Why your week should take 9 minutes to plan
Sunday-night planning usually looks like this: calendar open in one tab, to-do list in another, a vague sense of dread in a third. You shuffle blocks around for an hour, tell yourself Tuesday-you will cope, and go to bed knowing the plan is already fiction.
Here's the shift: stop building the plan and start vetoing one. When Claude can see your actual calendar — not a description of it, the real thing — it can draft your whole week around what's already booked. Your job changes from architect to editor. Drafting takes Claude a couple of minutes; vetoing takes you the rest of the nine.
😮💨 Sunday night, before
- An hour of dragging calendar blocks around
- Deep work goes wherever there's a gap left over
- Overcommitment discovered on Thursday, in tears
- Forgotten tasks surface as 9pm panic
😌 Sunday night, after
- One prompt, one coffee, a drafted week
- Deep work protected before anything else lands
- Overcommitment flagged before Monday starts
- You read the plan, move two things, done
This is my actual system
My week gets time-blocked, prioritised and briefed in about 9 minutes — Claude drafts it, I veto a couple of blocks, done. On its first run it also found two emails I'd completely forgotten about and booked time to fix them. That used to be my Sunday-night panic; now it's a line item.
The setup — 10 minutes, once
The prompt only works if Claude can see reality. Three things to set up, and the first is the one that matters most: connecting your Google Calendar. Connectors are basically handing Claude the keys to the house — it sees what's actually booked instead of guessing.
Connect Google Calendar
In Claude: Settings → Connectors → Google Calendar (if you use Cowork, it's the same connector). Two minutes, no code. Once it's on, Claude reads your real bookings — every existing commitment becomes something it plans around, not over.
Give it a priorities note
One simple doc or pasted list: your top 3 priorities this week, plus the tasks rattling around your head. It doesn't need to be tidy — a brain dump works. Claude sorts; you don't have to pre-organise the thing you're asking it to organise.
Set your personalisation rules
These are the "nothing before 9am" rules — earliest start, meeting-free days, when you film, when the school run happens. The prompt below asks for them on the first run, and Claude remembers them for every week after. You only teach it once.
Why the calendar connection is non-negotiable
Without it, Claude plans a fantasy week for a fantasy person with zero appointments. With it, every suggestion has to fit around your dentist, your client calls and school pickup. That's the difference between "productivity advice" and a plan you can actually follow on Tuesday.
The week-planner prompt
This is the whole magnet, so it earns its length. It's built ask-first: before planning anything, Claude checks your rules — so the first run teaches it your preferences and every run after that just uses them. Copy it, paste it into Claude, attach or point it at your priorities note, and let it go.
The ask-first bit is the trick
Most planning prompts fail because Claude guesses your preferences and packs the week like you're a robot with no school run. Making it ask for your rules first — and remember your corrections — is what turns run one from "nice try" into run five being scarily accurate.
Make it weekly
One planned week is nice. The compounding starts when it's a ritual — because every correction you make teaches Claude your real preferences, and by week three or four the drafts barely need a veto. (And yes, the keyword was MULLET for a reason: this planner is all business up front so the weekend out back stays yours.)
The Sunday ritual — 9 minutes, start to finish
1. Update the priorities note
Two minutes of brain dump: what matters this week, what's due, what's nagging at you. Messy is fine.
2. Run the prompt
Paste the week-planner prompt (or just say "plan my week" once Claude knows the drill). It reads the calendar and drafts.
3. Veto, don't rebuild
Read the plan and the "what I moved and why" note. Move a block or two. Resist the urge to redo it by hand — that's the old job.
4. Correct out loud
Anything that grates — "nothing before 9am", "no calls on Fridays" — say it once. It becomes a permanent rule, not a weekly nag.
Sunday evening or Monday morning, whichever suits — the point is same time, every week, so the corrections compound instead of resetting.
Level up: the set-and-forget version in Cowork
If you use Claude's Cowork, turn the ritual into a scheduled task: "Every Sunday at 4pm, read my calendar and priorities note, draft my week using my planning rules, and have it waiting for me." Then Monday morning isn't "run the prompt" — it's "open the plan that's already sitting there". The planner plans itself.
Setup checklist
Everything you need — and everything you don't. If the left column is sorted, you can run your first plan today.
The honest caveat
Claude plans the week — you still have to live it. This kills the hour of Sunday shuffling, the forgotten tasks and the Thursday overwhelm ambush. It doesn't do the deep work for you. That part stays gloriously, annoyingly yours.
