mini-swe-agent
The 100-line AI agent that solves GitHub issues and assists in your command line.
Quick Answer
AImini-SWE-agent is an open-source AI agent framework for researchers and developers building baseline AI systems. It achieves high performance on SWE-bench, solving GitHub issues and automating command-line tasks. Best for teams doing fine-tuning or reinforcement learning on agent scaffolds. Open-source.
mini-SWE-agent is an open-source AI agent framework built by Princeton and Stanford, designed to solve GitHub issues and assist with command-line tasks. It features a minimal Python codebase, high performance on SWE-bench, and supports various local and containerized environments. The agent is open-source and compatible with many LLM backends via LiteLLM, OpenRouter, and Portkey.
mini-SWE-agent is radically simpler than other agents, including its predecessor SWE-agent, by relying solely on bash for tool use and maintaining a completely linear history for debugging and fine-tuning. This minimal design allows it to run with virtually any language model and execute actions independently in sandboxed environments.
