Claude Code Skills for production-ready Golang projects

AI agent skills are reusable instruction sets that extend your coding assistant with domain-specific expertise, loaded on demand so they don't bloat your context. This repository covers Go-specific skills only (language, testing, security, observability, etc.); for dev workflow skills (git conventions, CI/CD, PR reviews) you'll want to add a separate skills plugin.

For generic skills, please visit cc-skills.

Important

Bootstrapped with Claude Code by distilling my Go project commits. Edited, tested, reviewed and reworked by a human.

No AI slop here. AI-made skills are useless.

git clone https://github.com/samber/cc-skills-golang.git ~/.agents/skills/cc-skills-golang

OpenCode auto-discovers skills from .agents/skills/, .opencode/skills/, and .claude/skills/.

Codex (OpenAI)

Clone into the cross-client discovery path:

git clone https://github.com/samber/cc-skills-golang.git ~/.agents/skills/cc-skills-golang

Codex auto-discovers skills from ~/.agents/skills/ and .agents/skills/. Update with cd ~/.agents/skills/cc-skills-golang && git pull.

Antigravity

These skills are designed as atomic, cross-referencing units. A skill may reference conventions defined in another (e.g. error-handling rules that affect logging live in golang-error-handling, not golang-observability). Installing only a subset will give you a partial and potentially inconsistent view of the guidelines. For best results, install all general-purpose skills together.

๐ŸŽฏ Tuning Skill Triggers

If a skill triggers too often or not often enough, please open an issue suggesting a description change. The description field in SKILL.md frontmatter is the primary triggering mechanism โ€” small wording adjustments can significantly improve trigger accuracy. Some SKILL.md might have When to use section which is another level of exclusion. Finally, SKILL.md are a entrypoint for lazy loading references with deep knowledge located in references/.

๐Ÿ”„ Overlap

Claude reports very little overlap between skills in this repo, thanks to cross-reference. I suggest enabling most of the skills and leverage lazy loading. The recommended โญ๏ธ skills load ~1,100 tokens of descriptions at startup; full skill content is only pulled in when relevant. Note:

  • I estimate that 50% of golang-naming and golang-code-style overlap with linters (golangci-lint).
  • A large part of the security rules in golang-security have been distilled from Bearer (SAST) check list. The skill is still useful for methodology.
  • If your team has its own conventions, create a company skill and declare the override explicitly near the top of its body: This skill supersedes samber/cc-skills-golang@golang-naming skill for [company] projects. Skills marked โš™๏ธ in the table above support this mechanism.

โœ๏ธ Contribute

  • 100 tokens per skill description - what ? when use this skill ?
  • 1.000โ€“2.500 tokens per SKILL.md โ€” keep the main file focused on essentials
  • Use secondary markdown files for depth โ€” reference them from SKILL.md with relative links (e.g., [Logging](./logging.md)). Claude reads these on demand when the topic is relevant, so they don't count against the context budget until needed
  • Up to 10.000 tokens for full skill and secondary files
  • 2โ€“4 skills loaded simultaneously in a typical session โ€” design skills to coexist
  • Stay below ~10k tokens of total loaded SKILL.md anytime to avoid degrading response quality

For more guidelines, please check CLAUDE.md.
