Claude Code: type 'ultrathink' while it's working

A 12-second silent, sped-up terminal recording from @daniel_mac8, plausibly genuine. Verdict: a real small tip; low to moderate skill, needs Claude Code in a terminal but no coding. Typing ultrathink while Claude is mid-task makes Claude Code show 'Deeper reasoning requested for this turn' straight away. The clip shows only that acknowledgement, not better answers, and the ctrl+x step in his post wasn't needed to trigger it. (He was running the /be-ambitious skill from the Skills section.)

Try this

  1. Run a skill by slash command and see it expand to its anthropic-skills: name. 0:00
  2. Use shift+tab to cycle auto mode. 0:00
  3. Keep typing while Claude works on a turn. 0:05
  4. Type ultrathink mid-turn and look for 'Deeper reasoning requested for this turn'. 0:08
  5. Note that mid-turn text becomes a queued message. 0:11
  6. Press Up to edit a queued message. 0:11
  7. Press ctrl+x then ctrl+s to send a queued message straight away. 0:11
