• Metrics queried from Datadog and forecasts from Toto become typed state.
• A model, such as TypeSafe AI's Jev , recommends an action, and Reflex commits it only if it passes the guards and invariants you declared.
• Application supplies typed state ↓ Judge recommends an action ↓ Executor checks legality, guards, and invariants ↓ Verified state transition ↓ Optional effects perform external work When to use it Reflex fits control loops where the right action depends on changing conditions, but execution must obey fixed constraints.
• Open, probe, or close based on service health, while enforcing cooldowns and probe limits.
• Choose which request gets capacity next, while enforcing resource limits.
