I
Calliope
Composition
Judges the architecture of the page — balance, weight, and the placement of every element within the whole.
An Aesthetics Benchmark
TasteBenchCarved standards for machine‑made beauty
Every HTML artifact submitted to TasteBench is measured against nine enduring axes of visual judgment — struck in stone, scored in numbers.

The Muses Grid
Nine Axes, Nine Muses
TasteBench inherits the old division of labor: each muse presides over one facet of taste, and every artifact is weighed against all nine before a verdict is struck.
II
Clio
Hierarchy
Records what matters first. Scores how clearly an artifact orders its own importance for the eye.
III
Erato
Color Harmony
Weighs how hues meet one another — kinship, tension, and the restraint of a considered palette.
IV
Euterpe
Rhythm & Motion
Listens for cadence — the tempo of scroll, transition, and repetition across the artifact.
V
Melpomene
Contrast
Presides over drama — the friction between light and dark, loud and quiet, that gives a page its tension.
VI
Polyhymnia
Typography
Guards the sacred letterform — pairing, scale, and the discipline of a considered type system.
VII
Terpsichore
Whitespace
Dances through negative space, scoring how room to breathe is given — or withheld — around every form.
VIII
Thalia
Texture & Depth
Delights in surface — grain, shadow, and the illusion of relief lifted from a flat plane.
IX
Urania
Cohesion
Surveys the whole sky — whether every choice resolves into one unified, deliberate system.
Method
How a Verdict Is Struck
01
Submit
An HTML artifact is rendered exactly as a browser would render it — no shortcuts, no static screenshots.
02
Measure
Each of the nine muses examines the artifact independently, blind to the others' findings.
03
Weigh
Scores are struck on a 0–100 scale per axis, then carried into a single composite figure.
04
Publish
The verdict is set in the record — reproducible, inspectable, and open to challenge.

Reading The Card
A Composite, Not a Guess
The final figure is never a single model's opinion. It is nine independent readings, carried through a fixed rubric and struck into one number an engineering team can actually act on.
Low scores point directly to the muse responsible — so a middling Euterpe score means motion and rhythm are the fix, not a vague note to "make it prettier."
- Blind Scoring Each axis is judged without sight of the others' verdicts.
- Fixed Rubric The same nine questions, asked of every artifact, every time.
- Full Trace Every score ships with the reasoning carved beneath it.

Nine muses. One composite. A standard of taste that holds still long enough to build against.
