ui-copy

ui-copy is a skill for Claude Code, Codex from superplanehq/superplane. It costs 72 tokens per session (1,419 once invoked), scanned A, original, Apache-2.0.

A guide for writing clear words used in software interfaces, such as buttons, labels, instructions, errors, and confirmation messages.

In plain words
What is it for?
Writing or reviewing interface text, including forms, empty states, onboarding, notifications, dialogs, links, and other user-facing product copy.
Why use it?
It helps users understand what they can do, what happened, and what will happen next without relying on vague or decorative wording.

About the project

SuperPlane is an open-source automation system that turns selected software backlog issues into pull requests by coordinating coding agents, source control, testing, review, and approvals. Engineering teams use it to automate routine development work while keeping ambiguous decisions for humans, and the catalogue add-ons support its workflows.

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

ui-copy 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 5d 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.

UI Copy

Write interface copy as part of the design, not as decoration after the layout is done. The product is speaking to someone who is trying to complete a task.

Adapted from Operately's ui-copy skill for SuperPlane product vocabulary.

Language: Write all user-facing strings in ASD-STE100 Simplified Technical English style. Follow simplified-technical-english together with this skill. If UX tone and STE conflict, choose the clearer STE wording.

Workflow

  1. Identify the user's current goal, screen state, and likely concern.
  2. Find nearby existing copy and match the product vocabulary, casing, tense, and tone.
  3. Draft the clearest STE version first. Prefer plain, specific, task-oriented language over personality.
  4. Tighten the copy until every word has a job (≤20 words for instructions, ≤25 for descriptions).
  5. Check that buttons, links, errors, and helper text set accurate expectations.
  6. If changing existing copy, scan adjacent screens or components for terms that should stay consistent.

Principles

  • Treat words as UI. Real copy belongs in early designs, prototypes, and implementation; do not rely on placeholder text when the wording affects comprehension, trust, or layout.
  • Clarity beats brevity and personality. Short is good only when it remains specific. Do not use cute, clever, or branded wording when it can hide the action.
  • Write for the user in this moment. Ask what they are trying to do, what they need to know now, what can wait, and whether they need reassurance.
  • Be honest and concrete. Avoid marketing adjectives, hype, vague promises, and copy that tells users how to feel.
  • Use STE plain language. Avoid jargon, unexplained acronyms, idioms, contractions, internal names, and technical error codes unless the user can act on them.
  • Prefer active voice, imperative or simple present, and specific verbs: Create, Save, Archive, Invite, Download, Connect.
  • Keep copy scannable. Use short sentences, front-load important words, and reveal advanced detail only when needed.
  • Keep vocabulary consistent. Do not alternate between terms like canvas, workflow, and pipeline unless the product treats them as different concepts.
  • Match the platform and interaction. Use tap for touch surfaces and click only where pointer interaction is the assumption.
  • Do not use humor in UI copy. Never use humor in high-friction, high-risk, error, payment, privacy, or destructive flows.

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.
