WHAT IT DOES

What gui_show_answer does on Anki

AI agents invoke gui_show_answer to trigger actions in Anki. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why gui_show_answer is rated High

Based on the tool name and context of sibling tools (gui_answer_card, gui_current_card), this tool likely triggers a GUI operation in Anki to display the answer side of the current flashcard. This constitutes an Execute action as it triggers an external UI operation. Confidence is low due to the empty description.

From the tool's definition Tool name 'gui_show_answer' suggests triggering a GUI action in Anki to reveal a card's answer; description is empty and uninformative.
