## Pre-Review Checklist

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.

In my trials so far, Jules struggles to run the repo tooling commands once it has moved into a target directory, because it frequently tries to use a root-relative path instead of an absolute path. To try to reduce that problem, this instructs the agent to explicitly create an alias so that the later commands that reference REPO_ROOT as a placeholder will, hopefully, be run exactly as written in the examples instead.

Also, to reduce unnecessary working directory confusion, switch to `dart pub get -C` instead of `cd` followed by `dart pub get` for initializing the tooling. (Also makes the same change to the tool README, because why not have humans run one command instead of three.)
