It iteratively builds harnesses tailored for effective fuzzing through tool-assisted reasoning — all without manual intervention. OverHAuL's goal is to make fuzzing accessible and immediate, reducing friction and accelerating the path to safer software.\n\n## Installation\n\n### Dependencies\n\n- Python \u003e=3.10\n- [uv](https://docs.astral.sh/uv/)\n\n### Installation Steps\n\n1. Clone the repository and cd into it:\n\n    ```bash\n    git clone https://github.com/kchousos/overhaul.git;\n    cd overhaul\n    ```\n\n2. Create a virtual environment (optional):\n\n    ```bash\n    python3.10 -m venv .venv;\n    source .venv/bin/activate # for bash\n    ```\n\n3. Install the project:\n\n    ```bash\n    uv pip install .\n    ```\n\n## Usage\n\n1. Add an OpenAI API key in `.env`, such as:\n\n    ```bash\n    # cat .env\n    OPENAI_API_KEY=\u003cAPI-key-here\u003e\n    ```\n    \n    Or export it as an environment variable:\n\n    ```bash\n    export OPENAI_API_KEY=\u003cAPI-key-here\u003e\n    ```\n\n2. Execute the main script:\n\n    ```bash\n    overhaul \u003crepo-link\u003e\n    ```\n\nThe cloned repo with the newly generated harness can be found in the `output/` directory.\n\n### Command-Line Options\n\n```\n$ overhaul --help\nusage: overhaul [-h] [-c COMMIT] [-m MODEL] [-f FILES [FILES ...]] [-o OUTPUT_DIR] repo\n\nGenerate fuzzing harnesses for C/C++ projects\n\npositional arguments:\n  repo                  Link of a project's git repo, for which to generate a harness.\n\noptions:\n  -h, --help            show this help message and exit\n  -c COMMIT, --commit COMMIT\n                        A specific commit of the project to check out\n  -m MODEL, --model MODEL\n                        LLM model to be used. Available: o3-mini, o3, gpt-4o, gpt-4o-mini, gpt-4.1, gpt-4.1-mini\n  -f FILES [FILES ...], --files FILES [FILES ...]\n                        File patterns to include in analysis (e.g. *.c *.h)\n  -o OUTPUT_DIR, --output-dir OUTPUT_DIR\n                        Directory to clone the project into. Defaults to output\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkchousos%2Foverhaul","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkchousos%2Foverhaul","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkchousos%2Foverhaul/lists"}
