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

• If found: EXTRACT and adapt

Decision Matrix

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

Copy# 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

Copycodex --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"
