Struct ChatToolCallCompleteAction 

pub struct ChatToolCallCompleteAction {
    pub turn_id: String,
    pub tool_call_id: String,
    pub meta: Option<JsonObject>,
    pub result: ToolCallResult,
    pub requires_result_confirmation: Option<bool>,
}

Tool execution finished. Transitions to completed or pending-result-confirmation if requiresResultConfirmation is true.

For client-provided tools (whose tool call state carries a client ToolCallContributor with a clientId), the owning client dispatches this action with the execution result. The server SHOULD reject this action if the dispatching client does not match the contributor’s clientId.

Servers waiting on a client tool call MAY time out after a reasonable duration if the implementing client disconnects or becomes unresponsive, and dispatch this action with result.success = false and an appropriate error.

A client MAY also dispatch this action with a failed result ( result.success: false) for a tool call currently in auth-required status, to cancel that invocation without completing the pending MCP authentication challenge. This always transitions the tool call straight to completed, preserving the fields it had before pausing for auth; requiresResultConfirmation is ignored for this transition; the cancellation can never enter pending-result-confirmation, since there is no real result to review.

A successful result (result.success: true) is invalid for a tool call in auth-required status — execution never resumed after the challenge, so there’s nothing that could have produced it. The reducer MUST reject/ignore it as a no-op, leaving the tool call in auth-required. The client must resolve the auth challenge (chat/toolCallAuthResolved) before completing successfully.

Fields

turn_id: String

Turn identifier

tool_call_id: String

Tool call identifier

meta: Option<JsonObject>

Additional provider-specific metadata for this tool call.

Clients MAY look for well-known keys here to provide enhanced UI. For example, a ptyTerminal key with { input: string; output: string } indicates the tool operated on a terminal (both input and output may contain escape sequences).

result: ToolCallResult

Execution result

requires_result_confirmation: Option<bool>

If true, the result requires client approval before finalizing
