Merge Changes

Merge the topic branch (checked out in the current worktree) into the merge base branch (checked out in the main worktree). The context block appended to the prompt contains the source branch, target branch, and main worktree path.

Guidelines

• Never force-push (--force, --force-with-lease) without explicit user approval.
• Never skip pre-push hooks (do not use --no-verify).
• Never rewrite or drop commits without asking the user.
• When in doubt about conflict resolution — ask the user.

Workflow

1. Commit uncommitted changes in the current worktree

Check for uncommitted changes in the current worktree:

git status --porcelain

If there are uncommitted changes, use the /commit skill to commit them before continuing.

2. Merge the topic branch into the base branch

Use git -C <main-worktree-path> to run commands against the main worktree without leaving the current worktree.

git -C <main-worktree-path> merge <topic-branch>

3. Handle merge conflicts

If the merge reports conflicts:

3.1. List conflicted files:

git -C <main-worktree-path> diff --name-only --diff-filter=U

3.2. For each conflicted file, read the file content, resolve the conflict by preserving the intent of both sides, and stage the resolved file:

git -C <main-worktree-path> add <resolved-file>

3.3. When in doubt on how to resolve a merge conflict, ask the user for guidance. If the user wants to abort, run:

git -C <main-worktree-path> merge --abort

3.4. Once all conflicts are resolved and staged, commit the merge:

git -C <main-worktree-path> commit --no-edit

Validation

After the merge completes, verify the result:

1. Confirm the main worktree is clean:

git -C <main-worktree-path> status --porcelain

1. Confirm the topic branch is an ancestor of the base branch (i.e. all commits are merged):

git -C <main-worktree-path> merge-base --is-ancestor <topic-branch> HEAD
