Motion Debugger launches browser review tool
Understand this story
ShadowKingYT444 launches Motion Debugger, providing two capabilities for coding agents: the premium-motion skill, and the motion-debugger critique browser review tool. The tool lets agents record pages in Chromium, inspect motion and layout defects, and output findings with fix suggestions. The review tool writes a contact sheet to .motion-critique/ and explains which issues have been fixed since the last run, which are new, and which remain. It only opens local pages that require no credentials (localhost, 127.0.0.1 and local files), does not import the user's browser profile, and keeps recordings within the project folder. For installation, the CLI and npx commands require Node.js 22 or higher, while the git method only requires git. The tool does not write anything when these requirements are missing, and preserves the user's existing settings.

- Hacker News AIShow HN: Motion Debugger – A browser critic for AI slop
Motion Debugger is a CLI and agent skill that critiques local pages in Chromium, recording entrances, scrolling, hovers, phone layout and reduced motion, then returns ranked fixes with screenshots. Its premium-motion skill runs an upgrade pipeline that keeps facts, links and forms while rebuilding layout and motion on a GSAP/ScrollTrigger/SplitText/Lenis stack or Motion in React. The author reports four single-run upgrades and a blinded four-pair A/B study where judges preferred the plugin's sites in all eight judgments, noting the sample is too small for significance.
