Astra Skills Collection

Skill Count: 148,134

Snapshot of deduplicated AI agent skills crawled via Astra on 2026-04-15.

Snapshot Summary

Total deduplicated skills (skills.db): 148,134
Source labels in DB: github only
Crawl time range (UTC, from DB): 2026-04-15 09:10:28 → 2026-04-15 11:59:38

What This Dataset Contains

Each saved skill directory is copied from a GitHub repository path that contains SKILL.md.

Typical structure:

{source}_{owner}_{skill_name}/
├── SKILL.md
├── _meta.json
└── [optional files, e.g. scripts/]

_meta.json stores crawl metadata such as source site, repo URL, owner, repo, skill name, and relative path.

Crawl Pipeline (Current)

Discover GitHub repositories from skill index websites (skills.sh, skillstore.io, agent-skills.md) plus configured seed repos.
Clone discovered repositories.
Recursively detect directories containing SKILL.md.
Copy skill directories into this dataset layout.
Deduplicate by MD5 hash of SKILL.md content in skills.db.

Note: website index coverage does not guarantee 100% successful retrieval of every listed skill, because repository accessibility and content availability can vary.

Intended Use

Research on tool-use and instruction-following behavior in coding agents
Skill retrieval, ranking, and composition experiments
Analysis of real-world agent skill ecosystems
