UX research and design critique for your agent: research plans, personas, storyboards, heuristic reviews and measured design forensics, with at most three priority actions.
UX research and design critique, the reasoning BEFORE a wireframe and the judgment AFTER a build.
Why use it
- Design decisions defended by taste instead of evidence.
- "Analyze this design" answered with guessed hex codes and invented font sizes.
- A reviewer who recites all ten heuristics and prioritizes nothing.
What it does
research, pick the method that fits the question × product stage, and mine the free evidence first.personas, 2-4 relevance-tested personas, each carrying its provenance (grounded, or clearly labelled proto).storyboard, one persona · one scenario · one path, with an emotion per panel.heuristics, Nielsen H1-H10 applied selectively: critique, or design guidance handed to the designer.review, the combined lens (usability · cognitive load/conversion · craft · a11y · AI-product) with a verdict and max 3 priority actions.analysis, design forensics: measured hexes, type scale, spacing ladder, contrast pairs, composition metrics, tokens.
Benefits
- Numbers, not opinions. Every hex, size and ratio is measured, anything inferred is labelled.
- Findings you can act on today: 3-5 issues, each with its cost, and max 3 priority actions.
- Know who you're designing for before the first wireframe, and whether the build served them after.
- No turf wars. It critiques and routes; it never touches your design system or your code.

# ux-expert
> UX research and design critique — the reasoning BEFORE a wireframe and the judgment AFTER a build.
**Plugin:** `web-dev` — `/plugin install web-dev@hasbrains-agent-kit`
## Why use it
- Design decisions defended by taste instead of evidence.
- "Analyze this design" answered with guessed hex codes and invented font sizes.
- A reviewer who recites all ten heuristics and prioritizes nothing.
## What it does
- `research` — pick the method that fits the question × product stage, and mine the free evidence first.
- `personas` — 2-4 relevance-tested personas, each carrying its provenance (grounded, or clearly labelled proto).
- `storyboard` — one persona · one scenario · one path, with an emotion per panel.
- `heuristics` — Nielsen H1-H10 applied selectively: critique, or design guidance handed to the designer.
- `review` — the combined lens (usability · cognitive load/conversion · craft · a11y · AI-product) with a verdict and max 3 priority actions.
- `analysis` — design forensics: measured hexes, type scale, spacing ladder, contrast pairs, composition metrics, tokens.
## Benefits
- **Numbers, not opinions.** Every hex, size and ratio is measured — anything inferred is labelled.
- **Findings you can act on today:** 3-5 issues, each with its cost, and max 3 priority actions.
- **Know who you're designing for** before the first wireframe — and whether the build served them after.
- **No turf wars.** It critiques and routes; it never touches your design system or your code.
