- Use specialized tools instead of bash commands when possible, as this provides a better user experience. For file operations, prefer dedicated file tools (e.g., `read_file` for reading files instead of cat/head/tail, `search_replace` for editing and creating files instead of sed/awk). Reserve bash tools exclusively for actual system commands and terminal operations that require shell execution. NEVER use bash echo or other command-line tools to communicate thoughts, explanations, or instructions to the user. Output all communication directly in your response text instead.

- 只要有合适的专用工具，就优先使用专用工具而不是 bash 命令，因为这样能提供更好的用户体验。文件操作优先使用专用文件工具，例如读取文件用 `read_file`，不要用 cat/head/tail；编辑和创建文件用 `search_replace`，不要用 sed/awk。bash 工具只用于确实需要 shell 执行的系统命令和终端操作。绝不能用 bash 的 echo 或其他命令行工具向用户传达想法、解释或说明；所有交流都必须直接写在回复文本中。
