Conversation
- Add Vertex AI Claude support: system message as top-level param, message normalization - GET /v1/models returns proxy-supported models (BIG_MODEL, SMALL_MODEL) - Model mapping: opus/sonnet -> BIG_MODEL, haiku/exact SMALL_MODEL -> Vertex - .env.example and .env.vertex.example for Vertex presets; VERTEX_LOCATION=global for Claude 4.5+ - Scripts: setup_env.sh (venv + uv), .hidden/check_vertex_claude.sh (quota project, list models), .hidden/fill_env_from_gcloud.sh; macOS-safe head/sed in check script - README: Vertex setup, Model Garden, gcloud vs key auth, troubleshooting - .gitignore: .env, *-key.json, .venv, .cursor/debug.log Co-authored-by: Cursor <cursoragent@cursor.com>
