auditing-third-party-script-and-sri-trust skillB

auditing-third-party-script-and-sri-trust is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit a web application for trust placed in third-party scripts it loads into its own page: an external script tag with no Subresource Integrity hash so a compromised CDN or vendor serves altered code that runs with full page privileges, a tag manager or analytics loader that injects further scripts the site never reviews, a script served over a mutable URL or wildcard source that can be swapped, and a Content-Security- Policy that is missing or permissive enough to allow arbitrary external scri.

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 unboundcompute/security-agent-skills/auditing-third-party-script-and-sri-trust@git:20260901.f8395d1
Exact content
mdr add unboundcompute/security-agent-skills/auditing-third-party-script-and-sri-trust@sha256:2038a52a15de7b2d

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.
