auditing-multi-tenant-isolation skillA

auditing-multi-tenant-isolation is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit whether every data operation is scoped to the caller's tenant, so a request in one tenant cannot read or write another's data. Covers a query or object lookup with the object identifier but no tenant predicate, a tenant taken from client-controlled input at the operation rather than the authenticated session, scoping applied on the list path but dropped on the detail, update, delete, or export path, a cache or storage key with no tenant segment, and a background job, report, or privileged .

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-multi-tenant-isolation@git:20260821.57dfaf1
Exact content
mdr add unboundcompute/security-agent-skills/auditing-multi-tenant-isolation@sha256:2b9809990b030644

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.
