Claude Skills Registry

Core repo: logic + index + site.
Main repo (merged artifact): https://github.com/majiayu000/claude-skill-registry
Data repo (skills archive): https://github.com/majiayu000/claude-skill-registry-data
Authority: core workflows are canonical; main is a publish mirror.

The most comprehensive Claude Code skills registry — updated daily with the latest skills

What is this?

The largest searchable index of Claude Code skills, aggregated from GitHub and community sources.

Three ways to use:

1. Web Search - Fast browser-based search
2. sk CLI - Terminal package manager
3. API - Direct JSON access

Repo layout note: core owns workflows/pipeline logic, data stores skills/**, and main is generated from core + data. See SCHEME2_SPLIT.md.

Generated Mirror Notice

This repository is the merged publish artifact for browsing and compatibility consumers. Source changes for discovery, download, security scanning, index generation, search, Pages, or publish orchestration belong in claude-skill-registry-core. Archived skill body and archive metadata issues belong in claude-skill-registry-data.

• Do not submit normal source PRs here unless the change is explicitly main-owned, such as publish workflow routing or mirror-only repository metadata.
• Release status: this mirror does not cut independent GitHub Releases for daily generated data. Use provenance/merge-source.json, registry_summary.json, and the generated timestamps to identify the exact core_sha and data_sha behind an artifact.
• Use issues here only for mirror artifact problems, such as mismatched generated files, broken compatibility paths, or incorrect provenance after publish.

Highlights

• Massive Skill Index - Deduplicated, high-quality registry (see badge for live count)
• Rich Categories - Development, Testing, DevOps, Design, and more
• Daily Updates - Automated crawling/validation by core scheduled workflows
• Quality Indexed - Metadata, descriptions, and star counts
• Lightweight Search - Gzip-compressed index for fast client-side search

Operational Ownership

• Core: source of truth for workflows, crawling, scanning, and index/site generation
• Data: canonical archived skill tree (skills/**)
• Main: publish artifact for merged browsing/compatibility consumers
• Publish contract: core dispatches main publish with pinned core_sha + data_sha
• Non-goal for main: main does not initiate canonical syncs, archive updates, or index generation

Quick Start

Option 1: Web Search

Visit https://majiayu000.github.io/claude-skill-registry-core/

For clone/update tips on large repositories, see docs/FAST_CLONE.md.

Option 2: CLI (sk)

# Install sk
go install github.com/majiayu000/caude-skill-manager@latest

# Search skills
sk search testing
sk search pdf
sk search --popular

# Install a skill
sk install anthropics/skills/skills/docx

Option 3: Direct API

The public JSON surface is versioned in docs/artifact-api-contract.md. Use that contract when integrating with pointer files, manifests, shards, gzip variants, and deprecation markers.
