GREP_TOOL_DESCRIPTION = 'Search for a text pattern across files.\n\nSearches for literal text (
not regex) and returns matching files or content based on output_mode.\nSpecial characters like parentheses, brackets, pipes, etc. are treated as literal characters, not regex operators.\n\nExamples:\n- Search all files: `grep(pattern="TODO")`\n- Search Python files only: `grep(pattern="import",
glob="*.py")`\n- Show matching lines: `grep(pattern="error",
output_mode="content")`\n- Search for code with special chars: `grep(pattern="def __init__(self):"
)`'
