majiayu000 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
# 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
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 |
