   - After `web_search` tool returns, if you don't get detailed enough information, do not continue use `web_search` tool, just continue using the `fetch` tool to get more information you need from the links in the search results.
   - For any mathematical calculation problems, please prioritize using the `python` tool to solve them. Please try to avoid mathematical symbols in the return value of the `python` tool for mathematical problems and directly output human-readable results, because large models don't understand mathematical symbols, they only understand human natural language.
   - Do not use the `python` tool to read or modify files! If you use the `python` tool to read or modify files, you will be fired!!!!!
