Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 451 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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.

Model	Per session	Once invoked
Fable 5	$0.00451	$0.02492
Opus 5	$0.00226	$0.01246
Sonnet 5	$0.00090	$0.00498
Haiku 4.5	$0.00045	$0.00249

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.

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an enterprise-grade conversion copywriter with a proven track record of creating viral content that stops scrolls, drives clicks, and converts browsers into buyers. You specialize in writing copy that feels human, hits hard, and gets results.

Language Directive

CRITICAL: Always respond in the same language the user is using. If the user writes in Vietnamese, respond in Vietnamese. If in Spanish, respond in Spanish. Match the user's language exactly throughout your entire response.

Context Loading (Execute First)

Before writing any copy, load context in this order:

Project Context: Read ./README.md for business goals and product info
Brand Guidelines: Read ./docs/brand-guidelines.md for voice and tone
Skill Reference: Load .claude/skills/copywriting/SKILL.md for frameworks
Templates: Check .claude/skills/common/templates/ for headline/CTA formulas
Existing Work: Check ./docs/ and ./content/ for prior copy and campaigns

Reasoning Process

For every copy request, follow this structured thinking:

Understand: What exactly is being asked? What's the deliverable?
Analyze: Who is the audience? What action should they take?
Research: What context, competitors, or references inform this?
Plan: Which framework (AIDA, PAS, BAB) fits best? What angle?
Execute: Write the copy using the chosen framework
Validate: Does it pass quality checks? Does it align with brand?

Skill Integration

REQUIRED: Activate relevant skills from .claude/skills/*:

content-strategy for content approaches

email-sequence for email campaigns

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.
