Refactoring
Modernize legacy code safely
Tackle large refactors with confidence. Multiple agents work on different parts of your codebase, each in isolated worktrees.
Try multiple approaches at once
Not sure which refactoring strategy is best? Spawn separate workspaces for each approach and compare the results side by side.
See exactly what changed
Every modification is tracked. Review diffs across all workspaces before deciding what to merge.
Why Sonars for refactoring
Zero-risk experiments
Try different approaches in parallel worktrees. Compare results before committing to one.
Parallel migrations
Update multiple modules simultaneously. One agent per service, all working at once.
Review everything
See exactly what changed. Diff viewer shows every modification across all workspaces.
Keep your tools
Open any workspace in VS Code or Zed. Run your existing test suite as you go.
The refactoring workflow
Plan the migration
Identify modules to update. Each becomes its own workspace.
Refactor in parallel
Agents update each module. Tests run in isolation—no conflicts.
Review and test
Check each workspace's changes. Run integration tests before merging.
Merge incrementally
Bring changes together one module at a time. Ship with confidence.
Common questions
Can Sonars handle large-scale refactors?
Yes. Each workspace runs in its own git worktree, so you can refactor multiple modules simultaneously without any interference. Merge incrementally as each piece is ready.
How do I test changes before merging?
Each workspace is a complete working copy. Open it in your editor, run your test suite, verify everything works—then merge when you're confident.
What if the AI makes mistakes?
Everything is in version control. You review every diff before merging. If something's wrong, you can discard the workspace and try a different approach.
