The expanding universe of Claude Skills, catalogued

What it does

This repository is a curated directory of skills for Claude Code and Claude.ai. It collects official Anthropic tools alongside community-built integrations, prompt packs, and API connectors, then sorts them into categories like document processing, development workflows, data analysis, and scientific computing.

The interesting bit

The scope is almost comically broad. You will find a skill for generating Reveal.js slides next to one for debugging with breakpoints, another for managing Azure DevOps pipelines, and yet another for simulating multi-agent social media arguments. It is a direct look at what developers are currently trying to make autonomous.

Key highlights

• Mix of first-party Anthropic skills (docx, pdf, web-artifacts-builder) and third-party submissions.
• Highly specific verticals are represented: Move language quality checks, Bitcoin Lightning architecture reviews, materials simulation, and Charles Proxy traffic extraction.
• Includes meta-tooling like agnix, a linter for AI agent configurations, and claude-starter, a template bundling 40 auto-activating skills.
• Several entries expose live APIs or database connections rather than simple prompt templates.

Caveats

• The README is a pure directory: one-line descriptions and links, with no usage guidance, compatibility notes, or quality curation beyond broad categorization.

Verdict

Worth bookmarking if you are trying to automate a specific workflow with Claude and want to see what already exists. Skip it if you are looking for a package manager, versioned registry, or vetted quality gate — this is a hand-curated link dump, not an app store.
