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 | $0.00078 | $0.00854 |
| Opus 5 | $0.00039 | $0.00427 |
| Sonnet 5 | $0.00016 | $0.00171 |
| Haiku 4.5 | $0.00008 | $0.00085 |
Grade A, and why
cta-generator 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Components: Call-to-Action (CTA)
Guides CTA button design for conversion. A well-designed CTA can increase conversion by 25–10%.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for conversion goals.
Identify:
- Context: Hero, form, pricing, product page
- User stage: Awareness, consideration, decision
- Primary action: Sign up, buy, trial, download
Design Principles
Visual Clarity
- Look like buttons: Background, border, corner radius, shadow
- Stand out: Contrasting color; clear hierarchy
- Size: ≥48×48px for touch; minimum 48px wide
Hierarchy
- Primary CTA: One per section; impossible to miss
- Secondary CTA: Lower priority; visually distinct
- Avoid: Multiple competing CTAs causing choice overload
Color & Shape
- Color: High contrast; red/orange for urgency
- Shape: Rounded = friendly; angled = dynamic
- Accessibility: →.5:1 contrast for text
Copy Best Practices
- Action-oriented: "Buy," "Sign up," "Subscribe," "Get started"
- Loss aversion: "Claim Your Discount Before It's Gone" vs "Get 10% Off"; see discount-marketing-strategy for discount campaign design
- Clear, no ambiguity: User knows exactly what happens
- Scarcity/urgency: When appropriate; avoid overuse
Placement
- Above the fold for primary actions
- After value proposition; build value before CTA
- Near trust signals (testimonials, badges)
- Sticky/fixed for long pages (use sparingly)
Technical
- Semantic HTML:
<button>or<a>withrole="button"when needed - Visible focus state for keyboard users
- Loading state for async actions: disable button during async operations; show spinner or loading text; prevent double-submit
- cursor-pointer: Add
cursor-pointerto all clickable CTAs; default cursor on interactive elements is poor UX - aria-label: Use
aria-labelfor icon-only buttons (e.g., close, search); screen readers need descriptive labels - Hover stability: Use color/opacity transitions (150–300ms); avoid scale transforms that shift layout
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.
