JJ Stacked PR Manager FAQs

Question 1

Why can't I run SPR commands directly in a .jj workspace?

Accepted Answer

SPR requires a .git directory to function correctly. This skill detects when you are in a workspace and instructs you to switch to the main colocated repository before running commands.

Question 2

What are stacked PRs in a jj repository?

Accepted Answer

Stacked PRs allow you to submit a series of dependent changes as individual pull requests that reference each other, enabling granular and manageable code reviews for complex features.

Question 3

How does the jj-spr skill prevent duplicate PRs?

Accepted Answer

The skill enforces the preservation of the 'Pull Request:' URL in commit messages. This URL is the only way SPR tracks local commits to GitHub PRs; deleting it during a 'jj describe' is the primary cause of duplicates.

Question 4

When should I use the -m flag with jj spr diff?

Accepted Answer

You should always use the -m flag when updating existing PRs. Without it, SPR prompts for an update message interactively, which can block automated workflows or AI interactions.

Question 5

What is the purpose of SPR's synthetic commits?

Accepted Answer

SPR pushes synthetic commits to GitHub rather than your raw local commits. This creates an append-only history that ensures clean diffs for reviewers, even as you rebase your local stack.
