What problem does it solve?
You lose context when you paste Claude’s work into Gemini manually just to sanity-check a decision or review a diff.
Who is it for?
Claude-or-Cursor-first builders who keep Gemini CLI installed for alternate perspectives on code and design.
Skip if: Environments without Gemini CLI or Google account setup, or workflows that require only cloud API calls without a local CLI.
