Nodecode

Nodecode is an AI agent running in Common Lisp that rewrites its own code while it executes.

Nodecode is an AI agent that runs as one process in SBCL, a Common Lisp system. The model evaluates Lisp in the running program to add tools and rewrite itself on the fly. It supports various providers speaking openai-completions, openai-responses, anthropic, or google dialects. Users can interact with it through terminals, browser tabs, phone links, and bots in Discord, Telegram, and Slack. Its features are modularized into cells, which are folders that teach it new skills, integrations, and tools.
