## What it does

This skill turns a written screen description into a UX smell report. The taxonomy holds 8 smells split across 6 categories, among them efficiency, feedback, accessibility and consistency. Signals from the text get matched against symptoms, and each smell lands in one of two buckets: confirmed or merely suspected.

Output is JSON only, no narrative. Each finding carries its id, the symptoms that matched, and a severity of critical, warning or suggestion. Detection follows a fixed rule: two matching symptoms, or a single critical one with high confidence, and the smell counts as found. Because the shape never changes, you can parse it in a script.

Richer answers come from uxuiprinciples.com over `curl`: full numbered remediation recipes, time estimates and related principle codes. That path needs `UXUI_API_KEY` set in the environment. Skip the key and the skill falls back to its own taxonomy knowledge and marks the reply with `api_enriched: false`, which means no recipe steps. You get a diagnosis, not a repair plan.

## When to use it
- catch design flaws in a screen description before anyone codes it
- explain why a signup form loses users
- turn a wireframe write-up into a UX issue list
- sort blocking accessibility problems from minor ones
- feed structured audit findings into a script

## Example prompts
- Audit this signup screen description for UX smells: ten fields, one `Continue` button, errors only after submit
- Check the feedback category against my empty-state write-up
- Run the smell taxonomy on this navigation description and give me JSON
