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 B, and why

pseo-linking scanned grade B with 1 finding 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Build an internal linking system that creates strong topical authority, distributes link equity, and ensures every page is discoverable.

Core Principles

  1. Hub-and-spoke architecture: Category hubs link to all child pages; child pages link back to their hub
  2. Topical clustering: Pages within the same topic cluster interlink
  3. Every page reachable: No orphan pages - every page is linked from at least 2 other pages
  4. Crawl depth <= 3: Any page reachable within 3 clicks from the homepage
  5. Descriptive anchor text: Link text describes the target page, not generic "click here"

Architecture

Homepage
├── Category Hub A ──→ Page A1, A2, A3, ...
│   ├── Page A1 ──→ Hub A, A2, A3 (related)
│   ├── Page A2 ──→ Hub A, A1, A3 (related)
│   └── Page A3 ──→ Hub A, A1, A2 (related)
├── Category Hub B ──→ Page B1, B2, B3, ...
│   └── ...
└── Sitemap (links all hubs)

Implementation Steps

1. Breadcrumb Navigation

Build a breadcrumb component that:

  • Renders the full path: Home > Category > Current Page
  • Uses semantic HTML (<nav> with <ol>)
  • Generates BreadcrumbList schema markup (coordinate with pseo-schema)
  • Appears on every pSEO page
interface BreadcrumbItem {
  label: string;
  href: string;
}

function Breadcrumbs({ items }: { items: BreadcrumbItem[] }) {
  return (
    <nav aria-label="Breadcrumb">
      <ol>
        {items.map((item, i) => (
          <li key={item.href}>
            {i < items.length - 1 ? (
              <a href={item.href}>{item.label}</a>
            ) : (
              <span aria-current="page">{item.label}</span>
            )}
          </li>
        ))}
      </ol>
    </nav>
  );
}

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.
