+# mini-swe-agent
+
+**The minimal AI software engineering agent.** Built by the Princeton & Stanford team behind [SWE-bench](https://github.com/swe-bench/SWE-bench) and [SWE-agent](https://github.com/SWE-agent/SWE-agent).
+
+## What it does
+
+`mini-swe-agent` solves GitHub issues and software engineering tasks by interacting with a computer **entirely through bash** — no custom tool implementations, no special interfaces, no complex scaffolding. Just the model, a shell, and a task.
+
+Scores **>74% on SWE-bench Verified** with a ~100-line Python agent class.
+
+## Key capabilities
+
+- 🐚 **Bash-only** — no tool-calling interface required; works with any chat-completion model
+- 🧩 **Model-agnostic** — runs on Claude, GPT-4, Gemini, and more via [litellm](https://github.com/BerriAI/litellm), OpenRouter, Portkey
+- 📦 **Sandboxed** — local, Docker/Podman, Singularity/Apptainer, bubblewrap, contree
+- 🔬 **Research-grade** — linear trajectory = perfect fine-tuning/RL data
+- ⚡ **Fast startup** — starts much faster than heavier agent frameworks
+- 🏢 **Production-adopted** — used by Meta, NVIDIA, Essential AI, IBM, Princeton, Stanford
+
+## How it works
+
+1. The agent receives a task (a GitHub issue or CLI prompt)
+2. It reasons aloud in a THOUGHT block, then issues **one bash command**
+3. The environment runs the command in a **fresh subshell** (stateless, safe)
+4. The agent observes the output and iterates until the task is solved
+
+```python
+from minisweagent.agents.default import DefaultAgent
+from minisweagent.models.litellm_model import LitellmModel
+from minisweagent.environments.local import LocalEnvironment
+
+agent = DefaultAgent(
+    LitellmModel(model_name="claude-sonnet-4-5-20250929"),
+    LocalEnvironment(),
+)
+agent.run("Write a sudoku game")
+```
+
+## Installation & usage
+
+```bash
+# Quickest — no install needed
+pip install uv && uvx mini-swe-agent
+
+# Or install permanently
+pip install mini-swe-agent
+mini  # run the CLI
+```
+
+## Benchmarks
+
+| Model | SWE-bench Verified |
+|---|---|
+| Gemini 3 Pro | 74%+ |
+| Claude Sonnet 4 | ~70% |
+| GPT-5 | ~68% |
