# Jido

An autonomous agent framework for Elixir that models agents as immutable state, actions that transform that state, signals that route events, and directives that describe effects for the runtime to execute.

Jido is an autonomous agent framework for Elixir, built for distributed, fault-tolerant workflows and multi-agent systems on top of OTP and supervision trees. Agents are immutable data structures with a single command function; actions do the work and transform agent state; signals route events into the system; and directives describe effects, such as outbound messages, for the runtime or an integration layer to carry out, keeping the agent's own decision logic pure and explicit.

AI is optional: the core package provides only the agent architecture and runtime, and a companion package adds model integration when it is needed. Other companion packages in the ecosystem provide an HTTP client for LLM APIs, composable validated actions with AI tool integration, and a CloudEvents-based message envelope for routing and pub/sub messaging.

It is written in Elixir and licensed under Apache 2.0.
