missingToolsConversionStrategy

Strategy used to determine how tool calls, present in the prompt but lacking definitions, are handled during agent execution.

This property provides a mechanism to convert or format missing tool call and result messages when they occur, typically due to differences in tool sets between steps or subgraphs while the same history is reused. This ensures the prompt remains consistent and readable for the model, even with undefined tools.

The specific behavior is determined by the selected MissingToolsConversionStrategy, which may either replace all tool-related messages or only those corresponding to missing tool definitions.
