"Paste this token to try the export: sk-live-secret." That sentence was not in the notes. Ade, a developer, still almost sent it, because it sounded helpful. The change lets admins export a CSV. Members see nothing new. Ade has a test path and a pasted token he must remove first.
After this guide you will be able to explain pull request description AI in your own words, copy a prompt that fits the job, and catch the extra sentence before anyone else sees it.
What Is Pull Request Description AI?
pull request description AI means using an AI tool to describe a change a reviewer can test, while a person checks every factual line against a source.
It is not a magic phrase you drop into a chat. It is a short method: one job, one source, one shape, one ban, and one human send. Ade, a developer, is a clear picture of the method. You already have this in the source: admin CSV export, no member button, and a test path with the token removed. The draft is only useful if it stays inside that.
This matters now because the tools are easy to open and the extra sentence is easy to miss. A beginner can produce a page that sounds finished. Sound is not the same as truth. If you remember one definition, remember this: a good draft is one you can point at.
Why Pull Request Description AI Matters
- You start from something true. You already have this in the source: admin CSV export, no member button, and a test path with the token removed. The guide keeps the draft tied to that, instead of asking the tool to invent a better story.
- You can see the mistake. The mistake in this story is easy to quote: "Paste this token to try the export: sk-live-secret." Once you can quote it, you can delete it. Vague worry is harder to edit.
- You get a prompt you can reuse. The prompt below is written for this job. Next time you change the notes, not the rules.
- A person still owns the send. Do not include secrets, tokens, or host names. The tool can draft. It cannot be the name on the email, the post, the file, or the decision.
People searching for write a PR description or GitHub Copilot pull request are usually stuck on the same gap. They have notes. They do not have a safe way to turn the notes into something they can send. The method below is that way.
How Pull Request Description AI Works
- Name one job before you name a tool. The job here is simple: describe a change a reviewer can test. pull request description AI starts after that sentence exists. Why it matters: A tool list feels like progress, but the blank page is still there.
- Show the source, then ask for a shape. The change lets admins export a CSV. Members see nothing new. Ade has a test path and a pasted token he must remove first. The shape is short enough that a colleague can check it quickly. Why it matters: The tool cannot be careful about a fact you never gave it.
- Hunt for one extra sentence. Delete "Paste this token to try the export: sk-live-secret." and read what remains. If the piece still does the job, that line was never needed. Why it matters: Most bad drafts are fine except for one confident addition.
Give this job 15 minutes. A longer chat feels thorough and often gets worse, because each reply adds another chance to invent.
Minutes 0 to 3. Open the source and nothing else. The change lets admins export a CSV. Members see nothing new. Ade has a test path and a pasted token he must remove first. Highlight admin CSV export, no member button, and a test path with the token removed. If that detail is missing, you are not ready to prompt.
Minutes 3 to 6. Paste a fenced prompt. The weak version is "Write a pull request and include everything from my clipboard." It asks for tone and forgets the fence. The strong version names the job, the source, the shape, and the ban.
Minutes 6 to 10. Read the draft once without fixing grammar. Hunt only for new claims. The claim that should not survive is "Paste this token to try the export: sk-live-secret."
Minutes 10 to 15. Cut that claim. Check that this remains true: The description has the test and the member line, and the token is gone. Then stop. More prompts after a clean draft usually sand it into something vague.
Reviewers need a path, not your clipboard. Ade's token line would publish a secret in a place that is hard to fully delete. Write the description from a human summary. If the summary is empty, ask the author for three sentences before any tool sees the diff. Diffs contain junk a customer note should never repeat.
A Prompt You Can Copy
Use this with GitHub Copilot. Replace the notes. Do not delete the ban.
Write a pull request description. What changed: admins can export CSV. What did not: members see no new button. Include the test path I paste. Remove tokens, passwords, and host names. Do not claim tests passed unless I said they passed.The weak prompt, for contrast, was: "Write a pull request and include everything from my clipboard." Keep the weak one in your head only as a warning. Do not paste it.
Best Tools for Pull Request Description AI
You do not need a large stack. Three tools cover the job. If you are choosing software for a whole company, start with the company buying shortlist after you can do this one task by hand.
GitHub Copilot
GitHub Copilot can draft the description beside the diff if you point it at the summary, not the secret.
Best for: a first draft when you already have the source
Price: GitHub Copilot Pro was about $10 a month on GitHub's plan page. Confirm before you buy.
How it helps: It turns the source into a draft of this job: describe a change a reviewer can test.
Good to know: Do not include secrets, tokens, or host names.
Cursor
Cursor does the same inside the editor.
Best for: a colder edit after the first draft
Price: Cursor lists a lower Plus plan and a higher Premium plan. Extra models can cost more. Confirm on Cursor's pricing page.
How it helps: It is good at listing lines that add a fact, including a line like "Paste this token to try the export: sk-live-secret."
Good to know: Do not include secrets, tokens, or host names.
Claude
Claude is a safe place to rewrite after you delete the token yourself.
Best for: a last pass in the tool that fits this file
Price: Claude Pro is about $20 a month on Anthropic's pricing page. Confirm before you buy.
How it helps: It is a safe place to rewrite after you delete the token yourself.
Good to know: Do not include secrets, tokens, or host names.
Step-by-Step: How to Get Started
Step 1: Write the job in one line
Write: describe a change a reviewer can test. Put that line above the chat. If you need a second sentence to explain the goal, you are mixing two tasks. Split them. pull request description AI works on one task at a time.
Step 2: Bound the source
The change lets admins export a CSV. Members see nothing new. Ade has a test path and a pasted token he must remove first. Copy only what you are allowed to share. Keep admin CSV export, no member button, and a test path with the token removed visible. Remove passwords, customer lists, health details, and legal files you do not have permission to upload.
Step 3: Use a prompt that draws a fence
Do not start with "Write a pull request and include everything from my clipboard." That prompt asks for a nice tone and leaves the facts open. Paste the prompt from the section above. Then replace the notes with yours.
Step 4: Keep only the version you can point at
Do not include secrets, tokens, or host names. Read every factual line and point at the source. The version you keep must pass this test: The description has the test and the member line, and the token is gone. You send it. The model does not.
When the same shape comes up every week, copy a workflow or a prompt template instead of starting from a blank chat. Change the source. Keep the ban.
Real Examples
Example 1: Ade
Situation: The change lets admins export a CSV. Members see nothing new. Ade has a test path and a pasted token he must remove first.
What to do: Use the prompt above. Tell the tool the job is to describe a change a reviewer can test. Reject any line like "Paste this token to try the export: sk-live-secret."
Why this works: Do not include secrets, tokens, or host names
Result: The description has the test and the member line, and the token is gone.
Example 2: A student
Situation: A class commit fixes a label.
What to do: The description says which screen changed.
Why this works: A pasted API key would leak in the class repo.
Result: The key never enters the text.
Example 3: An open-source maintainer
Situation: A bug fix needs steps and no internal URL.
What to do: They delete the staging host before they paste.
Why this works: Internal hosts do not belong in a public PR.
Result: Reviewers see steps only.
These are practice examples, not customer results. The test is the same in each one: if you cannot point at the source, it does not ship.
Common Mistakes to Avoid
- Opening with "Write a pull request and include everything from my clipboard.". The tool fills the silence with a confident extra claim. Do this instead: Name the job, the source, the length, and the ban in the same prompt.
- Leaving "Paste this token to try the export: sk-live-secret." because it sounds polite. Polite and untrue is still untrue. The reader may act on it. Do this instead: Delete it, even if the paragraph feels shorter.
- Pasting a whole inbox, folder, or database. You only need admin CSV export, no member button, and a test path with the token removed. Extra text gives the tool more chances to grab the wrong fact. Do this instead: Paste the smallest source that still contains the detail.
- Asking the tool to pick a plan, a price, or a legal conclusion. Those are decisions. A draft can list what the source says. It cannot make the decision for you. Do this instead: Write 'not in the source' and decide yourself, or ask the person who owns the decision.
Quick Comparison
| Option | Best for | Difficulty | Cost | Beginner tip |
|---|---|---|---|---|
| GitHub Copilot | First draft from a small source | Easy | Free plan, paid if you need more | Paste less than you think |
| Cursor | Second pass on a smooth draft | Easy | Check the vendor page | Ask it to mark new claims |
| Claude | is a safe place to rewrite after you delete the token yourself. | Easy | Check the vendor page | Do not move secrets into a personal login |
Tips That Actually Help
- Tip 1. Keep admin CSV export, no member button, and a test path with the token removed in the first three lines of the prompt so the model cannot skip it.
- Tip 2. Search the description for 'sk-', 'key', 'password', and 'token' before you press open.
- Tip 3. If the draft uses a number, a date, or a name, find it in the source before you keep it. "Paste this token to try the export: sk-live-secret." fails that test.
- Tip 4. Run the same notes through Cursor only after the first draft exists. A second tool is an editor, not a new source of facts.
- Tip 5. Save the prompt in your notes or in the prompt library. Next week, swap the source and keep the ban: Do not include secrets, tokens, or host names.
FAQ
What is the practical way to do pull request description AI?
Start with one source. The change lets admins export a CSV. Members see nothing new. Ade has a test path and a pasted token he must remove first. Ask for a draft of this job: describe a change a reviewer can test. Then delete any line the source does not support. The line to practice on is "Paste this token to try the export: sk-live-secret." The version you keep should match this: The description has the test and the member line, and the token is gone.
Why did the draft say "Paste this token to try the export: sk-live-secret."?
Because the first prompt was too open. "Write a pull request and include everything from my clipboard." asks for a polished result and does not forbid new claims. The tool prefers a complete sound. Do not include secrets, tokens, or host names. Put that ban in the prompt, then check the draft yourself.
Which tool should I open first?
Open GitHub Copilot for the first shape. Open Cursor when the draft sounds sure and you want extra lines marked. Open Claude when the work should stay in that product or needs a different kind of pass. Confirm the live price before you buy.
What should never go into the prompt?
Do not include secrets, tokens, or host names. Also leave out passwords, payment data, private customer lists, and health or legal records you are not allowed to upload. If you would not email it to a stranger, do not paste it.
Is this useful for a complete beginner?
Yes. You only need an account and one real note. Ade, a developer is not an expert in the story. The skill is the check, not a secret setting. You can practice on a free plan, then pay only if a limit blocks a real task.
The Bottom Line
Pull Request Description AI is a small, strict way to describe a change a reviewer can test. Ade, a developer, almost sent "Paste this token to try the export: sk-live-secret." because the first prompt was vague. The fix was not a new subscription. The fix was a source, a ban, and a read-aloud.
Your next step is small. Open GitHub Copilot, paste the prompt, and use a note you already have. Keep the draft only if this is true: The description has the test and the member line, and the token is gone.
