Enum AgentRunStep 

pub enum AgentRunStep {
    CallModel {
        prompt: Message,
        history: Vec<Message>,
        turn: usize,
    },
    CallTools {
        calls: Vec<PendingToolCall>,
    },
    Done(PromptResponse),
}

What a driver must do next to advance an AgentRun.

Deliberately exhaustive: a driver must handle every step, so adding a variant is a breaking change by design.

Variants

CallModel

Send a completion request to the model and feed the result back via AgentRun::model_response.

Fields

prompt: Message

The prompt message for this turn (the latest message in the run).

history: Vec<Message>

The chat history preceding prompt: the caller-provided input history followed by messages accumulated by earlier turns.

turn: usize

One-based index of this model call within the run.

CallTools

Execute these tool calls and feed the results back via AgentRun::tool_results.

Fields

calls: Vec<PendingToolCall>

The tool calls of the current assistant turn, in emission order.

Done(PromptResponse)

The run is complete.
