title: Teammates and CI
description: Under CI grove runs your command untouched, and --if-available asks for the same anywhere, so one script serves teammates who never installed it.

Adopting grove isn't a team decision, because a script that runs through it keeps working for anyone who doesn't have it.

## Under CI

With `CI` set in the environment and no daemon to talk to, `grove exec` runs the command with its environment untouched instead of failing. A build service is the authority on its own environment and grove is not running there. `CI` empty, `0`, or `false` counts as unset; anything else counts as CI, which is how the build services set it.

This only decides what happens when no daemon answered. A daemon deliberately running in CI is used like any other.

## For a teammate who never ran grove install

`--if-available` asks for the same tolerance anywhere:

```json package.json
{
  "scripts": {
    "dev": "grove exec --if-available -- next dev"
  }
}
```

A teammate who never ran `grove install` runs `pnpm dev` and gets `next dev` on whatever port it picks, as before. Someone who did gets a hostname. The script is the same, and there's no branch in it.

The binary still has to be there to step aside, which is what the npm package is for: list `@grove-sh/cli` as a dev dependency and `grove` resolves from `node_modules/.bin` for everyone. When grove has to name a command in an error, it names the one you can run, so inside a package that's `pnpm grove doctor` rather than `grove doctor`.

## Two versions of grove in one project

A workspace can resolve a different copy of grove per package, and the one that decides is under the package whose script starts the stack, not the one you type. Two versions can derive a worktree's context differently, and since ports come from the context, a worktree that changes name changes every port with it. `grove doctor` reports what the project installs, and [Troubleshooting](/guides/troubleshooting#when-two-groves-disagree-about-this-worktree) says what that looks like.
