During July 2025, Chibicco worked on the team-mirai/policy repository, focusing on repository hygiene by removing an unused .github/.linkspector.yml configuration file. This targeted cleanup reduced clutter and minimized the risk of misconfiguration for the link-checking tool, directly supporting clearer tooling expectations and smoother onboarding for contributors. Chibicco applied skills in Git workflow management and configuration file handling, ensuring the repository remained maintainable and free from stale settings that could impact CI processes. While the scope of work was limited to a single feature and did not involve bug fixes, the change demonstrated careful attention to long-term repository health and clarity.
