# Config Guard 🛡️

**Stop AI agents from killing themselves by editing their own config wrong.**

OpenClaw agents have full access to `openclaw.json` — the file that controls the gateway, channels, models, and tools. One bad edit and the gateway crashes. The agent goes offline. Nobody can fix it remotely.

This skill prevents that.

## The Problem

Real incidents (all from 2026-02-04, same day):

| What happened | Root cause |
|---|---|
| Gateway crashed after update | AI added unknown config fields (`auth`, `fallbacks`) |
| Model not found | AI wrote `claude-sonnet-4.5` (dots) instead of `claude-sonnet-4-5` (hyphens) |
| Telegram stopped working | Config change silently wiped the channel section |
| browser.profiles error | AI forgot the required `color` field (must be hex) |
| Plugin SDK missing | Update broke module paths, no validation caught it |

**Core truth: AI doesn't know correct config formats. It guesses. Wrong guesses crash systems.**

## What Config Guard Does

### Before config changes:
1. **Auto-backup** — `cp openclaw.json` to timestamped backup
2. **JSON syntax check** — catches malformed JSON before it hits the gateway
3. **Schema validation** — checks required fields, correct types, valid values
4. **Semantic checks** — catches AI-specific mistakes:
   - Model names with dots instead of hyphens
   - Missing required fields (browser.profiles.color)
   - Unknown top-level keys
   - Placeholder values in sensitive fields
