drawDash

Use after a draw-guess round has finished and the latest uploaded image from widget state has been inspected. This tool records ChatGPT's final guess for the round by comparing the provided guess against the stored session subject selected by play-round. It returns the guess, and whether the guess was exactly correct, then opens the guess-subject-result widget so the outcome is visible to the user. Call this tool instead of replying with a plain-text guess once the round widget has asked ChatGPT to decide what the user drew. Do not call it before a play-round session exists, for unrelated classification tasks, or when ChatGPT has not yet committed to one subject from the official list.

guess-subject

Use to start or restart a round of draw-guess, a lightweight drawing game played directly inside ChatGPT. This tool should be called when the user asks to play a guessing game, draw something for ChatGPT to identify, play Pictionary, or start another round of the same experience. Calling the tool renders the round widget, chooses a common subject on the server, stores it in session memory, starts a 60 second countdown, and lets the user sketch on a canvas using mouse, touch, trackpad, or stylus input. The widget handles the round flow itself: it decrypts the subject from tool response metadata, persists the remaining time, preserves unfinished strokes between reloads, locks input when the round is finished, uploads the completed drawing as an image file, and stores the latest file ID in widget state so ChatGPT can inspect it. After the upload settles, the widget waits four seconds and then presents an explicit button that sends a follow-up user message telling ChatGPT to decide what was drawn and call the guess-subject tool. At that point, ChatGPT should inspect the most recent uploaded image from widget state and call guess-subject with its best guess from the official subject list. Do not call this tool for unrelated drawing assistance, for static explanations of how the game works, or when the user explicitly does not want a widget. This tool returns empty structured content plus encrypted response metadata containing the round timestamp and chosen subject.
