# Skills Directory

> The security-first directory of skills for Claude, Claude Code, and coding agents. Every listed skill is automatically security-scanned and graded A–F before it appears, so people and agents can filter to safe, vetted skills. Free, no login required.

- 650,507 indexed skills, 650,507 security-scanned
- Grade distribution: A: 626,413 · B: 15,441 · C: 5,240 · D: 2,110 · F: 1,303
- What makes this directory different: every skill gets an automated multi-rule security scan (credential reads, network exfiltration patterns, unpinned remote code, prompt-injection vectors) and a public grade with a per-skill report. Sponsors can never buy grades or hide findings.
