Struct ToolContext 

pub struct ToolContext {
    pub provider: ProviderKind,
    pub model: String,
    pub round: usize,
    pub tool_name: String,
    pub tool_call_id: String,
}

Metadata passed to each tool handler invocation.

Example

use rai_sdk::{JsonSchema, Tool};
use serde::Deserialize;

#[derive(Deserialize, JsonSchema)]
#[schemars(crate = "rai_sdk::schemars")]
struct EchoArgs {
    value: String,
}

let _tool = Tool::new("echo")
    .description("Return the input together with model metadata")
    .handler(|args: EchoArgs, ctx: rai_sdk::ToolContext| async move {
        Ok(format!("{} via {}", args.value, ctx.model))
    })?;

Fields

provider: ProviderKind

Provider that requested the tool call.

model: String

Model ID that requested the tool call, as sent on the wire.

round: usize

Zero-based index of the tool-calling round within the current request.

Useful for detecting repeated calls and for bounding work in handlers that may be invoked several times in one generation.

tool_name: String

Name of the tool being invoked.

tool_call_id: String

Provider-assigned identifier for this specific tool call.
