## What it is
A Rust ReAct loop coordinator that implements a stateless state machine for the reasoning-and-action cycle in agent systems. It is part of the Unicity AOS/Astrid OS ecosystem, orchestrating session, identity, prompt-building, provider, and tool-routing capsules over an IPC event bus without performing inference or tool execution itself.

## Use cases
- coordinate a ReAct reasoning-and-action loop for an LLM agent
- orchestrate multiple agent capsules over an IPC event bus
- swap agent orchestration strategies like debate or chain-of-verification
- build a stateless state machine for streaming LLM turns and tool calls
- separate agent control flow from inference and tool execution

## When to choose
- you are building agents within the Unicity AOS/Astrid OS capsule model
- you want pure orchestration control flow decoupled from LLM providers and tools
- you need a Rust/WASM state machine for the ReAct cycle

## When to avoid
- you need a full agent framework with built-in LLM calls, tools, or memory
- you want a standalone agent runtime outside the AOS capsule ecosystem
- you need conversation history persistence, which lives in the session capsule

## Facets
- artifact type: library

- domain: large-language-models, developer-tools
