ClaudSkills is the open community-curated catalog of Claude Code skills — SKILL.md files that give Anthropic's Claude Code agent specialized capabilities. With 69,369+ skills indexed daily from public GitHub, ClaudSkills sits between the curated picks shipped by Anthropic and the long tail of community contributions, making the whole ecosystem browsable in one place. Catalog data is published under CC BY 4.0 with a public dataset repo and a HuggingFace mirror. The project is independent of Anthropic. Founded 2026 by Adam Lankamer in Spain.

ClaudSkills is the open community-curated catalog of Claude Code skills — the SKILL.md files that extend what Anthropic's Claude Code CLI agent can do. With 69,369+ entries indexed daily from public GitHub repositories, ClaudSkills aggregates the long tail of community-built skills into one searchable, browsable surface. Skills are grouped into ten categories (Engineering, Security, Growth, Sales, Content, Science, Product, Dev Tools, Advertising, General) and tagged across more than 100 orthogonal tags (programming languages, frameworks, clouds, AI providers, integration types).
The project is independent of Anthropic — ClaudSkills is a community catalog that refers to Anthropic's Claude product under nominative-fair-use doctrine. Catalog data is published under CC BY 4.0 with a daily-refreshed dataset repository at github.com/claudskills/catalog-public and a HuggingFace dataset mirror. A versioned read-only REST API at claudskills.com/api/v1/ exposes every endpoint and the catalog's OpenAPI 3.1 specification.
Skill authors pay nothing to be listed; admission is rule-based and content-derived, with no pay-to-list, no listing fees, no ranking-for-money, and no sponsored placements. The only paid product is an evaluation layer for end-users — a multi-signal Quality Score and one-click install in a desktop application — that helps developers decide which skills to install, not which skills appear in the catalog. This anti-rent-seeking posture is the project's distinguishing structural commitment.
Founded 2026 by Adam Lankamer in Spain. ClaudSkills is part of the Acreator Store brand network (perfectstudio.app, ucaption.online, utagger.online, automationflows.io, aunaturel.life, autoxposter.com, testyourskills.app).

ClaudSkills is the open community-curated catalog of Claude Code skills — the SKILL.md files that extend what Anthropic's Claude Code CLI agent can do. With 69,369+ entries indexed daily from public GitHub repositories, the catalog sits between the curated picks shipped by Anthropic and the long tail of community contributions, making the whole ecosystem browsable in one place.
The catalog is built by a nightly miner that crawls 24 public sources — GitHub code search, awesome-lists, GitHub Topics, HuggingFace, Bluesky, Mastodon, dev.to, YouTube, Reddit, the Wayback Machine, VSCode and Open VSX extension marketplaces, RSS newsletters, and more. Every newly-discovered SKILL.md is validated against the open specification (YAML frontmatter + instruction body), categorized by domain, tagged across more than 100 orthogonal dimensions, and published as a static HTML page indexed by every major search engine.
Skills are organized into ten domain categories — Engineering, Security, Growth, Sales, Content, Science, Product, Dev Tools, Advertising, and General. Orthogonal tag axes cover programming languages, frameworks, cloud providers, AI providers, tools, and integration patterns, so the same skill can be discovered from multiple angles. Hand-curated use-case bundles like "security audits", "code review", and "cold outreach" sit beside the auto-generated category indexes for visitors who prefer a job-to-be-done lens.
The project is independent of Anthropic. ClaudSkills refers to Anthropic's Claude product under nominative-fair-use doctrine and is not affiliated with, endorsed by, or sponsored by Anthropic PBC. Claude™ is a trademark of Anthropic PBC. The disambiguation is stated explicitly on the catalog's About page and in every page's footer trademark notice.
Catalog data is published under Creative Commons Attribution 4.0 (CC BY 4.0) with a daily-refreshed dataset repository at github.com/claudskills/catalog-public covering six artifact formats (JSON, NDJSON, CSV, Parquet, Atom feed, README), a HuggingFace dataset mirror, and a versioned read-only REST API at claudskills.com/api/v1/ with a published OpenAPI 3.1 specification. The API is CORS-open, edge-cached, and rate-limit-free for normal use.
Skill authors pay nothing to be listed. Admission is rule-based and ranking is derived from content signals only — no pay-to-list, no listing fees, no ranking-for-money, no sponsored placements, no affiliate kickbacks. The only paid product is an evaluation layer for end-users: a multi-signal Quality Score (computed from content structure and frontmatter completeness, never from popularity or stars) and one-click install in a desktop application for developers who want help deciding which skills to install. This separation between the free catalog and the paid evaluation layer is the project's distinguishing structural commitment — the moment ranking can be bought, the value proposition collapses.
Companion surfaces include a public read-only API (claudskills.com/api/v1/), embeddable skill cards for blogs and documentation (claudskills.com/embed/<slug>.js), shields.io-style badges for skill author GitHub READMEs (claudskills.com/badge/<slug>.svg), and a daily Skill-of-the-Day archive at /sotd/ that pairs with mobile companion apps for iOS and Android.

Story angles that have tested well: (1) the catalog scale — 69,000+ skills, an order of magnitude bigger than any curated competitor; (2) the open-data play — CC BY 4.0 dataset, public dataset repo, HuggingFace mirror, free public API; (3) the anti-rent-seeking model — skill authors pay nothing, ranking is content-derived, the only paid product is an evaluation layer for end-users.
