## Properties

### agentDescription

> `optional` **agentDescription**: `string`

Human-readable agent description. Propagated as the default
`agentDescription` to every `Turn` created via `startTurn()` unless
the turn sets its own; emitted on each turn's `invoke_agent` span as
`gen_ai.agent.description`.

Defined in: [src/genai/conversation.ts:31](https://github.com/wandb/weave/blob/8c5f077eb11c42b84000726ff20504abc728d3fb/sdks/node/src/genai/conversation.ts#L31)

***

### agentId

> `optional` **agentId**: `string`

Stable agent identifier. Propagated as the default `agentId` to every
`Turn` created via `startTurn()` unless the turn sets its own; emitted
on each turn's `invoke_agent` span as `gen_ai.agent.id`.

Defined in: [src/genai/conversation.ts:16](https://github.com/wandb/weave/blob/8c5f077eb11c42b84000726ff20504abc728d3fb/sdks/node/src/genai/conversation.ts#L16)

### agentName

> `optional` **agentName**: `string`

created via `startTurn()` unless the turn sets its own; emitted on
each turn's `invoke_agent` span as `gen_ai.agent.name`.

Defined in: [src/genai/conversation.ts:23](https://github.com/wandb/weave/blob/8c5f077eb11c42b84000726ff20504abc728d3fb/sdks/node/src/genai/conversation.ts#L23)

***

### attributes

> `optional` **attributes**: `Attributes`

Custom attributes stamped on every span the conversation emits.

A key here that collides with a span's own `gen_ai.*` / `weave.*`
attribute is unsupported; the span's value wins.
