# Class: WeaveAdkPlugin

> TypeScript SDK reference

[weave](../) / WeaveAdkPlugin

ADK plugin that emits runner invocations, agent runs, model calls and tool
executions as GenAI-semconv OTel spans on Weave's agents pipeline.

Implements the full `BasePlugin` surface structurally. ADK's PluginManager
invokes every callback, so all are present even where a callback is a no-op.
ADK treats any non-`undefined` return as a short-circuit, so every callback
swallows its own errors and returns `undefined`.

***

### finishInterruptedInvocation

▸ **finishInterruptedInvocation**(`invocationId`): `void`

Finalizes a run that never reached `afterRunCallback`. ADK only dispatches
`afterRunCallback` after the event loop drains normally, so a consumer that
breaks out of `runAsync` early — or an aborted run — leaves the invocation
(and its spans) open. The auto-instrument runner wrapper calls this from a
`finally` to close them as interrupted. Idempotent: a no-op once the run
has already finished (the common, fully-consumed case).

#### Parameters

| Name           | Type     |
| :------------- | :------- |
| `invocationId` | `string` |

#### Returns

`void`
