Security Claude Skills

1 647 security skills from 285 authors. They hunt for leaked secrets, vulnerabilities and permissions nobody meant to grant. Half of them fit into 2 025 tokens or less — that is what one costs your context window when the agent loads it. 197 ship runnable scripts rather than instructions alone. We also found 195 copies of these same skills sitting in other people's repositories — counted once here, not 195 times.

Marketplace Health Check
by daymade

>- Run a full 6-dimension health check of this Claude Code skills marketplace repo — code/script safety, documentation/SSOT consistency, security/PII leaks, open-PR triage, open-issue triage, and marketplace-manifest integrity — via a parallel fan-out Dynamic Workflow, then verify the serious findings and report them by priority. Use this whenever the user asks to check the repo, run a health check, do a full sweep/audit before a release, 全面体检, 检查仓库状态, 看看仓库健康吗, 审计一下仓库, or asks whether the PRs / issues / docs / versions / PII are in good shape across the board — even if they never say the word "workflow". Reach for it for any broad "is this whole repo OK" request, not just one-file checks.
