🤖 What are Claude Skills?

Claude Skills are reusable instructions + scripts that extend what Claude Code can do. They are auto-discovered, lazy-loaded, and composable. Think of them as plugins for your AI agent.

A skill is a folder with:

• SKILL.md — frontmatter (name, description, triggers) + instructions
• Optional helper scripts/templates
• Optional reference files

When the user's request matches a skill's triggers, Claude loads it and follows its instructions.

🚀 Why This Repo?

There are skills scattered everywhere — gists, blogs, private repos. This is the canonical, curated, tested collection.

• ✅ All skills follow the same standards (clean frontmatter, real triggers, no LLM-fluff)
• ✅ Production-ready — used in real engineering workflows
• ✅ One-line install for the whole bundle or per-skill
• ✅ Open for contributions with a strict review checklist

🧱 Skill Format

Every skill is a folder containing a SKILL.md with frontmatter:

---
name: security-audit
description: Run an OWASP-style security audit on changed files or the whole repo
triggers:
  - "audit security"
  - "find vulnerabilities"
  - "check for OWASP"
license: MIT
author: Kasim Mohammed
---

# Security Audit

When invoked, you should:
1. Identify the scope (current diff vs full repo)
2. Scan for the OWASP Top 10 patterns: ...

The frontmatter is parsed by Claude Code to register the skill. The body is the instructions Claude follows when the skill activates.

🧪 Build Your Own

./scripts/scaffold.sh my-new-skill
# Creates skills/my-new-skill/SKILL.md with a starter template

Then run the linter:

./scripts/lint.sh skills/my-new-skill

If it passes, open a PR — see CONTRIBUTING.md for the review checklist.

✅ Contribution Standards

We reject low-effort skills. To be merged, your skill must:

1. Solve a real, repeatable problem (not "make code better")
2. Have specific triggers (5+ unambiguous phrases)
3. Be lazy-loaded (no eager file reads unless triggered)
4. Include at least one example in the body
5. Pass the linter (./scripts/lint.sh)
6. Document failure modes (when NOT to use)
7. Be tested manually before submission
