- Replace fictional `/think` example with official `ultrathink` keyword - Fix Q4 options: `/think` → `/effort max`, `--thinking` → `ultrathink` - Fix Q5: correct the answer that "ultrathink" DOES trigger deep reasoning - Sync changes across English, Ukrainian, and Vietnamese translations Background: `/think` is not a valid slash command in Claude Code (verified against official commands reference at code.claude.com/docs/en/commands). The correct way to trigger deep reasoning for a single response is to include "ultrathink" in the prompt.
