elysia

Why we included this project

Elysia takes a different route to tool use in agents. Instead of handing a model every function up front, it organizes tools into a decision tree, and a decision agent at each node picks the next step based on the current context and what has happened so far. That keeps retrieval-heavy agents from spraying tool calls at everything in sight. It comes with prebuilt tools for querying Weaviate clusters, though you can also register your own tools as async Python functions. The same codebase ships a web app with a FastAPI backend, so non-developers can run queries through a browser interface rather than the terminal.
