Celeste Anglm enhanced the game-by-virtuals/game-python repository by expanding the Twitter plugin to support multiple media IDs per post, enabling richer media content in tweets, replies, and quote tweets. She refactored function signatures and API payload structures in Python to handle lists of media IDs, implementing validation logic to enforce Twitter’s four-media limit and updating tests to cover new behaviors and edge cases. Her work focused on backend development and API integration, ensuring compliance with external constraints while reducing input errors. The depth of the feature required careful coordination between payload design, input validation, and test-driven development practices.
