Step 1 — Gather Context

git branch --show-current
git log origin/develop..HEAD --oneline 2>/dev/null || git log --oneline -15
git diff origin/develop...HEAD --stat 2>/dev/null || git diff HEAD~5...HEAD --stat
git diff origin/develop...HEAD 2>/dev/null || git diff HEAD~5...HEAD

Also read the PR template:

cat .github/PULL_REQUEST_TEMPLATE.md

Step 2 — Determine Labels

Read references/labels.md and select 1–2 appropriate labels based on the nature of the changes. Read references/commit-conventions.md for commit type and scope naming rules.

Step 3 — Generate PR Content

Title — Generate 3 options in the format [scope] description:

• Scope: determine from changed files — run sh scripts/discover-domains.sh to get the current domain list, then pick the one matching the changes. Use [global] / [ci/cd] for cross-cutting changes only. Wrap in brackets: [auth], [student], etc.
• Description: Korean, concise, no emojis, max 50 characters total
• Wrap class names, method names, annotations, and technical terms in backticks (e.g., @Transactional, StudentServiceImpl)

Body — Follow the .github/PULL_REQUEST_TEMPLATE.md structure:

• Korean 합쇼체: ~하였습니다, ~되었습니다, ~추가하였습니다
• No emojis
• Max 2500 characters
• Wrap all proper nouns and technical identifiers in backticks: class names, method names, annotations, file names, field names, config keys, module names

Step 4 — Write Body & Show Preview

Write the body to PR_BODY.md, then display:

## PR 제목 후보
1. [title1]
2. [title2]
3. [title3]

## 선택된 라벨
- label1, label2

## PR 본문 미리보기
[body content]

Ask the user which title to use (present options 1/2/3). Wait for the answer before proceeding.

Step 5 — Create PR

Run the creation script with the confirmed title and labels:

bash scripts/create-pr.sh "<confirmed-title>" "PR_BODY.md" "<label1>,<label2>"

After creation, display the PR URL. Cleanup: remove PR_BODY.md.
