Struct PendingApproval 

pub struct PendingApproval {
    pub id: String,
    pub name: String,
    pub args_json: String,
    pub title: String,
}

One tool call awaiting human-in-the-loop approval.

Emitted by run_turn when ToolExecutor::needs_approval returns true for a tool the model wants to call. The caller surfaces these to the human / approver, persists an approval_request event per entry, and re-drives the loop once a matching approval_response event lands.

id matches the provider’s tool-call id (so the assistant’s tool-use content block lines up with the eventual tool-result), and is also used as the request_id on the wire approval_request event payload.

Fields

id: String

Provider-assigned tool-call id; also used as the approval request_id.

name: String

Tool name, as advertised by ToolExecutor::specs. Raw machine identifier; the field of record for trust/audit (unchanged in the event log).

args_json: String

Arguments as a JSON string (opaque at this layer).

title: String

Human display label (MCP-style title) for the tool, carried from the harness wire for presentation in the approval prompt. May be empty when the harness produced no label; renderers derive one from name then.
