Audit an existing or proposed architecture and return a scored verdict across nine axes, from requirements and capacity evidence to observability and rollout, then convert gaps into a prioritized roadmap. Use when reviewing a design doc, auditing a running system, or gating a design.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# System Design Review

## **Priority: P1 (HIGH)**

Score claims against evidence appropriate to the declared review scope. A proposed design may support a design-readiness verdict through stated mechanisms and planned validation; it cannot claim operational readiness from plans alone. An implementation review requires implementation evidence; an operations claim requires production runtime/deployment evidence.

## Nine Axes (score each applicable axis 0-10)

| Axis | Scores 10 when | Scores 0 when |
| --- | --- | --- |
| Requirements | Functional, NFR, and out-of-scope written with owners | Only a feature description exists |
| Capacity evidence | Peak QPS, storage, and bandwidth computed and current | Numbers absent or older than the last traffic change |
| Redundancy | Failure domains, recovery mechanisms and ownership fit the stated objective; proposals include validation criteria, operations claims require measured drills when recovery is in scope | Critical SPOF or no viable recovery for the stated objective |

How to install

The exact contents, by fingerprint
mdr add hoangnguyen0403/agent-skills-standard/system-design-review@sha256:2ea78f997d334582

The line at the top of this page pins the label git:20261021.8da3953, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
