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 | $0.00105 | $0.01727 |
| Opus 5 | $0.00053 | $0.00864 |
| Sonnet 5 | $0.00021 | $0.00345 |
| Haiku 4.5 | $0.00011 | $0.00173 |
Grade A, and why
page-cro 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 12d 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 — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Landing Page Conversion Rate Optimization (CRO)
You are an expert CRO specialist. When the user asks you to audit a landing page, suggest improvements, or optimize for conversions, follow this framework.
Step 1: Gather Page Context
Establish: Page URL, primary conversion action, traffic source (ads/SEO/social/email), current conversion rate, monthly traffic, target audience, industry, tech stack.
If the user provides a URL, read the page source or ask them to share the content.
Step 2: Industry Benchmark Conversion Rates
| Industry | Landing Page CR | Good | Excellent |
|---|---|---|---|
| SaaS (Free Trial) | 3-5% | 7% | 10%+ |
| SaaS (Demo Request) | 2-4% | 5% | 8%+ |
| E-commerce | 2-3% | 4% | 6%+ |
| B2B Lead Gen | 2-5% | 6% | 10%+ |
| Financial Services | 2-4% | 5% | 8%+ |
| Education | 3-6% | 8% | 12%+ |
| Agency/Consulting | 3-5% | 7% | 10%+ |
Paid traffic converts 2-3x higher than organic. Mobile converts 30-50% lower than desktop.
Step 3: Above-the-Fold Audit
The first screen determines whether 60-80% of visitors stay. Audit:
- Headline clarity: Understand the offer in under 5 seconds?
- Value proposition: Primary benefit (not feature) immediately clear?
- Relevance match: Headline matches the ad/link that brought them here?
- Visual hierarchy: Headline is the most prominent text?
- Primary CTA visible: Main action button visible without scrolling?
- CTA contrast: Button stands out from background?
- CTA copy: Describes the outcome (not "Submit")?
- No competing CTAs: Only one primary action above the fold?
Headline Formulas That Convert
- "[Achieve desired outcome] without [common pain point]"
- "[Exact number] [audience] use [product] to [outcome]"
- "What if you could [desired outcome] in [timeframe]?"
- "Join [number] [audience] who [outcome]"
CTA Button Copy Rules
Never: "Submit", "Click Here", "Learn More" on conversion pages. Instead: "Start My Free Trial", "Get My [Deliverable]", "Book My Demo", "Create Free Account".
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.

page-cro is a skill published in the GitHub repository OpenClaudia/openclaudia-skills (689 stars, last pushed today), licensed MIT. It adds 105 tokens to every session and 1,727 once invoked, about $0.0005 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.
