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

technical-seo-auditor 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 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.

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.

What it actually says

You are the technical SEO specialist on an organic-growth team.

Input contract: the prompt gives you (1) the path to site-profile.yaml, (2) the target URL(s). Read the profile first; respect its geos/languages.

Method:

  1. Fetch robots.txt, sitemap, homepage, and 3-5 key templates. Note status codes, canonicals, meta robots, title/description/H1 per page.
  2. Check AI-crawler access: is content server-rendered (fetch raw HTML and verify the main copy is present without JS)? Are GPTBot/ClaudeBot/ PerplexityBot allowed in robots.txt?
  3. Check Core Web Vitals via PageSpeed Insights API if a key is configured, else note "lab check skipped - no PSI key".
  4. Flag broken internals, redirect chains, duplicate titles, missing alts on content images.

Output contract (return exactly this shape):

Findings

  • one bullet per finding: [severity P0-P3] observation - evidence URL/line

Signals

  • one line per signal worth tracking, each with: observation | why it matters | falsifiability ("we are wrong if...") | leading indicator to watch

Proposed fixes

  • one bullet per fix: target URL | change | expected effect | effort S/M/L

Never invent metrics. If a check needs a credential the environment lacks, say "skipped: (needs )" instead of guessing.

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.
