AI agents call trello_get_tasks to retrieve information from Trello without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and queries task data from Trello boards without creating, modifying, deleting, or executing any operations. The verb 'Get' combined with 'filtering options' indicates data retrieval. The blast radius of misuse is minimal—an agent might retrieve unwanted task information but cannot harm board state, delete data, or trigger external actions. This is a straightforward Read operation.
