toAiMessages

toAiMessages(messages: Message<unknown>[], options?: ToAiMessagesOptions): Promise<AiMessage[]>

• Keeps messages that have no text but carry content (images, files, links). Only messages with no usable content at all are skipped.
• Maps author.isMe === true to "assistant", otherwise "user"
• Uses message.text for content
• Appends bounded link metadata inside an explicit untrusted-content fence
• Includes image attachments and text files as FilePart
• Uses fetchData() when available to include attachment data inline
• Warns on unsupported attachment types (video, audio)

const result = await thread.adapter.fetchMessages(thread.id, { limit: 20 });
const history = await toAiMessages(result.messages);
const response = await agent.stream({ prompt: history });
