Same prompt. Three context files. Three very different dashboards.
A design.md file is only as good as its detail. We gave Claude the identical prompt three times — the only variable was the design context sitting in the project root. Here is what came back, unedited.
Test run: June 2026Methodology
One prompt, three runs, fresh context each time. Run 1 got the 450-line Supabase-inspired design.md from our library. Run 2 got a deliberately minimal 35-line version — the kind of quick writeup most projects have. Run 3 got no design file at all. Outputs were not edited afterward.
Build a single-file static HTML analytics dashboard for a Postgres database platform. It must include: a left sidebar with navigation, a top bar with the project name and a primary action button ("New query"), four stat cards (Database size, Active connections, Queries / sec, Cache hit rate), a table of the five most recent queries (query, duration, rows, status), and a usage chart placeholder area. Use only inline CSS in a <style> tag — no external libraries, no JavaScript. Follow the design context provided with this prompt; if none is provided, use your own judgment.

Token counts are machine-readable tokens computed from the actual context files used in the test. The minimal file mentions colors and components in prose, but defines zero structured tokens — which is exactly why the AI had to guess. The frozen files and the screenshot script live in the project so the run can be reproduced.
Detail is the difference.
Every file in our library is written at the depth of the first column — exact tokens, full component specs, usage rules an AI can actually follow.
