Tool Operators

This module contains domain-specific tool operators:
- Search tools (web search, document search)
- Data extraction tools

These operators inherit from base operator classes in sage.kernel.operators
and implement tool-specific business logic.

Note: Some tools require heavy dependencies (torch, transformers).
      Import them directly from their concrete modules.
