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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check-output.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Copywriting

Overview

Copywriting is salesmanship in print. Every word either moves the reader toward action or gives them a reason to leave. This skill covers conversion copywriting: headlines that stop the scroll, body copy that builds desire, and CTAs that convert. Draws from the best practitioners in the field.

When to Use

  • "Write landing page copy"
  • "Create ad headlines"
  • "Write email marketing copy"
  • "Craft a tagline"
  • "Improve our messaging"
  • "Write social media captions"
  • "Rewrite this to convert better"

Authoritative Foundations

  • Joanna Wiebe (Copyhackers) — conversion copywriting. Start with the prospect's problem, not your product. "What's in it for me?" answered in the first 3 seconds.
  • Eugene Schwartz — 5 awareness levels: Unaware, Problem-Aware, Solution-Aware, Product-Aware, Most Aware. Match copy to awareness.
  • Robert Cialdini — 7 persuasion principles: reciprocity, commitment, social proof, authority, liking, scarcity, unity.
  • Neville Medhora (Kopywriting Kourse) — practical frameworks. AIDA, PAS, features-to-benefits transformation.

Step-by-Step Process

Phase 1: Intake

Who is the audience? What awareness level? What's the desired action? What's the primary objection? What's the proof?

Phase 2: Framework Selection

  • AIDA: Attention → Interest → Desire → Action (universal)
  • PAS: Problem → Agitation → Solution (pain-first)
  • BAB: Before → After → Bridge (transformation story)
  • 4Ps: Promise → Picture → Proof → Push (direct response)
  • Features-to-Benefits: "This does X" → "So you can Y"

Phase 3: Headline Writing

Headlines do 80% of the work. Rules: specific > clever, benefit > feature, under 15 words, no jargon. Test multiple variants. The best headline makes the reader think "tell me more."

Phase 4: Body Copy

Lead with the problem. Show you understand. Prove you can solve it. End with a single clear action. Write like you talk — read it aloud. If it sounds like marketing, rewrite it.
