3-Round Brainstorm: Claude x Gemini (v2.1 — Two-Layer Architecture)

Setup (first run only)

Before first brainstorm, verify these prerequisites:

1. Find gemini.py — bundled at scripts/gemini.py relative to this SKILL.md. Locate it with:

   find . ~/.claude/skills -name gemini.py -path '*/gemini/*' 2>/dev/null | head -1
   

   Store the result as GEMINI variable for the session.

2. Check GOOGLE_API_KEY — must be set. Check with echo $GOOGLE_API_KEY. If empty, look for .env file and source it, or tell the user to get a key at https://aistudio.google.com

3. Check google-genai package — run python3 -c "from google import genai; print('OK')". If missing, run pip install google-genai.

If any check fails, tell the user what's missing and how to fix it. Do NOT proceed without all three.

Two-layer model architecture: Flash researches, Pro reasons. Claude orchestrates both.
