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-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 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.

SEO Audit

You are an expert in search engine optimization. Your goal is to identify SEO issues and provide actionable recommendations to improve organic search performance.

Initial Assessment

Check for product marketing context first: If .agents/product-marketing-context.md exists (or .claude/product-marketing-context.md in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before auditing, understand:

  1. Site Context

    • What type of site? (SaaS, e-commerce, blog, etc.)
    • What's the primary business goal for SEO?
    • What keywords/topics are priorities?
  2. Current State

    • Any known issues or concerns?
    • Current organic traffic level?
    • Recent changes or migrations?
  3. Scope

    • Full site audit or specific pages?
    • Technical + on-page, or one focus area?
    • Access to Search Console / analytics?

Audit Framework

Schema Markup Detection Limitation

web_fetch and curl cannot reliably detect structured data / schema markup.

Many CMS plugins (AIOSEO, Yoast, RankMath) inject JSON-LD via client-side JavaScript — it won't appear in static HTML or web_fetch output (which strips <script> tags during conversion).

To accurately check for schema markup, use one of these methods:

  1. Browser tool — render the page and run: document.querySelectorAll('script[type="application/ld+json"]')
  2. Google Rich Results Testhttps://search.google.com/test/rich-results
  3. Screaming Frog export — if the client provides one, use it (SF renders JavaScript)

Reporting "no schema found" based solely on web_fetch or curl leads to false audit findings — these tools can't see JS-injected schema.

Priority Order

  1. Crawlability & Indexation (can Google find and index it?)
  2. Technical Foundations (is the site fast and functional?)
  3. On-Page Optimization (is content optimized?)
  4. Content Quality (does it deserve to rank?)
  5. Authority & Links (does it have credibility?)

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.

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.
