VCS Detection Skill

Detect the version control system in use before running VCS commands.

Why This Matters

jj and git have different CLIs and workflows.
Running git commands in a jj repo (or vice versa) causes avoidable errors.
Some repos are colocated (both .jj/ and .git/ exist).

Detection Logic

Priority order:

jj root succeeds -> jj
else git rev-parse --show-toplevel succeeds -> git
else -> none

Detection Command

if jj root &>/dev/null; then echo "jj"
elif git rev-parse --show-toplevel &>/dev/null; then echo "git"
else echo "none"
fi

Common Command Mapping

Operation	git	jj
Status	`git status`	`jj status`
Log	`git log`	`jj log`
Diff	`git diff`	`jj diff`
Commit	`git commit`	`jj commit` / `jj describe`
Branch list	`git branch`	`jj branch list`
New branch	`git checkout -b <name>`	`jj branch create <name>`
Push	`git push`	`jj git push`
Fetch/Pull	`git fetch` / `git pull`	`jj git fetch`
Rebase	`git rebase`	`jj rebase`

Usage

Before VCS operations:

Run the detection command.
Use the matching CLI (jj or git).
If none, report that the directory is not version controlled.

Colocated Repos

If both .jj/ and .git/ exist, prefer jj commands and use git compatibility subcommands when needed.
