Jido

Based on pure functional design with cmd/2, ensuring deterministic state transformations and easy testing without processes, as highlighted in the README's core loop and separation of state from effects.

Seamlessly built on GenServer with built-in supervision, parent-child hierarchies, and fault tolerance, leveraging BEAM's concurrency model for reliable production deployment, as shown in the runtime integration features.

Directives like Emit and Spawn explicitly describe side effects, separating them from state logic, which improves testability and maintainability, with typed directives covered in the guides.

Supports composable plugins for reusable capabilities and multiple execution strategies like FSM, allowing customization without modifying core agent logic, as detailed in the plugins and strategies documentation.
