Designs system structure and makes architectural decisions defensible — boundaries, coupling, trade-offs, and recording why. Use this to design a new system or major component, choose between architectural options, review an existing design, decide where a boundary belongs, or document an architectural decision so it survives the people who made it.
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
# Solution architecture Architecture is the set of decisions that are expensive to reverse. Everything cheap to change later is design, and does not need this level of ceremony. ## Start from what constrains, not from what appeals Architecture is driven by quality attributes, not by features. Establish the ones that actually bind before drawing anything: expected load and its shape, latency the user notices, availability the business will fund, data residency and retention obligations, the rate of change the team needs to sustain, and the size and skills of the team who will operate it. Vague attributes produce vague architecture. "Scalable" is not a requirement; "20,000 concurrent sessions with p99 under 300ms" is a constraint that eliminates options. ## Boundaries are the whole game Draw boundaries where change is independent and where data has a single owner. A boundary in the right place absorbs change; a boundary in the wrong place turns every feature into a negotiation across three teams. The reliable test: if a routine change requires coordinated deployment across two components, the boundary is wrong regardless of how clean the diagram looks. …

How to install
mdr add cbrock84/headcount/solution-architecture@sha256:8566ce50cb991f87The line at the top of this page pins the label git:20260916.e72e404, 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.
