SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Go developers frequently struggle with writing correct and leak-free concurrent code; this Skill provides guided patterns and practical examples to help design, review, and implement safe goroutines, channels, and synchronization primitives.

Core Features & Use Cases

  • Learn and apply best practices for goroutine lifecycles, channel direction, and proper shutdown.
  • Review code for context propagation, proper use of WaitGroup/errgroup, and avoidance of time.After in loops.
  • Use in PR reviews, pair programming, and educational scenarios to propagate reliable concurrency.

Quick Start

Implement a tiny Go example that uses context cancellation to gracefully stop a set of worker goroutines.

FAQPage Schema
How do I prevent goroutine leaks in Go code?

Prevent goroutine leaks by ensuring all goroutines exit properly via context cancellation, signal channels, or WaitGroup coordination. Analyzing your Go code helps enforce these safe concurrency patterns and avoid improper channel closures.

Why should I avoid time.After in Go concurrency loops?

Avoid time.After in loops because it creates a new timer every iteration that is not garbage collected until it fires, causing resource leaks. Safe concurrency patterns dictate using context cancellation or signal channels for loop shutdown instead.

How do I use context cancellation to gracefully stop worker goroutines?

Use context cancellation by passing a context to worker goroutines and selecting on context.Done. Implement a tiny Go example with a select statement to gracefully stop workers, ensuring all goroutines exit when the context is canceled.

What is the best way to review Go channels and synchronization primitives in a PR?

Review Go channels and synchronization primitives by checking context propagation, proper use of WaitGroup or errgroup, and channel direction. Apply safe concurrency patterns to PR audits to ensure goroutine lifecycles are managed correctly.

Can I use errgroup to coordinate goroutine shutdown in Go?

Yes, use errgroup to coordinate goroutine shutdown and propagate errors. Analyzing Go code for proper use of errgroup alongside WaitGroup ensures safe concurrency patterns and helps avoid leaks during code reviews.

Does this Skill check for improper channel closures in Go?

Yes, analyzing Go code includes checking for improper channel closures to avoid concurrency issues. It enforces safe patterns by ensuring all goroutines exit via context cancellation, signal channels, or WaitGroup coordination.
