class DecoratedTool — Callable wrapper around a tool function.

DecoratedTool

Inherits: BaseTool

Callable wrapper around a tool function.

Produced by the @tool decorator. When called, resolves the tool's declared credential groups, binds them to the tool credential context, runs the wrapped function, and tears the context down on completion (even on failure).

Instances are normally produced by the decorator rather than constructed directly.

Methods

__call__ — Invoke the tool.
invoke — Fill the inputs to this tool using the active LLM and then call it.

    **kwargs,
