Types

ChatToolCallItem:

Field	Type	Description
name	string	Tool or function name, shown in monospace. Required.
status	'pending' | 'running' | 'complete' | 'error'	Execution status. Omit it and the call is treated as complete.
target	string	What the tool acted on, such as a file path, a command, or a query.
duration	string	Execution time shown on the trailing edge, such as 1.2s.
node	string	Sandbox or worker name, shown as a neutral badge.
additions	number	Added lines or characters, rendered as +12.
deletions	number	Removed lines or characters, rendered as -3.
stats	string	Extra plain text after the label.
errorMessage	string	Error detail when status is error. Spoken to assistive tech and used as the status icon's tooltip.
key	string	Stable identity. Derived from the other fields when omitted.
resultDetail	string	Inline detail revealed when the row is expanded, such as a diff or command output. Its presence makes the row expandable. Use the detail slot instead for rich markup.
