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

copywriting 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.

UI/UX Copywriting Guidelines

This skill focuses on writing effective microcopy for user interfaces, marketing assets, and onboarding flows. Good copy guides the user seamlessly while reflecting the brand's personality.

1. Tone of Voice

Our tone is Friendly, Professional, and Concise.

  • Friendly: Welcoming, helpful, and empathetic, especially when things go wrong.
  • Professional: Authoritative without being overly formal. We know what we are doing.
  • Concise: Respect the user's time. Say more with fewer words.

2. Writing Clear CTAs (Calls to Action)

CTAs should clearly indicate what will happen when the user clicks.

  • Use strong verbs: Start with an action word (e.g., Get, Create, Save, Subscribe).
  • Be specific: Avoid generic terms if a more descriptive term fits.
    • Bad: Submit, Click Here, OK
    • Good: Create Account, Send Message, Save Changes
  • Keep it short: Aim for 2-4 words.

3. Handling Error Messages

Error messages should never blame the user. They must explain what went wrong and how to fix it.

  • Be empathetic: Avoid aggressive words like "Failed," "Prohibited," or "Illegal."
  • Provide a solution: Tell the user what to do next.
  • Examples:
    • Bad: Invalid password. Try again.
    • Good: Your password needs to be at least 8 characters long.
    • Bad: System error 404.
    • Good: We couldn't find that page. Let's get you back to the home page.

4. Designing Empty States

Empty states are opportunities to educate and encourage action, not dead ends.

  • Explain the value: Tell the user what goes here and why they should care.
  • Provide an action: Always include a CTA to help them get started.
  • Example (Empty Inbox):
    • Headline: You're all caught up!
    • Body: When you receive new messages, they'll appear right here.
    • CTA: Browse Contacts

5. Onboarding Copy

Onboarding should highlight value, not just explain features.

  • Focus on benefits: Explain why a feature matters, not just how it works.
  • Keep it digestible: One concept per screen/tooltip.
  • Allow skipping: Respect users who prefer to explore independently.

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.
