Multi-LLM Brainstorm

Consult multiple external LLM providers simultaneously on a topic while Claude Opus performs its own independent research in parallel, then synthesize the findings from all participants.

Instructions

1. Parse the arguments:

   • If the first argument looks like a comma-separated provider list (e.g., gemini,codex or gemini,codex,ollama), use those as the external providers
   • If no provider list is given, default to gemini,codex
   • Valid external providers: gemini, codex, ollama
   • Everything after the provider list (or all args if no list) is the topic
   • Claude Opus is always a participant — it's not in the provider list because it runs inside the coordinator

2. Determine the brainstorm topic:

   • If the user provided a topic directly, use it
   • If the context is about code changes, gather the relevant diff with git diff and git diff --cached
   • If the context is a design/plan, gather the relevant documentation or conversation context

3. If no topic is clear, ask the user what they'd like to brainstorm about.

4. Launch the brainstorm-coordinator agent with the topic, the selected external providers list, and any gathered context. The agent handles:

   • Running its own Claude Opus research phase (Phase 3B — reads actual files, traces code, uses WebFetch/WebSearch on referenced external docs) in parallel with external dispatches
   • Constructing the prompt for each external provider
   • Sending to selected external providers in parallel (Phase 3A)
   • Synthesizing consensus, unique insights, and contradictions across all participants — Claude's verified findings are weighted higher than inferred ones
   • Producing prioritized recommendations
