+# Doctor
+
+`clawdis doctor` is the repair + migration tool for Clawdis. It runs a quick health check, audits skills, and can migrate deprecated config entries to the new schema.
+
+## What it does
+- Runs a health check and offers to restart the gateway if it looks unhealthy.
+- Prints a skills status summary (eligible/missing/blocked).
+- Detects deprecated config keys and offers to migrate them.
+
+## Legacy config migrations
+When the config contains deprecated keys, other commands will refuse to run and ask you to run `clawdis doctor`.
+Doctor will:
+- Explain which legacy keys were found.
+- Show the migration it applied.
+- Rewrite `~/.clawdis/clawdis.json` with the updated schema.
+
+Current migrations:
+- `routing.allowFrom` → `whatsapp.allowFrom`
+
+## Usage
+
+```bash
+clawdis doctor
+```
+
+If you want to review changes before writing, open the config file first:
+
+```bash
+cat ~/.clawdis/clawdis.json
+```
