Build Your Own AI Chief of Staff with OpenClaw: The Smart Calendar Brief

You know that sinking feeling right before an important meeting? The one where you realize you have no idea who you're talking to, what their company does, or why this meeting is even on your calendar?

I see this pain point everywhere in the research. FlyLoop, a startup building "AI Agent for Scheduling," hit the front page of Hacker News last week with 19 upvotes and active discussion. The non-intrusive email automation tool mxtoai scored 44 points. The signal is clear: people want AI that handles the cognitive overhead of meeting preparation without changing how they work.

Today, I'm sharing a free OpenClaw skill that gives you exactly that.

The Problem: Calendar Blindness

Most knowledge workers face a daily parade of meetings with insufficient context. You might spend 15-20 minutes before each external meeting researching attendees on LinkedIn, checking Crunchbase for funding news, and scanning their company blog for recent announcements.

But let's be honest: you don't do that. Nobody does. We wing it.

The result? Missed opportunities, awkward small talk, and the nagging feeling that you could have closed that deal or built that relationship if you'd just been better prepared.

The Skill: Calendar Brief

The Calendar Brief skill is your AI Chief of Staff. It runs automatically each morning (or 15 minutes before each meeting), reads your calendar, researches attendees, and delivers a concise intelligence brief.

Here's what a typical brief looks like:

📅 MEETING BRIEF: Q1 Review with Acme Corp
⏰ Today, 2:00 PM - 3:00 PM (Zoom)

🎯 PURPOSE
Quarterly business review — expect questions about usage metrics and renewal timeline.

👥 ATTENDEES
• Sarah Chen (CEO, Acme Corp)
  - Previously VP Product at TechCorp (2018-2022)
  - Harvard MBA, Stanford CS
  - Recent: Acme raised $12M Series B in Jan 2026
  - Speaking at SaaStr next month

• Mike Rodriguez (CTO)
  - Joined Acme 2024 from Google Cloud
  - Focus areas: AI integration, platform scalability

🏢 ACME CORP CONTEXT
- Founded: 2021, $28M total funding
- Employees: ~45 (hiring for 12 roles)
- Recent news: Launched AI feature suite last week

💡 TALKING POINTS
• Congratulate on recent funding
• Reference their new AI features — tie to our roadmap
• Ask about their scaling challenges

How to Use It

1. Install the Skill

cd ~/.openclaw/skills
git clone https://github.com/thenatechambers/openclaw-skills-repo.git cortex-skills
cp -r cortex-skills/skills/calendar-brief ./calendar-brief

2. Configure Your Calendar

Copy the example config and add your calendar source:

cp calendar-brief/config.example.json calendar-brief/config.json

For Google Calendar, you'll need OAuth2 credentials. For any calendar, you can use a secret ICS URL:

{
  "calendar_type": "ics",
  "ics_url": "https://calendar.google.com/calendar/ical/.../basic.ics"
}

3. Set Where Briefs Are Delivered

Edit config.json to choose your output channels:

{
  "output": {
    "slack": { "enabled": true, "channel": "#meeting-prep" },
    "email": { "enabled": true, "to": "you@example.com" },
    "file": { "enabled": true, "path": "~/meeting-briefs/" }
  }
}

4. Schedule It

Add to your OpenClaw crontab:

# Run at 8 AM every weekday
0 8 * * 1-5 cortex skill calendar-brief --today

Or run it manually before a specific meeting:

cortex skill calendar-brief --next

The Recommendation

Use structured JSON output from your LLM, not free-form text generation.

The magic of this skill isn't the research — it's the synthesis. Most people try to build calendar assistants that dump raw calendar data or generate walls of text. The Calendar Brief skill works because it structures the output:

1. Purpose first — The "why" of the meeting, extracted from the description
2. Attendees with context — Not just names, but backgrounds and relevance
3. Company intelligence — Funding, headcount, recent news
4. Actionable talking points — Suggestions based on the research, not generic prompts

This structure matters because it matches how your brain processes information before a meeting. You don't want a paragraph about Sarah Chen. You want to know she's the decision-maker, she just raised money, and she cares about AI integration.

Why This Approach Beats Alternatives

• Calendar apps give you notifications, not intelligence
• CRM tools have data but require manual entry and don't surface it proactively
• AI chatbots can research but don't connect to your actual calendar automatically

The OpenClaw approach wins because it combines:

1. Integration — Direct calendar access
2. Automation — Runs on your schedule without prompting
3. Intelligence — Structured research + synthesis
4. Delivery — Sends where you already work (Slack, email, etc.)

Why This Matters for Cortex Users

This skill exemplifies what Cortex enables: AI agents that anyone can deploy and use without engineering teams. You don't need to build a calendar integration, set up a research pipeline, or maintain infrastructure. You install the skill, configure three settings, and your AI Chief of Staff starts working.

The broader pattern here is ambient intelligence — AI that watches your workflows and adds value without requiring you to change behavior. You still use your regular calendar. You still get your notifications the same way. But now you walk into every meeting prepared.

That's the promise of agent infrastructure for non-technical teams. And that's what we're building with Cortex.
