auditing-mobile-deeplink-trust skillA

auditing-mobile-deeplink-trust is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit how a mobile app handles a deep link, app link, or custom-scheme URL, so an attacker-supplied URL cannot drive a sensitive action or reach a trusted WebView context. Covers a custom scheme any app can register and hijack, an app link whose domain association is unverified so the link is not exclusively the app's, a deep-link parameter that flows unvalidated into a sensitive action, an attacker-controlled URL loaded into a WebView, and a JavaScript bridge exposed to a WebView that can load .

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-mobile-deeplink-trust@git:20260823.e797ed0
Exact content
mdr add unboundcompute/security-agent-skills/auditing-mobile-deeplink-trust@sha256:a64c8b8abda581f0

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.
