skill-history
Track and visualize agent skill download history from ClawHub. An embeddable chart for READMEs — star-history, but for agent skills.
skill-history.com · built by Pineapple AI
How it works
skill-history.com tracks daily download counts for all 54,000+ skills on ClawHub. Every skill gets a chart page and an embeddable SVG:
- Chart page —
skill-history.com/{handle}/{slug} - SVG embed —
skill-history.com/chart/{handle}/{slug}.svg - Compact badge —
skill-history.com/badge/{handle}/{slug}.svg
Your {handle} is your GitHub username (ClawHub uses GitHub OAuth), and {slug} is your skill's slug on ClawHub.
Add to your README
[](https://skill-history.com/YOUR_HANDLE/YOUR_SLUG)
Or use the link generator at skill-history.com.
Architecture
- Cloudflare Workers + Hono — serves the site, chart SVGs, and scheduled sweeps
- Cloudflare D1 (SQLite) — stores skills and daily snapshots
- d3-shape — smooth monotone curves (same algorithm as star-history)
- Data source — ClawHub public API, sweeps every 2 hours
API
All skill pages return JSON when requested with Accept: application/json:
curl -H "Accept: application/json" https://skill-history.com/gavinlinasd/self-preserve
Full OpenAPI spec at skill-history.com/api/openapi.json.
For AI agents: skill-history.com/llms.txt.
