# UX Writing
Write clear, concise, user-centered interface copy (UX text/microcopy) for digital products and experiences. This skill provides frameworks, patterns, and best practices for creating text that helps users accomplish their goals.
## When to Use This Skill
Use this skill when:
- Writing interface copy (buttons, labels, titles, messages, forms)
- Editing existing UX text for clarity and effectiveness
- Creating error messages, notifications, or success messages
- Designing conversational flows or onboarding experiences
- Establishing voice and tone for a product
- Auditing product content for consistency and usability
## Core UX Writing Principles
### The Four Quality Standards
Every piece of UX text should be:
1. **Purposeful** — Helps users or the business achieve goals
2. **Concise** — Uses the fewest words possible without losing meaning
3. **Conversational** — Sounds natural and human, not robotic
4. **Clear** — Unambiguous, accurate, and easy to understand
### Key Best Practices
**Conciseness**
- Use 40-60 characters per line maximum
- Every word must have a job
- Break dense text into scannable chunks
- Front-load important information
- Eliminate deadwood phrases ("in order to" → "to", "due to the fact that" → "because", "at this point in time" → "now")
- Replace phrasal verbs with direct verbs ("find out" → "discover", "set up" → "configure", "carry out" → "perform")
- Avoid stacking modifiers — one adjective is usually enough
**Clarity**
- Use plain language (7th grade reading level for general, 10th for professional)
- Avoid jargon, idioms, and technical terms
- Use consistent terminology throughout
- Choose meaningful, specific verbs
- Avoid discriminatory or exclusionary language (gendered defaults, ableist idioms, culturally specific metaphors)
**Conversational Tone**
- Write how you speak
- Use active voice 85% of the time
- Include prepositions and articles
- Avoid robotic phrasing
**User-Centered**
- Focus on user benefits, not features
- Anticipate and answer user questions
- Use second-person ("you") language
- Match user's language and mental models
## UX Text Patterns
Apply these common patterns for interface elements.
### Titles
- **Purpose**: Orient users to where they are
- **Format**: Noun phrases. **Page titles, modal/dialog titles, and menu/navigation items use title case** (see Capitalization below for title-case mechanics). **Lower-level headings (H3+), figure captions, callouts, and table titles use sentence case.**
- **Types**: Brand titles, content titles, category titles, task titles
- **Examples**:
- Page title (title case): "Account Settings", "Your Library", "Run Payroll"
- Lower-level heading (sentence case): "Recent activity", "Bank account details", "Tax withholdings"
### Buttons and Links
- **Purpose**: Enable users to take action
- **Format**: Active imperative verbs, sentence case
- **Pattern**: `[Verb] [object]`
- **Examples**: "Save changes", "Delete account", "View details"
- **Avoid**: Generic labels like "OK", "Submit", "Click here"
### Error Messages
- **Purpose**: Explain problem and provide solution
- **Format**: Empathetic, clear, actionable
- **Pattern**: `[What failed]. [Why/context]. [What to do].`
**Error Message Types**
**Validation Errors (Inline)**
- Show as user completes field or on blur
- Brief, specific guidance to correct input
- Pattern: `[Field] [specific requirement]`
- Examples:
- "Email must include @"
- "Password must be at least 8 characters"
- "Choose a date in the future"
- Timing: Real-time or on field exit
- Location: Below or beside the field
**System Errors (Modal/Banner)**
- Show when backend operations fail
- Explain what happened and why
- Pattern: `[Action failed]. [Likely cause]. [Recovery step].`
- Examples:
- "Payment failed. Your card was declined. Try a different payment method."
- "Couldn't save changes. Connection lost. Reconnect and try again."
- "Upload failed. File is too large. Choose a file under 10MB."
- Timing: Immediately after failure
- Location: Modal dialog or prominent banner
**Blocking Errors (Full-screen)**
- Prevent continued use until resolved
- Clear explanation of blocker and resolution
- Pattern: `[What's blocked]. [Why]. [Specific action needed].`
- Examples:
- "Update required. This version is no longer supported. Update now to continue."
- "Subscription expired. Your account is paused. Renew subscription to restore access."
- "Verification needed. Confirm your email to access features. Check your inbox."
- Timing: On app launch or feature access
- Location: Full screen or large modal
**Permission Errors**
- Explain benefit before requesting permission
- Pattern: `[User benefit]. [Permission needed].`
- Examples:
- "Get notified when orders ship. Enable notifications."
- "Find nearby stores. Allow location access."
- "Back up your photos. Grant storage permission."
- Timing: When feature is first used
- Location: In context of the feature
**What to Avoid**
- Technical codes without explanation ("Error 403")
- Blame language ("invalid input", "illegal character")
- Robotic tone ("An error has occurred")
- Dead ends (error with no recovery path)
- Vague causes ("Something went wrong")
### Success Messages
- **Purpose**: Confirm action completion
- **Format**: Past tense, specific, encouraging
- **Pattern**: `[Action] [result/benefit]`
- **Examples**: "Changes saved", "Email sent", "Profile updated"
### Empty States
- **Purpose**: Guide users when content is absent
- **Types**: First-use, user-cleared, error/no results
- **Format**: Explanation + CTA to populate
- **Example**: "No messages yet. Start a conversation to connect with your team."
### Form Fields
- **Labels**: Clear noun phrases describing input ("Email address", "Phone number")
- **Instructions**: Verb-first, explain why information is needed
- **Placeholder**: Use sparingly, only for standard inputs like "name@example.com"
- **Helper text**: Static, on-demand, or automatic based on importance
### Notifications
- **Purpose**: Deliver timely, valuable information
- **Types**: Action-required (intrusive), Passive (less intrusive)
- **Format**: Verb-first title + contextual description
- **Example**: "Update required. Install the latest version to continue."
## Formatting & Style Conventions
### Capitalization
- **Sentence case** (default): Body text, descriptions, helper text, error messages, success messages, tooltips, placeholder text, **button labels**, lower-level (H3+) headings, figure captions, callouts, table titles
- **Title case**: Page titles, modal/dialog titles, menu and navigation items, form field labels
- **All-caps**: Reserved for **short overline / eyebrow labels** (≤3 words) that sit above a heading or metric — e.g., stat-card section headers like `EMPLOYEES`, `TOTAL PAY`, `LAST UPDATED`, category tags over KPI values — and for **acronyms** (`PDF`, `URL`, `API`, `EIN`, `SSN`). Trimble's own product surfaces use this treatment for short category overlines; it's an intentional typographic signal, not shouting. **Do not** use all-caps for prose, button labels, error messages, page titles, tabs/menu labels, or any string longer than ~3 words — beyond that length readability drops sharply and it reads as shouting.
**Title case mechanics** (applies wherever title case is used):
- Capitalize the first and last word of the title regardless of part of speech.
- Capitalize all adjectives, adverbs, and nouns.
- Capitalize all pronouns (including "it").
- Capitalize all verbs, including the verb "to be" in all forms (is, are, was, has been, etc.).
- Capitalize "no", "not", and the interjection "O".
- Do **not** capitalize articles ("a", "an", "the") unless first or last in the title.
- Do **not** capitalize coordinating conjunctions ("and", "or", "nor", "but", "for", "yet", "so") unless first or last in the title.
- Do **not** capitalize "to" (with or without an infinitive) unless first or last in the title.
- Do **not** capitalize prepositions (e.g., "in", "on", "at", "by", "of", "with") unless first or last in the title.
Examples:
- "Run Payroll for the Pay Period"
- "Add a New Employee"
- "How to File Quarterly Taxes"
**Lista interpretations of edge cases:**
- **"Coming soon"** is the canonical future-feature label everywhere it appears (badges, callouts, copy). Even when used in a title-cased context, write it sentence case per the `lista-ui-conventions` rule. Do not expose milestone granularity ("Coming at Beta", "Coming at GA") in user-facing strings.
- **Dropdown action items** (imperative-verb items inside a button-triggered menu, e.g. `"Add employee"`, `"See payroll runs"`, `"Export report"`) are treated as **buttons → sentence case**, not as static navigation menu items. Prism's "menu items use title case" rule applies to **navigational** menus (side nav, breadcrumbs, top-level nav links pointing to pages), not action menus.
- **Buttons that reference a named page** (e.g. `"Go to Setup Wizard"`, `"Back to Payroll Hub"`, `"Open Time Review"`) **preserve the page name's title case** while the surrounding button copy stays sentence case. The page name is a proper noun in this context.
### Numbers and Dates
- Use numerals, not words ("12" not "twelve") — saves space and scans faster.
- Spell out the month in dates: "August 5, 2025" or "5 August 2025" — never "8/5/2025" or "8.5.2025" (ambiguous across locales).
- Spell out day of the week and month; abbreviate only when space is constrained (e.g., tables, mobile): "Sat., Jan. 24".
- **Avoid ordinal suffixes** in dates: write "August 5", not "August 5th"; write "May 1", not "May 1st".
- **Year ranges** use a hyphen with the full year on both sides: "2015-2016", not "2015-16" and not "2015 to 2016".
### Tense
- Prefer past tense over present perfect for status messages: "File uploaded" not "File has been uploaded"
- Present perfect adds words without adding meaning in most UI contexts
### Abbreviations
- Only use abbreviations your users will immediately understand (common: PDF, URL, ID)
- Spell out on first use if there's any doubt, then abbreviate after: "application programming interface (API)"
- Latin abbreviations (e.g., i.e., etc.) — use proper punctuation: period after each letter, comma before and after in a sentence
- When in doubt, spell it out
## Voice and Tone
### Voice (Consistent Brand Personality)
Voice is the consistent personality of the product. Establish voice using:
- **Concepts**: 3-5 key brand principles/values
- **Voice characteristics**: Descriptive adjectives for each concept
- **Do/Don't examples**: Concrete examples showing voice in action
See references/voice-chart-template.md for creating a voice chart.
### Tone (Adaptive to Context)
Tone is how voice adapts to specific situations. While voice remains constant, tone shifts based on user context and emotional state.
**Tone Variables**
- **Purpose**: Why user is seeing this text (information, action, confirmation)
- **Context**: What user is trying to do (learning, completing task, recovering from error)
- **Emotional state**: How user likely feels (fruSkill source recorded
