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

seo-page 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.

Origin

This is a copy

92% identical to seo-page — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Single Page Analysis

What to Analyze

On-Page SEO

  • Title tag: 50-60 characters, includes primary keyword, unique
  • Meta description: 150-160 characters, compelling, includes keyword
  • H1: exactly one, matches page intent, includes keyword
  • H2-H6: logical hierarchy (no skipped levels), descriptive
  • URL: short, descriptive, hyphenated, no parameters
  • Internal links: sufficient, relevant anchor text, no orphan pages
  • External links: to authoritative sources, reasonable count

Content Quality

  • Word count vs page type minimums (see quality-gates.md)
  • Readability: Flesch Reading Ease score, grade level
  • Keyword density: natural (1-3%), semantic variations present
  • E-E-A-T signals: author bio, credentials, first-hand experience markers
  • Content freshness: publication date, last updated date

Technical Elements

  • Canonical tag: present, self-referencing or correct
  • Meta robots: index/follow unless intentionally blocked
  • Open Graph: og:title, og:description, og:image, og:url
  • Twitter Card: twitter:card, twitter:title, twitter:description
  • Hreflang: if multi-language, correct implementation

Schema Markup

  • Detect all types (JSON-LD preferred)
  • Validate required properties
  • Identify missing opportunities
  • NEVER recommend HowTo (deprecated) or FAQ (restricted to gov/health)

Images

  • Alt text: present, descriptive, includes keywords where natural
  • File size: flag >200KB (warning), >500KB (critical)
  • Format: recommend WebP/AVIF over JPEG/PNG
  • Dimensions: width/height set for CLS prevention
  • Lazy loading: report lazy_method per image (native | perfmatters | ewww | js-generic | none). Do not flag "not lazy-loaded" when JS lazy-loaders (Perfmatters, EWWW, lazysizes) are detected — they intentionally strip the native loading="lazy" attribute and use data-src placeholders

Core Web Vitals (reference only, not measurable from HTML alone)

  • Flag potential LCP issues (huge hero images, render-blocking resources)
  • Flag potential INP issues (heavy JS, no async/defer)
  • Flag potential CLS issues (missing image dimensions, injected content)

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
