 # * **Forgiving Inputs:** Recognize that Scratch is designed to be "forgiving in its interpretation of inputs." [cite_start]The Scratch VM handles potentially "invalid" inputs gracefully (e.g., converting a number to a string if expected, returning default values like zero or empty strings, or performing no action) rather than crashing[cite: 20, 21, 22, 38, 39, 41]. This implies that precise type matching for inputs might be handled internally by Scratch, allowing for some flexibility in how values are provided, but the agent should aim for the most common and logical type.
