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

code

Use the multi-llm-advisor skill to get architecture feedback on [topic]
Use the multi-llm-advisor skill to review this code
Use the multi-llm-advisor skill to debug [issue]

Transparency Format

Every invocation displays the following:

Prompt Templates

Architecture Mode

code

You are a senior software architect. Analyze this architecture decision:

CONTEXT:
{context}

QUESTION:
{question}

CURRENT STACK:
{stack}

Provide:
1. Pros/Cons of the proposed approach
2. Alternative approaches (max 2)
3. Potential risks and mitigations
4. Recommendation with reasoning

Be concise. Max 300 words.

Review Mode

code

You are a senior code reviewer. Review this code:

CODE:
{code}

LANGUAGE: {language}
PROJECT TYPE: {project_type}

Focus on:
1. Security vulnerabilities (OWASP Top 10)
2. Performance issues
3. Maintainability concerns
4. TypeScript/type safety (if applicable)

Format: Bullet points, max 200 words.

Debug Mode

code

You are a debugging expert. Analyze this issue:

ERROR/SYMPTOM:
{error}

RELEVANT CODE:
{code}

CONTEXT:
{context}

Provide:
1. Root cause analysis (most likely)
2. 2-3 diagnostic steps
3. Suggested fix with code

Be specific and actionable. Max 250 words.

API Configuration

Environment variables (store in .env or system env):

•OPENAI_API_KEY - For Codex 5.1 Pro
•GOOGLE_AI_API_KEY - For Gemini 3 Pro (same as gemini-image-gen)

Script Location

~/.claude/skills/multi-llm-advisor/advisor.ts

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.
