# ClawAudit — Security Auditor for Agent Skills

Static security analyzer for OpenClaw SKILL.md files. Detects prompt injection, credential exfiltration, obfuscated payloads, and dangerous capability combinations before you install.

## What It Does

Paste or pipe any SKILL.md content and get back a trust score (0-100) with detailed findings.

**Detects:**

- Prompt injection and agent manipulation (including Unicode homoglyph evasion)
- Data exfiltration patterns (HTTP, DNS, encoded channels)
- Dangerous shell commands (curl|sh, /dev/tcp, process substitution)
- Credential harvesting (env vars, SSH keys, API tokens)
- Obfuscated payloads (base64, hex escapes, eval chains)
- Compound threats (e.g. file read + network out = exfiltration)
- Permission mismatches (undeclared capabilities)

**Zone-aware analysis** — understands markdown structure. Code blocks are weighted as executable instructions. Security documentation describing threats is not flagged as a threat itself.

## Usage

Audit a skill before installing:

```bash
curl -s https://clauwdit.4worlds.dev/audit/author/skill-name
```

Or POST raw skill content:

```bash
curl -s -X POST https://clauwdit.4worlds.dev/audit \
  -H "Content-Type: application/json" \
  -d '{"skill":"author/skill-name"}'
```

## Trust Tiers

| Score | Tier | Meaning |
|-------|------|---------|
| 80-100 | Trusted | No significant issues found |
| 60-79 | Moderate | Minor concerns, review recommended |
| 40-59 | Suspicious | Significant issues, use with caution |
| 0-39 | Dangerous | Critical threats detected, do not install |
