Async Task Pattern
Implements an asynchronous task state machine to prevent gateway timeouts and handle long-running operations efficiently.
This skill provides a robust blueprint for handling backend operations that exceed 10 seconds, such as batch data processing, cross-tenant aggregation, or remote API calls. It guides developers in transitioning from blocking synchronous calls to an asynchronous trigger-and-poll pattern, effectively preventing 504 gateway timeouts, duplicate triggers, and memory leaks. The skill includes specific implementation patterns for Java/Spring backends—including thread-local context propagation—and standardized UX guidelines for frontend polling and progress visualization.
