Generate PR Description

Instructions

When this skill is activated, follow these steps strictly:

1. Get the Diff:

   • Run git diff main...HEAD to identify changes in the current branch relative to the main branch.
   • If the user specifies a different base branch, use that instead of main.

2. Generate Content (Strictly English):

   • Create a PR description in English with the following sections:
     • Summary: A high-level overview of the purpose of this PR.
     • Changes: A detailed bulleted list of technical changes.
     • Test: A description of how these changes were verified.

3. Output to File:

   • Do NOT use any tools to actually create or push a PR to GitHub/GitLab.
   • Save the generated content into a file named PR_DESCRIPTION.md in the root directory of the current project.
   • If the file already exists, overwrite it.

4. Completion:

   • Inform the user: "PR description has been generated and saved to PR_DESCRIPTION.md."
   • Provide a brief summary of what was written in the terminal for immediate feedback.

Examples

• "Generate a PR description for my current changes."
• "幫我寫 PR description 並存成檔案。"
