zero-trust skillA

zero-trust is agent-read markdown (skill) from d-padmanabhan/agent-engineering-handbook: Distinguished-engineer playbook for Zero Trust design reviews across identity, network, data, workload, and AI/agent systems. Principles-first, opinionated, threat-model-driven. Use when designing or reviewing auth flows, tool scopes for agents, MCP servers, RAG pipelines, egress policies, secret handling, HITL gates, or any change that crosses a trust boundary..

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 d-padmanabhan/agent-engineering-handbook/zero-trust@git:20260819.d23bb73
Exact content
mdr add d-padmanabhan/agent-engineering-handbook/zero-trust@sha256:b0812b9ea85da097

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.
