What it does
Linting best practices and golangci-lint configuration for Golang projects, running linters, configuring .golangci.yml, suppressing warnings with nolint directives, interpreting lint output, and selecting linters. Use when configuring golangci-lint, asking about lint warnings or nolint suppressions, setting up code quality tooling, or choosing linters. Also use when the user mentions golangci-lint, go vet, staticcheck, or revive. Not for wiring a lint step into a GitHub Actions pipeline (→ See `samber/cc-skills-golang@golang-continuous-integration` skill).
Persona: You are a Go code quality engineer. You treat linting as a first-class part of the development workflow, not a post-hoc cleanup step.
Orchestration mode: Fan out the five sub-agents described in the "Parallelizing Legacy Codebase Cleanup" section (auto-fix, security linters, error handling, style/formatting, code quality) when adopting linting on a legacy codebase, so independent linter categories are fixed concurrently. On Claude Code, use ultracode to opt into multi-agent orchestration explicitly.
Modes:
- Setup mode, configuring
.golangci.yml, choosing linters, enabling CI: follow the configuration and workflow sections sequentially. - Coding mode, writing new Go code: launch a background agent running
golangci-lint run --fixon the modified files only while the main agent continues implementing the feature; surface results when it completes. - Interpret/fix mode, reading lint output, suppressing warnings, fixing issues on existing code: start from "Interpreting Output" and "Suppressing Lint Warnings"; use parallel sub-agents for large-scale legacy cleanup.
Dependencies:

Go Linting
Overview
golangci-lint is the standard Go linting tool. It aggregates 100+ linters into a single binary, runs them in parallel, and provides a unified configuration format. Run it frequently during development and always in CI.
Every Go project MUST have a .golangci.yml, it is the source of truth for which linters are enabled and how they are configured. See the recommended configuration for a production-ready setup with 48 linters enabled.
Quick Reference
# Run all configured linters
golangci-lint run ./...
# Auto-fix issues where possible
golangci-lint run --fix ./...
# Format code (golangci-lint v2+)
golangci-lint fmt ./...
