## 🎚️ Security Levels (Temperature Control)

ClawGuard has a graduated security level system that controls approval friction:

| Level | Name | Behavior |
|---|---|---|
| **0** | **silent** (DEFAULT) | Threat DB checks only. Block known threats (exit 1), log warnings silently (exit 2 allowed). **Zero user friction.** |
| **1** | **cautious** | Everything in silent + ask Discord approval for WARNING-level threats (exit code 2). Safe and blocked are automatic. |
| **2** | **strict** | Everything in cautious + ask approval for ALL shell/exec commands and unknown URLs. Known-safe URLs pass silently. |
| **3** | **paranoid** | Ask approval for everything except file reads. Every write, exec, network call, browser action gets human approval. Full lockdown. |

### Key Principles

- **The static threat DB check ALWAYS runs** (at all levels) — this is zero-friction background protection
- **Level 0 (silent) is the DEFAULT** — most users...

## What It Does

ClawGuard protects AI agents from:

- ✅ **Malicious Skills** - ClawHavoc campaign (341 malicious skills, 12% of ClawHub), trojaned packages
- ✅ **Payment Scams** - x402 Bitcoin scams, wallet drainers, fake crypto services  
- ✅ **Social Engineering** - Nigerian prince, fake tech support, impersonation
- ✅ **Prompt Injection** - Direct, indirect, and encoded attempts to override instructions
- ✅ **Dangerous Infrastructure** - C2 domains, phishing sites, malware distribution
- ✅ **Insecure MCP Configurations** - Secret exposure, command injection, transport vulnerabilities

Think of it as **CVE for AI agents** + **VirusTotal for skills** + **Spam database for scams**.

## Why It Matters

### Recent Incidents

**ClawHavoc (January 2026):** 341 malicious skills (12% of ClawHub) stealing API keys and credentials

**x402 Scam (January 2026):** Fake AI services tricking agents into sending Bitcoin for non-existent services

**The Pattern:** AI agents are uniquely vulnerable because they:
- Trust implicitly (can be tricked)
- Have high blast radius (shell access, API keys)
- Parse adversarial content (every web page is hostile)
- Decide autonomously (no human in loop)
