# Agent 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](https://github.com/samber/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.
## 🚀 How to use
**Install with [skills](https://skills.sh/) CLI** (universal, works with any [Agent Skills](https://agentskills.io)-compatible tool):
```bash
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
```
Claude Code
```bash
/plugin marketplace add samber/cc
/plugin install cc-skills-golang@samber
```
Openclaw
Copy skills into the cross-client discovery directory:
```bash
git clone https://github.com/samber/cc-skills-golang.git ~/.openclaw/skills/cc-skills-golang

OpenCode
Copy skills into the cross-client discovery directory:
```bash
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:
```bash
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
Clone and symlink into the cross-client discovery path:

## 🧩 Skills
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.

## 🎯 Tuning Skill Triggers
If a skill triggers too often or not often enough, please [open an issue](https://github.com/samber/cc-skills-golang/issues) 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/`.
## 🔄 Overlap
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.
## ✍️ Contribute
- **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
For more guidelines, please check `CLAUDE.md`.
