Autonomous agent framework for Elixir, Jido addresses the complexity of building distributed, autonomous multi-agent systems. It formalizes agent patterns atop OTP GenServer, enabling developers to create dynamic workflows with deterministic logic and enhanced testability. The framework provides a structured approach to state management, side-effect handling, and inter-agent communication, streamlining the development of complex agent-based applications.

How It Works

Jido employs a pure functional agent architecture inspired by Elm/Redux. Agents are immutable data structures processed via a core cmd/2 function. This function accepts an action, transforms the agent's state immutably, and outputs a set of "directives" that describe external effects. These directives are then interpreted by an OTP runtime (AgentServer), ensuring that state changes are pure data transformations and side effects are explicitly managed, leading to predictable and testable agent behavior.

Quick Start & Requirements

• Installation: Add {:jido, "~> 2.0"} to mix.exs, define a Jido instance module, and integrate it into your application's supervision tree.
• Prerequisites: Elixir 1.17+ and Erlang/OTP 26+.
• Links: Official documentation is available at https://hexdocs.pm/jido. Further resources, demos, and the project repository can be found at https://agentjido.xyz and https://github.com/agentjido/jido.

Highlighted Details

• Immutable Agent Architecture: cmd/2 operation ensures pure state transformations and explicit directive generation.
• Schema-Validated State: State schemas are validated using NimbleOptions or Zoi for data integrity.
• Directive-Based Effects: Formalizes external interactions (e.g., Emit, Spawn, Schedule) separate from state updates.
• OTP Runtime Integration: Features an AgentServer for production deployment, supporting hierarchy tracking, signal routing, and instance-scoped supervision for multi-tenancy.
• Composable Skills: Enables reusable agent capabilities with isolated state and lifecycle hooks.
• Execution & Orchestration: Supports various execution strategies (Direct, FSM) and plan-based multi-agent orchestration.
