auditing-grpc-service-authorization skillA

auditing-grpc-service-authorization is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit a gRPC service for a method a caller can reach without the authorization the service assumes an interceptor enforces, after the interceptor coverage and the channel credentials are resolved. Covers authorization installed on the unary interceptor while the streaming chain omits it, a per-method authorization gap reachable at the wrong privilege, server reflection enabled in production exposing the full API, a plaintext channel with metadata trusted unverified, an absent message-size or rec.

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-grpc-service-authorization@git:20260825.70f8609
Exact content
mdr add unboundcompute/security-agent-skills/auditing-grpc-service-authorization@sha256:84cf92d10446dcaf

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.
