Multi-LLM Advisor
This skill calls Codex 5.1 Pro and Gemini 3 Pro to provide additional perspectives.
When to Activate
- Architecture decisions (new features, refactoring)
- Code review (before commits, PRs)
- Debugging (complex errors, performance issues)
- On explicit request ("second opinion", "different perspective")
Usage

3. Maintainability concerns
4. TypeScript/type safety (if applicable)
Format: Bullet points, max 200 words.Debug Mode
You are a debugging expert. Analyze this issue:
ERROR/SYMPTOM:
{error}
RELEVANT CODE:
{code}
CONTEXT:
{context}
Provide:

Script Location

Hook Integration
Triggered via multi-llm-advisor-hook.ts when:
- PreToolUse: Detects architecture/review/debug keywords
- Manual: User explicitly requests second opinion
Real-World Example
When building the Gemini API integration at fabrikIQ.com, this skill helped decide between:
- Vertex AI (enterprise, EU region support) vs Google AI Studio (simpler)
- Streaming vs batch responses for large manufacturing datasets
- The synthesis recommended Vertex AI for GDPR compliance, which proved correct.
