Install
Install DepWall and wire it into your shell and your agent. Node 20 or newer.
Requires Node 20 or newer. Check with node --version.
$ npm install -g depwall
$ depwall init
init installs PATH shims, adds them to your shell profile, and wires the Claude Code hook. It explains each change, asks before making it, and backs up every file it touches. It is safe to re-run.
$ depwall init --yes # no prompts
$ depwall init --project # project-local instead of user-level
$ depwall init --uninstall # undo everything
Windows
On Windows, init prints the PATH line for you to add rather than editing your PowerShell profile. Two shims are installed per manager: a .cmd for cmd.exe and PowerShell, and an extensionless script for Git Bash, which ignores PATHEXT.
