Delegates large multi-file or whole-repo work to Gemini for architecture maps, refactor-impact analysis, and multi-document synthesis. Uses Gemini's large context window when the gemini CLI is connected; otherwise runs a scoped Claude pass over the most relevant files (narrower, lower-fidelity). Trigger when the user says "scan the whole repo", "long context", "all the files", "synthesize across these files", "gemini analysis", "map the architecture", "trace dependencies", or "what changes if I refactor X".
