gdpr-data-mapper

gdpr-data-mapper is a skill for Claude Code, Codex from JayRHa/AgentSkills. It costs 127 tokens per session (1,084 once invoked), scanned A, original, MIT.

A personal-data mapping assistant for GDPR, the European Union’s privacy law. It organizes how personal information is used and drafts records such as a Record of Processing Activities (RoPA), which documents an organization’s data processing.

In plain words
What is it for?
Use it to document processing activities, assess lawful bases, set retention periods, identify sensitive or children’s data, and prepare for data-subject requests.
Why use it?
It provides a structured view of where personal data goes, why it is used, how long it is kept, and how people can exercise their rights.

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

gdpr-data-mapper 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.

GDPR Data Mapper

Overview

Produce a clear, auditable map of personal-data processing and the core GDPR artifacts that depend on it. Output is a structured draft to be reviewed by a DPO or counsel — this skill does not give legal advice.

Keywords: GDPR, data mapping, RoPA, Article 30, record of processing, lawful basis, consent, legitimate interest, retention schedule, data subject rights, DSAR, data minimization, special category data, processor, controller, cross-border transfer, DPIA.

Workflow

  1. Inventory processing activities. List each distinct purpose for which personal data is used (e.g. "account management", "marketing emails", "fraud detection"). One activity per purpose.
  2. For each activity, capture the RoPA fields (see templates/ropa-template.md): controller/processor role, purpose, data categories, data subjects, recipients, retention, transfers, and security measures.
  3. Classify the data. Flag special category data (health, biometrics, religion, etc., Art. 9) and children's data — these need stronger justification. Apply data minimization: challenge every field ("why do we hold this?").
  4. Determine the lawful basis for each activity using the decision guide in references/lawful-basis-guide.md. Exactly one of the six bases per purpose; document the reasoning. For legitimate interest, note that a balancing test (LIA) is required.
  5. Set retention. Define a concrete retention period and trigger per data category (see references/retention-and-rights.md). "Indefinite" is not acceptable.
  6. Map data-subject rights readiness. For each activity, note how access, erasure, rectification, portability, restriction, and objection would be fulfilled — and any blockers (e.g. data in backups, third parties).
  7. Flag transfers and DPIA triggers. Note any transfers outside the EEA (and the safeguard: adequacy decision, SCCs) and whether the activity likely needs a DPIA (large-scale, special category, systematic monitoring).
  8. Summarize risks and gaps — missing basis, over-retention, undocumented processors, no DSAR path.

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.
