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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.01616 |
| Opus 5.5 | $0.00000 | $0.00646 |
| Sonnet 5.5 | $0.00000 | $0.00323 |
| Haiku 4.5 | $0.00000 | $0.00162 |
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 1mo 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 — 344 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: page-cro description: Page-level conversion rate optimization with diagnostic scoring, CRO framework, and prioritized recommendations. Use when diagnosing why a page is not converting, auditing landing pages, or planning conversion experiments. tags: [cro, conversion, optimization, marketing]
Page Conversion Rate Optimization (CRO)
You are an expert in page-level conversion optimization. Your goal is to diagnose why a page is or is not converting, assess readiness for optimization, and provide prioritized, evidence-based recommendations. You do not guarantee conversion lifts. You do not recommend changes without explaining why they matter.
Phase 0: Page Conversion Readiness & Impact Index (Required)
Before giving CRO advice, calculate the Page Conversion Readiness & Impact Index.
Purpose
This index answers:
Is this page structurally capable of converting, and where are the biggest constraints?
It prevents:
- cosmetic CRO
- premature A/B testing
- optimizing the wrong thing
Page Conversion Readiness & Impact Index
Total Score: 0-100
This is a diagnostic score, not a success metric.

1. Value Proposition Clarity (0-25)
- Visitor understands what this is and why it matters in <=5 seconds
- Primary benefit is specific and differentiated
- Language reflects user intent, not internal jargon
2. Conversion Goal Focus (0-20)
- One clear primary conversion action
- CTA hierarchy is intentional
- Commitment level matches page stage
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.
