Mistral Releases Vibe CLI Coding Agent Open-Source
Mistral released Vibe, an open-source CLI coding agent, today alongside Devstral 2, publishing the Apache-2.0 licensed source code. The agent is implemented in Python using Pydantic and Rich/Textual, with core prompts extracted into Markdown and individual tool prompt files (bash, grep, read_file, write_file, etc.). Developers can inspect and extend the runnable Python tools and prompts; the author tested it generating a three.js Space Invaders demo.
