Hybrid Multi-Model Routing via /gemini Slash Command: Claude for Logic, Gemini 3 Pro for Visual

paddo.dev·medium signal

paddo.dev documents a concrete pattern for spawning Gemini 3 Pro from within Claude Code via a custom /gemini slash command backed by @google/gemini-cli and pngpaste for screenshot capture. The routing logic is: Claude handles backend logic, refactoring, and debugging; Gemini handles visual analysis (screenshot-to-fix in one shot), UI generation, and 1M-context research tasks. A 'bias toward action' principle applies—when intent is clear (e.g., 'fix the spacing'), Gemini applies changes directly without requesting approval, preserving workflow velocity.
