Git Merge to Main

Overview

Merge the current branch into main, then delete the source branch locally because it's now fully merged, unless the source is protected. Safe by design — never --force, never -D (only -d), never auto-resolves conflicts, never auto-pushes.

Announce at start: "I'm using the git-merge-to-main skill to merge <source-branch> into main and delete it unless it is protected."

Protected Source Branches

The following source branch names are protected and must be kept locally after the merge:

main, master, dev, develop, development, stg, stage, staging, root

If src is a protected source branch, still show the merge plan and proceed after confirmation, but skip the local delete step. Do not run git branch -d "$src" for protected branches, and do not suggest remote deletion for them.

Preconditions

Run these checks before touching anything. Fail closed on any violation — report and stop.
