The Python SDK runs in-process on your LLM clients (15 deterministic rules, 9 native provider families). Detection runs after each provider response; you can log, alert, or hard-stop the agent before the next call. Optional TokenSentinel Cloud (paid) adds dashboards, the Intervention Pack, and Pro calibration.
