defense-in-depth skillA
defense-in-depth is agent-read markdown (skill) from event4u-app/agent-config: Use when validation needs entry, business-logic, environment, and instrumentation guards so a bad value cannot reach the failure point — turns a local bug fix into a structural one..
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
mdr add event4u-app/agent-config/defense-in-depth@git:20260711.0f04776mdr add event4u-app/agent-config/defense-in-depth@sha256:d8bdc8e520d640cdPin 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.
