Reviewer's GuideAdds a new Python automation script that uses the GitHub CLI to automatically fork the AppFlowy repo, create branches per issue, make a placeholder change, push to a fork, and open PRs, plus introduces an empty CONTRIBUTING.md file.

Hey - I've found 2 security issues, 3 other issues, and left some high level feedback:
Security issues:
- Detected subprocess function 'check_output' without a static string. If this data can be controlled by a malicious actor, it may be an instance of command injection. Audit the use of this call to ensure it is not controllable by an external resource. You may consider using 'shlex.escape()'. (link)
- Found 'subprocess' function 'check_output' with 'shell=True'. This is dangerous because this call will spawn the command using a shell process. Doing so propagates current shell settings and variables, which makes it much easier for a malicious actor to execute commands. Use 'shell=False' instead. (link)
General comments:
- The script currently hardcodes a personal access token into the remote URL, which is risky; rely on
gh-managed authentication (e.g.,gh repo set-defaultandgit pushwithout embedding${GITHUB_TOKEN}in the URL) rather than constructing credentialed remotes. - Blindly running
git remote add fork ...,git checkout -b ..., andgit push --forcewithout checking for existing remotes/branches or confirming the current branch can corrupt local state; add idempotent checks and avoid forced pushes by default. - Automating changes by appending to
CONTRIBUTING.mdas a placeholder modification is brittle and pollutes the repo; consider operating on a scratch file or using a well-scoped test file under a dedicated directory for automation experiments instead.

## Overall Comments
- The script currently hardcodes a personal access token into the remote URL, which is risky; rely on `gh`-managed authentication (e.g., `gh repo set-default` and `git push` without embedding `${GITHUB_TOKEN}` in the URL) rather than constructing credentialed remotes.
- Blindly running `git remote add fork ...`, `git checkout -b ...`, and `git push --force` without checking for existing remotes/branches or confirming the current branch can corrupt local state; add idempotent checks and avoid forced pushes by default.
- Automating changes by appending to `CONTRIBUTING.md` as a placeholder modification is brittle and pollutes the repo; consider operating on a scratch file or using a well-scoped test file under a dedicated directory for automation experiments instead.

**issue (bug_risk):** Environment GITHUB_TOKEN is only set for subprocesses, but later code expects it in the parent process environment.
Because the token is only set on the `env` passed to the subprocess, later calls to `os.environ.get('GITHUB_TOKEN')` will usually return `None`, which can break `remote_url` construction and auth. Either store the token in `os.environ` once (and reuse it), or thread it through your code explicitly (e.g., via return values or parameters) instead of re-reading from the environment.

**🚨 issue (security):** Embedding the token in the remote URL persists credentials in git config and logs, which is a security risk.
Since `gh` is already configured, you can rely on its credential helper instead of embedding the token in the URL. For example, use `gh repo clone` / `gh repo set-default` or configure a standard `git@github.com:...` SSH remote and let existing auth handle credentials, rather than constructing `https://user:token@github.com/...` manually.

**suggestion:** Appending a newline to CONTRIBUTING.md for each issue run will accumulate noise changes.
Because each run appends a blank line, this will create ever-growing, meaningless diffs in CONTRIBUTING.md and can interfere with real edits. Consider directing this placeholder change to a dedicated scratch file or a clearly marked, overwritable section instead of appending to this file on every run.
```suggestion
