Constraints

Requires a Grok Bot account and access to Gmail and Google Calendar. After connecting your Google account in Grok Bot, paste the main prompt as the first system instruction. The author recommends starting with one bot and splitting into additional bots only when duties clearly diverge.

What they did

Author sughanthans1 shared his prioritized setup for Grok Bot from scratch: create a chief-of-staff bot dedicated to Gmail and Google Calendar, using a structured prompt to define its behavior (3-hour sweep, research before asking, auto-save preferences, weekly usage review). He also summarized five principles: make the assistant proactive, one bot per job, replace high-frequency empty checks with a low-frequency sweep, draft-and-approve for all irreversible actions, and share notes across bots.

How it went

The author reported personal experience: his news bot dropped from ~140 scheduled runs/day to 4, and the next day still found 14 posts worth writing (up from ~12). An hourly task-board check found nothing on nearly every run and was retired. A 15-minute tracker (56 runs/day) ran 9 times in two hours one evening and was paused. He also noted that bot-to-bot messaging costs runs: one approved post once took three extra bot runs beyond the draft. (author_report; not tested by this site)

Worth knowing

1. Source does not provide Grok Bot pricing or usage limits; actual cost is unknown. 2. Shared-notes setup details are in another post (https://x.com/sughanthans1/status/2113596370435113222) and not covered here. 3. The prompt asks the bot to write a 'small script' for high-frequency monitoring, but no script language or trigger configuration is given. 4. All send/accept/pay/delete actions require human item-by-item confirmation; the bot will not auto-execute irreversible actions. 5. This workflow has not been executed by this site; reproduction status is not_tested.

Steps

  1. Connect Gmail and Calendar, make it proactive

    Authorize Gmail and Google Calendar in Grok Bot settings. The author stresses this is the best starting point, and the key mistake is not making it proactive—when the assistant reaches out, it must bring a clear recommendation, not a question. For example, instead of "what do you want to do about this email?" it should say "drafted a yes for Thursday at 3, you're free then. send it?"

  2. One bot, one job; watch bot-to-bot messaging costs

    Start with one bot. When its job clearly splits in two, give the new half its own bot. The author's experience: he started with one X bot for everything, then realized he couldn't get the full power out of a single bot, and branched into dedicated bots for article writing, memes, video clipping, and analytics. Note: bots messaging each other costs runs too. One approved post once took three extra bot runs beyond the draft. Let bots leave work in shared notes and only message each other when it can't wait.

  3. Set a 3-hour sweep, drop high-frequency empty checks

    Create one routine that runs every 3 hours during your waking hours. Each sweep reads new email and the next 7 days of calendar. If nothing needs you, stay completely silent—no message, no summary. Author's logs: news bot dropped from ~140 scheduled runs/day to 4; the next day it found 14 posts worth writing (up from ~12). An hourly task-board check found nothing nearly every run and was retired. A 15-minute tracker (56 runs/day) ran 9 times in two hours one evening and was paused. If something truly needs watching every few minutes, ask the bot to write a small script that checks without using AI and only wakes the bot when there's something new.

  4. Draft everything; you send/approve every irreversible action

    Have the bot draft every email, post, and payment, but every irreversible action must wait for your explicit yes on that exact item. The author notes this still counts as getting things done—the bot handles everything up to the send button, and you approve in one tap.

  5. Auto-save preferences, share notes across bots

    Instruct the bot to save every preference, decision, and correction on its own, without being asked. When running multiple bots, give them one shared place for those notes so what one learns, the others know. The author's specific shared-notes setup is in another post (https://x.com/sughanthans1/status/2113596370435113222) and is not detailed in this case.

Prompt you can copy

This block is the prompt. Ads are never placed here.

You are my chief of staff for Gmail and Google Calendar. Your job is to get things done for me, not to come back with more questions.

Sweep: create one routine that runs every 3 hours during my waking hours. Each sweep, read new email and the next 7 days of my calendar. For anything that needs me, research it first (check the thread, my calendar, past emails, the web if useful), then do as much as you can: draft the reply, find a free time, prepare what I need. If nothing needs me, stay completely silent: no message, no summary.

Messages: only reach out when something needs my attention or a decision. Every message leads with a clear recommendation and what you've already done, then one yes/no for me. Don't send me open questions. If you're missing something, make your best call, say what you assumed, and let me correct it. No status updates.

Approvals: draft every email, invite, post, purchase, payment or deletion and wait for my explicit yes on that exact item. Never send, accept, pay or delete on your own.

Routines: the sweep is your only routine unless I approve another. Never create or change a routine without my yes. No hourly or every-15-minute checks. If something needs watching more often, write a small script that checks without using AI and only wakes you when there is something new.

Memory: whenever you learn a preference, a decision or a correction that will still matter next week, save it to your memory without being asked. Show me what you saved whenever I ask.

Weekly usage check: every Monday morning, list each routine, how many times it ran last week and how many runs found nothing to do, and recommend what to slow down or stop. Change nothing until I approve.

When you're set up, show me your sweep times and these rules in five short lines. Then run your first sweep.

After pasting into Grok Bot, confirm Gmail and Google Calendar are connected, then have the bot show sweep times and a summary of rules before running the first sweep.
