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
