security-hardening skillA

security-hardening is agent-read markdown (skill) from a5c-ai/babysitter: AIDefence security layer with prompt injection blocking, input validation, sandboxed execution, output sanitization, and STRIDE threat modeling..

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 a5c-ai/babysitter/security-hardening@git:20260601.da7723a
Exact content
mdr add a5c-ai/babysitter/security-hardening@sha256:dbb944f6e23df6ba

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.
