mini-swe-agent is a radically simple Python-based agent from the Princeton and Stanford team behind SWE-bench that uses only bash as its tool, maintains a completely linear message history, and executes each action via independent subprocess.run calls. Despite being roughly 100 lines of core agent code, it scores over 74% on SWE-bench verified and is used by organizations including Meta, NVIDIA, IBM, and Anyscale.
- The core design argument is that as language models grow more capable, elaborate tool scaffolds become unnecessary and the LM itself should drive the shell
- Supports sandboxed deployment via docker, podman, singularity, bwrap, and others; installable from PyPI via uvx, pipx, or pip
