+### Respawn Controller (Web Interface)
+
+The respawn controller keeps interactive sessions productive by automatically cycling through update prompts:
+
+1. Detects when session goes idle (prompt character visible, no activity)
+2. Sends configured update prompt (default: "update all the docs and CLAUDE.md")
+3. Sends `/clear` command to reset context
+4. Sends `/init` to reinitialize
+5. Repeats
+
+**Configuration via API:**
+```bash
+# Start respawn with custom config
+curl -X POST localhost:3000/api/sessions/:id/respawn/start \
+  -H "Content-Type: application/json" \
+  -d '{"config": {"idleTimeoutMs": 10000, "updatePrompt": "run tests and fix issues"}}'
+
+# Update config on running respawn
+curl -X PUT localhost:3000/api/sessions/:id/respawn/config \
+  -H "Content-Type: application/json" \
+  -d '{"updatePrompt": "refactor the API layer"}'
+```
+
+**State Machine:**
+```
+WATCHING → SENDING_UPDATE → WAITING_UPDATE → SENDING_CLEAR → WAITING_CLEAR → SENDING_INIT → WAITING_INIT → WATCHING
+```
+
