Go Review Command

Review Go code for idiomatic patterns and best practices: $ARGUMENTS

Your Task

1. Analyze Go code for idioms and patterns
2. Check concurrency - goroutines, channels, mutexes
3. Review error handling - proper error wrapping
4. Verify performance - allocations, bottlenecks

Review Checklist

Idiomatic Go

• Package naming (lowercase, no underscores)
• Variable naming (camelCase, short)
• Interface naming (ends with -er)
• Error naming (starts with Err)

Error Handling

• Errors are checked, not ignored
• Errors wrapped with context (fmt.Errorf("...: %w", err))
• Sentinel errors used appropriately
• Custom error types when needed

Concurrency

• Goroutines properly managed
• Channels buffered appropriately
• No data races (use -race flag)
• Context passed for cancellation
• WaitGroups used correctly

Performance

• Avoid unnecessary allocations
• Use sync.Pool for frequent allocations
• Prefer value receivers for small structs
• Buffer I/O operations

Code Organization

• Small, focused packages
• Clear dependency direction
• Internal packages for private code
• Godoc comments on exports
