The full review
Stopped by us. Stopped by us (box row cap reached (2700s); stopped by the box lane so the run ships as partial); not a model failure.

The exact prompt
as run, 1,403 characters. Every result for this prompt
Build a real-time 3D diorama in Three.js of a small, cosy island valley with a clear mountain stream running through it (one HTML file, CDN imports only, no external assets or textures; everything procedural). The stream is the hero: shallow, crystal-clear water you can see the pebbled bed through, with animated flow, caustic light patterns on the stones underneath, sparkling sun glints on the surface, foam and small rapids where it runs over rocks, and soft rounded river boulders of varied size partly submerged with wet darkening at the waterline. Around it: lush stylised grass and ferns that sway, a few broad-leaf trees, wildflowers, an arched stone bridge or culvert the stream flows through, stepping stones, and a small timber cottage on the bank whose windows glow warmly at night. Lighting presets in a small on-screen pill menu: Morning, Afternoon, Sunset, Blue hour, Night (night shows moonlight on the water and lit windows); transitions animate smoothly. Camera: a slow cinematic auto-fly along the stream by default, free orbit on drag, and a top-down view toggle. Ambient life: drifting petals or fireflies at night, small fish darting under the surface. Gentle procedural water ambience via Web Audio after the first click, with a mute toggle. A title card in the corner names the place. Target 60 fps on a mid-range laptop; include a quality toggle (low/high). Deliver index.html.

OpenCode 1.18.35 reported its own total; token counts x list prices shown beside it. The harness reports reasoning tokens separately from output; here output includes them (293 visible + 548 reasoning), and both bill at the output rate.

Run notes
- frozen prompt (written): core requirements sha256 e84a7975916b, full harness prompt sha256 e84a7975916b; exact prompt text used by the existing harness rows of this test on the runs branch (copied from threejs_island_stream_diorama__claude-code__opus-5-5-high__attempt1/meta.json, sha256 verified); Beta h
- no TUI: the harness ran in its non-interactive mode, so there are no TUI screenshots; the timelapse is built from version renders only
- OpenCode config (providers only, permission allow-all except question; no agents/instructions) + both default skill kits in xdg/config/opencode/skill (skills=on)
- infra retries: 0
- in the published transcript the sandbox HOME directory is shown as <HOME>
- skills=on: 54 skills installed in the harness skill directory before launch (video-33 remotion-dev/skills + heygen-com/hyperframes@0b5db9da + f; web-threejs-21 [redacted]/ai-AI Model Reviewer skills/ (alpha/mr-homebar)@7521074d98c9).
- Mode: headless run mode (opencode run --format json), inside bubblewrap sandbox
- Isolation audit: none
- Status: stopped by us. Stopped at the row cap (45 min) before the harness declared it finished; it had not written an index.html by then, so there is no page to show.
- Skills on: the run had 54 skills installed (33 video + 21 web/Three.js), as its meta records.
- Kimi K3 served via Fireworks (OpenCode provider fireworks-ai).
