ai-skills

A curated collection of coding-convention skills for Claude Code, Codex, OpenCode, Gemini CLI, GitHub Copilot, Cursor, and 50+ more agents. Each skill teaches your AI agent the idioms, patterns, and constraints of a specific library or language so you stop explaining the same things over and over.

Installation

via pnpm / npm (recommended)

Install one skill into your Claude Code skills directory:

# pnpm
pnpm dlx skills add avbel/ai-skills -s vitest-js

# npm
npx skills add avbel/ai-skills -s vitest-js

Install multiple skills at once:

pnpm dlx skills add avbel/ai-skills -s rust-conventions -s anyhow-rust -s tokio -s axum-rust

Install all skills from this repo:

pnpm dlx skills add avbel/ai-skills --all

List available skills:

pnpm dlx skills list avbel/ai-skills

The installer auto-detects your agent and copies files to the right location. Pass --agent to override.

Manual installation (Claude Code)

Clone the repo once, then copy the skills you need:

git clone https://github.com/avbel/ai-skills.git /tmp/ai-skills

# single skill
cp -r /tmp/ai-skills/skills/vitest-js ~/.claude/skills/

# multiple skills
cp -r /tmp/ai-skills/skills/rust-conventions \
       /tmp/ai-skills/skills/anyhow-rust \
