Claude Code Asked 5 Questions, Then Built a Site: $0.61 at API Prices

We re-ran our Claude Code tutorial brief on November 1, 2026 (Claude Code 2.1.303 with Opus 5.5, unattended: plan mode, then Accept edits) to build a one-page site for a made-up dog-grooming salon. Before touching any project file, it asked five questions (our brief asked for up to five), including whether the prices were fixed or "from" prices that change with the dog's size. Planning took 28 seconds and the build took 64 seconds for 436 lines. Both steps cost $0.61 at API list prices (on a paid plan it counts toward your usage instead). The catch: nobody was at the keyboard to OK its phone-width screenshot, so it skipped that check and said so.
