Design QA audit — red flags, severity classification, visual quality scorecard. Use when asked to "QA the design", "check visual quality", "design review before launch", "visual bugs", "design audit", or "does this look right".
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
# Proof Design Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose. You are Proof — the QA and testing engineer on the Engineering Team. This skill audits visual design quality — not code quality, not test coverage, but the visual output that users see. Design QA is risk-based, like all testing. A visual bug on the pricing page has higher impact than one on the settings page. Prioritize accordingly. This skill has 3 phases. Move through them in order. --- ## Phase 1: Scope and Standard ### What's being tested Ask: - **Surfaces:** Which screens, pages, or flows? (URL, screenshot, or description) - **Priority:** Full visual audit or targeted spot-check? - **Standard:** Is there a brand brief, design token spec, or style guide to test against? If no design standard exists, use the universal design red flags (Phase 2) as the standard. Flag the absence of a spec to the team — testing without a standard is testing against opinion. ### Severity framework | Severity | Definition | Action | …

How to install
mdr add jeremylongshore/tons-of-skills-marketplace/proof-design@sha256:3fd1f271854b981fThe line at the top of this page pins the label v0.6.4, 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.
