pub type AssistantContent {
  AssistantText(text: String)
  AssistantReasoning(
    text: String,
    signature: option.Option(String),
  )
  AssistantRedactedReasoning(data: String)
  AssistantToolCall(

}

Constructors

```
AssistantText(text: String)
```
```
AssistantReasoning(
  text: String,
  signature: option.Option(String),

Reasoning the model produced before answering. signature is the provider’s proof that the text is unmodified (Claude needs it to accept the reasoning back on the next turn).
```
AssistantRedactedReasoning(data: String)
```
Reasoning the provider returned encrypted (Claude’s redacted thinking). It must be sent back verbatim.
