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-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 13d 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.

Usage

/ux-copy $ARGUMENTS

What I Need From You

  • Context: What screen, flow, or feature?
  • User state: What is the user trying to do? How are they feeling?
  • Tone: Formal, friendly, playful, reassuring?
  • Constraints: Character limits, platform guidelines?

Principles

  1. Clear: Say exactly what you mean. No jargon, no ambiguity.
  2. Concise: Use the fewest words that convey the full meaning.
  3. Consistent: Same terms for the same things everywhere.
  4. Useful: Every word should help the user accomplish their goal.
  5. Human: Write like a helpful person, not a robot.

Copy Patterns

CTAs

  • Start with a verb: "Start free trial", "Save changes", "Download report"
  • Be specific: "Create account" not "Submit"
  • Match the outcome to the label

Error Messages

Structure: What happened + Why + How to fix

  • "Payment declined. Your card was declined by your bank. Try a different card or contact your bank."

Empty States

Structure: What this is + Why it's empty + How to start

  • "No projects yet. Create your first project to start collaborating with your team."

Confirmation Dialogs

  • Make the action clear: "Delete 3 files?" not "Are you sure?"
  • Describe consequences: "This can't be undone"
  • Label buttons with the action: "Delete files" / "Keep files" not "OK" / "Cancel"

Tooltips

  • Concise, helpful, never obvious

Loading States

  • Set expectations, reduce anxiety

Onboarding

  • Progressive disclosure, one concept at a time

Voice and Tone

Adapt tone to context:

  • Success: Celebratory but not over the top
  • Error: Empathetic and helpful
  • Warning: Clear and actionable
  • Neutral: Informative and concise

Output

## UX Copy: [Context]

### Recommended Copy
**[Element]**: [Copy]

### Alternatives
| Option | Copy | Tone | Best For |

| A | [Copy] | [Tone] | [When to use] |
| B | [Copy] | [Tone] | [When to use] |
| C | [Copy] | [Tone] | [When to use] |

### Rationale
[Why this copy works — user context, clarity, action-orientation]

### Localization Notes
[Anything translators should know — idioms to avoid, character expansion, cultural context]
