Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00081 | $0.02079 |
| Opus 5 | $0.00041 | $0.01040 |
| Sonnet 5 | $0.00016 | $0.00416 |
| Haiku 4.5 | $0.00008 | $0.00208 |
Grade A, and why
technical-seo-audit scanned grade A with 1 finding 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.

Technical SEO Audit
Deep technical SEO analysis: crawlability, indexation, Core Web Vitals, site architecture, and performance.
Install

How this differs from seo-content-writer: The seo-content-writer skill focuses on content optimization — keywords, readability, meta tags, heading structure. This skill audits the technical foundation — can search engines crawl, render, and index your site correctly?
Audit Framework
Phase 1: Crawlability & Indexation
robots.txt Analysis
- Verify file exists at
/robots.txt - Check for unintentional blocks (
Disallow: /on production) - Validate sitemap reference
- Review AI crawler directives (GPTBot, ClaudeBot, PerplexityBot)
XML Sitemap Audit
- Validate sitemap format (XML schema compliance)
- Check for 404, 301, or 5xx URLs in sitemap
- Verify lastmod dates are accurate (not all the same date)
- Confirm sitemap is referenced in robots.txt
- Check sitemap size (under 50MB / 50,000 URLs per file)
- For large sites: verify sitemap index file structure
Indexation Health
- Compare indexed pages (site:domain.com) vs expected pages
- Identify index bloat (thin, duplicate, or low-value pages indexed)
- Check for noindex tags on important pages
- Review Google Search Console coverage report patterns
- Identify orphan pages (in sitemap but no internal links)
Crawl Budget Optimization
- Identify crawl traps (infinite pagination, calendar URLs, faceted navigation)
- Check crawl depth (critical pages should be within 3 clicks)
- Review log files for crawler behavior patterns
- Identify wasted crawl budget on low-value URLs
Phase 2: Site Architecture & Internal Linking
URL Structure
- Consistent URL patterns (lowercase, hyphens, no trailing slashes OR consistent trailing slashes)
- Logical hierarchy reflecting content taxonomy
- No URL parameters where clean URLs are possible
- Proper handling of pagination (rel=next/prev or load-more)
What ships with it
3 files 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.
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.
