Optimize a 50/50 parenting-time calendar with Claude Code

WorkedEvidence: Described by posterPosted Last checked

bronco21016 uses Claude Code MCPs with OR-Tools to propose and write a 50/50 parenting-time calendar each month.

How to use this

  1. Tap Copy prompt.
  2. Open the tool the case used (or a similar one) and paste the prompt; results may differ from the original.
  3. Paste it into the message box.
  4. Send it, then read the answer before acting on it.
New to this? What's a prompt?

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.

Fetch this month’s calendar events and parenting-plan emails via my Claude Code MCPs. Structure constraints and requests as JSON for my OR-Tools parenting-time optimizer. Show a few 50/50 candidate calendars. After I pick one, write those events back with read/write MCP access—no deletes.

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.

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

These links are only a shortcut. We're not affiliated with OpenAI, Google, Anthropic or xAI, and your results may not match the source.

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: Propose balanced parenting-time calendars from real schedules and write the chosen one back.

Questions to ask me first:
- What are hard constraints and soft requests this month?
- Where is the optimizer script?
- Which calendar gets the final events?

Inputs (fill in or confirm):
- Constraints: [WORK SHIFTS / REQUESTS]
- Optimizer: [OR-TOOLS SCRIPT]
- Calendar: [NAME]
- Permissions: [NO DELETE]

Rules:
- Honor hard constraints before balance.
- Present multiple candidates; I choose.
- Never delete existing events.

Checkpoint: Show candidate summaries before writing any events.

If you get stuck: If email context is missing, ask for a pasted constraint list.

Verify before you finish: Chosen plan meets hard constraints and roughly 50/50 time.

Output: Candidate plans plus written calendar events for the pick.

Done when: The month’s parenting calendar is set without a manual rebuild.

Claude Code

Outcome

The same bronco21016 setup feeds calendar events and planning emails into an OR-Tools optimizer Claude Code optimizes each month. Inconsistent work schedules for both parents become JSON inputs; the optimizer returns a few candidate 50/50 parenting-time calendars honoring requests and hard constraints; bronco reviews and has Claude Code write the chosen solution back through the MCP.

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