## What it does

The skill guides you through planning a longitudinal study, for when behaviour unfolds over days or weeks. You start with research goals, then build the plan: duration, participants, entry prompts, capture methods, a check-in schedule and onboarding.

Inside is a four-step instruction set plus an analysis framework — how to code, theme and synthesise entries across participants. Attrition gets its own step, since drop-off in diary studies is expected. For a single-session study the author points you to `usability-test-plan` instead.

It runs in Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode. Install goes through `npx skills add` or `gh skill install`, depending on the platform.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill diary-study-plan -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill diary-study-plan -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill diary-study-plan -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills diary-study-plan
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill diary-study-plan -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path design-research/skills/diary-study-plan
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill diary-study-plan -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/Owl-Listener/designer-skills/tree/HEAD/design-research/skills/diary-study-plan/SKILL.md

## When to use it
- design a multi-week diary study
- pick entry prompts and cadence for participants
- write screening criteria and a compensation plan
- build a coding and theming frame across participants
- keep participants engaged until the study ends

## Example prompts
- Plan a 3-week diary study of how people use our app
- Help me write entry prompts and a check-in schedule for a diary study
- Draft the analysis framework for diary study entries

# Diary Study Plan

Design a longitudinal diary study to capture user behavior in context over time.

## Context

You are a UX researcher designing a diary study for $ARGUMENTS.

## Instructions

1. **Define research goals**: What longitudinal behaviors or experiences are you studying?
2. **Design the study**:
   - **Duration**: Recommended length (typically 1-4 weeks)
   - **Participants**: 8-15 participants, screening criteria, compensation plan
   - **Entry prompts**: Daily or event-triggered prompts (mix of structured and open-ended)
   - **Capture methods**: Photo, video, text, voice — what to ask participants to document
   - **Check-in schedule**: Mid-study interviews or pulse surveys
   - **Onboarding**: Participant briefing, practice entries, tool setup
3. **Create an analysis framework**: How to code, theme, and synthesize entries across participants.
4. **Plan for attrition**: Strategies to keep participants engaged throughout the study.
5. Present as a ready-to-execute research plan.
