Environment variables

  • CADENCE_API_KEY required secret Your Cadence API key. A sandbox key (sk_sandbox_…) simulates delivery end to end and reaches no handset; a live key sends real messages. Get one free at https://cadencercs.com/app.html — no card, no compliance wait.
  • CADENCE_ALLOW_IRREVERSIBLE Set to 1 to expose the three one-way-door tools: sync_google, request_verification and request_launch. They create an agent at Google that can never be deleted, and freeze the launch questionnaire. Left unset they are absent from tools/list entirely, so no model in this configuration can reach them.
  • CADENCE_API_URL Override the API host. Defaults to https://api.cadencercs.com.
