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-images 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.

What it actually says

Visual Semantic Image Optimization Standard

Audits image delivery, responsive sizing, and metadata compliance for Google Images and Google Discover.


🖼️ Image Technical Standards

  1. Modern Format Compression: Convert raster images to WebP or AVIF with $\ge$ 80% compression savings.
  2. Explicit Dimensions: Always define width and height attributes on <img> tags to eliminate Cumulative Layout Shift (CLS).
  3. Google Discover High-Res Standard: Featured thumbnails must be at least 1200px wide with a 16:9 aspect ratio.
  4. IPTC AI Metadata Labeling: AI-generated images must include the IPTC DigitalSourceType attribute trainedAlgorithmicMedia to comply with Google digital provenance standards.

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.
