I Catalogued 1,000+ Open-Source Claude Agent Skills. Here’s What the Ecosystem Actually Looks Like.

Description and use

A centralized index of over 1,000 Claude Agent skills was created to streamline discovery, classification, and download, emphasizing concise descriptions and bundled scripts.

Problem

Finding and using Claude agent skills was fragmented, time‑consuming, and unreliable, with many skills lacking descriptions, being broken, or residing in inconsistent folder structures.

Outcome

The index reduced skill discovery time, improved reliability, and provided a clear structure for developers to build or extend Claude agent skills.

Workflow

• Collect skill repositories from Anthropic and community collections
• Clone each repo and extract SKILL.md and script files
• Classify skills into five functional buckets
• Generate concise descriptions and trigger conditions
• Publish a single-page index with download links and Arabic documentation

Evidence

I got tired of it, so I indexed the whole thing. Over a thousand skills, pulled from Anthropic's public repositories and the largest community collections, then classified, described, and made downloadable from one page.

Source

The description is loaded based on its description. That field is not documentation. It is a routing decision.
