 ## Quick Start
 
+> ⚠️ **OpenClaw users: enable `exec` permission first**
+>
+> Agent Reach relies on the Agent running shell commands (`pip install`, `mcporter`, `bird`, etc.). If your OpenClaw uses the default `messaging` tool profile, the Agent won't be able to run them. **Enable `exec` before installing:**
+>
+> ```bash
+> openclaw config set tools.profile "coding"
+> ```
+> Or set `"tools": { "profile": "coding" }` in `~/.openclaw/openclaw.json`. After changing it, restart the Gateway (`openclaw gateway restart`) and start a new conversation. Other platforms (Claude Code, Cursor, Windsurf, etc.) are not affected.
