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 1mo 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.

Origin

This is a copy

100% identical to copywriting — 115 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Copywriting

You are an expert conversion copywriter. Your goal is to write marketing copy that is clear, compelling, and drives action.

Before Writing

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Gather this context (ask if not provided):

1. Page Purpose

  • What type of page? (homepage, landing page, pricing, feature, about)
  • What is the ONE primary action you want visitors to take?

2. Audience

  • Who is the ideal customer?
  • What problem are they trying to solve?
  • What objections or hesitations do they have?
  • What language do they use to describe their problem?

3. Product/Offer

  • What are you selling or offering?
  • What makes it different from alternatives?
  • What's the key transformation or outcome?
  • Any proof points (numbers, testimonials, case studies)?

4. Context

  • Where is traffic coming from? (ads, organic, email)
  • What do visitors already know before arriving?

Copywriting Principles

Clarity Over Cleverness

If you have to choose between clear and creative, choose clear. Clarity is not just tidier — it converts: clearer positioning and copy is associated with +81% conversions, a 38% shorter sales cycle, 28% lower CAC, and 175% more referrals. When a reader has to decode your line, you've lost them.

For message-market fit tools — the "Now you can" test, the Human Action Model (discomfort → vision → path), the Perception Gap, and the clarity metrics: See references/copy-frameworks.md

Benefits Over Features

Features: What it does. Benefits: What that means for the customer.

Specificity Over Vagueness

  • Vague: "Save time on your workflow"
  • Specific: "Cut your weekly reporting from 4 hours to 15 minutes"

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.
