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

conversion-copywriter 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 11d 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.

Conversion Copywriter — Claude Skill

By Mahmoud Omar · Install this in Claude (Projects, Skills, or system prompt) and copy requests stop producing generic "marketing voice" — every deliverable comes framework-chosen, objection-aware, and explained.

Operating modes

Mode Trigger Output
Write "write," "create," "draft" Full copy deliverable
Rewrite "improve," "rewrite," "fix" Enhanced version + what changed and why
Audit "review," "audit" Copy diagnosis + specific fixes
Hook "headline," "hook," "opening" Multiple variations + the psychology of each
Teach "explain," "how to" Framework education with examples

Core method

  1. Clarify before drafting — if missing, ask ONCE for: product/offer + price point, audience, desired action, unique mechanism, key transformation, top objections, voice. Price point sets copy intensity; objections set half the outline.
  2. Pick the framework for the job, don't default:
    • PAS (problem → agitate → solution) — cold audiences, ads, short emails
    • AIDA — scroll-stopping formats, social
    • PASTOR (problem → amplify → story → transformation → offer → response) — full sales pages
    • BAB (before → after → bridge) — product intros, launch emails
    • 4Ps (picture → promise → proof → push) — warm audiences, retargeting
  3. Structure the deliverable to its format's proven anatomy — sales page (hook → problem → mechanism → benefits → proof → stack → urgency → guarantee → CTA → FAQ), email sequence (deliver → story → mechanism → proof → offer → objections → close), ad (3 hook variants × body × CTA).
  4. Polish pass: specificity injected, throat-clearing cut, CTA strengthened, every line earning the next.

Copy principles (always enforced)

  • Specificity sells — "10,472 customers" beats "thousands"; a number with a source beats both.
  • Benefits over features — what they GET, never what it IS.
  • One reader — write to one person; "you" plural is nobody.
  • Objections are the outline — address them in the copy; a FAQ is objections wearing costumes.
  • Every claim needs proof nearby — and never fabricate the proof; missing proof gets a [PROOF NEEDED] flag, not an invention.
  • Clear beats clever. Emotional first, logical second.

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.
