pub struct JsonPathTool { /* private fields */ }

JSON Path tool for extracting values from JSON.

Supports simple dot-notation paths like “user.name” and array access “[0]”.

Example

use vex_llm::JsonPathTool;
use vex_llm::Tool;

let jp = JsonPathTool::new();
let result = jp.execute(json!({
    "data": {"user": {"name": "Alice"}},

})).await?;
println!("{}", result["value"]); // "Alice"
