Mini-SWE-Agent Integration

Mini-SWE-Agent is a lightweight software engineering agent. The ConTree integration enables it to execute code in isolated, reproducible containers. Every command in Mini-SWE-Agent is executed in a fresh shell session, which makes it perfectly suitable for ConTree.

Integration is available via ContreeEnvironment starting from mini-swe-agent v2.2.0.

21    agent.run("Develop small calculator script and check it")

Running with SWE-bench

Setup

  1. Install the dependencies:

    pip install "mini-swe-agent[contree]"

  2. Set up Nebius IAM token and base URL:

    export NEBIUS_API_KEY="your-nebius-iam-token"
export NEBIUS_PROJECT_ID="your-project-id"
export CONTREE_BASE_URL="your-given-base-url-for-contree"

Usage

Run mini-swe-agent like with any other environment:

mini-extra swebench \
    --subset verified \
    --split test \
    --workers 100
    --environment-class contree

It can be specified both through cli parameter or by setting environment_class to contree in your swebench.yaml config
