The source didn't share its exact prompt, so we wrote this from what it describes.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Change my old X handle to my new one everywhere it appears on my Product Hunt launches and comments.

Check with me first: What are the old and new handles?

What I'll give you:
- My old and new X handles
- Access to my Product Hunt account (I'll log in myself)

Rules:
- Go through every launch and comment and replace the old handle with the new one.
- Change only the handle. Leave the rest of the text as it is.
- If something is missing or unclear, ask me instead of guessing.
- Stop when you're done and hand back a list of what you updated.

Output: A list of launches and comments updated, plus any you couldn't change.

You'll know it worked when: no launch or comment still shows the old handle.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Replace my old X handle with my new one on every Product Hunt launch and comment.

Quick check first: tell me if anything below is missing or unclear.

Inputs (fill in or confirm):
- Old and new X handles
- Product Hunt account (I'll log in)
- Launches/comments to skip

Rules:
- First list every launch, maker profile field and comment containing the old handle, with links.
- Edit only the handle; keep all other text identical.
- Check edited links point to the new handle's profile.
- Log each change with before/after text.
- Include the page link in each log line.

Checkpoint: Show me the list before editing anything.

If you get stuck: If a comment can't be edited (too old or locked), log it and move on. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Search Product Hunt for the old handle again after editing.

Output: Change log with links and anything not editable.

Done when: the old handle no longer appears on my Product Hunt content.
