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

site-health 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 12d 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.

Technical Site Health Check

Analyze site structure, internal linking, performance metrics, accessibility, and content decay.

Instructions

  1. Resolve the domain. If $ARGUMENTS is provided, use it as the domain. If not, call list_websites and ask the user which site to analyze.

  2. Fetch site topology. Call get_site_topology with the domain. This returns orphan pages, link depth distribution, most linked pages, and average links per page.

  3. Fetch page speed for the homepage. Call get_pagespeed with:

    • domain: the target domain
    • url: the homepage URL (typically https://[domain]/)
  4. Optionally fetch speed for hub pages. If topology reveals pages with many incoming links, check their speed with get_pagespeed for 1-2 of the most linked pages.

  5. Fetch accessibility issues. Call list_accessibility_issues with:

    • domain: the target domain
    • page_size: 10
  6. Fetch content decay alerts. Call list_content_decay with:

    • domain: the target domain
    • is_active: "true"
    • page_size: 10
  7. Synthesize into a technical health report.

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.
