 Pi auto-discovers the extension from this location via the `pi.extensions` entry in `package.json` — no settings.json config is needed. On load it emits a TUI notification `Pygienium loaded. Run /pygienium-help for available checks and flags.` (only when a dialog-capable UI is available).
 
+## Configuration
+
+Pygienium reads its chat-rendering style from pi's `settings.json` (`~/.pi/agent/settings.json`) under a `pygienium` key:
+
+```json
+{
+  "pygienium": {
+    "chatStyle": "verbose"
+  }
+}
+```
+
+| Setting | Default | Values | Description |
+| --- | --- | --- | --- |
+| `pygienium.chatStyle` | `"verbose"` | `"verbose"` \| `"compact"` | Chat rendering for sub-agent tool calls. **verbose** (piolium-style) streams each tool event live as its own chat line (`[Comments: Scanning] → bash ...` / `← (ok)`). **compact** (ralpi-style) suppresses the per-event stream and shows only the final completion message with its expandable phase tree. |
+
+No entry means `"verbose"` (the default). An unreadable or missing `settings.json` also falls back to `"verbose"`.
