Environment variables
  • T3RNEL_SESSION_MODEauto (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_TIMEOUT_MSHow long a single tool call may take before it fails rather than hanging the client.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
