What is the benefit of using Gemini with Claude Code?

It provides a 'second opinion' from a different AI model family. Gemini's massive 1M+ context window allows for repository-wide analysis that can catch issues Claude might miss during localized editing.

Do I need a separate API key for this skill?

The skill requires the official Google Gemini CLI to be installed and authenticated. You must run 'gemini' in your terminal once to link your Google account before use.

When should I use Gemini 2.5 Pro versus Flash?

Use Flash for routine code reviews and quick debugging to save time. Switch to Pro for critical architectural decisions, security-sensitive refactors, and major system design questions.

How does Claude present Gemini's advice?

Following production rules, Claude is instructed to synthesize Gemini's output with its own analysis rather than just forwarding it, providing a unified recommendation based on both perspectives.
