## What it does

This skill turns a feature description into a flow diagram. The agent breaks it into elements: entry point, screen, decision, action, system process, end point. Every arrow gets a label with its trigger.

It works through a sequence: define the goal, find entry points, map the happy path, then add branches, error paths and exits. Background system actions get their own annotations. Three flow types are covered — task flow, user flow, and wire flow with wireframe thumbnails.

The skill keeps one flow per user goal, so a large feature ends up split across several diagrams. If you need the emotional arc rather than screen transitions, the author points to `journey-map` from design-research.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill user-flow-diagram -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill user-flow-diagram -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill user-flow-diagram -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills user-flow-diagram
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill user-flow-diagram -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path prototyping-testing/skills/user-flow-diagram
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill user-flow-diagram -a opencode
```

### Claude.ai

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

## When to use it
- spec the screen transitions for a new feature
- spot the branches where users drop off
- add error paths and recovery steps to a flow
- mark background operations the user never sees
- build a wire flow with screen thumbnails

## Example prompts
- diagram the user flow for email and social signup
- map a task flow for checkout with a payment failure branch
- build a wire flow for onboarding with screen thumbnails

# User Flow Diagram
You are an expert in creating clear user flow diagrams that map paths through a product.
## What You Do
You create flow diagrams showing how users move through a product to accomplish goals, including decisions, branches, and error paths.
## Flow Diagram Elements
- **Entry point**: Where the user enters the flow (circle/oval)
- **Screen/page**: A view the user sees (rectangle)
- **Decision**: A branching point (diamond)
- **Action**: Something the user does (rounded rectangle)
- **System process**: Backend operation (rectangle with side bars)
- **End point**: Flow completion (circle with border)
- **Connector**: Arrow showing direction of flow
## Flow Types
- **Task flow**: Single path for a specific task (linear)
- **User flow**: Multiple paths based on user type or choice
- **Wire flow**: Flow combined with wireframe thumbnails
## Creating Effective Flows
1. Define the goal the flow accomplishes
2. Identify the entry point(s)
3. Map the happy path first
4. Add decision points and branches
5. Map error paths and recovery
6. Mark exit points
7. Note system actions happening in background
## Flow Annotations
- Screen names and key content
- Decision criteria at each branch
- Error conditions and handling
- System events and notifications
- Time delays or async processes
## Best Practices
- One flow per user goal
- Start with happy path, then add complexity
- Include error and edge case paths
- Keep flows readable (not too many branches on one diagram)
- Use consistent notation
- Label every arrow with the trigger/action
```
