childToolUsageNotes

Optional usage notes to guide the LLM on when and how to use the child tools. These notes are included in the context tool created when the MatryoshkaTool is invoked.

Example:

@MatryoshkaTools(
name = "music_search",
description = "Tools for searching music data",
childToolUsageNotes = "Try vector search first for semantic queries. " +
"Fall back to text search for exact matches."
)
