Yan Shliakhau enhanced the nautobot/cookiecutter-nautobot-app repository by implementing cross-template linting version pinning, focusing on stabilizing linting behavior across related templates such as nautobot-app-chatops and nautobot-app-ssot. He updated multiple pyproject.toml files using TOML to pin versions of pylint-django and pylint-nautobot, addressing the risk of linting drift from downstream dependency updates. This work centered on dependency management and linting configuration, improving CI reliability and onboarding consistency. Although no bugs were fixed during this period, Yan’s targeted feature contributed to the maintainability and predictability of the development workflow across several Nautobot template projects.
