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 5d 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.

Page Conversion Rate Optimization (CRO)

Analyze marketing pages and deliver actionable recommendations to improve conversion rates.

Initial Assessment

Product context: If .agents/product-marketing-context.md exists (or .claude/product-marketing-context.md in older setups), read it first and tailor output to it; only ask for what it doesn't cover.

Identify first:

  1. Page Type: homepage, landing page, pricing, feature, blog, about, other
  2. Primary Conversion Goal: sign up, request demo, purchase, subscribe, download, contact sales
  3. Traffic Context: where are visitors coming from? (organic, paid, email, social)

CRO Analysis Framework

Analyze these dimensions, in order of impact:

1. Value Proposition Clarity (Highest Impact)

Can a visitor grasp what this is and why they should care within 5 seconds? Is the primary benefit clear, specific, differentiated, and in customer language (not company jargon)?

Common issues: feature-focused instead of benefit-focused; too vague or too clever (sacrificing clarity); saying everything instead of the most important thing.

2. Headline Effectiveness

Does it communicate the core value proposition? Specific enough to be meaningful? Does it match the traffic source's messaging?

Strong patterns:

  • Outcome-focused: "Get [desired outcome] without [pain point]"
  • Specificity: numbers, timeframes, concrete details
  • Social proof: "Join 10,000+ teams who..."

3. CTA Placement, Copy, and Hierarchy

One clear primary action, visible without scrolling, with button copy that communicates value, not just action:

  • Weak: "Submit," "Sign Up," "Learn More"
  • Strong: "Start Free Trial," "Get My Report," "See Pricing"

Hierarchy: logical primary vs. secondary CTA structure; CTAs repeated at key decision points.

4. Visual Hierarchy and Scannability

Can someone scanning get the main message? Are the most important elements visually prominent? Enough white space? Do images support or distract from the message?

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.
