# PR stacks

See how a conversation’s pull request relates to other PRs, beside the chat. The view reads GitHub metadata and links each PR to GitHub.

## Open the stack

Choose **View PR stack...** from the PR button’s menu or the **Code** menu. **View > PR stack** and **PR stack** in the side pane’s **+** open the same tab. It needs a conversation with a working folder and GitHub access through the GitHub CLI.

The current PR is highlighted. Each row shows its title, number, head and base branches, and whether it is open, a draft, merged or closed. Click a PR to open it on GitHub. **Refresh** asks for current metadata; changes to the conversation’s PR and completed turns also refresh a visible stack.

## Read the relationships

A confirmed parent appears above its dependents. Siblings share a parent; their order does not mean one depends on another. A standalone PR shows its base branch.

Confirmation uses GitHub’s repository, branch and commit metadata. A matching branch name alone is not enough. When several parents are possible, they stay separate links with an explanation. Missing metadata, a partial response, a lookup limit or a failed connection is shown explicitly.

A merged PR that GitHub has retargeted to the default branch may no longer reveal its historical parent. Dependents in a different fork repository are not searched. The view is bounded to 24 related PRs, so it can say the result is incomplete for a large stack.

Opening or refreshing the stack does not rebase, restack, push, publish or merge anything.

## Keep the tab available

Click the pin beside the tab’s name, or choose **Pin tab** in its right-click menu. The pin belongs to this conversation and survives reopening the window or restarting buddylist. **Unpin tab** returns it to its usual behavior; **Close** removes it and its pin.

An archived conversation can still read its stack. If its checkout is missing, a pinned tab explains why it is unavailable and can still be closed or unpinned. See the [conversation guide](conversations.md#the-side-pane-files-changes-and-checks-above-what-runs-below) for the other tabs and pin controls.
