Inbox Zero Point
Sorts your unread mail into 'reply in one line' and 'everything else'. Built for Cold Open — build a tool that helps someone do the very first step of a task they have been avoiding. Classification and the one-line reply drafts. 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
Classification and the one-line reply drafts.
Unfinished / faked
Read-only — it can't actually send.
Obstacles
Rate limits hit at minute 20 and forced a caching layer I hadn't planned for.
Lessons learned
The demo path is the product. Everything not on it can wait for next time.
Process
Prompting approach
Started from a single system prompt describing the user and their constraint, then iterated with the assistant on the Inbox Zero Point 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.

Good instinct on the problem. I would have liked to see the model doing more of the reasoning rather than formatting output.
