Open With
A first-run screen that picks your setup path from one question. Built for The First Ninety Seconds — design the opening 90 seconds of a product a stranger has never seen. The question and three branching paths. The interface is deliberately narrow: one path, done properly, rather than a broad surface that half-works at the deadline.

On the clock
What shipped, what didn't
Completed in time
The question and three branching paths.
Unfinished / faked
Two of the three paths dead-end.
Obstacles
Spent too long on the data model and had to build the interface in the last eight minutes.
Lessons learned
Scope down before the timer starts, not at minute 20 when you're already committed.
Process
Prompting approach
Started from a single system prompt describing the user and their constraint, then iterated with the assistant on the Open With data model before writing any interface code. Full prompt log is in the repository under /prompts.
Fairness
Disclosures
Declared by the builder at submission time, visible to judges before scoring.
Judging
Public feedback
Judges' private notes stay private — this is what they chose to say publicly.
Ravi Anand
Head of Design, Tessellate
The concept is interesting but not enough shipped to evaluate it fairly. Scope down harder next time — pick one screen and finish it.
Tomas Eriksen
Developer Advocate, Independent
This needed a working demo path. I could not verify the core claim from what was submitted.
