What PR Description Generator does, with a checked example

This tool builds a pull request description in the four-section shape reviewers expect: a summary, a bulleted list of changes, how the change was tested, and screenshots. You fill in each field and it returns a ready-to-paste Markdown block with consistent heading levels and formatting. The thing most people get wrong is expecting the tool to write the content for them. It organizes and formats what you enter; it does not read your branch, diff, or commit history, and the description contains only your own words. The value is structure and completeness, not generation.

Worked example

A concrete input and expected output from the current implementation.

Input

Title: Add dark mode toggle
Summary: Adds a theme toggle to the header. The choice persists in localStorage and the saved theme is applied on page load.
Changes (one per line):
- Add the toggle button to the header
- Persist the choice in localStorage
- Apply the saved theme on page load
Testing: Verified the toggle in Chrome and Safari, reloaded the page to confirm persistence, and tabbed through the header to check focus.
Screenshots: header-light.png (Header in light mode), header-dark.png (Header in dark mode)

Expected output

## Summary
Adds a theme toggle to the header. The choice persists in localStorage and the saved theme is applied on page load.

## Changes
- Add the toggle button to the header
- Persist the choice in localStorage
- Apply the saved theme on page load

## Testing
Verified the toggle in Chrome and Safari, reloaded the page to confirm persistence, and tabbed through the header to check focus.

## Screenshots
![Header in light mode](header-light.png)
![Header in dark mode](header-dark.png)

Every line of the output traces to a line of input. The tool wraps the entered content in its template headings, converts each changes line into a hyphen bullet, and turns each screenshot file name and caption into an image link.

How the result is produced

1

Template assembly

The form exposes one field per template section: a summary paragraph, a multiline changes list, a testing note, and screenshot entries with captions. On submit, your entries are merged into a Markdown document with section headings, each changes line becoming a hyphen bullet and each screenshot becoming an image line. Nothing is rewritten or reworded, so what you see in the output is exactly the content you supplied.

2

Plain-text Markdown output

The result is a self-contained Markdown block with no surrounding HTML or wrapper, so it pastes directly into the description box of GitHub, GitLab, or Bitbucket and renders with their standard Markdown support. The tool runs entirely in the browser and nothing you enter is uploaded, which matters here because a PR description can carry unreleased code details or screenshots of internal UI.

Good uses

  • Opening a PR on GitHub when your team expects summary, changes, and testing sections and you want a consistent starting point every time.
  • Filling in a description for a PR that was opened with only a title, working from your own notes before you ask for review.
  • Standardizing descriptions across a portfolio of small repos so every PR has the same headings and bullet format and reviewers can scan them quickly.

Limits and checks

  • The tool cannot see your branch, diff, or commit messages, so it cannot detect what you left out. A vague summary stays vague, and the description can be complete-looking while missing a real test plan.
  • Screenshot entries become image links to the file names you type. GitHub renders an image only when that file exists at that path in the branch or at a hosted URL, so local file paths you never push produce broken image icons.
  • The four headings are a generic convention, not your repository's pull_request_template.md. If your repo enforces additional required fields, such as a checklist or a Jira ticket link, you must add them yourself after pasting.

Common questions

Can it write the description from my branch or diff?

No. The tool works only from what you type into its fields. It does not fetch your repository, read commits, or inspect a diff, so it cannot summarize code it has never seen. If you want the description to reflect what actually changed, paste your own notes or the relevant commit messages into the summary and changes fields and let the tool structure them.

Will the pasted output render correctly in GitHub?

Yes, for standard Markdown: GitHub renders headings, bullet lists, and image syntax as written, so the block pastes straight into the PR description box. Two details to know: task lists written as - [ ] render as interactive checkboxes, and images referenced by file path display only after those files are pushed to the branch or otherwise reachable at the URL in the link.
