ai-bias-special-category

ai-bias-special-category is a skill for Claude Code from mukul975/Privacy-Data-Protection-Skills. It costs 71 tokens per session (2,192 once invoked), scanned A, original, Apache-2.0.

A method for checking whether an AI system treats protected groups unfairly when it uses or infers sensitive personal information. It covers data such as health, religion, ethnicity, political views, and sexual orientation, along with related fairness concerns.

In plain words
What is it for?
Use it to assess bias, choose fairness measurements, detect unequal outcomes, plan mitigation, and prepare documentation for GDPR and the EU AI Act.
Why use it?
AI can introduce or worsen discrimination, while European privacy and AI rules place requirements on sensitive data and training-data management. This gives teams a way to examine those risks and document their response.

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

ai-bias-special-category 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.

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.

AI Bias Assessment for Special Category Data

Overview

AI systems can amplify, perpetuate, or introduce bias against protected groups defined by GDPR Art. 9 special categories (race, ethnicity, political opinion, religion, trade union membership, genetic data, biometric data, health, sexual orientation) and by EU equality law (gender, age, disability). The AI Act Art. 10 requires data governance practices for training data that address bias, while Art. 5 prohibits AI-based social scoring. This skill provides the methodology for detecting, measuring, and mitigating bias in AI systems that process or infer special category data, with documentation requirements meeting both GDPR and AI Act obligations.

Art. 9 Special Categories and AI Bias

Direct Processing of Special Category Data

When AI systems directly process Art. 9 data:

Category AI Bias Risk Example
Racial or ethnic origin Discrimination in hiring, credit, policing CV screening penalising names associated with ethnic minorities
Political opinions Political profiling, content suppression News recommendation amplifying or suppressing political viewpoints
Religious beliefs Service denial, discriminatory targeting Insurance pricing varying by religious affiliation
Trade union membership Employment discrimination Performance scoring penalising union activity
Genetic data Genetic discrimination in insurance/employment Health insurance pricing based on genetic predisposition
Biometric data Differential accuracy across demographics Facial recognition with higher error rates for darker skin tones
Health data Health-based discrimination Hiring algorithms penalising disability or mental health history
Sexual orientation Discrimination, outing Content recommendation inadvertently revealing sexual orientation

Proxy Inference of Special Categories

AI models frequently infer Art. 9 data from non-sensitive features:

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.
