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

widerruf-check 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.

/widerruf-check — Widerruf-Button & Einwilligungs-Entzug

Prüft, ob die Widerrufsmöglichkeit für erteilte Einwilligungen genauso einfach ist wie die Einwilligung selbst — die Kernpflicht aus Art. 7(3) DSGVO.

Gesetzesquellen: DSGVO Art. 7(3), TTDSG § 25 via rechtsinformationen-bund-de MCP.

Lücke: Die wichtigsten Umsetzungshinweise stammen aus den DSK-Orientierungshilfen (Datenschutzkonferenz) — diese sind nicht im MCP verfügbar. Relevante Dokumente: DSK Orientierungshilfe Telemedien, DSK Beschluss zu Cookie-Bannern 2022. Beim Nachschlagen von Implementierungsdetails darauf hinweisen und empfehlen, diese Dokumente manuell zu prüfen.


Step 0 — Route & Setup

Parse invocation args or user intent:

Pattern Modus
scan <url> oder URL gegeben URL-Scan (Cookie-Banner + Widerruf-UX)
audit <path> oder Dateipfad Code-Audit (Einwilligungs-Implementierung)
checklist UX-Checkliste ausgeben (vollständige Prüfliste)
Keine Args oder Freitext Vollprüfung (Scan + Checkliste + Empfehlungen)

Check MCP availability: attempt intelligente_rechtssuche with query DSGVO Artikel 7 Widerruf Einwilligung. If it responds, use it for law lookups. If unavailable, fall back to built-in knowledge.

Rechtliche Grundlage

Art. 7(3) DSGVO — Widerruf der Einwilligung (Kernsatz):

"Die betroffene Person hat das Recht, ihre Einwilligung jederzeit zu widerrufen. Durch den Widerruf der Einwilligung wird die Rechtmäßigkeit der aufgrund der Einwilligung bis zum Widerruf erfolgten Verarbeitung nicht berührt. Die betroffene Person wird vor Abgabe der Einwilligung hiervon in Kenntnis gesetzt. Der Widerruf der Einwilligung muss so einfach wie die Erteilung der Einwilligung sein."

TTDSG § 25 — Cookies & Tracking: Der gleiche Grundsatz gilt für Einwilligungen zum Setzen/Auslesen von Cookies und Tracking-Technologien. Der Widerruf muss jederzeit möglich und so einfach wie die ursprüngliche Einwilligung sein.

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.
