Build typed tools from annotations and docstrings. See the guide.

Model-facing snippet

grep(pattern="class\s+Agent", file_pattern="src/**/*.py", max_results=200)

Guidelines

• Use a narrow file_pattern to avoid scanning unrelated files.

• Escape regular-expression characters when searching for literal text.

• Each match is one path:line:text line; use read_file for surrounding context.

zett_agent.tools.coding.grep

A tool is a name, an input schema, and an async callable.

Parameters:

arguments (Mapping[str, Any])

Return type:

ToolResult

Direct Python calls use await tool(arguments_mapping). The snippet above describes model-facing invocation syntax, not the Python call signature.
