+"""ToolContext / ToolError / CancelFn - the sandboxed execution context every
+built-in tool runs against (moved out of ``core/tools.py`` in R05-T02).

+it without creating an import cycle back through ``core/tools.py``, which
+itself re-exports ``ToolContext``/``ToolError`` from here for the existing
+callers (``core/chat_agent.py``, ``core/code_agent.py``,
+``core/task_executors.py``) that do ``from .tools import ToolContext``.
