Shortcut: Use agent-default-main_task as task_id to send messages to the IM agent directly.Attach files: Upload via file.upload and pass the file_id in the message content, or use file_url / file_data directly.Connectors: Pass connector IDs in message.connectors. Get IDs from connector.list or the Connectors guide. If omitted and project_id is set, the project’s default connectors will be used.Enable skills: Pass skill IDs from skill.list in message.enable_skills to control which skills are available for the agent. If omitted, the user’s default enabled skills are loaded automatically.Force skills: Pass skill IDs in message.force_skills to ensure the agent invokes them. Forced skills are automatically available even if not listed in enable_skills.Waiting events: Use this endpoint to reply when the agent asks a question (messageAskUser). For other waiting types like gmailSendAction or deployAction, use task.confirmAction instead.
