1PK19ihyTZUg5z05lThis finally got merged, can we start using it on this device?
I’ll inspect the merged change and the installed Jujutsu version, then enable it only if the local release supports it.

Add a workspace
By default, the new workspace inherits the sparse patterns of the current workspace. You can
override this with the `--sparse-patterns` option.
Usage: jj workspace add [OPTIONS] <DESTINATION>
Arguments:
<DESTINATION>
Where to create the new workspace
Options:
--name <NAME>
A name for the workspace
To override the default, which is the basename of the destination directory.
-r, --revision <REVSETS>
A list of parent revisions for the working-copy commit of the newly created workspace. You
may specify nothing, or any number of parents. ...

For more information, try '--help'.
The feature needs a newer JJ build than the installed 0.41.0; this device already meets its Git 2.42 minimum with Git 2.43.0. I’ll install the merged upstream revision and enable colocation globally so new JJ workspaces create matching Git worktrees by default.

<skill_content name="jj-guide"> # Skill: jj-guide # jj Guide for AI Agents Jujutsu (jj) is a Git-compatible VCS with mutable commits, automatic snapshotting, no staging area, and first-class conflicts. This skill teaches you how to use it safely from a non-interactive agent environment. If `.jj/` exists in the repo root, this is a jj repo. **Use `jj` commands, not `git`.** In a colocated repo (`.jj/` *and* `.git/`), git tools can read the state, but mutations should go through `jj` so the operation log stays consistent. ## Critical Rules - **NEVER** use interactive flags (`-i`, `--interactive`). TUI prompts hang in agent environments. This applies to `jj split -i`, `jj squash -i`, `jj commit -i`, `jj resolve`, `jj diffedit`, etc. - **ALWAYS** pass `-m "msg"` when describing/committing. Without `-m`, an editor opens and hangs. - **VERIFY** mutations with `jj st` and `jj log` after `squash`, `abandon`, `rebase`, `restore`, `commit`. ...
The source build keeps being killed by the command timeout before linking. I’ll replace it with the matching published 0.45.1 binary, which contains the merge and avoids compiling JJ locally.
Install a Rust binary... from binaries!
Usage: cargo-binstall [OPTIONS] [crate[@version]]...
Options:
-h, --help
Print help (see a summary with '-h')
Package selection:
--version <VERSION>
Package version to install.
Takes either an exact semver version or a semver version requirement expression, which
will be resolved to the highest matching version available.
Cannot be used when multiple packages are installed at once, use the attached version
syntax in that case.
--targets <TRIPLE>
Override binary target set.
Binstall is able to look for binaries for several targets, installing the first one it
finds in the order the targets were given. For example, on a 64-bit glibc Linux
distribution, the default is to look first for a `x86_64-unknown-linux-gnu` binary, then
for a `x86_64-unknown-linux-musl` binary. ...

The installed 0.45.1 release predates this September 4 merge: its help lacks --colocate. The checked-out merge revision does include it, so I’ll use an upstream preview asset if available; otherwise I’ll complete one cached source build rather than keep restarting it.

No upstream preview asset exists yet. The source checkout is present, so I’ll build it in place with a persistent target directory; that allows subsequent runs to reuse every compiled crate instead of restarting.

I’m creating a disposable colocated repository under the shared workspace directory. The test will create its new workspace at -r @- and assert the Git HEAD points to that requested parent, not the main workspace’s HEAD.

The first assertion used -r @-, which equals the main workspace’s exported Git HEAD by design, so it cannot establish the requested-revision distinction. I’ll rerun it with a deliberately different existing revision, then remove both disposable workspaces through JJ.

The upstream test confirms the invariant: a colocated workspace must export the -r target, not the main workspace tip. I’ll reproduce that exact non-tip case locally, then remove all validation state.

Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]'
The failed check selected root() with @---, so Git correctly had an unborn HEAD. I’ll rerun it against the actual non-tip first commit (@--); the expected invariant is a detached Git HEAD equal to that revision and different from the main worktree’s HEAD.

The non-tip validation passed: the new Git worktree HEAD matched the requested first revision (737ae9c9) and differed from the primary worktree’s second revision (83fa2350). I’ll remove the disposable JJ workspaces and their directories, then verify the installed configuration.

Installed upstream JJ revision 2133040a8b99df containing PR #9941.
jj --version: 0.45.1-2133040a8b99df306b3b6a199608b5ae669ae8a6git.colocate = truejj workspace add now supports --colocate and --no-colocate.Validated in a disposable repository: jj workspace add -r <revision> creates a registered Git worktree whose detached HEAD equals the requested revision, not the primary workspace’s HEAD. Removed all validation workspaces afterward.
New workspaces from an already colocated repository will now create matching Git worktrees by default.
