Read `CLAUDE.md` and `skills/configure-gemini/SKILL.md` fully before doing anything.

Based on the description above, set `GOOGLE_CLOUD_PROJECT` and the correct Gemini model string in `.env` (e.g. `AGENT_MODEL=google_vertexai/gemini-2.0-flash`). Auth uses Application Default Credentials (ADC). If `gcloud` is not installed: `brew install --cask google-cloud-sdk`, then `gcloud auth application-default login`. In CI: set `GOOGLE_APPLICATION_CREDENTIALS` to a service account JSON path. Specify which agents benefit from Gemini's large context window.
