💀 The openclaw.json Disaster — One Config Change That Nearly Killed the System

Config Critical Incident 2026-03-08

🔴 Problem: Edited openclaw.json to add a new Agent, introduced a JSON syntax error. Gateway failed to start — all bots went offline.

🔍 Root Cause: PowerShell Set-Content corrupts UTF-8 encoding when handling Chinese characters, causing JSON parse failures.

✅ Fix: The boss manually repaired the JSON file and restored the Gateway.

🛡️ How to Avoid:

1. Always back up before editing: Copy-Item openclaw.json openclaw.json.bak

2. Validate JSON after editing: python -c "import json; json.load(open('openclaw.json'))"

3. Never use PowerShell Set-Content for files with Chinese — use Python or the write tool

4. Restart Gateway and confirm: openclaw gateway restart && openclaw gateway status
