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

add-seo 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 6d 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

Add comprehensive SEO to a page using Next.js 15 Metadata API.

Generate:

  • Metadata object with title, description, keywords
  • Open Graph tags for social media sharing (title, description, image, type, url)
  • Twitter Card tags for Twitter sharing
  • Canonical URL configuration
  • Robots meta tags for indexing control
  • JSON-LD structured data (Schema.org) for rich snippets
  • Dynamic metadata generation function for dynamic routes
  • Image optimization for Open Graph images
  • Sitemap.xml generation (if not exists)
  • Robots.txt configuration (if not exists)

Include proper meta tag hierarchy, social preview testing notes, and SEO best practices. Implement dynamic metadata for pages with parameters. Ensure all metadata is type-safe with TypeScript.

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.
