by Timoranjes
Professional Go code auditor for performance optimization, concurrency safety, and modern 1.21+ idioms.
- Detect and fix goroutine leaks and race conditions in concurrent code
- Optimize memory allocations by identifying slice and map growth issues
- Modernize legacy Go code to use new 1.21+ built-ins and packages

- Detect and fix goroutine leaks and race conditions in concurrent code
- Modernize legacy Go code to use new 1.21+ built-ins and packages
- terminal, file_read, network automation included
- Ready for Cursor
Sample input
Audit this Go function for performance and safety: func Process(urls []string) { for _, u := range urls { go http.Get(u) } }
Sample output
CRITICAL: Goroutine leak detected. http.Get is called without a timeout or way to track completion.
PREFERENCE: Use http.Client with a defined Timeout.
FIX: Use a sync.WaitGroup to wait for goroutines and pass a context.Context to handle cancellation properly.

About This Skill
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 Prompting an AI directly often results in outdated "legacy" Go patterns.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.
Use Cases
- Detect and fix goroutine leaks and race conditions in concurrent code
- Optimize memory allocations by identifying slice and map growth issues
- Modernize legacy Go code to use new 1.21+ built-ins and packages
- Enforce idiomatic error handling and proper error wrapping patterns
Known Limitations
- Cannot execute code to find runtime-only race conditions.
- Limited effectiveness on pre-Go 1.18 codebases without generics.
- No support for Cgo or Assembly auditing.
