Build Your Own AI Chief of Staff

A Chief of Staff makes sure the CEO's priorities actually happen.

What if your AI could do that?

In 30 minutes you'll build an agent that manages your calendar, triages your inbox, tracks your tasks, and keeps you focused on what matters.

This is the most practical course in the series.

Chapter 1: "The Overwhelm" — Why you need a Chief of Staff

You have 47 unread emails. 3 meetings today. A Slack channel blowing up. A todo list from last week you haven't looked at. And someone just texted asking if you're free for coffee.

0:00

Your Morning

Try to manually triage these notifications. Click each one to handle it:

A human Chief of Staff would: scan the emails (flag 3 urgent, archive 30 junk, draft replies to 5), prep you for your meetings (pull context from past conversations), prioritize your todo list (what actually moves the needle today), and reply to the coffee text with your availability.

The role of an AI CoS:

  • Triage — scan inputs, prioritize, surface what matters
  • Context — remember everything, pull relevant history
  • Draft — write responses you can approve with one tap
  • Schedule — manage calendar, find meeting times, prep briefs
  • Track — maintain task lists, follow up on commitments, remind you

Chapter 2: "The Integrations" — Connecting to your life

An AI CoS is only useful if it can see your stuff. The integration layer:

Integration Map

Drag each integration onto the central hub to connect it:

Agent
📧
Gmail
Read, search, send emails
📅
Calendar
Read events, create meetings
💬
Slack
Read, send messages
Tasks
Manage todo lists
📁
Files
Read, search documents
🌤
Weather
Current conditions

Each integration is just a set of tools the agent can call.

Under the Hood

How a Gmail integration works:

const tools = [{
  name: 'gmail_search',
  description: 'Search emails by query',
  parameters: { 
    query: 'string', 
    maxResults: 'number' 
  }
}, {
  name: 'gmail_send',
  description: 'Send an email',
  parameters: { 
    to: 'string', 
    subject: 'string', 
    body: 'string' 
  }
}];

The agent doesn't need special access. It uses the same APIs you would. Gmail API, Google Calendar API, Slack API — they're all documented, standard REST endpoints. The agent calls them with your credentials.

Chapter 3: "The Morning Brief" — Building the daily routine

The killer feature: every morning your agent scans everything and gives you a brief.

Build Your Morning Brief

Configure what your agent checks at 6 AM every day:

📅 Today's calendar events
📧 Urgent emails (VIPs + flagged)
✅ Overdue tasks
🌤 Weather (do you need an umbrella?)
📰 News headlines
📊 Yesterday's metrics

Your agent runs this at 6 AM every day while you're still asleep.

The Heartbeat Pattern

// Every morning at 6 AM
schedule('0 6 * * *', async () => {
  const calendar = await getCalendarEvents(today);
  const urgentEmails = await searchEmails('is:unread label:important');
  const overdueTasks = await getTasks({ status: 'overdue' });
  const weather = await getWeather(userLocation);
  
  const brief = composeBrief({ 
    calendar, 
    urgentEmails, 
    overdueTasks, 
    weather 
  });
  
  await sendMessage(userChannel, brief);
});

Proactive agents are just scheduled prompts with tool access. The "magic" is in the prompt that decides what's worth surfacing and what to ignore.

Chapter 4: "The Triage Engine" — Teaching it your priorities

Not all emails are equal. Not all Slack messages need a response. The agent needs to learn YOUR priorities.

Train Your Triage

Drag each notification to the appropriate tier:

Tier 1

Interrupt me

Tier 2

Surface in brief

Tier 3

Handle silently

📧 Email from your CEO: "Need Q4 numbers ASAP"
📧 Amazon: "Your order has shipped"
💬 Slack from teammate: "Great job on the presentation!"
📧 LinkedIn: "You have 5 profile views"
📅 Calendar: "Meeting with investors in 30 minutes"
📧 Newsletter: "10 AI tools you should know"
📧 Bank: "Your statement is ready"
💬 Slack: "Anyone know where the printer paper is?"

The System Prompt

You are my Chief of Staff. Triage incoming messages:

TIER 1 (notify immediately):
- From: [list of VIPs]
- Contains: "urgent", "asap", "deadline"
- Calendar conflicts

TIER 2 (include in daily brief):
- Newsletters from: [list]
- Task updates
- Non-urgent emails from known contacts

TIER 3 (handle silently):
- Marketing emails → archive
- Scheduling requests → auto-reply with calendar link
- Receipts → label and archive

The priority system is just a well-written system prompt plus rules. You don't need ML or custom models. You need clear instructions and good tool definitions.

Chapter 5: "The Trust Boundary" — What the agent does vs what it drafts

The critical question: what should your agent DO vs what should it DRAFT FOR YOUR APPROVAL?

Autonomy Slider

Set the autonomy level for each type of action:

📧 Archive junk email
📧 Reply to important email
📅 Schedule internal meeting
🐦 Post on social media
💰 Approve expense report
📄 Share confidential document

Approval Inbox

Your agent has drafted these actions. Review and approve:

📧 Email Reply
To: sarah@company.com
Subject: Re: Q4 Budget Review
"Hi Sarah, I've reviewed the budget proposal. The marketing allocation looks reasonable, but I'd like to discuss the R&D increase before finalizing. Can we schedule 30 minutes this week? Best regards..."
📅 Meeting Request
With: john@company.com, alice@company.com
Topic: Sprint Planning
"Thursday 2 PM - 3 PM (based on everyone's availability). Conference Room B is booked. I'll send the agenda tomorrow."
💬 Slack Reply
Channel: #general
Reply to: "Who's joining the team lunch?"
"I'll be there! Looking forward to the new sushi place. Should we make a reservation for 6 people?"

The Implementation

async function handleEmail(email) {
  const priority = await triageEmail(email);
  
  if (priority.tier === 3) {
    await autoHandle(email); // Archive, label, etc.
    return;
  }
  
  const draft = await generateReply(email);
  
  if (priority.tier === 1) {
    await sendForApproval(draft, { 
      channel: 'slack', 
      urgent: true 
    });
  } else {
    await queueForBrief(draft);
  }
}

The best AI Chief of Staff isn't fully autonomous. It's an extension of your judgment with infinite patience. It drafts 50 emails while you approve the 5 that matter.

Your AI Chief of Staff is Ready

A Chief of Staff doesn't replace you. They amplify you.

Your AI CoS handles the 80% that's routine so you can focus on the 20% that needs your brain. And it never takes a day off.

You've built an agent that:

  • 🔍 Triages your communications intelligently
  • 📋 Briefs you every morning with what matters
  • ✍️ Drafts responses for your approval
  • 📅 Manages your calendar and commitments
  • 🔒 Respects your trust boundaries

This isn't theory. People are building exactly this with OpenClaw, AutoGPT, and custom agent frameworks. The patterns you learned today scale from personal productivity to enterprise operations.

The question isn't whether AI can be your Chief of Staff.

You just designed one.

The question is when you'll deploy it.
