Git Update
Safely update a Git repository by running fetch prune and bringing local main/master branches up to date with origin/main and origin/master without checking out those branches. Use when the user asks to update, refresh, fetch and rebase, or synchronize a local repository while preserving staged and unstaged work.

Git Update
Workflow
Use scripts/git_update.sh from the repository the user wants to update:
bash /Users/ralf/.codex/skills/git-update/scripts/git_update.shThe script:
- Runs
git fetch --prune. - If
origin/masterexists, updates localmaster. - If
origin/mainexists, updates localmain. - Creates a missing local branch at the matching remote branch without checking it out.
- Rebases existing local branch commits onto the matching remote branch in a temporary detached worktree, then updates the local branch ref.
Safety Rules
- Do not check out
mainormasterin the caller's working tree. - Do not stash, reset, clean, or otherwise rewrite the caller's staged or unstaged changes.
- If a rebase conflict or other error occurs, leave the caller's working tree untouched and do not move the local branch ref.
- If local commits exist that are not on the remote branch, keep them by rebasing them onto the remote branch instead of force-aligning the local branch to origin.
- In Codex sandboxed environments,
git fetch --prunemay fail when writing.git/FETCH_HEADor other Git metadata. Treat that as an expected sandbox permission issue, not as working-tree risk; rerun the same script with the appropriate escalation/approval.
Notes
- The usual result is that local
mainormasterpoints at the same commit asorigin/mainororigin/master. - When local commits are present, the local branch may intentionally remain ahead of origin after the rebase.
- If neither
origin/mainnororigin/masterexists, report that there is nothing to update after the fetch.
