What is ClaudSkills?
ClaudSkills is an open registry of Claude Code skills — small Markdown files (called SKILL.md) that give Claude Code specialized capabilities. A skill might make Claude audit your AWS infrastructure for security gaps, write sales outreach emails in your brand voice, or generate scientific literature reviews. Skills are modular, composable, and free to use.
The catalog is crawled nightly from public GitHub repositories, scored by an AI quality reviewer, and published as static pages that anyone can browse without signing up. Pro subscribers unlock one-click install via the ClaudSkills desktop app.
Skills work with Claude Code (Anthropic's CLI agent) and follow the open SKILL.md specification. The same format is also supported by Codex CLI and other coding agents.
How quality scores work
Every skill in the catalog is scored 0–100 by an AI reviewer before it is published. The score reflects:
| Dimension | What it checks | Weight |
|---|---|---|
| Completeness | YAML frontmatter has name, description, and trigger conditions | 25% |
| Clarity | Instructions are specific and unambiguous | 25% |
| Applicability | Skill addresses a real, recurring use case | 20% |
| Safety | No prompt injection risks, credential exposure, or destructive defaults | 20% |
| Originality | Not a trivial duplicate of an existing skill | 10% |
Only skills scoring 70 or above (Tier A) are published in the public catalog. Lower-scoring skills are excluded — they may exist in the source repositories but won't appear in search results or browse pages.
How the catalog is built
A nightly miner script searches public GitHub repositories for SKILL.md files using the GitHub Search API. For each discovered skill, it:
- Validates that the file follows the
SKILL.mdspecification (YAML frontmatter + instruction body) - Runs the AI quality scorer to assign a 0–100 score
- Categorizes the skill by domain (security, engineering, growth, sales, etc.)
- Generates a static HTML page at
/skills/{slug}/for search indexing - Updates the sitemap so search engines can discover new skill pages
The catalog updates twice daily. Skills added in the last 7 days appear on the What's New page. The 100 highest-scoring skills across the entire catalog are listed on the Top 100 page.
Categories
Every skill belongs to one of ten categories. Browse any category to see the top-scored skills in that domain:
- Security — vulnerability scanning, penetration testing, compliance
- Engineering — code review, architecture, testing, CI/CD
- Growth & Marketing — A/B testing, SEO, email, acquisition
- Sales — prospecting, outreach, CRM, proposals
- Content — writing, SEO content, brand voice, editorial
- Science & Research — data analysis, literature review, modeling
- Product — PRDs, roadmaps, user stories, metrics
- Dev Tools — automation, scripting, developer productivity
- Advertising — ad copy, campaign analysis, creative testing
- General — cross-domain productivity and assistance
Frequently asked questions
Skills are plain Markdown files — they are not executable code. They give Claude Code natural-language instructions. The worst a poorly written skill can do is give Claude confusing instructions. Always read the SKILL.md before installing, just as you would review any open-source dependency. The quality scorer also checks for prompt injection patterns and flags risky skills.
Publish your SKILL.md in a public GitHub repository. The nightly miner discovers new skills automatically within 24–48 hours. To fast-track your skill, use the Submit form on the homepage — it adds your repository to the next crawl cycle.
Browsing and manual install are 100% free — no account required. The Pro tier ($9/month, $79/year, or $149 lifetime) adds: one-click install via the desktop app, curated theme packs, priority support, and a weekly digest of new skills. See pricing →
Skills must score 70+ to be published. If your skill isn't appearing, check that the SKILL.md has a complete name and description in the YAML frontmatter, and that the instruction body is specific and actionable. Use the Submit form to request a re-crawl.
Yes. If you are the author of a skill and want it removed from the registry, or if you find a skill that violates safety guidelines, contact us at the email below and we will remove it from the next catalog rebuild.
