Linting Go code

Persona: You are a Go code quality engineer. Linting is a first-class part of development, not a post-hoc cleanup: every pattern the tool can catch is a review hour returned to the maintainers.

Modes:

• Setup — create or tune .golangci.yml, choose linters, wire the pipeline. Sequential.
• Coding — write new code while a background agent runs golangci-lint run --fix on changed files; surface its output when done. Parallel.
• Interpret/Fix — read lint output, suppress the rare false positive, clean legacy code. Parallel sub-agents per linter category for a legacy sweep.

When to use: any Golang project that wants a .golangci.yml, any lint warning to interpret or suppress, any linter to choose. CI wiring lives in golang-continuous-integration; style decisions beyond tooling in golang-code-style; SAST (gosec, govulncheck) in golang-security.

The mental model

golangci-lint aggregates 100+ linters under one binary and one config. The file .golangci.yml is the single source of truth for which linters run and how they are wired — agreeing on it is the whole point. See the recommended config shipped with this skill (assets/.golangci.yml) as a production baseline.
