Claude Code sends Claude a short description of each tool, which tells Claude what the tool does and how to use it.\n\nThe Edit tool's description has been rewritten. Its opening line used to read \"Performs exact string replacements in files.\" It now reads \"Performs exact string replacement in a file.\" The new wording describes one replacement in one file, where the old wording described several replacements across several files.\n\n**Why**\n\nThe tool descriptions are part of Claude's instructions, so a change to their wording can change how Claude goes about editing. In practice the new line frames each edit as a single change to a single file.\n\n- Area: Tools\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5"}
