Codex Audit 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
Route auditing and debugging tasks to Codex CLI when:
- Autonomous iteration is needed (test-fix-retest loops)
- Sandboxed execution required for safety
- Rapid prototyping without approval overhead
Unique Capability
What Codex Does Better:
- Fully autonomous execution (no approval needed mid-task)
- Sandboxed isolation (no network, CWD only)
- Iterative debugging loops
- GPT-5-Codex optimized for agentic coding
When to Use
Perfect For:
- Automated test fixing
- Code auditing in isolation
- Rapid prototyping of features
- Refactoring with test verification
- Build failure recovery
- Security scanning in sandbox
Don't Use When:
- Need network access (sandbox disables it)
- Need to access files outside CWD
- Production debugging (use Claude with oversight)
- Complex multi-file coordination
Usage
Basic Audit
/codex-audit "Find and fix all type errors" --context src/
Test Fixing
/codex-audit "Fix failing tests" --context tests/ --max-iterations 10
Prototyping
/codex-audit "Build REST API with CRUD endpoints" --context .
Command Pattern
bash scripts/multi-model/codex-audit.sh "<task>" "<context>" "<task_id>" "<max_iterations>"
Safety Constraints
| Constraint | Value |
|---|---|
| Network | DISABLED |
| File Access | CWD only |
| Isolation | macOS Seatbelt / Docker |
| Max Iterations | 5 (configurable) |
Memory Integration
Results stored to Memory-MCP:
- Key:
multi-model/codex/audit/{task_id} - Tags: WHO=codex-cli, WHY=audit
Output Format
{
"raw_output": "Audit findings...",
"metrics": {
"files_analyzed": 15,
"findings_count": 7,
"fixes_applied": 5
},
"context_path": "src/",
"sandbox_mode": true
}
Handoff to Claude
After Codex audit completes:
- Findings stored in Memory-MCP
- Claude agents review findings
- Apply or escalate based on severity
// Claude agent reads Codex audit
const audit = memory_retrieve("multi-model/codex/audit/{task_id}");
if (audit.metrics.findings_count > 0) {
Task("Reviewer", `Review findings: ${audit.raw_output}`, "reviewer");
}
Integration with Audit Pipeline
# Phase 1: Theater detection (Claude)
/theater-detection-audit
# Phase 2: Functionality audit (Codex)
/codex-audit "Verify all functions work" --context src/
# Phase 3: Style audit (Claude)
/style-audit
