Ask Gemini

Get feedback from Google's Gemini CLI on code, architecture decisions, or implementation approaches.

Prerequisites

Observability

First: At the start of execution, display:

🔧 Skill "julien-workflow-advice-gemini" activated

• Gemini CLI installed: npm install -g @google/gemini-cli
• Authenticated: run gemini once to login with Google account
• Verify: gemini --version

When to Use

• Want a second opinion on code quality
• Need architectural review
• Comparing implementation approaches
• Code review before commit

How to Invoke

The user will ask something like:

• "ask gemini what it thinks about this code"
• "get gemini's opinion on this approach"
• "demande à gemini de reviewer ce fichier"

Execution

For file review

gemini "Review this code and provide 3 specific improvements: $(cat <file_path>)"

For architectural questions

gemini "<user's question about architecture or approach>"

For comparing approaches

gemini "Compare these two approaches and recommend which is better: Approach A: <desc> vs Approach B: <desc>"

Output Format

Present Gemini's response clearly to the user. If Gemini suggests improvements, summarize them as actionable items.

Examples

File review

User: "demande à gemini ce qu'il pense du semantic-skill-router.py"

gemini "Review this Python script for a semantic routing system. List 3 improvements for production use: $(cat scripts/semantic-skill-router.py)"

Architecture question

User: "ask gemini if I should use Redis or in-memory cache"

gemini "Compare Redis vs in-memory caching for a CLI tool that routes user prompts. Consider: startup time, complexity, persistence needs."

Troubleshooting

| Error | Cause | Fix | |-------|-------|-----| | gemini: command not found | CLI not installed | npm install -g @google/gemini-cli | | Authentication required | Not logged in | Run gemini interactively, login with Google | | Response timeout | Large file or slow network | Reduce file size or retry | | Rate limit exceeded | Too many requests | Wait 1 minute, retry |

Notes

• Gemini has 1M token context window
• Default model: Gemini 2.5 Pro
