AI to Widget is an open-source toolkit designed to turn any existing 
web application into one with its own conversational agent — grounded 
in the app's real data, able to take real actions on behalf of the 
user with their own permissions, deployable with a few Claude Code 
slash commands.

The product was not shipped. Instead, this submission is a structured 
postmortem of the 5-day build attempt using Opus 4.7 and Claude Code 
in a spec-driven, constitution-first agentic workflow.

The deliverable is a documented report of 20 incidents across 8 failure 
categories — with timestamps, commit hashes, verbatim evidence, and 
honest attribution (model error, user error, ambiguous spec, or mixed). 
It includes 7 actionable recommendations for Anthropic at the model, 
tooling, and workflow guidance layers.

The hackathon asked builders to push Opus 4.7's limits and find them. 
This report does exactly that — not as a complaint, but as data.
