I ran the same UI brief 6 times with and without the frontend-design plugin

A small test of the official frontend-design plugin on one landing-hero brief, six runs with it and six without. Explains that the plugin is a single model-invoked skill with no slash command, which plans a palette, type pairing and one signature element before writing code. A 29 July re-run withdrew two of the original claims; the remaining finding is that runs without the plugin repeated each other.

Disclosure Self-scored, six runs per arm. In the comments the author says they draft with Claude and that the runs and numbers are their own.
