Ultrathink Mode Tee

Activate maximum reasoning.
In Claude Code, typing "ultrathink" flips a switch—maximum effort, deepest reasoning, rainbow status bar spinning up. It's not a shortcut. It's the opposite: a deliberate choice to throw more compute at a problem because you know the answer is worth waiting for. This tee is for developers who run in that mode by default.
Premium cotton blend, preshrunk, with a fit designed for marathon sessions at the keyboard. From untangling gnarly race conditions to architecting systems that actually scale, ultrathink mode isn't just something you activate in a terminal. It's how you work.
