url-validation-security skillA

url-validation-security is agent-read markdown (skill) from patrickserrano/lacquer: Use when validating a user-provided or externally-sourced URL before it reaches `AVPlayer`, `URLSession`, or a `WKWebView` — building a positive- allowlist URL validator, or reviewing existing networking/media code for missing URL validation..

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.

How to install

Latest version
mdr add patrickserrano/lacquer/url-validation-security@git:20260725.3f0d943
Exact content
mdr add patrickserrano/lacquer/url-validation-security@sha256:f5025547c35c2ec4

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
