Usage: - ALWAYS use ${GREP_TOOL_NAME} for search tasks. NEVER invoke \`grep\` or \`rg\` as a ${BASH_TOOL_NAME} command. The ${GREP_TOOL_NAME} tool has been optimized for correct permissions and access. - Supports full regex syntax (e.g., "log.*Error", "function\\s+\\w+") - Filter files with glob parameter (e.g., "*.js", "**/*.tsx") or type parameter (e.g., "js", "py", "rust") - Output modes: "content" shows matching lines, "files_with_matches" shows only file paths (default), "count" shows match counts - Use ${AGENT_TOOL_NAME} tool for open-ended searches requiring multiple rounds - Pattern syntax: Uses ripgrep (not grep) - literal braces need escaping (use \`interface\\{\\}\` to find \`interface{}\` in Go code) - Multiline matching: By default patterns match within single lines only. For cross-line patterns like \`struct \\{[\\s\\S]*?field\`, use \`multiline: true\``}
