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-optimizer 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 1mo 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.

SEO Optimizer

Overview

Optimize websites for search engine visibility through technical SEO, on-page optimization, structured data implementation, and Core Web Vitals performance tuning. This skill covers crawlability, indexability, meta tag strategy, Schema.org markup, sitemap generation, canonical URL management, internationalization (hreflang), and performance optimization for Google's ranking signals.

Apply this skill whenever a site needs better organic search performance, whether for a single page audit or a full-site overhaul.

Multi-Phase Process

Phase 1: Technical Audit

  1. Crawl the site (Screaming Frog, Sitebulb, or custom script)
  2. Check robots.txt and XML sitemap validity
  3. Identify crawl errors, redirect chains, and broken links
  4. Verify canonical URLs and duplicate content handling
  5. Assess mobile-friendliness and responsive design
  6. Check HTTPS implementation and mixed content
  7. Evaluate page load performance (Core Web Vitals)

STOP — Do NOT proceed to Phase 2 until audit findings are documented and prioritized.

Phase 2: On-Page Optimization

  1. Audit title tags (unique, 50-60 chars, keyword placement)
  2. Review meta descriptions (unique, 150-160 chars, compelling CTAs)
  3. Analyze heading hierarchy (single H1, logical H2-H6 structure)
  4. Optimize image alt text and file names
  5. Review internal linking structure and anchor text
  6. Check URL structure (short, descriptive, hyphenated)
  7. Validate Open Graph and Twitter Card tags

STOP — Do NOT proceed to Phase 3 until on-page changes are implemented and verified.

Phase 3: Structured Data Implementation

  1. Identify applicable Schema.org types for content
  2. Implement JSON-LD structured data
  3. Validate with Google Rich Results Test
  4. Test for rich snippet eligibility
  5. Monitor Search Console for structured data errors

STOP — Do NOT proceed to Phase 4 until structured data passes validation.

Phase 4: Monitoring and Iteration

  1. Set up Google Search Console monitoring
  2. Track Core Web Vitals over time
  3. Monitor indexation status and coverage
  4. Review search performance (clicks, impressions, CTR, position)
  5. Set up alerts for crawl errors and ranking drops

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.
