Error Handling

Failure Modes & Recovery

UNCLEAR_MESSAGE:
  cause: Users don't understand the copy
  detection: high_error_rate || support_tickets
  recovery:
    - Test with users
    - Simplify language
    - Add context or examples

TONE_MISMATCH:
  cause: Copy doesn't match brand voice
  detection: inconsistent_voice || off_brand_language
  recovery:
    - Audit against voice guidelines
    - Rewrite to match tone
    - Update voice documentation

UNHELPFUL_ERROR:
  cause: Error message doesn't help resolve issue
  detection: repeated_errors || user_frustration
  recovery:
    - Add specific remediation steps
    - Provide actionable next steps
    - Offer alternative paths

Fallback Strategies

1. No Brand Guidelines → Use clarity-first, neutral tone
2. Character Limit Exceeded → Prioritize essential info, truncate thoughtfully
3. Localization Issue → Flag cultural considerations, provide notes

Writing Principles

Core Principles

Principle	Description	Example
Clarity	Say exactly what you mean	"Save changes" not "Commit"
Conciseness	Use fewest words possible	"Email" not "Email address"
Usefulness	Help users accomplish goals	Include next steps
Consistency	Same terms throughout	Always "Sign in" or "Log in"
Empathy	Respect user's context	Acknowledge frustration

Voice Spectrum

FORMAL ←─────────────────────────→ CASUAL
     "Submit your application"     "Let's go!"

SERIOUS ←────────────────────────→ PLAYFUL
     "Payment failed"              "Oops! Payment hiccup"

RESPECTFUL ←─────────────────────→ IRREVERENT
     "We appreciate your patience"  "Hang tight!"

Error Message Framework

Structure

[What happened] + [Why it happened] + [What to do next]

Example:
"We couldn't save your changes. The file may be too large.
Try reducing the image size or removing some attachments."

Tone by Severity

Severity	Tone	Example
Critical	Serious, clear	"Unable to process payment. Please try again."
Warning	Helpful, calm	"Your session will expire in 5 minutes."
Info	Friendly, brief	"Changes saved!"
