uro-core
The Uro Engine core library — the embeddable, headless world-state engine.
Uro is a world-state engine: the persistent, versioned, forkable canonical record of a living fictional world. A model narrates; a fenced extractor distills that narration into a queryable world model — actors, places, factions, beliefs, open threads — that stays authoritative while the story plays over it. It tracks not only what is true but who knows it, and world state is versioned and forkable: a finished campaign's ending becomes a point in history any new campaign can continue from, branch off, or explore as a what-if.
uro-core contains all engine logic and is embeddable in any consumer — the engine only ever
sees ports (hexagonal architecture), never concrete adapters.
Install
pip install "uro-core[postgres,llm]"
The base install is the pure engine (it imports only ports). The shipped adapters live behind extras:
postgres— the bundled event store + semantic memory over PostgreSQL + pgvector.llm— the bundled LLM provider adapters (OpenAI-compatible + Anthropic).all— both.
An embedder can install the base package and supply their own adapters behind the same ports.
Runtime
The bundled store requires PostgreSQL 17 + pgvector. The reference setup runs it via Docker on host port 5433; see the project repository.
