PolicyEngine

Represents a policy engine resource within the AgentCore Policy system. Policy engines serve as containers for grouping related policies and provide the execution context for policy evaluation and management. Each policy engine can be associated with one Gateway (one engine per Gateway), where it intercepts all agent tool calls and evaluates them against the contained policies before allowing tools to execute. The policy engine maintains the Cedar schema generated from the Gateway's tool manifest, ensuring that policies are validated against the actual tools and parameters available. Policy engines support two enforcement modes that can be configured when associating with a Gateway: log-only mode for testing (evaluates decisions without blocking) and enforce mode for production (actively allows or denies based on policy evaluation).
