Decision brief
Produce a single-file HTML "design review report" that scores any artifact across 5 dimensions and proposes actionable fixes. Inspired by the huashu-design expert-critique flow.

Installation
The source command is displayed only when detected. A safe inspection prompt is always available so your agent can explain every action before execution.

Workflow
1. Project file — user said "review the index.html I just made": open it from the project folder. 2. Pasted HTML — user pasted code in the chat: read it from the message. 3. Generated by you in this turn — you just emitted an artifact above and want to self-critique: re-read you…

Skim the entire , then read 6–8 representative content blocks. Do not score from frontmatter alone. The score depends on executed design, not declared intent.
For each of the 5 dimensions, write the score and a 30–80 word evidence paragraph that names specific elements. Use line numbers, class names, page numbers.
Aggregate the 5 evidence paragraphs into:

Pinned source
Produce a single-file HTML "design review report" that scores any artifact across 5 dimensions and proposes actionable fixes. Inspired by the huashu-design expert-critique flow.
A single self-contained <artifact type="text/html"> review report
including:
Each dimension is independent — a deck can be 9/10 on Innovation but 4/10 on Hierarchy and the report should say so plainly. Don't average away interesting failures.
Does the artifact pick a clear direction and stick to it through every micro-decision (chrome / kicker / spacing / accent)?
Evidence to look for:
0–4 Three styles fighting each other. 5–6 One direction but half the elements drift. 7–8 Coherent, occasional drift on edge pages. 9–10 Every element argues for the same thesis.
Can a stranger figure out what to read first, second, third — without being told?
Evidence to look for:
0–4 Everything shouts. 5–6 Hierarchy works on hero pages but breaks on body. 7–8 Clear tiers, occasional collision. 9–10 Eye moves with zero friction.
The 90/10 stuff — alignment, leading, kerning at large sizes, image framing, foot/chrome polish, edge-case spacing.
Evidence to look for:
grid-2-7-5?frame-img + caption proportions consistent across pages?<br> causing 1-character lines?0–4 Visible tape and string. 5–6 Most pages clean, 1–2 ragged. 7–8 Polished, expert eye finds 2–3 misses. 9–10 Magazine-grade — the kind of detail that makes printed-by-hand typographers nod.
Does the artifact work for its intended use? Click targets, nav, readability at presentation distance, copy-paste-ability for code blocks, mobile fallback if relevant.
Evidence to look for:
0–4 Visually fine but doesn't accomplish its job. 5–6 Core flow works, edge cases broken. 7–8 Robust through normal use. 9–10 Defensively engineered — handles iframe / fullscreen / paste / print without flinching.
Does this push past the median? Is there one element that makes people lean in?
Evidence to look for:
0–4 Generic AI-slop median. 5–6 Competent and unmemorable. 7–8 One memorable moment, the rest solid. 9–10 Multiple moves you'd steal — but each one obviously serves the thesis.
Three modes:
<artifact>.If multiple HTML files exist, ask which one (don't review all).
Skim the entire <style>, then read 6–8 representative content
blocks. Do not score from frontmatter alone. The score depends on
executed design, not declared intent.
For each of the 5 dimensions, write the score and a 30–80 word evidence paragraph that names specific elements. Use line numbers, class names, page numbers.
Example:
Dimension: Detail execution
Score: 6 / 10
Evidence: Stat-cards on page 3 align cleanly (grid-6, 3×2), but on
page 8 the right column foot sits 2vh higher than the left because
.callout has 3vh top margin while the figure doesn't. Image captions
use mono on page 5 but sans on page 7 — pick one.

Use the active DESIGN.md tokens if one exists; otherwise default to a neutral light theme (off-white background, near-black text, one accent for radar fill).

</artifact>
One sentence before the artifact ("Reviewed X across 5 dimensions, see
report below.") and stop after </artifact> — do not paraphrase
the report in chat; the user will read the artifact.
