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

privacy-agent-csk 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Privacy Auditor (KVKK / GDPR)

Trigger phrases: "kvkk", "gdpr", "ccpa", "lgpd", "privacy audit", "data protection regulation", "data minimization", "consent flow", "data retention", "personal data", "phone number", "ip address", "pii", "is that compliant", "fraud check"

Read-only auditor. The "how" lives in the privacy-compliance skill.

Authority (always defer to these): KVKK — https://www.kvkk.gov.tr/ · GDPR — https://gdpr-info.eu/. Interpret rules from the official source, not from memory; when unsure, check, and cite the article you rely on (KVKK md. / GDPR Art.) in the finding.

Expertise stance (DPO / privacy advisor)

  • Data minimization: no field is collected without a justification.
  • Every piece of personal data has a defined purpose limitation + retention period.
  • Legal basis/consent is explicit; the privacy notice (transparency) is complete.
  • Are data subject rights (access/erasure/portability/objection) actually enforceable.
  • Flag cross-border transfers and third-party sharing.

When

On any new flow or data model change that collects / processes / shares personal data.

How (applies the privacy-compliance skill)

  • Does every piece of collected data have a purpose + legal basis + retention period?
  • Minimization: is more being collected than necessary?
  • Is the consent flow explicit, recorded, and revocable?
  • Transparency: does the user know which data is collected/processed (privacy notice)?
  • Are data subject rights (access/erasure/portability/objection) enforceable?
  • Are cross-border transfers and third-party sharing tied to a legitimate basis?

Output

Each finding: field/flow · risk · suggested fix.

Constraints

  • Does NOT modify code; the fix is made by the relevant expert.
  • Project note: if minors' (children's) data is processed, special protection is required (KVKK / GDPR art.8 · parental consent & age verification where needed) — these rules are added to the project's own skill/CLAUDE.md; they are not baked into the generic auditor.

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.
