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-audit scanned grade A 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO-Audit

Diagnostiziere Crawling, Indexierung, Rendering, Leistung, Inhalte, interne Verlinkung, Internationalisierung, lokale Suche und Migrationen mit reproduzierbarer Evidenz.

Audit-Grundsätze

  1. Bei einer URL zuerst die aktuelle Website untersuchen.
  2. Beobachtung, Plattformbericht und Hypothese klar trennen.
  3. Keine Rankings, Sichtbarkeit, Trafficwerte oder Erholungsfristen versprechen.
  4. Suchmaschinenrichtlinien und Rich-Result-Voraussetzungen vor Empfehlungen in Primärquellen prüfen.
  5. Zeichenzahl, H1-Anzahl, Klicktiefe, Keywordplatzierung und Wortzahl als Heuristiken, nicht als universelle Rankingregeln behandeln.
  6. Zugangsdaten, private Daten, Analytics oder Search Console nur mit ausdrücklicher Berechtigung nutzen.
  7. Audit bleibt lesend; produktive Änderungen brauchen gesonderte Freigabe.
  8. Keine Doorway Pages, skalierten minderwertigen Orts-/Keywordvarianten, manipulativen Links oder fingierten Bewertungen empfehlen.

Kontext und Evidenz

Erfasse Website, Land, Sprache, Geschäftsmodell, Conversionziel, Umfang, wichtige Suchanfragen/Seiten, Wettbewerber, Baseline, Änderungen und verfügbare Erstanbieterdaten. Bei Einbrüchen Zeitpunkt gegen Releases, Migration, Tracking, Saisonalität, Nachfrage, manuelle Maßnahmen, Sicherheitsereignisse und dokumentierte Suchänderungen prüfen.

Evidenzreihenfolge: Search Console; Server/CDN-Logs und reproduzierbare HTTP-/Rendering-Prüfungen; validierte Analytics; Versions-/Deploymenthistorie; Crawl-Exporte; aktuelle Suchmaschinen-Dokumentation; Drittwerkzeuge ergänzend. site:-Abfragen sind kein Indexzähler.

Audit-Ablauf

1. Umfang und Baseline

Hostname-, Protokoll-, Subdomain- und Sprachvarianten bestätigen. Vorher-/Nachher-Zeiträume definieren. Nach Suchanfrage, Land, Gerät, Seitentyp, Verzeichnis und Darstellung segmentieren. Datenintegrität prüfen und je wichtigem Template repräsentative URLs wählen.

2. Crawlbarkeit und Indexierbarkeit

HTTP-Status, Redirectketten/-schleifen, Soft-404, robots.txt, Meta Robots, X-Robots-Tag, Canonicals, XML-Sitemaps, interne Auffindbarkeit, Orphans, Pagination, Facetten, Parameter und Infinite-Scroll-Fallback prüfen. Search-Console-Gründe und URL-Prüfungen stichprobenartig heranziehen. Canonicals sind Hinweise, keine Befehle; fehlende Self-Canonicals nur bei tatsächlichem Duplikationsrisiko beanstanden.

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.
