# Claude Opus 5.5 · medium detailed-prompt visual refinement

The lower-right panel explicitly says medium + detailed prompt. The author describes further detailed prompting and checking its own screenshots in the existing medium session, three prompts deep in total: not a new reasoning level, independent blind attempt or one-shot result. The complete six-second final-version recording is preserved; its frames are not extra works. Model labels and attribution remain source-reported, not independently authenticated. The date is verifiable public posting, not inferred generation. Author costs, times and opinions are not museum scores or capability findings.
