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

accessibility-audit 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.

Accessibility Audit — Phase 19 (SEO-Focused)

Executive Summary

Accessibility and SEO are converging in 2025. Semantic HTML — the foundation of accessibility compliance — is also Googlebot's preferred signal architecture. Lighthouse accessibility score directly correlates with Core Web Vitals performance, particularly INP (Interaction to Next Paint, replaced FID March 2024) and CLS. Google's Quality Rater Guidelines (2024 update) explicitly flag accessibility as an E-E-A-T trust indicator. Legal exposure from accessibility failures is escalating: ADA Title III lawsuits reached 4,605 in 2023 (Seyfarth Shaw), and negative SERP results from lawsuit coverage directly harm brand SERP. AI search systems (Google AIO, ChatGPT, Perplexity) preferentially extract content from semantically correct, accessible HTML structures — inaccessible pages are de facto AI-invisible.

2025 accessibility benchmarks:

  • WCAG 2.2 AA = current legal standard (US ADA, EU EAA effective June 2025, AU DDA)
  • Lighthouse score ≥90 = target; <70 = flag as structural risk to E-E-A-T
  • 96.3% of the top 1 million homepages have WCAG failures (WebAIM Million Report 2024)
  • Semantic HTML headings = 41% higher featured snippet acquisition (SEMrush 2024)
  • INP <200ms (Good) = primary CWV threshold since March 2024 — poor accessibility patterns (no skip links, large unoptimized tap targets) are INP contributors
  • Touch target minimum: 24×24px (WCAG 2.2 new criterion 2.5.8, Oct 2023)

Why Accessibility Matters for SEO (2025)

  1. INP & CLS — poor accessibility (no skip links, large tap targets missing) causes bad Core Web Vital scores; INP target <200ms
  2. Crawlability — screen reader-friendly semantic HTML = Googlebot-friendly; JS-only content risks non-rendering
  3. E-E-A-T — inclusive design signals quality and professionalism — Quality Rater Guidelines (2024) specifically flag accessibility as a trust indicator
  4. Legal risk — ADA Title III lawsuits hit 4,605 cases in 2023 (Seyfarth Shaw data); lawsuits = negative SERP results (reputation risk)
  5. Featured snippets — well-structured semantic HTML wins 2–3× more featured snippets vs. unsemantic markup
  6. WCAG 2.2 — new criteria (October 2023): Focus Not Obscured, Dragging Movements, Target Size (minimum 24×24px)

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.
