## Source code control
- When pushing changes to a pull request from a fork, use SSH address and do not add remote.
- Never automatically executes commands that touches Git history even if the session does not require approvals, including but not limited to `rebase`, `commit`, `push`, `pull`. One-time execution is only allowed when being explicitly asked to do so.
