Go Development Skill

Instructions

When working with Go code, follow these rules:

1. Logging: Use the log/slog package in the standard library.
   • Add appropriate log messages with proper log levels.
2. Interfaces: Define interfaces where they are used, not where they are implemented.
   • Avoid introducing unused interfaces.
3. Testing:
   • Use table-driven tests.
   • Clarify which case is failing in the test log.
4. Linting:
   • Run make lint to check for issues.
   • Run make fix to auto-fix issues.
   • If running manually: golangci-lint run ./...
5. Flags: Only the main function can access command-line flags.

Tools

• Lint: make lint
• Test: make test
