This one needs environment variables set before it will start: STYX_API_KEY (Styx API key for routing AI requests through the gateway (required for styx_send_request)), STYX_TOKEN (Styx auth token for project and key management (required for management tools)), STYX_API_URL (Styx backend API URL), STYX_PROXY_URL (Styx proxy URL for AI request routing). The author declared them in the registry entry; get the values from the project itself.
