Developed a background sub-agent task dispatching toolkit for the docker/cagent repository, focusing on enhancing orchestration efficiency and runtime resilience. The solution introduced concurrent sub-agent execution with comprehensive task lifecycle management, leveraging Go for backend and API development. To ensure safe concurrent operations, session-scoped agent identities and CAS-based status transitions were implemented, eliminating race conditions and data races. The work included a Runner interface abstraction with a LocalRuntime implementation, simplifying testing and isolating runtime concerns. Resource caps and UUID-based task identifiers were enforced to improve stability and observability, resulting in a robust foundation for scalable, reliable background task management.
