Show HN: Motion Debugger – A browser critic for AI slop
TL;DR
Built a tool to unslop UI and add cool motion. It's an open-source workflow for coding agents, using Chromium to inspect the rendered site, catch broken animations, overlapping elements, layout issues, and other visual problems, then gives the agent feedback to fix them. a/b tests are in the repo. ycombinator.
Nauti's Take
Run Motion Debugger against a real interface with deliberately broken animations and measure three things: whether the agent finds the issues consistently, explains the cause correctly, and avoids damaging working areas during the fix. The Hacker News post has one point and no comments, so the tool’s broader impact is still unverified.
The useful benchmark is its error rate in your own UI workflow, with the repository demo as a starting signal.
