Prompt Recreated prompt

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: Rename my train ticket files so each name shows the travel date and destination.

Check with me first: What naming style do I want, for example 2026-09-28 London?

What I'll give you:
- The folder with my ticket files

Rules:
- Read each ticket and rename the file with its date and destination.
- If a ticket is unclear, leave it and tell me.
- Don't delete anything.

Output: The renamed files plus a list of any you couldn't read.

If anything here is unclear or missing, ask me instead of guessing.

You'll know it worked when: I can find any ticket just by looking at the file names.

Try this in:

Sends the Recreated prompt shown above. ChatGPT and Grok open with it filled in, and ChatGPT may send it straight away. Gemini opens empty, so we copy the prompt for you to paste. Every button also copies it.

The source used Claude Cowork, which can take actions in a browser or app. These are general chat tools, so results may differ, and a normal chat may only give you a plan.

Opens in a new tab. We don't see what you send.

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

Goal: Rename my train ticket files so each name shows travel date and destination.

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

Inputs (fill in or confirm):
- Ticket folder
- Naming style (e.g. 2026-09-28 London)
- How to handle return tickets
- Language for destination names

Rules:
- Read the travel date (not booking date) and destination from each ticket.
- Rename as YYYY-MM-DD Destination; add -2 for duplicates.
- Keep extensions.
- Log old → new names.
- Use the destination station's common city name (e.g. 'London' not 'London Kings Cross') unless I ask otherwise.
- For returns, use the outbound date and add 'return'.
- Show me the rename plan before renaming.

Checkpoint: Show the rename table before renaming.

If you get stuck: If unclear, list the file for me. 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: Count files before and after.

Output: Rename log.

Done when: every ticket name shows date and destination.

  • Rename, organize and de-duplicate files with Claude CodeRecreated promptEvidence: Described by poster

    Claude Code organized and renamed the poster's files and folders and found and removed duplicates; the poster says it worked incredibly well.

  • After the poster scanned almost 200 invoices, Claude Cowork split them out, renamed them, sorted them into folders and created a summary Excel file.

  • Nick Davidov asked Claude Cowork to organise their spouse's desktop. It asked permission to delete temporary Office files, they agreed, and then it said "ooops": while renaming, it had deleted a folder with every photo the spouse had taken on their camera over 15 years. The deletion was done in the terminal, so nothing was in the Trash; iCloud had already synced the new structure, there was no Time Machine backup, and disk recovery tools found nothing. Apple pointed them to iCloud's recovery feature, which keeps removed iCloud Drive files for 30 days, and the photos started coming back. Their advice: don't let these tools near anything hard to repair or not under version control.
