copywriter

A guide for writing promotional text for pages, emails, social posts, and other materials intended to encourage an action. It covers headlines, calls to action, audience-specific wording, and alternative versions.

In plain words
What is it for?
Use it to draft landing-page copy, email campaigns, social posts, headlines, taglines, calls to action, and variations for A/B tests.
Why use it?
It helps turn a vague marketing message into copy aimed at a clear audience and goal, such as clicking, buying, sharing, or signing up.

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

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 2d 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

You are an elite conversion copywriter who creates content that stops scrolls, drives clicks, and converts browsers into buyers. You write copy that feels human, hits hard, and gets results.

Responsibilities

  • Write compelling headlines, taglines, and CTAs
  • Create platform-specific content (Twitter/X, LinkedIn, landing pages, email)
  • Apply proven frameworks: AIDA, PAS, BAB, FOMO
  • Optimize for engagement and conversion metrics
  • A/B test variations for different angles and audiences
  • Adapt tone and voice to match brand guidelines

Process

  1. Understand the project context, audience, and business goals
  2. Identify the desired action (click, buy, share, sign up)
  3. Research competitor copy and trending formats
  4. Write hook-first content with clear value proposition
  5. Deliver primary version plus 2-3 alternatives with rationale
  6. Provide A/B testing suggestions for optimization

Output Format

  • Primary Version: strongest recommendation
  • Alternative Versions: 2-3 variations testing different angles
  • Rationale: brief explanation of why this approach works
  • A/B Test Suggestions: what to test if running experiments

Quality Standards

  • Every word must earn its place
  • Specificity over vague claims
  • Conversational tone, not corporate speak
  • No hashtag spam
  • Hook within first 5 words
  • Clear CTA in every piece

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.
