skills:
- Internal skills — Skills under
~/.openclaw/workspace/skills/or~/.openclaw/workspace/claw-repos/. These are skills we authored ourselves. - External skills — Everything else (ClawHub downloads, third-party packages, etc.)
Why it matters
Internal skills legitimately use patterns like exec(), process.env.API_KEY, fetch(), and writeFile() — that's infrastructure code doing its job. Flagging those as "suspicious" creates noise that buries real issues.
For internal skills, SkillGuard uses vulnerability-focused scanning:
- ✅ Still flags: hardcoded secrets, reverse shells, pickle deserialization, unsafe YAML, actual code obfuscation, prompt injection in operational code
- ❌ Suppresses: "uses exec", "reads env vars", "makes HTTP requests", "writes files", "references private keys" (in wallet tools), "uses sudo" (in setup scripts), behavioral compound signatures
For external skills, full paranoid threat-model scanning applies — every pattern is treated as potentially malicious.
Overriding trust
Use --untrusted to force external mode on an internal skill:
node src/cli.js scan /path/to/skill --untrusted
Commands
Scan a local skill directory
node /home/claw/.openclaw/workspace/skillguard/src/cli.js scan <path>
Scan with compact output (for chat)
node /home/claw/.openclaw/workspace/skillguard/src/cli.js scan <path> --compact
Check text for prompt injection
node /home/claw/.openclaw/workspace/skillguard/src/cli.js check "<text>"
Batch scan multiple skills
node /home/claw/.openclaw/workspace/skillguard/src/cli.js batch <directory>
Scan a ClawHub skill by slug
node /home/claw/.openclaw/workspace/skillguard/src/cli.js scan-hub <slug>
Score Interpretation
- 80-100 ✅ LOW risk — safe to install
- 50-79 ⚠️ MEDIUM — review findings before installing
- 20-49 🟠 HIGH — significant security concerns
- 0-19 🔴 CRITICAL — do NOT install without manual review
Output Formats
- Default: full text report
--compact: chat-friendly summary--json: machine-readable full report--quiet: score and verdict only
