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.
Aggregate the 5 evidence paragraphs into:
display:flex for grid on page 4 to
fix the column drift").Build a single file:
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 identifier="critique-<artifact-slug>" type="text/html" title="Critique · <Artifact Title>">
<!doctype html>
<html>...</html>
</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.
Alternatives
coreyhaines31/marketingskills
When the user wants to plan, design, or implement an A/B test or experiment, or build a growth experimentation program. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," "how long should I run this test," "growth experiments," "experiment velocity," "experiment backlog," "ICE score," "experimentation program
coreyhaines31/marketingskills
When the user wants to reduce churn, build cancellation flows, set up save offers, recover failed payments, or implement retention strategies. Also use when the user mentions 'churn,' 'cancel flow,' 'offboarding,' 'save offer,' 'dunning,' 'failed payment recovery,' 'win-back,' 'retention,' 'exit survey,' 'pause subscription,' 'involuntary churn,' 'people keep canceling,' 'churn rate is too high,' 'how do I keep users,' or 'customers are leaving.' Use this whenever someone is losing subscribers o

Use when the user says "review the design", "check the UI", or wants a comprehensive UI/UX review. Uses a 7-phase methodology covering interaction, responsiveness, accessibility, and more.
