What problem does it solve?

This Skill guides developers in implementing context-aware I/O methods that respect cancellation signals and deadlines, preventing resource leaks and ensuring safe concurrency.

Core Features & Use Cases

• Deadline Propagation: Implements patterns to respect existing deadlines and apply default timeouts when none are set, ensuring predictable operation timing.
• Cancellation Safety: Ensures resources are released with defer cancel() and uses select statements to handle ctx.Done(), avoiding goroutine leaks.
• Use Case: When designing a network client or cleanup operation, apply these patterns to guarantee timely aborts under cancellation or timeout conditions.

Quick Start

Follow the pattern to probe ctx.Deadline(), derive timeouts with context.WithTimeout, and incorporate select statements to handle cancellations during delays or retries.
