ultrathink| — Extended-Thinking Cursor Tee (Claude Code Inside Joke)
For the ones who let the model think longer.
This minimalist black tee features ultrathink| in a soft gradient—an Easter egg for folks who know Claude Code’s “extended thinking” levels. In Anthropic’s best-practices, think → think hard → think harder → ultrathink map to progressively larger “thinking budgets,” with ultrathink being the max. In other words: give the agent more time and it reasons deeper.
Why it slaps
-
Quiet, clever nod to Claude’s extended-thinking mode—instantly recognizable to devs, AI researchers, and terminal goblins.
-
Clean unisex fit, super-soft feel, and durable print for daily wear
-
Works everywhere: stand-up, sprint review, lab, or late-night build
The inside joke, decoded
“ultrathink” is the top prompt in Claude Code’s planning workflow that allocates the highest thinking budget—basically asking the agent to plan more thoroughly before acting. It’s not a different model; it’s your same model spending more time to reason.
Style notes
Pair with denim and headphones for coffee-shop focus—or layer under a blazer for stealth-nerd energy. The trailing cursor says: ready for the next idea.
