What Agentless does
Agentless is an open-source project from the OpenAutoCoder organization that solves software development problems without an agent-based design. Its process has three phases. Localization narrows faults down to files, then classes or functions, then edit locations. Repair samples multiple candidate patches in diff format. Patch validation selects regression tests, generates reproduction tests, and re-ranks patches to choose one. Setup requires Python 3.11, the packages in requirements.txt, and an OpenAI API key. A v1.5.0 release provides SWE-bench Lite and Verified run artifacts. The project is released under the MIT license, and the page states no pricing or specific target audience.
