google-go-style

A Claude Code plugin that ships a single skill: google-go-style. The skill codifies the Google Go Style Guide into actionable rules that Claude consults whenever you write, review, or refactor Go code.

About

This skill encodes my interpretation of the Google Go Style Guide for use with Claude Code. The upstream guide is © Google LLC, licensed under CC-BY 3.0. This skill (SKILL.md and supporting files under plugins/google-go-style/skills/google-go-style/) is my own work, licensed Apache-2.0.

What it does

When loaded, Claude follows the rules in SKILL.md on every Go change. Topics covered:

• Naming (receivers, initialisms, repetition, test doubles, package names)
• Error handling (%v vs %w, sentinels, RPC boundaries, errors.Is / As)
• Panics, log.Fatal, and error return — when each applies
• Test discipline (no assertion libraries, t.Error vs t.Fatal, goroutines)
• API design (option struct vs variadic options, interfaces, channel direction)
• Documentation conventions
• Package layout, imports, internal/
• Variable declaration, zero values, strings, shadowing

SKILL.md is the quick-reference. Eight files under references/ carry the detailed rules; Claude loads them on demand.

Why

The upstream guide is large and not optimised for being consulted on every file edit. This skill is a digest — it puts the rules Claude needs on the hot path and leaves the long-form material as references it can fetch when a specific topic comes up.

Install

Claude Code (native plugin)

claude plugin marketplace add cicdteam/google-go-style
claude plugin install google-go-style@cicdteam

Cross-agent (Claude Code, Cursor, Codex, OpenCode, …)

npx skills add cicdteam/google-go-style

After install, Claude loads the skill automatically when triggers in its description match (writing or reviewing Go, error handling, panics, tests, API design, naming, package layout, variables and strings).

Semver

Versions follow Semantic Versioning. Breaking changes to the rule set or plugin layout bump the major; additive rule changes bump the minor; fixes bump the patch. See CHANGELOG.md for per-release notes.

Contributing

Issues are welcome — particularly if you spot a rule that contradicts the upstream guide or that's no longer current. PRs are accepted on a best-effort basis; please open an issue first for non-trivial changes so we can agree on scope.
