defense-in-depth skillA

defense-in-depth is agent-read markdown (skill) from ed3dai/ed3d-plugins: Use when invalid data causes failures deep in execution - validates at every layer data passes through to make bugs structurally impossible rather than temporarily fixed.

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 ed3dai/ed3d-plugins/defense-in-depth@git:20260204.611bfd1
Exact content
mdr add ed3dai/ed3d-plugins/defense-in-depth@sha256:9e807033e7dd7d8c

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.
