About
Security Cards are open-sourced, library-specific security guidance covering 80+ widely used libraries across 13 languages, designed to be consumed by AI coding agents like Claude Code. In evaluation on the BaxBench benchmark, applying the cards via an installable skill reduced insecure code generation by up to 72.3% with Claude Opus 4.7.
What it does
According to its own site, Security Cards is a set of security guidance entries for more than 80 programming libraries, packaged as an installable skill so an AI coding agent can pull in relevant rules while implementing or reviewing a feature, instead of relying only on its own training knowledge.
