In March 2025, Mittyta contributed to the moysklad/api-remap-1.2-doc repository by developing the AppChangePermissions notification feature, which informs users about changes in application permissions. They designed and documented the new notification type, detailing its purpose, attributes, and providing a clear JSON response example using Markdown. Mittyta also addressed a documentation bug by correcting the JSON structure to ensure accurate formatting, improving clarity for developers integrating permission-change events. Their work focused on maintaining documentation consistency and repository hygiene, demonstrating attention to detail in both technical writing and version control practices over the course of the month-long engagement.
