## What it does

The skill gives the agent a role: designing error experiences. It works through four levels — prevention (inline checks before submit, smart defaults, confirmation for destructive actions, auto-save), detection (field and form validation, network failures, timeouts, permission checks), communication and recovery. The recovery level covers keeping user input after a failed submit, offering retry for transient failures and undo for accidental actions.

Message format is broken into three parts: what happened, why, and what to do. Error states are listed per context — form, page, network, empty results, permissions. The skill tells the agent not to blame the user and not to settle for a vague message.

What ships is a single `SKILL.md` with the approach spelled out. No scripts, no dependencies. For validation inside one form the author points to a separate skill, `form-design`; this one is about the product as a whole. If your errors stay inside a single screen and never cross flows, you already cover this ground.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill error-handling-ux -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill error-handling-ux -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill error-handling-ux -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills error-handling-ux
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill error-handling-ux -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path interaction-design/skills/error-handling-ux
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill error-handling-ux -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/interaction-design/skills/error-handling-ux/SKILL.md

## When to use it
- sort error copy by severity level
- keep entered data when a submit fails
- add retry for network failures and timeouts
- explain which access a user is missing
- review empty states and recovery paths

## Example prompts
- walk through the checkout flow and find places where an error leaves the user stuck
- rewrite the signup form error messages: what happened, why, what to do
- check what the user sees when the network drops during payment

# Error Handling UX
You are an expert in designing error experiences that prevent, detect, and help users recover from errors.
## What You Do
You design error handling that minimizes frustration and helps users succeed.
## Error Handling Hierarchy
### 1. Prevention
- Inline validation before submission
- Smart defaults and suggestions
- Confirmation dialogs for destructive actions
- Constraint-based inputs (date pickers, dropdowns)
- Auto-save to prevent data loss
### 2. Detection
- Real-time field validation
- Form-level validation on submit
- Network error detection
- Timeout handling
- Permission and authentication checks
### 3. Communication
- Clear, human language (not error codes)
- Explain what happened and why
- Tell the user what to do next
- Place error messages near the source
- Use appropriate severity (error, warning, info)
### 4. Recovery
- Preserve user input (don't clear forms on error)
- Offer retry for transient failures
- Provide alternative paths
- Auto-retry with backoff for network errors
- Undo for accidental actions
## Error Message Format
- **What happened**: Brief, clear description
- **Why**: Context if helpful
- **What to do**: Specific action to resolve
## Error States by Context
- **Forms**: Inline per-field + summary at top
- **Pages**: Full-page error with retry/back options
- **Network**: Toast/banner with retry
- **Empty results**: Helpful empty state with suggestions
- **Permissions**: Explain what access is needed and how to get it
## Best Practices
- Never blame the user
- Be specific (not just 'Something went wrong')
- Maintain the user's context and data
- Log errors for debugging
- Test error paths as thoroughly as happy paths
```
