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 | $0.00037 | $0.01198 |
| Opus 5 | $0.00018 | $0.00599 |
| Sonnet 5 | $0.00007 | $0.00240 |
| Haiku 4.5 | $0.00004 | $0.00120 |
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 4d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copywriting Skill
Write compelling, conversion-focused marketing copy for web pages. Sourced from coreyhaines31/marketingskills.
Before Writing: Gather Context
Before writing any copy, establish:
- Page type — homepage, landing page, pricing page, feature page
- Primary visitor action — the single most important thing visitors should do
- Target audience — who they are, what they care about, their pain points
- Product differentiation — what makes this different from alternatives
- Desired outcomes — what the customer achieves by using the product
- Traffic source — where visitors come from and what they already know
- Voice and tone — brand personality and communication style
Core Writing Principles
Clarity Over Cleverness
Write so anyone can understand on first read. Avoid jargon, buzzwords, and marketing fluff. If a sentence requires re-reading, rewrite it.
Benefits Over Features
Features describe what a product does. Benefits describe what the customer achieves. Lead with benefits.
- Bad: "AI-powered analytics dashboard"
- Good: "Cut reporting from 4 hours to 15 minutes"
Specific Over Vague
Replace vague claims with concrete outcomes and numbers.
- Bad: "Streamline your workflow"
- Good: "Eliminate 12 manual steps from your onboarding process"
Active Voice
Write in active voice. The subject performs the action.
- Bad: "Reports are generated automatically"
- Good: "Generate reports automatically"
Mirror Customer Language
Use the exact words your customers use to describe their problems and goals. Pull from support tickets, reviews, interviews, and social posts.
Page Structure
Above the Fold
Every page needs three elements visible without scrolling:
- Headline — the single most compelling promise or outcome
- Subheadline — supporting detail that adds specificity or credibility
- CTA — a clear, action-oriented button
Core Page Sections
Structure the body using these sections (adapt order to page type):
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 ByeongminLee/nextjs-claude-code (3 stars, last pushed 5mo ago), licensed MIT. It adds 37 tokens to every session and 1,198 once invoked, about $0.0002 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 2026-08-31.
Other skills, from other repositories
stitch-ideate
Conversational design ideation agent that researches trends, explores visual directions, and refines ideas through adaptive questioning — then produces a rich PRD document and auto-generates Stitch screens. Your design buddy that thinks deeply before designing.
stitch-design-system
Extracts a Stitch design and generates production code artifacts — CSS custom properties with dark mode tokens, a Tailwind v4 @theme block, and a semantic design system document. Run this before framework conversion skills.
stitch-orchestrator
Master entry point for all Stitch design workflows. Routes from user request → design spec → prompt assembly → screen generation → iteration (edit, variants, design systems) → design system extraction → framework conversion (Next.js, Svelte, HTML, React Native, or SwiftUI) → optional quality pass.
stitch-react-native-components
Converts a Stitch mobile screen, a local HTML file, or a URL into React Native / Expo components — TypeScript, StyleSheet, Expo Router, dark mode via useColorScheme, and proper touch targets. Cross-platform iOS and Android. Only the Stitch route needs an API key.
stitch-swiftui-components
Converts a Stitch mobile screen, a local HTML file, or a URL into SwiftUI views for native iOS apps — VStack/HStack/ZStack layout mapping, Color asset tokens with dark mode, NavigationStack/TabView routing, and Xcode project structure. Only the Stitch route needs an API key.
stitch-a11y
Audits Stitch-generated components for WCAG 2.1 AA accessibility issues and applies fixes — semantic HTML, ARIA attributes, keyboard navigation, focus management, and screen reader support.
