# UX Writing

Write clear, concise, user-centered interface copy (UX text/microcopy) for digital products and experiences.

## Core UX Writing Principles
### The Four Quality Standards
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:** 40-60 characters per line maximum; every word must have a job.
**Clarity:** plain language (7th grade reading level for general, 10th for professional); avoid jargon.
**Conversational Tone:** write how you speak; active voice ~85% of the time.
**User-Centered:** focus on user benefits, not features; second-person ("you") language.

## UX Text Patterns
### Titles
- Purpose: Orient users to where they are
- Format: Noun phrases, sentence case
- Examples: "Account settings", "Your library", "Create new post"

Description

UX Writing is a standalone skill focused entirely on interface copy, meaning the buttons, labels, error messages, notifications, form hints, empty states, and onboarding text that make up a product's voice but rarely get the same editorial attention as marketing copy. It is built around four quality standards, purposeful, concise, conversational, and clear, and backs each with concrete, checkable guidance rather than vague advice, including a 40-60 character line-length target, a seventh-grade reading level for general audiences, roughly 85 percent active voice, and second-person address.

It provides pattern libraries for common UI text types, such as titles, error messages, empty states, confirmations, and tooltips, each with purpose, format conventions, and examples, plus frameworks for establishing and adapting a product's voice and tone across different contexts. Accessibility is core to the skill rather than an afterthought, with comprehension research and plain-language guidance baked into the same recommendations used for clarity and concision. Use it any time text is being written or edited for an app, website, or software interface, whether drafting new copy, auditing an existing product for consistency, or reviewing UI strings before ship. It is explicitly compatible with any agent supporting the Agent Skills spec, not just Claude.
