Reviewing stacked pull requests

Note

This feature is in public preview and subject to change.

Each pull request in a stack shows only the diff for its layer. This means reviewers can request changes on any pull request independently. When a reviewer requests changes on a pull request mid-stack, you should make the fix on the branch that owns the change and rebase so the branches above it pick up your update.

Addressing review feedback

Navigate to the branch that needs changes.
Shell
```
gh stack checkout BRANCH-NAME
```
```
gh stack checkout BRANCH-NAME
```
You can also move through the stack with gh stack bottom, gh stack down, gh stack up, and gh stack top.

Make the requested fixes, then stage and commit them.

Shell

git add .
git commit -m "helpful-commit-message"

git add .
git commit -m "helpful-commit-message"

Cascade the changes through the rest of the stack. This rebases every branch above the changed one so they pick up your fix.
Shell
```
gh stack rebase
```
```
gh stack rebase
```
Push the updated stack. This uses --force-with-lease to safely update the rebased branches.
Shell
```
gh stack push
```
```
gh stack push
```

After you push, each pull request above the changed one reflects the update, and any CI checks are re-triggered.
