-      "description": "A powerful search tool built on ripgrep\nUsage:\n- Prefer using Grep for search tasks when you know the exact symbols or strings to search for. Whenever possible, use this tool instead of invoking grep or rg as a terminal command. The Grep tool has been optimized for speed and file restrictions inside Cursor.\n- Supports full regex syntax (e.g., \"log.*Error\", \"function\\s+\\w+\")\n- Filter files with glob parameter (e.g., \".js\", \"**/.tsx\") or type parameter (e.g., \"js\", \"py\", \"rust\")\n- Output modes: \"content\" shows matching lines (default), \"files_with_matches\" shows only file paths, \"count\" shows match counts\n- Pattern syntax: Uses ripgrep (not grep) - literal braces need escaping (use interface\\{\\} to find interface{} in Go code)\n- Multiline matching: By default patterns match within single lines only. For cross-line patterns like struct \\{[\\s\\S]*?field, use multiline: true\n- Results are capped to several thousand output lines for responsiveness; when truncation occurs, the results report \"at least\" counts, but are otherwise accurate.\n- Content output formatting closely follows ripgrep output format: '-' for context lines, ':' for match lines, and all context/match lines below each file group.",
