Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| T3RNEL_SESSION_MODE | — | — | auto (default) uses the extension when its relay socket exists and falls back to a standalone browser; extension forces the extension; standalone forces its own browser. |
| T3RNEL_SESSION_HEADLESS | — | — | Set to 1 to run the standalone browser headless. Ignored in extension mode. |
| T3RNEL_SESSION_TIMEOUT_MS | — | — | How long a single tool call may take before it fails rather than hanging the client. |
