Why This Track Matters

Open SWE is deprecated, but its design remains instructive for asynchronous coding-agent systems that integrate planning, execution, and GitHub-driven workflows.

This track focuses on:

  • understanding the LangGraph-based multi-agent architecture
  • learning robust development and webhook integration patterns
  • identifying operational risks in deprecated systems
  • planning migration paths to actively maintained alternatives

04 - Usage Patterns: UI and GitHub WorkflowsHow do users trigger and manage tasks?Workflow clarity
05 - Planning Control and Human-in-the-LoopHow do plan approval controls and labels affect behavior?Better execution governance
06 - Security, Auth, and Operational ConstraintsWhat security controls are critical in this architecture?Safer operations
07 - Fork Maintenance and Migration StrategyHow do teams maintain or migrate a deprecated platform?Migration plan
08 - Contribution, Legacy Support, and Next StepsHow should teams handle legacy support and docs hygiene?Sustainable transition model

What You Will Learn

  • how Open SWE's manager/planner/programmer graph pattern works
  • how webhook and label-driven workflows coordinate asynchronous coding tasks
  • how to evaluate the risk profile of deprecated but useful codebases
  • how to design a staged migration to maintained alternatives
