Generate PR Description

Generate a concise pull request description by analyzing git changes and using the project's PR template.

Language: Always generate PR titles and descriptions in English, regardless of the user's language or the language of commit messages.

Workflow

1. Identify parent branch

   • Current branch: git branch --show-current
   • Parent branch: default main; if absent, master (git show-ref --verify --quiet refs/heads/main || echo master)

2. Analyze changes

   • Get diff stats: git diff --stat <parent-branch>..HEAD
   • Get commit messages: git log --oneline <parent-branch>..HEAD
   • Get file changes: git diff --name-status <parent-branch>..HEAD
