Works with your tools

How it works

01

Browse and search

Find rules, MCPs, skills, and more for your environment.

02

Check quality scores

Every asset is measured on token efficiency, security, and reliability.

03

Install with one command

Copy the install command. Works with Cursor, Windsurf, Claude, and more.

Quality is measured, not voted.

Five automated signals replace star ratings and download counts.

Token efficiency

Measures actual token consumption, not self-reported estimates.

Install success rate

Tracked across real CLI installations.

Schema cleanliness

JSON and YAML validation against published standards.

Freshness

Penalizes stale assets. Rewards active maintenance.

Security scan

VirusTotal, Semgrep, and sandboxed execution.
