anonymization-alternative

anonymization-alternative is a skill for Claude Code, Codex from onfire7777/universal-ai-skills-library. It costs 80 tokens per session (3,424 once invoked), scanned A, original, MIT.

A framework for deciding whether personal data has been truly anonymized under GDPR, the European Union's data protection law. It covers techniques such as randomization and generalization and checks re-identification risk with k-anonymity, l-diversity, and t-closeness.

In plain words
What is it for?
It is for assessing anonymization, choosing de-identification techniques, and validating whether statistical or aggregate data can be retained.
Why use it?
It helps distinguish data that no longer identifies people from pseudonymized data that can still be linked back to them. This supports decisions about retaining data without treating it as personal data.

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

anonymization-alternative 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Anonymization as Retention Alternative

Overview

Anonymization transforms personal data into a form that no longer identifies or can reasonably be used to identify a natural person. Under GDPR Recital 26, truly anonymized data falls outside the scope of the regulation, meaning it can be retained indefinitely without a legal basis, without data subject rights applying, and without counting toward retention period obligations. However, achieving genuine anonymization — as opposed to mere pseudonymization — requires rigorous application of techniques validated against re-identification risk. This skill provides the assessment framework, implementation techniques, and validation methods for using anonymization as an alternative to deletion when retention of aggregate or statistical data serves a legitimate purpose.

GDPR Recital 26 — Anonymized Data Outside GDPR Scope

"The principles of data protection should therefore not apply to anonymous information, namely information which does not relate to an identified or identifiable natural person or to personal data rendered anonymous in such a manner that the data subject is not or no longer identifiable. This Regulation does not therefore concern the processing of such anonymous information, including for statistical or research purposes."

The critical test: whether the data subject is identifiable, taking into account "all the means reasonably likely to be used" either by the controller or "any other person" to identify the natural person.

Article 29 Working Party Opinion 05/2014 on Anonymization Techniques (WP216)

Adopted 10 April 2014, this Opinion establishes that effective anonymization must prevent:

  1. Singling out: Isolating some or all records which identify an individual in the dataset.
  2. Linkability: Linking at least two records concerning the same data subject (within the same dataset or between two separate datasets).
  3. Inference: Deducing, with significant probability, the value of an attribute from the values of a set of other attributes.
