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.

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 | $0.00159 | $0.01728 |
| Opus 5 | $0.00079 | $0.00864 |
| Sonnet 5 | $0.00032 | $0.00346 |
| Haiku 4.5 | $0.00016 | $0.00173 |
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 5d 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.
This is a copy
89% identical to copywriting — 20 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.
How it starts
The opening of the file, as written. The whole thing — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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-context.md exists (or .claude/product-marketing-context.md 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.
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"
Customer Language Over Company Language
Use words your customers use. Mirror voice-of-customer from reviews, interviews, support tickets.
One Idea Per Section
Each section should advance one argument. Build a logical flow down the page.
Writing Style Rules
Core Principles
- Simple over complex — "Use" not "utilize," "help" not "facilitate"
- Specific over vague — Avoid "streamline," "optimize," "innovative"
- Active over passive — "We generate reports" not "Reports are generated"
- Confident over qualified — Remove "almost," "very," "really"
- Show over tell — Describe the outcome instead of using adverbs
- Honest over sensational — Fabricated statistics or testimonials erode trust and create legal liability
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
