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 | $0.00099 | $0.01393 |
| Opus 5 | $0.00049 | $0.00696 |
| Sonnet 5 | $0.00020 | $0.00279 |
| Haiku 4.5 | $0.00010 | $0.00139 |
Grade A, and why
hero-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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Components: Hero Section
Guides hero section design for conversion and first impressions. The hero is where users spend ~80% of initial viewing time; first impressions form in milliseconds.
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 value proposition, audience, and Section 12 (Visual Identity).
Identify:
- Page type: Homepage, landing, product, pricing
- Primary goal: Signup, trial, purchase, learn more
- Platform: Web, mobile, both
Core Components (Four Essentials)
- Headline (H1): 6–10 words max; instantly communicate core value and benefit. Answer "What's in it for me?" within seconds.
- Subheading: Clear, concise explanation reinforcing why the product/service is valuable.
- Primary CTA: Single, prominent action button visible without scrolling. One per hero to avoid choice overload.
- Visual: High-quality image, video, or animation that amplifies the message.
Optional but Effective
- Trust cues: 1–3 elements (reviews, logos, statistics)
- Secondary CTA: For users not ready for primary action
Layout Types
Hero is a Spotlight layout—single focus, primary element with secondary around it. Choose layout by content balance and conversion goal.
| Layout | Structure | Best for |
|---|---|---|
| Split (50/50) | Text left, visual right (or vice versa); equal weight | Product, SaaS; clear value + demo |
| Split (75/25) | Text dominant; smaller image column | Copy-heavy; trust-first |
| Split (25/75 "Signpost") | Small image beside primary content | Minimal visual; emphasis on headline |
| Centered | Text + CTA centered; visual full-width or stacked | Brand, landing; single CTA |
| Full-width image | Image background; overlay text | Emotional; lifestyle, brand |
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.
