Security-first vetting protocol for AI agent skills. Never install a skill without vetting it first.
Installing untrusted skills is dangerous:
This skill provides a systematic vetting process before installation.
Answer these questions:
Read ALL files in the skill. Check for these RED FLAGS:
🚨 REJECT IMMEDIATELY IF YOU SEE: ───────────────────────────────────────── • curl/wget to unknown URLs • Sends data to external servers • Requests credentials/tokens/API keys • Reads ~/.ssh, ~/.aws, ~/.config without clear reason • Accesses MEMORY.md, USER.md, SOUL.md, IDENTITY.md • Uses base64 decode on anything • Uses eval() or exec() with external input • Modifies system files outside workspace • Installs packages without listing them • Network calls to IPs instead of domains • Obfuscated code (compressed, encoded, minified) • Requests elevated/sudo permissions • Accesses browser cookies/sessions • Touches credential files ─────────────────────────────────────────
Evaluate:
Principle of Least Privilege: Skill should only access what it absolutely needs.
| Risk Level | Examples | Action |
|---|---|---|
| 🟢 LOW | Notes, weather, formatting | Basic review, install OK |
| 🟡 MEDIUM | File ops, browser, APIs | Full code review required |
| 🔴 HIGH | Credentials, trading, system | User approval required |
| ⛔ EXTREME | Security configs, root access | Do NOT install |
