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

market-seo 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 10d 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

SEO Content Audit

Skill Purpose

Perform a comprehensive SEO audit of a webpage or website, covering on-page SEO, content quality (E-E-A-T), keyword analysis, technical SEO, and content strategy. This skill combines automated analysis via scripts/analyze_page.py with expert-level manual review to produce an actionable SEO audit document.

When to Use

  • User provides a URL and asks for SEO analysis, audit, or recommendations
  • User wants to improve organic search rankings and traffic
  • User asks about on-page SEO, meta tags, content quality, or technical SEO
  • User wants a content gap analysis or content strategy recommendations
  • Triggered by /market seo <url> or /market seo

How to Execute

Step 1: Run Automated Analysis

Use the Python analysis script to gather baseline data:

python3 scripts/analyze_page.py <url>

This script extracts:

  • Title tag and meta description
  • Open Graph tags
  • Heading hierarchy (H1-H6)
  • Links (internal and external)
  • Images and alt text status
  • Forms and CTAs
  • Schema/structured data
  • Social links
  • Tracking scripts
  • Viewport meta tag (mobile-friendliness indicator)
  • Canonical tag
  • Robots meta directives

Capture the JSON output and use it as the foundation for the manual analysis.

Step 2: On-Page SEO Checklist

Evaluate each element and score it as Pass, Needs Work, or Fail.

Title Tag
Criteria Best Practice Check
Exists Every page must have a unique title tag Pass/Fail
Length 50-60 characters (displays fully in SERPs) Pass/Needs Work/Fail
Primary keyword Contains the primary target keyword Pass/Needs Work/Fail
Keyword position Primary keyword appears near the beginning Pass/Needs Work/Fail
Brand name Includes brand name (typically at the end, separated by pipe or dash) Pass/Needs Work/Fail
Uniqueness Different from other pages on the site Pass/Fail
Compelling Would a searcher want to click this? Pass/Needs Work/Fail

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.
