# LLM Safety and Alignment Skill

## When to Use This Skill

Use this skill when:
- Building LLM applications serving end-users
- Deploying chatbots, assistants, or content generation systems
- Processing sensitive data (PII, health info, financial data)
- Operating in regulated industries (healthcare, finance, hiring)
- Facing potential adversarial users
- Any production system with safety/compliance requirements

**When NOT to use:** Internal prototypes with no user access or data processing.

## Core Principle

**Safety is not optional. It's mandatory for production.**

Without safety measures:
- Policy violations: 0.23% of outputs (23 incidents/10k queries)
- Bias: 12-22% differential treatment by protected characteristics
- Jailbreaks: 52% success rate on adversarial testing
- PII exposure: $5-10M in regulatory fines
- Undetected incidents: Weeks before discovery

**Formula:** Content moderation (filter harmful) + Bias testing (ensure fairness) + Jailbreak prevention (resist manipulation) + PII protection (comply with regulations) + Safety monitoring (detect incidents) = Responsible AI.

## Part 1: Content Moderation

### OpenAI Moderation API

**Purpose:** Detect content that violates OpenAI's usage policies.

**Categories:**
- `hate`: Hate speech, discrimination
- `hate/threatening`: Hate speech with violence
- `harassment`: Bullying, intimidation
- `harassment/threatening`: Harassment with threats
- `self-harm`: Self-harm content
- `sexual`: Sexual content
- `sexual/minors`: Sexual content involving minors
- `violence`: Violence, gore
- `violence/graphic`: Graphic violence

```python
import openai

    """

## Summary

**Safety and alignment are mandatory for production LLM applications.**

**Core safety measures:**
1. **Content moderation:** OpenAI Moderation API (input + output filtering)
2. **Jailbreak prevention:** Pattern detection + adversarial testing + defense in depth
3. **Bias testing:** Test protected characteristics (gender, race, age) + mitigation prompts
4. **PII protection:** Detect + redact + mask sensitive data
5. **Safety monitoring:** Track incidents + alert on thresholds + user feedback

**Implementation checklist:**
1. ✓ Moderate inputs with OpenAI Moderation API
2. ✓ Moderate outputs before returning to user
3. ✓ Detect jailbreak patterns (50+ test cases)
4. ✓ Test for bias across protected characteristics
5. ✓ Redact PII before API calls
6. ✓ Monitor safety metrics (incident rate, categories, severity)
7. ✓ Alert on threshold exceeds (>1% incident rate, critical incidents)
8. ✓ Collect user feedback (flag unsafe responses)
9. ✓ Review incidents weekly (continuous improvement)
10. ✓ Document safety measures (compliance audit trail)

Safety is not optional. Build responsibly.
