go Best Practices Audit

What it does

This skill provides a comprehensive audit system for Go codebases, focusing on idiomatic style, high-performance patterns, and concurrency safety. It moves beyond basic linting to identify structural flaws, memory leaks, and race conditions that automated tools often miss.

Why use this skill

Modern Go development (1.21+) has introduced significant changes to the standard library and language built-ins. Prompting an AI directly often results in outdated "legacy" Go patterns. This skill ensures your agent uses the latest features like slog, min/max, and clear(), while strictly adhering to Go's unique philosophy of simplicity and efficiency.

Key Features

• Concurrency Safety: Detects goroutine leaks, unprotected shared state, and improper WaitGroup usage.
• Performance Tuning: Identifies slice/map growth anti-patterns and inefficient string building.
• Modern Idioms: Enforces proper error wrapping (%w), context propagation, and standard library best practices.
• Structural Audit: Validates package organization, naming conventions, and interface design.

Expected Output

The skill generates structured feedback highlighting specific lines of code, the underlying anti-pattern, and a refactored "After" snippet implementing the corrected Go idiom.
