auditing-ios-app-group-and-pasteboard-exposure skillA

auditing-ios-app-group-and-pasteboard-exposure is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit sensitive data leaving an iOS app's protection through shared containers and system-wide channels, where a secret or private value is written to a shared app-group container, a shared keychain access group, the general pasteboard, or app state that lands in snapshots and extensions, so another app, an app extension, or any process reading the pasteboard can recover it, because the shared surface is broader than the data's sensitivity requires. Use when reviewing what an iOS app shares with.

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-ios-app-group-and-pasteboard-exposure@git:20260908.e3ae18a
Exact content
mdr add unboundcompute/security-agent-skills/auditing-ios-app-group-and-pasteboard-exposure@sha256:d6f060999977c8b9

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.
