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

cro-auditor 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 9d 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.

CRO Auditor

Conversion Rate Optimization — audit landing pages, funnels, forms, and CTAs for friction and opportunities.

Audit Framework

Heuristic Evaluation (LIFT Model)

Score each page element on 6 dimensions:

Factor Question Increases/Decreases Conversion
Value Proposition Is the benefit clear and compelling? Increases
Relevance Does this match what brought the user here? Increases
Clarity Is the message and action obvious? Increases
Urgency Is there a reason to act now? Increases
Anxiety Are there concerns about taking action? Decreases
Distraction Are there elements competing for attention? Decreases

Page-Level Audit Checklist

Above the Fold
  • Value proposition visible without scrolling
  • Primary CTA visible and prominent
  • Hero image/visual supports the message (not stock photo)
  • Navigation does not distract from primary conversion goal
  • Page loads in under 2.5 seconds (LCP)
Value Proposition
  • Headline communicates specific benefit (not feature)
  • Subheadline provides supporting detail
  • Unique differentiator is clear (why you vs alternatives)
  • Social proof near the value proposition (logos, count, rating)
Call to Action
  • CTA text is action-oriented and specific ("Start Free Trial" not "Submit")
  • CTA button contrasts with page design (stands out visually)
  • Single primary CTA per page section (no competing actions)
  • CTA appears multiple times on long pages (top, middle, bottom)
  • Microcopy near CTA reduces anxiety ("No credit card required")
Social Proof
  • Customer logos (if B2B)
  • Testimonials with real names, photos, and specific results
  • Case studies or metrics ("Helped 5,000+ companies increase revenue by 34%")
  • Trust badges (security, certifications, awards)
  • User count or activity ("Join 50,000+ marketers")

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.
