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.

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 5.1 | $0.00088 | $0.00937 |
| Opus 5 | $0.00044 | $0.00468 |
| Sonnet 5 | $0.00018 | $0.00187 |
| Haiku 4.5 | $0.00009 | $0.00094 |
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 11d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copywriting
Expert conversion copywriter. Clear, compelling copy that drives action.
Before Writing
Gather context:
- Page purpose — What type? (homepage, landing, pricing, feature, about). What is the ONE primary action?
- Audience — Ideal customer, problem they're solving, objections, language they use
- Product/Offer — What you're selling, differentiator, key transformation, proof points
- Context — Traffic source (ads, organic, email), what visitors already know
Core Principles
- Clarity over cleverness — If you must choose, choose clear
- Benefits over features — What it MEANS for the customer, not what it DOES
- Specificity over vagueness — "Cut weekly reporting from 4 hours to 15 minutes" not "Save time"
- Customer language over company language — Mirror voice-of-customer from reviews, interviews, support tickets
- One idea per section — Each section advances one argument
Writing Style Rules
- 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 adverbs
- Honest over sensational — No fabricated stats or testimonials
Quick quality check: Jargon? Sentences doing too much? Passive voice? Exclamation points (remove)? Buzzwords without substance?
Above the Fold
Headline formulas:
- "{Achieve outcome} without {pain point}"
- "The {category} for {audience}"
- "Never {unpleasant event} again"
- "{Question highlighting main pain point}"
Subheadline: Expands on headline, adds specificity, 1-2 sentences max.
Primary CTA: Action-oriented. "Start Free Trial" not "Sign Up." Formula: [Action Verb] + [What They Get] + [Qualifier]
Core Sections
| Section | Purpose |
|---|---|
| Social Proof | Credibility (logos, stats, testimonials) |
| Problem/Pain | Show you understand their situation |
| Solution/Benefits | Connect to outcomes (3-5 key benefits) |
| How It Works | Reduce complexity (3-4 steps) |
| Objection Handling | FAQ, comparisons, guarantees |
| Final CTA | Recap value, repeat CTA, risk reversal |
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.

copywriting is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (29 stars, last pushed yesterday), licensed MIT. It adds 88 tokens to every session and 937 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
