ux-writing

ux-writing is a skill for Claude Code from PrabhdeepSingh/claude-plugins. It costs 95 tokens per session (1,953 once invoked), scanned A, original, MIT.

Guidance for writing the words people see while using a product, such as button labels, error messages, settings, placeholders, and empty states.

In plain words
What is it for?
Use it when writing or reviewing user-facing interface text, including controls, forms, errors, settings, and no-content screens.
Why use it?
It helps users understand what actions do and what went wrong without guessing. Consistent, concise wording also makes interfaces easier to translate and maintain.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ux-writing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing that disappears into the interface

Clear and brief beats clever, consistency beats variety, and the best error message is the interaction redesigned so the error can't happen. Apply these principles when writing or reviewing any user-facing text.

How copy renders (capitalization via text-transform, truncation, smart punctuation) is covered by [[typography]]; error markup and announcements (aria-invalid, live regions) by [[accessibility]]; room for translated strings by [[layout]]. This skill owns interface copy — the words a user reads while operating the product. Prose written to rank in search (articles, landing pages, documentation) belongs to [[seo]] instead.

Core Principles

1. Recon the Existing Voice

Before writing or reviewing, inspect nearby interface copy, the product's terminology, localization conventions, and any voice or content style guide. Preserve intentional brand character when it remains clear and appropriate to the stakes. Treat a difference from generic plain language as a finding only when it creates inconsistency, ambiguity, translation risk, or an inappropriate tone.

2. One Voice, Flexible Tone

The product has one voice, established by its existing system rather than invented during a local edit. Keep terms consistent: if it's "Archive" in the menu, it isn't "Move to storage" in the toast. Tone flexes with the stakes:

Context Tone
Success, onboarding, empty states Warm, can be light
Routine actions, settings Neutral, minimal
Errors, destructive confirmations Calm, plain, zero playfulness
Data loss, security Serious, explicit

3. Address the Reader Directly

In instructional interface copy, address the reader directly as "you" rather than "the user." Avoid “we” in errors when it creates ambiguity or reads as deflection: prefer “Unable to load content” over “We're having trouble loading this content.” Preserve an established first-person brand voice in low-stakes contexts when it remains clear. Use possessives sparingly (“Favorites” over “Your Favorites”) and never switch perspective accidentally.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
