# Codex Zero Data Retention (ZDR) Skill



---

## LIBRARY-FIRST PROTOCOL (MANDATORY)

**Before writing ANY code, you MUST check:**

### Step 1: Library Catalog
- Location: `.claude/library/catalog.json`
- If match >70%: REUSE or ADAPT

### Step 2: Patterns Guide
- Location: `.claude/docs/inventories/LIBRARY-PATTERNS-GUIDE.md`
- If pattern exists: FOLLOW documented approach

### Step 3: Existing Projects
- Location: `D:\Projects\*`
- If found: EXTRACT and adapt

### Decision Matrix
| Match | Action |
|-------|--------|
| Library >90% | REUSE directly |
| Library 70-90% | ADAPT minimally |
| Pattern exists | FOLLOW pattern |
| In project | EXTRACT |
| No match | BUILD (add to library after) |

## Purpose

Execute Codex with Zero Data Retention for sensitive, proprietary, or regulated code where no data should be stored on OpenAI servers.

## Unique Capability

**What This Provides**:
- **No code retention**: Code not stored on OpenAI servers
- **Privacy-first**: GDPR, HIPAA compatible
- **Regulated industries**: Suitable for healthcare, finance
- **Proprietary code**: Safe for trade secrets

## When to Use

### Perfect For:
- Medical/healthcare code (HIPAA)
- Financial systems (PCI-DSS)
- Proprietary algorithms
- Trade secrets
- Government contracts
- Client code under NDA

### Trade-offs:
- Slightly slower (no caching)
- Same functionality otherwise

## Usage

```bash
# ZDR for sensitive code
/codex-zdr "Implement medical record encryption"

# ZDR with full-auto
/codex-zdr "Build payment processing module" --full-auto

# ZDR with sandbox
/codex-zdr "Audit financial calculations" --sandbox
```

## CLI Command

```bash
codex --zdr "Your sensitive task"

# Combined with full-auto
codex --full-auto --zdr "Build and test"

# Via script
CODEX_MODE=zdr bash scripts/multi-model/codex-yolo.sh "Task" "id" "." "5" "zdr"
```

## Compliance Notes

| Regulation | ZDR Suitability |
|------------|-----------------|
| GDPR | Compliant |
| HIPAA | Compliant |
| PCI-DSS | Suitable |
| SOC 2 | Suitable |
| FedRAMP | Check specifics |

## Memory Integration
