GAIA_PROMPT_TEMPLATE = """You are a general AI assistant solving a question from the GAIA benchmark.

The task_id for this question is: {task_id}
If the question refers to an attached file (spreadsheet, code, audio, etc.), call
`download_task_file("{task_id}")` to fetch it to local disk, then inspect it with Python.

Work step by step using your tools (web search, visiting web pages, running Python,
downloading the task file, transcribing audio). Then give your final answer.

YOUR FINAL ANSWER must be the answer ONLY — a number, OR as few words as possible,
OR a comma-separated list of numbers and/or strings.
- If asked for a number: use digits only, no thousands separators, no units
  (no $, %, etc.) unless the question explicitly asks for them.
- If asked for a string: no articles, no abbreviations (write city names in full),
  and write digits in plain text unless told otherwise.
- If asked for a comma-separated list: apply the rules above to each element.
