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.

Install with skills CLI (universal, works with any Agent Skills-compatible tool):

npx skills add https://github.com/samber/cc-skills-golang --all
# or a single skill:
npx skills add https://github.com/samber/cc-skills-golang --skill golang-performance

/plugin marketplace add samber/cc
/plugin install cc-skills-golang@samber

git clone https://github.com/samber/cc-skills-golang.git ~/.openclaw/skills/cc-skills-golang
# or in workspace:
git clone https://github.com/samber/cc-skills-golang.git ~/.openclaw/workspace/skills/cc-skills-golang

gemini extensions install https://github.com/samber/cc-skills-golang

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

/plugin install https://github.com/samber/cc-skills-golang
# or
git clone https://github.com/samber/cc-skills-golang.git ~/.copilot/skills/cc-skills-golang

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

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

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

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.

General purpose:

Tools:

See EVALUATIONS.md for the full per-skill breakdown.

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 — small wording adjustments can significantly improve trigger accuracy. Some SKILL.md files might have a When to use section which is another level of exclusion. Finally, SKILL.md files are an entrypoint for lazy loading references with deep knowledge located in references/.

Claude reports very little overlap between skills in this repo, thanks to cross-reference. I suggest enabling most of the skills and leveraging lazy loading. The recommended ⭐️ 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 the Bearer (SAST) checklist. 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 ⚙️ in the table above support this mechanism.

• 100 tokens per skill description - what? when to use this skill?
• 1.000–2.500 tokens per SKILL.md — keep the main file focused on essentials
• Use secondary markdown files for depth — 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
• 2–4 skills loaded simultaneously in a typical session — design skills to coexist
• Stay below ~10k tokens of total loaded SKILL.md anytime to avoid degrading response quality
