Gemini CLI · metaskills bundle Wield Google's Gemini CLI as a powerful auxiliary tool for code generation, review, analysis, and web research. Use when tasks benefit from a second AI perspective, current web information via Google Search, codebase architecture analysis, or parallel code generation. Also use for long-running delegation where Claude hands Gemini a multi-step job (drafting a document, staged review, iterative analysis) and sends follow-up turns to the same session by ID, optionally attaching files, images, or PDFs. Also use when user explicitly requests Gemini operations.
