In plain words

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

marketing 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.

Marketing Domain Knowledge

Key Metrics & Formulas

When calculating marketing metrics, use these standard definitions:

  • CAC (Customer Acquisition Cost): Total sales & marketing spend / Number of new customers acquired
  • LTV (Lifetime Value): Average revenue per customer × Average customer lifespan (or ARPU / churn rate for subscription businesses)
  • LTV:CAC Ratio: LTV / CAC (healthy = 3:1 or higher)
  • ROAS (Return on Ad Spend): Revenue from ads / Ad spend (break-even = 1.0)
  • CPC (Cost Per Click): Ad spend / Number of clicks
  • CPM (Cost Per Mille): (Ad spend / Impressions) × 1000
  • CTR (Click-Through Rate): Clicks / Impressions × 100
  • Conversion Rate: Conversions / Total visitors (or clicks) × 100
  • MQL → SQL Conversion: SQLs / MQLs × 100
  • Churn Rate: Customers lost in period / Customers at start of period × 100
  • NRR (Net Revenue Retention): (Starting MRR + expansion − contraction − churn) / Starting MRR × 100
  • Payback Period: CAC / (ARPU × Gross margin)

SEO Audits

When performing SEO audits, check for:

Technical SEO

  • Title tags (present, unique, 50-60 chars)
  • Meta descriptions (present, unique, 150-160 chars)
  • H1 tags (exactly one per page)
  • Image alt text
  • Canonical tags
  • robots.txt and sitemap.xml
  • Page speed / Core Web Vitals
  • Mobile responsiveness
  • HTTPS
  • Broken links (internal and external)
  • Structured data / schema markup

On-Page SEO

  • Keyword placement (title, H1, first 100 words, URL)
  • Internal linking structure
  • Content length and depth relative to competitors
  • URL structure (short, descriptive, hyphenated)

Content Quality Signals

  • Originality
  • E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness)
  • Freshness / last updated date
  • Multimedia (images, videos, infographics)

Email Marketing Best Practices

When generating email content:

  • Subject lines: 6-10 words, frontload the value prop, avoid spam triggers (FREE, !!!, ALL CAPS)
  • Preview text: Complement the subject line (don't repeat it), 40-130 chars
  • Body: One clear CTA per email, scannable with short paragraphs, personalization tokens where appropriate
  • Plain text version should always accompany HTML
  • Unsubscribe link is legally required (CAN-SPAM, GDPR)

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.
