auditing-http2-and-grpc-multiplexing-trust skillA

auditing-http2-and-grpc-multiplexing-trust is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit HTTP/2 and gRPC edges for framing and multiplexing trust that breaks when a stream is translated or reused: an h2c or HTTP/2-to-HTTP/1.1 downgrade that reintroduces request smuggling, pseudo-header and header handling that lets a stream forge its path or authority, multiplexed streams on one connection whose authentication or rate limit is applied per connection rather than per stream, and a gRPC gateway that trusts metadata or a method name a caller controls. Covers HTTP/2 front ends, gRP.

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-http2-and-grpc-multiplexing-trust@git:20260829.b60f9b2
Exact content
mdr add unboundcompute/security-agent-skills/auditing-http2-and-grpc-multiplexing-trust@sha256:36005fb32e6dc68d

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.
