Community Interventions

An intervention handler is a composable control layer that intercepts agent lifecycle events and returns typed decisions — proceed, deny, guide, confirm, or transform. Handlers are registered via the interventions option in agent configuration and evaluated in order, with short-circuiting on deny or guide actions. See Interventions for the full concept and built-in handlers.

The SDK ships reference handlers like Cedar Authorization, Steering, and Human-in-the-Loop. The packages below are community-built intervention handlers you can install and attach to an agent.
