Feature Verification Skill
Trigger
- •Keywords: verify, investigate, diagnose, check if working, anomaly, validate
- •User provides credentials for data sources
When NOT to Use
- •Need to modify data (this skill is read-only only)
- •Pure code review (use codex-review)
- •Feature development (use feature-dev)
Core Principle
code
ALL OPERATIONS MUST BE READ-ONLY
code
Claude independent analysis -> Form conclusion -> Codex third-perspective confirmation -> Integrated report
Workflow
code
Phase 1: Explore -> Understand system architecture, data flow, trigger points Phase 2: Plan -> Build verification checklist, present to user for confirmation Phase 3: Execute -> Execute read-only queries, record expected vs actual Phase 4: Analyze -> Claude independently forms diagnostic conclusion Phase 5: Confirm -> /codex-brainstorm third-perspective verification Phase 6: Integrate -> Synthesize dual perspectives, produce final report
Safety Rules
| Rule | Description |
|---|---|
| READ-ONLY | No write/update/delete operations allowed |
| PLAN-FIRST | Present verification plan before executing queries |
| CREDENTIAL-SAFETY | Do not expose full credentials in output |
| INDEPENDENT-FIRST | Claude forms conclusion first, then asks Codex to confirm |
Verification Checklist
| Category | Checks |
|---|---|
| Feature Checks | API endpoints, jobs, error handling |
| Data Checks | Collections, aggregations, external |
| Integration Checks | End-to-end flow |
Verification
- •Report includes Executive Summary + Status
- •Each check has expected/actual/status
- •Both Claude + Codex perspectives are documented
- •Recommendations split into Immediate / Further / Long-term

Examples
code
Input: /feature-verify User Auth
MongoDB: mongodb://...
{ANALYTICS}: project_id={PROJECT_ID}
Action: Explore -> Plan -> Execute queries -> Analyze -> Codex confirm -> Report
code
Input: verify user auth is working correctly Action: Phase 1-6 flow -> Output diagnostic report
