custom-sanitizer-audit skillB

custom-sanitizer-audit is agent-read markdown (skill) from dreadnode/capabilities: Audit custom sanitization functions for bypass vulnerabilities using the Five-Point Checklist and ordering analysis. Use when encountering homegrown sanitize/filter/clean/escape functions, reviewing input validation, or testing custom security wrappers..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
