collectTools — gather decorated functions

Rust · crate toolnexus · SPEC §6

Sweep a module or class and collect every function marked as a tool.

What to use instead

Build a Vec<Tool> with define_tool / define_typed_tool and pass it as ToolkitOptions.extra_tools (or Toolkit::register it later). A function that returns the vector is the Rust spelling of a collector:

fn math_tools() -> Vec<Tool> {
    vec![
        define_tool("add", "Add a and b", None, |a, _c| async move { Ok::<_, String>((a["a"].as_f64().unwrap_or(0.0) + a["b"].as_f64().unwrap_or(0.0)).to_string()) }),
        define_tool("neg", "Negate n", None, |a, _c| async move { Ok::<_, String>((-a["n"].as_f64().unwrap_or(0.0)).to_string()) }),
    ]
}
