During December 2025, fpdy modernized the anomalyco/opencode repository by migrating the mise backend from the deprecated ubi backend to the GitHub backend for the sst/opencode project. This work involved updating both documentation and code examples, ensuring users could transition smoothly to the new, supported backend for managing the opencode toolchain. Leveraging skills in configuration management and documentation, and working with HTML, JavaScript, and Markdown, fpdy improved maintainability and reduced technical debt. The migration provided clear guidance for users and contributors, aligning the project with long-term reliability goals and enhancing the onboarding experience for future developers working with the toolchain.
