Use case

Refactor without the fear

Hand Korden a refactor — rename, extract, restructure, modernize — and get back a contained pull request with tests, not a sprawling untested diff.

The problem

Refactors are risky precisely because they touch a lot. A big AI-generated change you can't trust is worse than no change.

How Korden helps

Korden scopes refactors on isolated worktrees, runs tests to guard behavior, and delivers the result as a reviewable PR. If you don't like it, you don't merge it — nothing was touched on your branch.

Isolated

Worktree sandbox

Refactors never touch your main branch until you merge.

Guarded

Behavior-checked

The Tester runs tests so refactors don't silently break things.

Reviewable

A clean diff

You read exactly what changed before it lands.

Frequently asked questions

Can Korden do large refactors?
Yes — and because each runs on its own worktree with tests, you can evaluate the result safely as a PR.
What if the refactor is wrong?
You simply don't merge it. Your branch is untouched until you approve.
