# EU AI Act Compliance

> **DISCLAIMER**: This skill provides guidance only. It does not constitute legal advice. Always verify with qualified legal professionals. The authors assume no liability for decisions made based on this skill's output.

## When to Use

Use this skill when:
- Building or deploying an AI system in the EU market
- Assessing whether your system falls under AI Act obligations
- Preparing disclosure notices for users interacting with AI
- Designing audit trail logging for AI systems
- Preparing documentation for EU AI Database registration

## Step 1: Risk Classification

Classify the AI system using the four-tier framework from Regulation (EU) 2024/1689:

### Prohibited (Article 5) — CANNOT be deployed
- Social scoring by public authorities
- Real-time remote biometric identification in public spaces (with exceptions)
- Emotion recognition in workplace/education
- Predictive policing based solely on profiling
- Untargeted facial image scraping

### High-Risk (Annex III) — Requires full conformity assessment
- Biometric identification and categorization
- Critical infrastructure management (water, gas, electricity, transport)
- Education and vocational training (admissions, assessment)
- Employment (recruitment, task allocation, termination)
- Essential services access (credit scoring, emergency services)
- Law enforcement (evidence evaluation, risk assessment)
- Migration and border control
- Justice and democratic processes

### Limited Risk (Article 50) — Transparency obligations
- Chatbots and conversational AI (must disclose AI nature)
- Emotion recognition systems (must inform subjects)
- Deep fakes and synthetic content (must label)
- AI-generated text published to inform public (must label)

### Minimal Risk — No specific obligations
- Spam filters, AI-enabled video games, inventory management

**Action**: Determine which tier applies. If High-Risk, proceed to Step 2. If Limited Risk, proceed to Step 3. If Prohibited, stop deployment.

## Step 2: High-Risk Compliance (Annex III Systems)

Required documentation and measures:

1. **Risk Management System** (Article 9)
   - Identify and analyze known and foreseeable risks
   - Estimate and evaluate risks from intended use and misuse
   - Adopt risk mitigation measures
   - Test to ensure residual risk is acceptable

2. **Data Governance** (Article 10)
   - Training data must be relevant, representative, and free of errors
   - Document data collection, preparation, and labeling practices
   - Address potential biases

3. **Technical Documentation** (Article 11)
   - System description, intended purpose, development process
   - Monitoring, functioning, and control measures
   - Detailed description of AI model (architecture, training, evaluation)

4. **Record-Keeping** (Article 12)
   - Automatic logging of events during system operation
   - Traceability of decisions
   - Minimum retention: duration appropriate to intended purpose

5. **Human Oversight** (Article 14)
   - Design for effective oversight by natural persons
   - Ability to override or reverse AI decisions
   - "Stop" button or equivalent procedure

6. **Accuracy, Robustness, Cybersecurity** (Article 15)
   - Achieve appropriate levels of accuracy for intended purpose
   - Resilience against errors, faults, and adversarial attacks
   - Cybersecurity measures proportionate to risks

## Step 3: Article 50 Transparency Obligations

All AI systems interacting with natural persons must:

### Chatbot/Agent Disclosure
```
This service uses artificial intelligence. You are interacting with an
AI assistant, not a human. Responses are generated automatically.
```

### Synthetic Content Marking
```
This content was created with the assistance of artificial intelligence.
```

### Voice Synthesis Disclosure
```
This voice is generated by artificial intelligence.
```

### Deep Fake / Synthetic Media
```
⚠️ This audio/video content was generated by AI (EU AI Act Art. 50).
```

**Implementation**: Add disclosure to:
- UI entry points (before first interaction)
- Generated content metadata (ID3 tags, EXIF, document properties)
- API responses (header or field)

## Step 4: Audit Trail Design

Design logging to satisfy Article 12 requirements:

```json
{
  "timestamp": "ISO-8601",
  "session_id": "uuid",
  "action": "ai_inference|user_interaction|decision|override",
  "model_id": "model-name-version",
  "input_hash": "sha256-of-input",
  "output_summary": "brief-description",
  "risk_tier": "high|limited|minimal",
  "human_oversight": true,
  "user_consent_recorded": true,
  "data_categories": ["text", "personal_data", "biometric"],
  "retention_days": 180
}
```

**Retention**: Minimum 180 days for high-risk systems. Align with GDPR data minimization.

## Step 5: EU AI Database Registration

High-risk AI systems must be registered in the EU database (Article 71) before being placed on the market. Prepare:
- Provider identification and contact details
- System description and intended purpose
- Conformity assessment status
- Member States where the system is available

## Key Deadlines

- **2 February 2025**: Prohibited practices effective
- **2 August 2025**: GPAI model obligations effective
- **2 August 2026**: High-risk system rules (Annex III) effective
- **2 August 2027**: Full application for all remaining provisions
