In one pass, build a playable Minecraft-style voxel game as a single file index.html using three.js loaded from https://unpkg.com/three@0.160.0/build/three.module.js (ES module import). Requirements: a generated terrain of at least 32x32 columns with at least 3 block types; first-person WASD movement with mouse look (pointer lock); left click breaks the targeted block, right click places a block; number keys 1-3 select block type; a crosshair and a small HUD showing the selected block. No other files.
Task prompt given to the agent (headless, offline, synthetic fixture inputs): In one pass, build a playable Minecraft-style voxel game as a single file index.html using three.js loaded from https://unpkg.com/three@0.160.0/build/three.module.js (ES module import). Requirements: a generated terrain of at least 32x32 columns with at least 3 block types; first-person WASD movement with mouse look (pointer lock); left click breaks the targeted block, right click places a block; number keys 1-3 select block type; a crosshair and a small HUD showing the selected block. No other files. Inspired by https://x.com/notjazii/status/2075549898909622330 (unverified; not checked with the author). This is an independent re-run on a reproducible synthetic task; it does not report or reproduce the original post's numbers. Cost is real Venice spend (paid from DIEM credit), as reported by Venice.
Success criteria: All automated rubric checks pass: imports three@0.160.0 module; pointer lock; WASD; raycast break/place (mouse buttons 0 and 2); block select keys 1-3; crosshair + HUD elements; terrain >=32x32 (size constant); no uncaught console errors in headless Chrome.
Setup notes: Thinking OFF: THINKING OFF rerun 2026-10-15: model id deepseek-v4-1-flash with venice_parameters.disable_thinking=true, max_tokens 16000, per-run cost cap $0.04; otherwise venice-mini-agent v1.2 unchanged. Original (thinking on) score: 1/8 (16k); original result kept as 13-deepseek-v4-1-flash.json. Harness: venice-mini-agent v1.2 via Venice OpenAI-compatible API. Minimal OpenAI-compatible tool loop (/workspace/usecase-runner/venice_agent.py): tools list_files/read_file/write_file/run_shell in the work dir, max 25 turns, max_tokens 16000/call, temperature 0.2, Venice system prompt and web search off, $0.08 per-run cost cap. Identical for all Venice models. Cost source: Venice /api/v1/models model_spec.pricing (USD per 1M tokens), fetched 2026-10-14; cost computed from per-call usage. Paid from Bob's DIEM daily allowance. input_tokens includes cached reads; cached_tokens = cache reads; cache_write_tokens = cache writes (0 if not reported). Single run, no retries; scored automatically (8/8 checks). Runner notes: THINKING OFF rerun 2026-10-15: model id deepseek-v4-1-flash with venice_parameters.disable_thinking=true, max_tokens 16000, per-run cost cap $0.04; otherwise venice-mini-agent v1.2 unchanged. Original (thinking on) score: 1/8 (16k); original result kept as 13-deepseek-v4-1-flash.json. Single run, no retries. Same rubric/score.py as Claude runs. Web disabled. Hit the 25-turn cap with no final message. Every artifact was already written and passed all 8 rubric checks, so this counts as a completed task; the turn cap only cut off the closing summary.

With feet=15.16, feet-0.05=15.11, floor=15, which is air (surface top is y=14, so block occupies y=14, top face at 15). So feet at 15.16 means the player is floating 0.16 above. \n\nThe real issue: `moveAxis('y', ...)` uses `collides` with `minY = floor(py+0.001)`. When falling, the player should stop when feet reach 15.0. Let me trace: the collision check for y uses feet position. Let me look at the step-up bug \u2014 `moveAxis` for 'y' shouldn't step up.
