golang-lint — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited golang-lint (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
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.
Modes:
.golangci.yml, choosing linters, enabling CI: follow the configuration and workflow sections sequentially.golangci-lint run --fix on the modified files only while the main agent continues implementing the feature; surface results when it completes.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.
# Run all configured linters
golangci-lint run ./...
# Auto-fix issues where possible
golangci-lint run --fix ./...
# Format code (golangci-lint v2+)
golangci-lint fmt ./...
# Run a single linter only
golangci-lint run --enable-only govet ./...
# List all available linters
golangci-lint linters
# Verbose output with timing info
golangci-lint run --verbose ./...The recommended .golangci.yml provides a production-ready setup with 33 linters. For configuration details, linter categories, and per-linter descriptions, see the [linter reference](./references/linter-reference.md) — which linters check for what (correctness, style, complexity, performance, security), descriptions of all 33+ linters, and when each one is useful.

Each issue follows this format:
path/to/file.go:42:10: message describing the issue (linter-name)The linter name in parentheses tells you which linter flagged it. Use this to:
//nolint:linter-name // reason if it's a false positivegolangci-lint run --verbose for additional context and timing| Problem | Solution |
|---|---|
| "deadline exceeded" | Set or increase run.timeout in .golangci.yml; golangci-lint v2 defaults to no timeout (0) |
| Too many issues on legacy code | Set issues.new-from-rev: HEAD~1 to lint only new code |
| Linter not found | Check golangci-lint linters — linter may need a newer version |
| Conflicts between linters | Disable the less useful one with a comment explaining why |
| v1 config errors after upgrade | Run golangci-lint migrate to convert config format |
| Slow on large repos | Reduce run.concurrency or exclude paths with linters.exclusions.paths / formatters.exclusions.paths |
