Show HN: Flatagents: State machine orchestration with stateless LLM agents (github.com)

This is a declarative orchestration framework for stateless short-lived LLM agents.

Agents are orchestrated by hierarchical state machines (HSMs).

The HSMs and agents are defined in YAML, with hooks and webhooks for additional functionality.

* FlatAgent: A single LLM call: model + prompts + output schema.

* FlatMachine: A state machine that orchestrates multiple agents, actions, and state machines.
