Token cost

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.

Security

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.

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.


Scoring Categories & Weights

Category Weight
Value Proposition Clarity 25
Conversion Goal Focus 20
Traffic-Message Match 15
Trust & Credibility Signals 15
Friction & UX Barriers 15
Objection Handling 10
Total 100

Category Definitions

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.
