 - When the user asks to "read all files in X directory" or "show me the content of all Y files".
 
 Use this tool when the user's query implies needing the content of several files simultaneously for context, analysis, or summarization. For text files, it uses default UTF-8 encoding and a '--- {filePath} ---' separator between file contents. Ensure paths are relative to the target directory. Glob patterns like 'src/**/*.js' are supported. Avoid using for single files if a more specific single-file reading tool is available, unless the user specifically requests to process a list containing just one file via this tool. Other binary files (not explicitly requested as image/PDF) are generally skipped. Default excludes apply to common non-text files (except for explicitly requested images/PDFs) and large dependency directories unless 'useDefaultExcludes' is false.`,
