+**Sandboxed agent note:** if you are using Claude Code, Codex, Cursor, or another sandboxed AI runtime, updating `~/.zshrc` / `~/.bashrc` alone may not affect an already-running app session. After changing your shell profile, restart the IDE/agent, or launch it from a terminal where `MINIMAX_API_HOST` is already exported. If the tool has its own environment-variable settings, configure the value there as well.

 **IMPORTANT — When API Host is missing:**
 Before running any script, check if `MINIMAX_API_HOST` is set in the environment. If it is NOT configured:
 1. Ask the user which service endpoint their MiniMax account uses:
    - **China Mainland** → `https://api.minimaxi.com`
    - **Global** → `https://api.minimax.io`
-2. Instruct and help user to set it via `export MINIMAX_API_HOST="https://api.minimaxi.com"` (or the global variant) in their terminal or add it to their shell profile (`~/.zshrc` / `~/.bashrc`) for persistence
