Generate golangci-lint Configuration

Instantly create a professional .golangci.yml configuration for Go projects with comprehensive linting coverage. This skill replaces the multi-step manual setup with a single invocation.

Why This Skill Exists

Problem: Setting up golangci-lint requires manually creating YAML configuration, understanding 90+ linter options, and balancing strict quality checks with pragmatic development - a 15-30 minute process prone to over-configuration.

Solution: One-command generation that:

• Creates battle-tested .golangci.yml (224 lines)
• Enables all linters by default with sensible exclusions
• Balances code quality with development velocity
• Works out-of-the-box for most Go projects
• Includes inline documentation for customization

Content Generation Rules

CRITICAL: When generating any content (configuration files, commit messages, or any other output):

• NEVER add Claude Code attribution or co-authorship
• NEVER include phrases like "Generated by Claude", "Created with Claude Code", or similar
• NEVER add "Co-Authored-By: Claude" in commit messages or documentation
• All generated content should appear as if written by a human developer
• Focus on technical accuracy and providing working templates

Process (6 Phases)

Phase 1: Prerequisites Validation

Critical checks before proceeding:

1. Validate Git repository:

   git rev-parse --git-dir
   

   • If fails: Exit with error "Not a git repository. Run 'git init' first."

2. Validate Go project:

   test -f go.mod
   

   • If fails: Exit with error "go.mod not found. This skill is for Go projects only."

3. Check existing configuration:

   test -f .golangci.yml || test -f .golangci.yaml
   

   • If either exists: Store existingConfig = true and existingFile = <filename>
   • If not exists: Store existingConfig = false

4. Check for golangci-lint binary (non-blocking):

   command -v golangci-lint
   

   • If not found: Store linterNotInstalled = true (will show warning later)
   • If found: Check version with golangci-lint --version and store for report
