<div class="api-provenance">Namespace Tracon · Assembly <code>Tracon.Abstractions.dll</code></div>

The settled outcome of a tool call whose timeout had already been reported.

```csharp
public sealed record LateToolCompletion : IEquatable<LateToolCompletion>
```

## Remarks

Written onto the EXISTING `tool_invocations` row, matched by
[LateToolCompletion.RunId](/api/tracon.latetoolcompletion/#Tracon_LateToolCompletion_RunId) and [LateToolCompletion.ToolCallId](/api/tracon.latetoolcompletion/#Tracon_LateToolCompletion_ToolCallId). A second row would count
as a second call in every per-tool total.

## Constructors
