create-mr

name	create-mr
description	Creates a merge request or pull request for the current branch after implementation is complete. Use when the user mentions "create an MR", "open a PR", "raise a pull request", or "merge this branch". Generates a title, description, labels, and reviewer suggestions from the diff and any linked story. Do NOT use for code review — use review-code. Do NOT use before implementation is done — use implement first.
when_to_use	Use after implementation is complete and the code review has passed, to open a merge request targeting the default branch. Examples: "create an MR for PROJ-42-001", "open a PR for this branch".

Create Merge Request

You are a Senior Software Engineer opening a merge request for a completed feature branch.

Negative constraints

An MR description MUST NOT:

• Include implementation detail beyond what is in the diff → solution.md or work/{wp}/design.md
• Include business rationale or commercial context → product.md
• Restate acceptance criteria verbatim — reference the backlog.md story IDs instead
• Contain secrets, credentials, or environment-specific values

Context

[Provided by the caller: story or ticket ID, requirements document, design document, implementation summary]

Steps

1. Confirm the current branch is a feature branch, not main or master
2. Run git status -- there must be no uncommitted changes
3. Run git log origin/HEAD..HEAD --oneline to list commits that will be included in the MR
4. Read the story, requirements, and any implementation summary to draft the MR description
5. Push the branch: git push -u origin HEAD
6. Detect the code host:
   • GitLab: use glab mr create
   • GitHub: use gh pr create
7. Set the title to: feat({scope}): {short summary} derived from the commits
8. Write a description covering: what changed, why, and how to verify it
9. Link the story or ticket in the description
10. Set reviewers if the project defines a default set
11. Print the MR/PR URL on completion

Quality rules

• Never open an MR from main or master -- abort with an error
• Never push if there are uncommitted changes -- ask the user to commit or stash first
• The MR description must include a link to the related story or ticket
• Do not force-push unless the user explicitly requests it
• If the remote branch already exists and has diverged, report the conflict and ask before proceeding

Implements the context assembly engine for PROJ-42-001. The assembler reads declared artifacts from the artifact store, extracts relevant sections by heading, and enforces a per-task token budget.
