In December 2025, Anton focused on enhancing the Russian-language MDN documentation within the mdn/translated-content repository. He delivered a clarification for the Russian translation of the Web/API/URL documentation, addressing a translation ambiguity and correcting a typo in the comment section. Working primarily with Markdown and leveraging his skills in documentation and translation, Anton ensured the Russian content remained consistent with the English source, reducing confusion for Russian-speaking developers. The work, completed in collaboration with a co-author, improved the accuracy and clarity of technical documentation, though the scope was limited to a single feature and did not involve bug fixes.
