## What it does

The skill parses raw research files from card sorting exercises, such as spreadsheets or participant exports. It checks the study setup, noting whether the sort was open or closed alongside the participant count. The agent then calculates grouping frequencies and builds a similarity matrix.

Cards with low agreement get flagged immediately. Based on participant mental models, the skill suggests category labels and outlines next steps, such as tree testing or design iterations. It clarifies messy feedback without manual tallying.

Turning these groupings into a complete site structure requires the companion skill `information-architecture`. This skill stays focused on analyzing sort evidence, so feeding it incomplete study data will cause the agent to pause for clarification.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill card-sort-analysis -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill card-sort-analysis -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill card-sort-analysis -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills card-sort-analysis
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill card-sort-analysis -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path design-research/skills/card-sort-analysis
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill card-sort-analysis -a opencode
```

### Claude.ai

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

## When to use it
- calculate item grouping frequencies in a similarity matrix
- derive navigation categories from open or closed card sort data
- isolate ambiguous cards that participants categorized inconsistently
- outline follow-up studies like tree testing

## Example prompts
- Analyze the open card sort data in sort-results.csv and build a similarity matrix
- Review our closed card sort spreadsheet and suggest navigation categories
- Highlight ambiguous cards from the latest card sort study and propose next steps

# Card Sort Analysis

Analyze card sorting results to inform information architecture decisions.

## Context

You are a UX researcher analyzing card sort data for $ARGUMENTS. If the user provides files (card sort results, spreadsheets), read them first.

## Instructions

1. **Understand the study**: Confirm methodology (open vs closed), number of participants, and card set.
2. **Analyze groupings**: Identify common category patterns and naming conventions.
3. **Create a similarity matrix**: Show how frequently items were grouped together.
4. **Recommend IA structure**: Propose navigation categories based on user mental models.
5. **Flag ambiguous items**: Highlight cards that were inconsistently categorized.
6. **Suggest next steps**: Tree testing, additional research, or design iterations.
7. Present findings with clear recommendations for navigation and content organization.
