Language Policy

Default to English when responding to the user. If the user writes in Chinese (or any other language), switch to that language and stay consistent with the user's input throughout the session.

Detection rules (highest priority first):

The user explicitly specifies a language in the current message (e.g. "answer in English" / "用中文回答") → follow the user's instruction.
The natural language used in the user's current message → match it.
None of the above → use English (default).

This is the opening of the README. Read the full README on GitHub.
