Agent runtimes Open source
basis
The minimal set everything else is built from. Your host supplies the rest.
Basis is an agent harness you embed. Open a workspace, mint runs from it, read one event stream, and plug your own code into the seams. The core crate sits on Mentra with a handful of utility dependencies and carries no protocol, transport, or terminal code; the host kit, durable task layer, ACP adapter, and CLI layer on top. Any OpenAI-compatible endpoint works, Ollama and LM Studio included.
