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

microcopy-ux 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 2mo 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.

UX Microcopy

When to Activate

Use this skill when writing or reviewing interface text: button labels, form fields, error messages, success states, empty states, loading states, tooltips, onboarding flows, confirmation dialogs, notification copy, settings descriptions, or any text that helps users navigate and complete tasks within a product.

First Questions

  1. What is the product and who are the users? (technical vs. non-technical, B2B vs. B2C)
  2. What is the brand voice? (formal, friendly, playful, minimal, technical)
  3. What action or state is the copy supporting? (form completion, error recovery, onboarding, feature discovery)
  4. What platform? (web app, mobile app, desktop, email notification)
  5. What's the user's emotional state at this moment? (frustrated, excited, confused, anxious)

Core Principles of UX Microcopy

1. Clarity Over Cleverness

The user is trying to complete a task, not admire your writing. Every word should reduce friction.

  • Bad: "Oopsie-daisy! Something went sideways."
  • Good: "We couldn't save your changes. Please try again."

2. Guide, Don't Blame

When things go wrong, help the user fix the problem. Never imply it's their fault.

  • Bad: "You entered an invalid email address."
  • Good: "Please enter a valid email address (e.g., [email protected])."

3. Set Expectations

Tell users what will happen before, during, and after their action.

  • Before: "This will take about 2 minutes"
  • During: "Importing your contacts (43 of 128)..."
  • After: "Your contacts have been imported. You can now create your first campaign."

4. Match the Emotional Moment

The tone should match how the user feels at that point in the experience.

  • Payment failed: empathetic and helpful, not casual
  • First success: celebratory and encouraging
  • Routine task: minimal and efficient

5. Be Specific

Vague copy creates anxiety. Specific copy builds confidence.

  • Vague: "An error occurred."
  • Specific: "We couldn't process your payment. Your card was declined. Please try a different card or contact your bank."

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.
