Read a file and optionally edit it in one call. For single-file tasks, use this instead of separate read_file + edit calls. Returns file content. Edit params (old_string, new_string) are optional — omit them for read-only.

Edit multiple files when you already have their contents in context. ALWAYS use this instead of multiple separate edit calls. Each edit uses exact string or regex replacement. For read+edit combos, use multi_read_edit instead.

Read and optionally edit multiple files in one call. ALWAYS batch multi-file operations here instead of separate read_file/edit calls. Read-only ops return file content. Edit ops return compact results by default (no content) to save tokens — set include_content=true to get post-edit content, include_original=true for diffing.
