Tested / use as a checklist

3Dviz Pro Max.
A fact checklist, not a speed tool.

An agent skill for Three.js and Blender scenes. We built three small playable games with it in one session. The scenes came out more correct. They did not come out faster.

The verdict

A good fact checklist, not a speed tool. Point your agent at it for science or learning games where correctness matters. Do not expect it to build the scene for you. It is MIT, so it is free to use in games you sell.

Read this with the resultThe games below were built with Claude in one session as a test. They are free to play and are not finished games. Three builders scored the skill 2, 2.5 and 2 out of 5.

Play the three test games

Jelly Molecules: a glassy jelly water molecule, solved, with its bent shape and 104.5 degree angle shown.
Skill score 2 of 5

Jelly Molecules

Chemistry puzzle / click or drag atoms

Build water, methane, ammonia and carbon dioxide from jelly atoms. The success card shows the electron-pair geometry and the molecular shape as two separate readouts, with the measured angle.

Play Jelly Molecules
Exam Room 3: a dark noir exam room with a steel table, a skeleton and a surgical lamp.
Skill score 2.5 of 5

Exam Room 3

Forensic study room / click the hotspots

Walk up to a study skeleton and find five numbered clues. Left and right are kept straight on the skeleton and on the wall X-ray film. No gore.

Play Exam Room 3
Tabletop Circuits: a toy wooden board with switches, colored logic gates and a glowing brass lamp.
Skill score 2 of 5

Tabletop Circuits

Logic puzzle / click the switches

Flip switches on a toy tabletop so the lamp lights. Three levels, up to four gates (AND, OR, XOR, NOT). One evaluator decides every wire and light.

What it is

It is a skill folder your AI agent reads: a Claude Code plugin and a Codex skill. It holds recipes (how to build a kind of thing), knowledge records (rules and checks), kits, and style profiles with numeric starting values for light and color. A search script finds the records that match your request, and a capture script takes screenshots.

The score

GameSkill scoreIn one line
Jelly Molecules2 of 5More trustworthy chemistry, a better success card. Not faster. About a 4 for a narrow water-versus-methane explainer.
Exam Room 32.5 of 5Speed 2, quality 3. Good as a five-minute checklist, not as a build accelerator.
Tabletop Circuits2 of 5One good correctness record and two rules. Retrieval cost about what it saved.

What the skill gave, and what we did by hand

Jelly Molecules with a methane molecule solved, four hydrogen atoms around a carbon.
Jelly Molecules: methane at 109.47 degrees, measured from the settled atom positions.
Exam Room 3 showing a clue card for the absent left sixth rib beside the skeleton.
Exam Room 3: a clue card for the absent left 6th rib.
What the skill gave
Correctness. Real bond angles (water 104.5, methane 109.47) and the habit of measuring them from coordinates. A laterality checklist, so left and right stay straight on the skeleton and on the X-ray film. One evaluator that owns every logic value, so what you see is decided by logic and never by brightness alone. Honest lighting starting numbers, such as warm lamp colors from a kelvin value and a spot cone that suits the throw distance.
What we did by hand
Almost everything else. Each subject had only a recipe or two, and no kit fit any of the three games, so every model was hand-built: the atoms and bonds, the whole skeleton, the toy board and gates. All game logic, level design, controls, phone layouts and the fixes after looking at screenshots were ours. Ammonia and carbon dioxide had no coverage in the skill, so that chemistry came from general knowledge.
Tabletop Circuits level one solved, with the lamp lit.
Tabletop Circuits: level one solved. The lamp glow comes from the evaluator, not a hand-set color.
Tabletop Circuits level three solved, with four logic gates between the switches and the lamp.
Level three: four gates, XOR, NOT, OR and AND, all derived from one logic graph.

Why it was not faster

  • Thin coverage. Each subject had a recipe or two. Searches for ammonia, carbon dioxide and double bonds found nothing usable. There is no recipe for building a skeleton.
  • No kit fit. None of the 22 kits matched a molecule, a skeleton or a circuit, so every model was built by hand.
  • Keyword-only search. It misses on one wrong word. "x-ray lightbox" returned seismic waves, and "surgical lamp" returned a folding desk lamp.
  • Unchecked numbers. Several records say their rendered geometry was never run. The numbers we used checked out, but the skill does not prove it.
  • Overhead. Its ten-step workflow costs more than it saves on a small build.

Windows notes

Use python, not python3
The instructions say python3. On Windows that is often the Microsoft Store stub, so use python.
Scripts need a path workaround
The Python scripts import each other. They fail under python -I unless you add the scripts folder to sys.path first, for example with a small runpy wrapper. This is not documented.
Do not clone the whole repo
A full git clone fails on Windows path length, because of its evidence folder. Clone sparse with only skills/ and examples/.
Screenshots need Playwright
capture.py needs Python Playwright. We did not use it; we captured with our own scripts.

About the three games

The games were built with Claude in one session as a test. They are free to play and are not finished games. Each runs three.js 0.180.0 served from this site, so they make no requests to outside sites. They were checked in headless Chrome only: a real graphics card and touch screens are untested.

Limits and cautions
Exam Room 3 clue text
The case is fiction, but the anatomy was checked against published anatomy and forensic sources on 2026-11-14. Age clues are written as broad hints, because pelvis, spine and skull signs give wide ranges, not numbers. It is a game, not a medical or forensic reference.
Jelly Molecules
Ammonia and carbon dioxide are from general chemistry, not certified by the skill. Lone-pair directions are schematic.
Scope
One session, three subjects, one builder each. A subject with a matching kit, such as a cottage, a tree or a creature, might score higher.
