Fail

Run on 2026-10-19Open the raw answer

The page never starts. The code declares the name “frame” twice — once for the painting’s frame and once for the render loop — which is a syntax error that stops the whole script. The room, the puzzle chain and the inventory were all written, but none of it can run.

Test conditions

Single attempt per test, no retries and no edits afterwards. Run inside a Claude Code agent session, which includes its own system prompt, rather than the raw API.
