What's Wrong?

/plugin install throws git-subdir plugin source requires git to be
installed and on PATH even when git is correctly installed and visible
via where.exe git, Get-Command git, and PowerShell.

What Should Happen?

Root Cause

In claude.exe (v2.1.114), the which('git') implementation (function
ox7) runs where.exe git to locate git, then passes results through a
filter (KD6) that removes any path located under the current working
directory:

function KD6(H) {
let $ = process.cwd().toLowerCase();
return H.filter((q) => {
let K = path.resolve(q).toLowerCase();
return path.dirname(K).toLowerCase() !== $ && !K.startsWith($ +
path.sep)
})
}

When the user's working directory is their home folder
(C:\Users\<name>) and git is installed at the default user-local
location (C:\Users\<name>\AppData\Local\Programs\Git), all paths
returned by where.exe git are under the home directory and get
filtered out, making git appear not found.

Steps to Reproduce

1. Install Git for Windows using the per-user installer (default on

many machines) → installs to
C:\Users\<name>\AppData\Local\Programs\Git

1. Launch Claude Code CLI from or with cwd set to C:\Users\<name> (the

home directory)

1. Run /plugin install <any-git-subdir-plugin>
2. Error: git-subdir plugin source requires git to be installed and on

PATH

Note: where.exe git, Get-Command git, and git --version all succeed —
git is genuinely on PATH.

Claude Model

None

Is this a regression?
