## 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`

Agent name. Propagated as the default `agentName` to every `Turn`
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.

attribute is unsupported; the span's value wins.
