⚡ Quick start

Option A — install as a Claude Code plugin (recommended). One command, auto-updating:

/plugin marketplace add frankxai/claude-skills-library
/plugin install claude-skills-library@claude-skills-library

Skills are now discovered automatically and activate when relevant.

Option B — clone and copy the skills you want:

git clone https://github.com/frankxai/claude-skills-library.git ~/claude-skills-library
mkdir -p ~/.claude/skills

# one skill…
cp -r ~/claude-skills-library/free-skills/mcp-architecture ~/.claude/skills/
# …or all of them
cp -r ~/claude-skills-library/free-skills/* ~/.claude/skills/

Some skills are namespaced (e.g. free-skills/anthropic/pdf). Copy the folder that directly contains the SKILL.md you want. Restart Claude Code and the skills are discovered.

Then just work. Skills trigger on their own, or invoke one explicitly:

"Use the greek-philosopher skill to examine my career decision."
"Design an MCP server with the mcp-architecture skill."
"Review this PR with the github-code-review skill."
"Write a Suno prompt for a cinematic trailer track."

🚀 What is this?

A curated, open-source library of Agent Skills — the portable, model-invoked capability format from Anthropic. Drop a skill into your agent and it gains expert knowledge in a domain: it loads automatically when relevant and stays out of the way when it isn't.

Every skill here:

• ✅ Is a self-contained folder with a SKILL.md and optional references/, scripts/, assets/.
• ✅ Has spec-compliant frontmatter (name + description) — enforced by scripts/validate_skills.py.
• ✅ Is progressive-disclosure friendly: a tight description for routing, deep guidance loaded only on use.
• ✅ Carries a trigger-rich description so the right skill activates from a library of 100+.

107 skills across AI agents, MCP & SDKs, frontend, Oracle/cloud, content & creative production, engineering workflow, and personal performance. All free. MIT-licensed.
