**Creating an index** I need to focus on creating an index, and that means I should inspect the files first. It's essential to have a clear understanding of the files at hand in order to build the index effectively. I want to make sure everything is organized properly, so I'm going to take a careful look to see what's there. This will help me ensure that I capture all the necessary information. Alright, let's get started!

**Planning scene creation** I need to create an index that satisfies the requirements, and I might want to test the syntax. I plan to build a polished scene using Three.js, including a rotating icosahedron, two colored point lights, and orbit-style auto-rotation. Since OrbitControls are unavailable in the core library, I could implement auto orbit along with pointer drag and wheel functionalities. The user wants orbit-style auto-rotation, and I'll need to ensure no external scripts are used. I'll create it via write.

**Inspecting syntax and constructor** I think I need to check the syntax in my browser, but it’s unavailable right now. I should ensure that the PointLight constructor signature is alright. Hmm, is the outputColorSpace possibly using an older version? If it’s three minutes old, it’s likely modern. I have to satisfy myself with the check. Maybe I could run a grep command to look deeper into the matter. Let's see what I find!

Created `/tmp/ws/index.html` with: - Full-screen Three.js scene - Rotating, faceted icosahedron - Cyan and magenta point lights - Auto-orbiting camera - Interactive drag-to-orbit and scroll-to-zoom controls - Subtle starfield background - Inline CSS and JavaScript - Local `three.min.js` script reference only

EVALUATION
Rotating icosahedron with blue/pink point lights and subtle starfield; responds to drag/wheel/keys with rotation and zoom changes.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
