Review a high-level design (HLD): a design doc, RFC, architecture proposal or "how should we build X" plan. Use before implementation starts, or when asked to review, challenge or sign off a system 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
# HLD review Review the design against the real system, not against the doc's own claims. Read the design first, then read the code and config it says it touches. A finding that cites a file or a number beats one that cites a principle. ## Steps 1. **State the goal and non-goals** in two lines. If the doc doesn't make them clear, that is finding #1. 2. **Check the boundaries.** Which components own which data? Where does each request cross a process, network or trust boundary? Name every new boundary and what authenticates it. 3. **Walk the failure modes.** For each dependency: what happens when it is slow, down, or returns garbage? Look for retries without backoff or idempotency, missing timeouts, unbounded queues, and partial failure across two writes. 4. **Check data and migration.** Schema changes, backfills, rollback path, and whether old and new versions can run side by side during a rolling deploy. 5. **Check scale and cost** with numbers: expected load, the hot path, the largest table or fan-out, and what grows without bound. 6. **Check security and privacy**: who can read or write what, where secrets live, what gets logged, tenant or namespace isolation. …

How to install
mdr add thameema/memnos/hld-review@sha256:9c6f43f9e28fdeacThe line at the top of this page pins the label git:20261028.22056eb, 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.
