Function: convertHistoryToDisplayItems()

convertHistoryToDisplayItems(messages): DisplayItem[]

Defined in: utils/utils.ts:135

Convert history messages to display items.

History returns:

• Assistant messages with toolCalls array (tool invocations)
• Tool messages (role='tool') with content (tool results)

For display, we need to:

1. Keep user/assistant text messages as ChatMessage
2. Convert each toolCall from assistant messages into a ToolCallMessage
3. Match tool result messages (role='tool') to their ToolCallMessage and update result
4. Filter out raw tool messages (role='tool') from display — they're merged into ToolCallMessage

Parameters

messages

ChatMessage[]

Returns

DisplayItem[]
