RISK

Why TRELLO_ADD_CARDS_STICKERS_BY_ID_CARD is rated Medium

This tool creates visual elements (stickers) on cards, which is reversible modification of data. It falls under Write rather than Execute because it performs a standard data creation operation within Trello's intended API. The blast radius is low: sticker addition is a cosmetic change that doesn't affect core data, permissions, or financial state, and can be easily removed.

From the tool's definition Adds a sticker to a Trello card — creates or modifies card content reversibly with parameters for 'position, rotation, and z-index'
