A prompt is the message you send to the AI tool. Copy the one on this page, put your own details where it asks, and read the answer before you act on it.

Prompt

Recreated prompt

The source didn't share its exact prompt, so we wrote one from what it describes. The result shown is the source's, not ours.

What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

Using my Claude Code MCPs with read/write but no delete on Reminders, read the shared Grocery list, detect items I usually buy every week, and add any missing staples without duplicating what I already added with Siri. Do not delete anything.

Try this in:

ChatGPT Gemini Grok Claude

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

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

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Top up a shared grocery Reminders list with usual weekly staples only.

Questions to ask me first:
- What is the Reminders list name?
- Which items count as weekly staples?
- Confirm no-delete MCP permissions?

Inputs (fill in or confirm):
- List: [GROCERY]
- Staples history: [PRIOR WEEKS]
- Permissions: [READ/WRITE NO DELETE]

Rules:
- Never delete or clear the list.
- Skip items already present.
- Prefer staples actually bought most weeks.

Checkpoint: Show the proposed adds and wait for OK.

If you get stuck: If MCP access fails, output the proposed adds as text.

Verify before you finish: No duplicates and no deletions occurred.

Output: Updated shared list plus add summary.

Done when: My spouse and I share a primed grocery list.

Outcome

HN commenter bronco21016 used Claude Code to build read/write MCPs (no delete) for Apple apps. One workflow reads a shared iCloud “Grocery” Reminders list, finds items commonly bought every week, and pre-populates the list without duplicating anything already added via Siri during the week—keeping a spouse-shared list current as a starting point.

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.
