system-design skillA

system-design is agent-read markdown (skill) from yarlson/yarstack: Design the smallest system or feature architecture that satisfies stated current requirements, for a greenfield product or a new capability in an existing codebase. Use when the user wants a proposed design with components, non-goals, and growth triggers; not for investigating existing behavior, settling one open decision, or planning phases..

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 yarlson/yarstack/system-design@git:20260903.c5d000e
Exact content
mdr add yarlson/yarstack/system-design@sha256:6b453604e90221b5

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.
