The prompt
Original prompt
Create a Minecraft-inspired browser game in the Minecraft folder. Use similar-looking voxel textures and gameplay while avoiding copied proprietary assets; I actually like Minecraft, so make it feel faithful. The output must be a single self-contained HTML file that plays directly in a browser.
Note
This is the same standardized Minecraft brief the head-to-head collection entries received, so Blockcraft is effectively a sixth Minecraft run.
Recovery status
Model and prompt recovered verbatim from the Claude Code session `536724d2-6c2d-45e5-a8e6-d23cea0aafa9.jsonl` (cwd `luckey-bench-runs`), which switched to `claude-opus-4-8` via `/model` and wrote `Minecraft/index.html` at 2026-07-12T18:12:35Z — matching the file's mtime exactly. No reasoning-effort flag was recorded for the session, so the reasoning level is shown as unknown. This run was previously published as "model unattributed" before the session was located.
Provenance note. Recovered from a Claude Code session that switched to claude-opus-4-8 via /model. It received the same standardized Minecraft brief as the head-to-head collection, so this is effectively a sixth Minecraft run. No reasoning-effort flag was recorded, so the level is unknown; the run was previously published as “model unattributed”.
