-- 📝 **From GitHub**. You can start Open SWE tasks directly from GitHub issues simply by adding a label `open-swe`, or `open-swe-auto` (adding `-auto` will cause Open SWE to automatically accept the plan, requiring no intervention from you). See the ['From GitHub' page](https://docs.langchain.com/labs/swe/usage/github) in the docs for more information.

For enhanced performance on complex tasks, use `open-swe-max` or `open-swe-max-auto` labels which utilize Claude Opus 4 for both planning and programming.
