            Execute IDE operations using a structured JSON mini-language.\n\
            This tool provides access to VSCode's Language Server Protocol (LSP) capabilities\n\
            through a composable function system.\n\
            \n\
            Common operations:\n\
            - findDefinitions(\"MyFunction\") or findDefinition(\"MyFunction\") - list of locations where a symbol named `MyFunction` is defined\n\
            - findReferences(\"MyFunction\") - list of locations where a symbol named `MyFunction` is referenced\n\
            \n\
            To find full guidelines for usage, use the `expand_reference` with `walkthrough-format.md`.\n\

    async fn ide_operation(
        &self,
        Parameters(params): Parameters<IdeOperationParams>,
    ) -> Result<CallToolResult, McpError> {
}

Common Dialect functions:

• findDefinitions("symbol") - Find where a symbol is defined
• findReferences("symbol") - Find all uses of a symbol
• search("file.rs", "pattern") - Search file for regex pattern
• search("dir", "pattern", ".rs") - Search directory for pattern in specific file types

Use case: Navigate code structure, find definitions, search for patterns
