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
