mr

name: mr model: haiku context: fork description: Create a GitLab merge request using glab. Drafts title and description from branch history, then opens an MR with confirmation. allowed-tools: Bash(git *), Bash(glab mr *)

Invocation

/mr [options] — create a merge request for the current branch.

Optional args passed verbatim to glab mr create (e.g. --draft, --label foo, --reviewer username).

Instructions

Step 1: Gather context

Run in parallel:

git rev-parse --abbrev-ref HEAD
git log --oneline origin/HEAD..HEAD
git diff origin/HEAD..HEAD --stat

If the branch has no commits ahead of origin/HEAD, tell the user there is nothing to open an MR for and stop.

Step 2: Draft title and description

From the commit list and diff stat, draft:

• Title: imperative mood, under 72 chars. Use the single commit subject if there is only one commit; otherwise write a summary of the set.
• Description: a short summary of what changed and why, in plain prose. If there are multiple commits, list them as bullets. Keep it under 10 lines.

Step 3: Show the draft

Print the proposed title and description to the user. Do not pause to ask for approval — proceed directly to Step 4.

Step 4: Create the MR

Run:

glab mr create \
  --title "<title>" \
  --description "<description>" \
  --remove-source-branch \
  [any args the user passed]

The permission system will prompt for approval before running — do NOT use AskUserQuestion for this.

Step 5: Report

Print the MR URL returned by glab.
