- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### 🔒 Crabukit

Security scanner for OpenClaw skills. Prevents installation of malicious or vulnerable skills by static analysis. Integrates with Clawdex for comprehensive protection.

### Quick Start

# Safely install a skill (scans before installing)
crabukit install youtube-summarize

# Scan a local skill before installing
crabukit scan ./suspicious-skill/

# Scan an installed skill
crabukit scan /opt/homebrew/lib/node_modules/clawdbot/skills/unknown-skill

# CI mode - fail on high severity or above
crabukit scan ./my-skill --fail-on=high

# List all detection rules
crabukit list-rules

### 🔌 Clawdex Integration

Crabukit automatically integrates with Clawdex if installed:

# Install Clawdex for database-based protection
clawdhub install clawdex

# Now crabukit will:
# 1. Check Clawdex database (known 824+ malicious skills)
# 2. Run behavior analysis (zero-day detection)
# → Defense in depth!

Layered Protection:

Clawdex: Database of known-bad skills (fast lookup)
Crabukit: Behavior analysis for zero-days (static analysis)

### What It Detects

CategoryIssuesExternal DBKnown malicious skills (via Clawdex)SecretsHardcoded API keys, private keys, passwordsCode Injectioneval(), exec(), subprocess(shell=True)Shell Riskscurl | bash, rm -rf, unquoted variablesPermissionsDangerous tool requests without safety guidanceMetadataSuspicious patterns in SKILL.md descriptions

### Risk Scoring

Crabukit assigns a score (0-100) based on findings:

### Exit Codes

0 - Scan completed, no findings at or above --fail-on threshold
1 - Findings at or above threshold detected

### CI/CD Integration

# .github/workflows/security.yml
- name: Scan skill
  run: |
    pip install crabukit
    crabukit scan ./my-skill --fail-on=medium
