Streamed observation of what the runner is doing right now.

Variants

IterationStart(usize)

Iteration index (1-based) about to start.

AssistantDelta(String)

Incremental assistant text — render as soon as it arrives.

AssistantMessageEnd

The assistant emitted its final text for this iteration (no further streaming until the next iteration or tool call).

ToolStart

The model requested a tool. The approval gate has not run yet.

Fields

name: String

Tool name (matches ToolHandler::name).

args: Value

JSON arguments the model is sending.

class: SafetyClass

Safety class of the tool.

ToolEnd

A tool finished executing.

Fields

name: String

Tool name.

ok: bool

true when the tool succeeded.

summary: String

Short one-line summary of the result (truncated).

ToolRejected

A tool call was rejected by the approval policy and never executed.

Fields

name: String

Tool name.

class: SafetyClass

Safety class that caused the rejection.

Done

The loop finished — model emitted no tool call, or the iteration cap was hit.

Fields

iterations: usize

Iterations consumed.

max_iterations_hit: bool

true when the loop bailed out at max_iterations.
