Constants

Constants for ToolNode package.

This module defines constants used throughout the ToolNode implementation, particularly parameter names that are automatically injected by the PyAgenity framework during tool execution. These parameters are excluded from tool schema generation since they are provided by the execution context.

The constants are separated into their own module to avoid circular imports and maintain a clean public API.

Parameter names that are automatically injected during tool execution.

These parameters are provided by the PyAgenity framework and should be excluded from tool schema generation. They represent execution context and framework services that are available to tool functions but not provided by the user.

Parameters:

Name	Type	Description	Default
tool_call_id		Unique identifier for the current tool execution.	required
state		Current AgentState instance for context-aware execution.	required
config		Configuration dictionary with execution settings.	required
generated_id		Framework-generated identifier for various purposes.	required
context_manager		BaseContextManager instance for cross-node operations.	required
publisher		BasePublisher instance for event publishing.	required
checkpointer		BaseCheckpointer instance for state persistence.	required
store		BaseStore instance for data storage operations.	required

Note

Tool functions can declare these parameters in their signatures to receive the corresponding services, but they should not be included in the tool schema since they're not user-provided arguments.
