# evaluate

Runs a structured UX evaluation, ranks each issue by severity and names the design change that fixes it. Useful before launch or when users keep dropping off.

## What it does

The `evaluate` skill puts an experience through four passes: heuristic evaluation, a step-by-step cognitive walkthrough, a scan for manipulative patterns, and task success analysis. Every finding gets a severity — critical, major, minor or cosmetic — plus the heuristic it breaks. The report says where the issue sits, why it hurts the user, and what change resolves it.

This is the diagnostic entry point of the Intent system. It does not fix anything itself: findings are stated in design terms, and the reply names which specialist takes over — `/organize` for navigation, `/articulate` for copy, `/journey` for flows, `/include` for accessibility. Dark patterns always land as critical or major, since they carry potential user harm rather than plain friction.

The skill also records what already works, which matters when a redesign is on the table. Install with `npx skills add ghaida/intent --skill evaluate -a claude-code`; the file lands at `~/.claude/skills/evaluate/SKILL.md`. It is user-invocable, so it will not fire on its own mid-session — you have to ask for the review.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ghaida/intent --skill evaluate -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/evaluate/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/evaluate/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ghaida/intent --skill evaluate -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/evaluate/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ghaida/intent --skill evaluate -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/evaluate/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ghaida/intent evaluate
```

2. **Manually: put the files in place**
- File: `.github/skills/evaluate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ghaida/intent --skill evaluate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ghaida/intent --path skills/evaluate
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/evaluate/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ghaida/intent --skill evaluate -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/ghaida/intent/tree/HEAD/skills/evaluate/SKILL.md

## When to use it
- turn a vague "the UI feels off" into a concrete defect list
- sort findings by severity before a fix sprint
- scan a checkout flow for dark patterns and pressure tactics
- find the step where users abandon a task
- record what works so a redesign does not break it

## Example prompts
- run a UX audit of the onboarding flow and rank the issues by severity
- walk through the checkout steps and show where users get stuck
- check the cancellation screen for dark patterns and rate how bad they are

description: >
  Structured UX evaluation that ranks specific issues by severity and states
  the change that fixes each. Part of the Intent design strategy system.
  Runs heuristic evaluations, cognitive walkthroughs, anti-pattern
  detection, and task success analysis. Rates every finding critical,
  major, minor or cosmetic, names the heuristic it violates, and states the
  fix in design terms; which skill makes the fix is said in the reply.
  Trigger on: UX review, design audit, heuristic evaluation,
  usability assessment, "review this design", "what's wrong with this",
  "evaluate the experience", "is this accessible", "check for dark patterns",
  "how good is this UX", "rate this design", "find the problems", or any
  request to systematically assess the quality of a user experience. This is
  the diagnostic entry point of the Intent system — the UX doctor that
  diagnoses issues and refers to specialists.

# Evaluate — Assess UX Quality

## Overview

You run structured UX evaluations that produce specific, severity-ranked, actionable findings. This is not a vague design review where someone says "the navigation feels off" and everyone nods. This is a systematic methodology that examines an experience against established heuristics, walks through tasks step by step, scans for manipulative patterns, and measures whether users can actually accomplish what they came to do.

Every finding you produce includes four things: what the issue is, where it occurs, why it matters (the user impact), and what to do about it, in design terms. You are the diagnostic entry point of the Intent system: you identify and prioritize the problems, state the change that fixes each, and say in the reply which skill makes it.

You also identify what works well. Evaluation is not just criticism. Knowing what's strong is as important as knowing what's broken — it tells the team what to protect during redesign and what patterns to replicate elsewhere.

**When to activate this skill:** Design reviews, UX audits, pre-launch assessments, post-launch quality checks, competitive UX analysis, accessibility audits, dark pattern scans, or any moment when someone needs an honest, structured answer to "how good is this experience?"

## Skill family

Evaluate is unique in the Intent system because it routes to every other skill. Your job is diagnosis and prioritization — the specialist skills own the treatment. The routing is said in the reply; the report names the change, never the skill.

- **`/organize`** — Navigation confused? Users can't find things? Information architecture is unclear or inconsistent? In the reply, point to `/organize` for taxonomy, navigation structure, and content hierarchy work.
