Worked on backend reliability for the BloopAI/vibe-kanban repository by refactoring error handling in the Git service. Focused on unifying and simplifying the API error surface, the developer consolidated nested git and worktree errors into a single ApiError structure at the conversion boundary. This approach aligned with the WorkspaceManagerError pattern, reducing complexity and making server responses more predictable for clients. The work involved backend development and API design using Rust, with careful attention to error handling patterns. By documenting the new approach and preserving existing conventions, the changes improved maintainability and streamlined downstream client integration without introducing new features.
