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

When the user wants to plan, design, or implement an A/B test or experiment, or build a growth experimentation program. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," "how long should I run this test," "growth experiments," "experiment velocity," "experiment backlog," "ICE score," "experimentation program," or "experiment playbook." Use this whenever someone is comparing two approaches and wants to measure which performs better, or when they want to build a systematic experimentation practice. For tracking implementation, see analytics. For page-level conversion optimization, see cro.

When the user wants to generate, iterate, or scale ad creative — headlines, descriptions, primary text, or full ad variations — for any paid advertising platform. Also use when the user mentions 'ad copy variations,' 'ad creative,' 'generate headlines,' 'RSA headlines,' 'bulk ad copy,' 'ad iterations,' 'creative testing,' 'ad performance optimization,' 'write me some ads,' 'Facebook ad copy,' 'Google ad headlines,' 'LinkedIn ad text,' or 'I need more ad variations.' Use this whenever someone needs to produce ad copy at scale or iterate on existing ads. For campaign strategy and targeting, see ads. For landing page copy, see copywriting.
