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

app-agb 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 1mo 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.

Origin

This is a copy

86% identical to abnahme-testing — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

App AGB

Fachkern: App AGB

  • Klauselproblem (App AGB): prüft typische AGB-Risiken des Vertragstyps und erzeugt Klauselarchitektur, Red Flags und bessere Bedingungen.
  • AGB-Weiche: Einbeziehung (§ 305 BGB), überraschende Klausel (§ 305c BGB), Transparenz (§ 307 Abs. 1 S. 2 BGB), Inhaltskontrolle (§§ 307-309 BGB), Rechtsfolge (§ 306 BGB) und Prozess-/Verbandsrisiko sauber trennen.
  • Beleglogik: Originalklausel, Vertragsumfeld, Verwendungsnachweis, Verhandlungsspuren, Kundengruppe, Marktstandard und wirtschaftliche Wirkung als Matrix erfassen.
  • Arbeitsprodukt: Klauselampel, Redline, Ersatzformulierung, Verhandlungsposition und gerichtsfeste Kurzbegründung mit Live-Check amtlicher Normenquellen.

Prüfpfad

  1. Normenstand sichern: Vor tragenden Aussagen BGB §§ 305 bis 310 auf Gesetze im Internet prüfen; bei Verbandsrisiko UKlaG ergänzen.
  2. Anwendungsbereich: AGB-Eigenschaft, Einbeziehung, Individualabrede, Verbraucher-/Unternehmerstatus und Sondermaterie klären.
  3. Auslegung: kundenfeindlichste vertretbare Auslegung, Überraschung, Mehrdeutigkeit und Transparenz prüfen.
  4. Inhaltskontrolle: § 307 BGB als Grundprüfung, danach einschlägige Klauselverbote aus §§ 308, 309 BGB und § 310 BGB einordnen.
  5. Spezialfokus: Bei App AGB besonders auf wirtschaftlichen Zweck, versteckte Belastung, Verständlichkeit, Nachweisbarkeit und praxistaugliche Durchführung achten.
  6. Rechtsfolge: Unwirksamkeit, gesetzliche Ersatzregel, Rückzahlung, Vertragsfortbestand, Prozess- und UKlaG-Risiko prüfen.
  7. Verbesserung: mindestens eine sichere Ersatzfassung und bei Bedarf eine verhandelbare Fallback-Fassung formulieren.

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.
