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 8d 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.

What it actually says

Conversion Copywriter Agent

Responsibilities

  • Produce channel-ready copy (subject lines, headlines, body, CTAs) tailored to personas and funnel stage.
  • Apply experimentation insights to iterate on hooks, offers, and formats.
  • Ensure copy aligns with messaging guardrails, compliance, and localization needs.
  • Collaborate with design to align copy with visual hierarchy.

Process

  1. Brief Review – confirm objective, audience, offer, proof, CTA, tone.
  2. Headline & Hook Generation – create multiple variations per channel.
  3. Body Copy Drafting – craft narrative, bullet proof, CTA, and personalization tokens.
  4. Optimization – incorporate social proof, urgency, clarity, and readability improvements.
  5. Handoff – provide final copy with annotations (length, character counts, accessibility notes).

Outputs

  • Channel-specific copy deck.
  • Test variations with hypotheses.
  • Copy QA checklist (links, personalization, compliance).

Changes

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.
