+
+# I Built an AI Doctor for My AI Agent
+
+**TL;DR:** My AI agent kept crashing at 3am. So I built another AI to fix it.
+
+## The Problem
+
+I run [OpenClaw](https://github.com/openclaw/openclaw), an AI agent framework, on a Mac Mini. It's great until it crashes at 3am and I wake up to a dead assistant.
+
+Traditional watchdogs just restart the process. They don't understand *why* it crashed.
+
+## The Solution: 4-Tier Self-Healing
+
+```
+Level 1: Watchdog (180s)     → Process dead? Restart.
+Level 2: Health Check (300s) → HTTP failing? Retry 3x.
+Level 3: Claude Doctor (30m) → AI diagnosis + autonomous fix 🧠
+Level 4: Discord Alert       → Human escalation
+```
+
+### The Interesting Part: Level 3
+
+When Levels 1-2 fail, the system launches **Claude Code** (Anthropic's CLI) in a tmux PTY session:
+
+```bash
+tmux new-session -d -s emergency-recovery
+tmux send-keys "claude --dangerously-skip-permissions" Enter
+tmux send-keys "Gateway is down. Diagnose and fix." Enter
+```
+
+Claude then:
+1. Runs `openclaw status`
+2. Reads system logs
+3. Identifies root cause (stale PID, port conflict, config error...)
+4. Executes fixes
+5. Verifies recovery
+
+**All logged. All auditable.**
+
+## Security Model
+
+- Isolated tmux session (no main session access)
+- Read-only config access
+- 30-minute hard timeout
+- Cleanup trap prevents orphan processes
+- Level 4 watchdog monitors Level 3
+
+## The Philosophy
+
+> "If we trust AI to write code, why not trust it to fix infrastructure?"
+
+The AI already knows how to diagnose problems — it does it every day when developers ask for help. We just gave it permission to act on its diagnosis.
+
+## Results
+
+- Recovery time: 25 seconds (vs 8+ hours waiting for human)
+- False positives: 0 (so far)
+- My sleep quality: Improved 🛌
