Open-source LLM workflow OS
Reyn is an LLM workflow OS. Phase transitions are constrained, validated, and replayable — predictability for production agents, not just experiments.
Reyn is a runtime engine, not just an orchestrator. Every LLM transition is gated by a JSON-schema-validated contract and a closed candidate set. The LLM decides; the OS enforces.
A Skill is a directed graph of Phases. Each Phase declares its input contract and runs to completion under a permission scope you control.
The LLM picks only from candidates the OS provides. Output is validated against the next Phase's input schema. Workspace and Events make every step replayable.
A scoped runner with a memory window, a permission scope, and a curated set of Skills it can invoke.
A directed graph plus a final-output schema. The OS routes work between Phases based on LLM decisions and validated artifacts.
Builds context, validates every output, executes Control IR ops under permission gates. Owns Workspace and Events for state and audit.
