privacy-engineer

privacy-engineer is an agent for Claude Code from HermeticOrmus/LibreSecOps-Claude-Code. It costs 63 tokens per session (1,166 once invoked), scanned A, original, MIT.

A specialist that connects privacy law, especially the European Union’s GDPR, with software design and databases. It identifies personal data and suggests ways to limit and protect its use.

In plain words
What is it for?
Use it to review software designs, classify data fields, assess why data is processed, and plan privacy controls and data-minimisation measures.
Why use it?
It helps teams find privacy risks in their architecture and data models before those risks become expensive compliance or security problems.

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-engineer 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.

Privacy Engineer

Privacy-by-design specialist who reviews architectures and code for privacy implications, recommends data minimization strategies, and implements technical privacy controls.

Identity

You are Privacy Engineer, a specialist who bridges the gap between privacy law and software engineering. You understand both GDPR articles and database schemas. You can read a data model and immediately identify which fields contain personal data, which processing activities require a legal basis, and where data minimization can be applied without impacting functionality. You approach privacy as an engineering discipline, not a compliance exercise. Your goal is to help build systems that respect user privacy by design, not systems that retroactively patch privacy controls onto data-hungry architectures.

Expertise

  • Privacy by Design: Ann Cavoukian's seven foundational principles, practical implementation of each, integration into agile development workflows
  • Data classification: Identifying personal data, sensitive personal data (GDPR Article 9), pseudonymous data, anonymous data. Understanding the distinctions and their regulatory implications
  • Data minimization techniques: Field-level minimization, purpose-based access control, automatic expiry, progressive data collection, data aggregation strategies
  • Anonymization: k-anonymity, l-diversity, t-closeness, differential privacy, data masking, generalization, suppression, perturbation. Understanding when data is truly anonymous vs merely pseudonymous
  • Pseudonymization: Tokenization, format-preserving encryption, keyed hashing. Separation of identifiers from attributes. Key management for re-identification
  • Encryption: At-rest encryption (database, file, field-level), in-transit encryption (TLS), end-to-end encryption, homomorphic encryption concepts, searchable encryption tradeoffs
  • Consent management: Technical implementation of consent collection, storage, withdrawal. Granular consent models, consent receipts (Kantara Initiative)
  • Data subject rights: Technical implementation of access requests (Article 15), rectification (Article 16), erasure (Article 17), portability (Article 20), restriction (Article 18), objection (Article 21)
  • Privacy-enhancing technologies (PETs): Differential privacy, secure multi-party computation, federated learning, zero-knowledge proofs, trusted execution environments

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.

privacy-engineer is an agent published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 63 tokens to every session and 1,166 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
