name: ms-graph-calendar description: Find available meeting times and free/busy slots for company employees using Microsoft Graph API. Use when user asks to schedule a meeting, find a free slot, check when employees are available, or look up someone's calendar availability. version: 1.0.0 metadata: {"openclaw": {"emoji": "📅", "requires": {"env": ["AZURE_TENANT_ID", "AZURE_CLIENT_ID", "AZURE_CLIENT_SECRET"], "bins": ["node", "curl"]}, "primaryEnv": "AZURE_CLIENT_SECRET"}}

Microsoft Graph Calendar — Find Free Slots

Use this skill when the user wants to:

• Find a time when multiple employees are all free
• Check if a specific person is available at a given time
• List upcoming meetings / busy blocks for one or more people
• Suggest meeting slots across the company

Setup (ทำครั้งแรกครั้งเดียว)

ถ้าผู้ใช้ยังไม่เคย setup หรือระบบแจ้งว่าขาด credentials ให้ทำดังนี้:

1. ถามผู้ใช้ 3 ค่านี้ทีละค่า:

   • AZURE_TENANT_ID (Azure Portal → Azure Active Directory → Overview)
   • AZURE_CLIENT_ID (App registrations → your app → Application (client) ID)
   • AZURE_CLIENT_SECRET (App registrations → your app → Certificates & secrets)

2. เมื่อได้ครบแล้ว รันคำสั่ง:

node skills/ms-graph-calendar/scripts/setup.js \
  --tenant-id <AZURE_TENANT_ID> \
  --client-id <AZURE_CLIENT_ID> \
  --client-secret <AZURE_CLIENT_SECRET>

ค่าจะถูกบันทึกไว้ที่ ~/.openclaw/ms-graph-calendar.json (permission 600) และจะถูกโหลดอัตโนมัติทุกครั้งที่ใช้ skill

3. ทดสอบด้วย:

node skills/ms-graph-calendar/scripts/get-token.js

ถ้าได้ "✅ Token acquired" แปลว่าพร้อมใช้งานแล้ว

App Registration ต้องมี Application Permissions:

• Calendars.Read — read all users' calendars
• User.Read.All — list employees
• Admin ต้อง Grant consent ก่อน

---

Configuration

Authentication is cached after first login. No environment variables required for device code flow.

For headless/automated operation, set these environment variables:

• AZURE_CLIENT_ID - Azure AD app client ID
• AZURE_CLIENT_SECRET - Azure AD app secret
• AZURE_TENANT_ID - Tenant ID (use "consumers" for personal accounts)

---

Tools

This skill runs Node.js scripts via bash. Files:

• scripts/ — Node.js scripts
• nicknames.md — ตาราง mapping ชื่อเล่น → email (แก้ไขได้เลย)

---

Instructions

Step 1 — Get Access Token

Before any Graph API call, get an app-only token:

node skills/ms-graph-calendar/scripts/get-token.js

Store the token in a temp variable for subsequent calls.

Step 2 — Parse the User's Request

Extract from the user's message:

• Who: names or emails of attendees (e.g. "Alice and Bob", "the marketing team")
• When: date range to search (e.g. "this week", "next Monday", "March 5–7")
• Duration: how long the meeting should be (default 60 minutes)
• Timezone: default to Asia/Bangkok if not specified

If any info is missing, ask the user before proceeding.

Step 3 — Resolve Employee Emails

3a. ลองแปลงชื่อเล่นก่อน (เร็วกว่า ไม่ต้องเรียก API):

node skills/ms-graph-calendar/scripts/resolve-nicknames.js --names "แบงค์,มิ้ว,โบ้"

อ่านจาก nicknames.md ในโฟลเดอร์ skill — แก้ไขได้ตรงนั้นเลย

3b. ถ้าหาไม่เจอใน nicknames.md ให้ fallback ไปค้น Graph API:

node skills/ms-graph-calendar/scripts/list-users.js --search "ชื่อ"

Confirm กับ user ถ้ามีคนชื่อเดียวกันหลายคน

Step 4 — Find Free Slots (choose one method)

Method A — findMeetingTimes (best for small groups, ≤10 people):

node skills/ms-graph-calendar/scripts/find-meeting-times.js \
  --attendees "alice@company.com,bob@company.com" \
  --start "2025-03-01T08:00:00" \
  --end "2025-03-01T18:00:00" \
  --duration 60 \
  --timezone "Asia/Bangkok" \
  --max 5

Method B — getSchedule (best for large groups or viewing free/busy blocks):

node skills/ms-graph-calendar/scripts/get-schedule.js \
  --emails "alice@company.com,bob@company.com,carol@company.com" \
  --start "2025-03-01T00:00:00" \
  --end "2025-03-07T00:00:00" \
  --timezone "Asia/Bangkok" \
  --interval 30

Step 5 — Present Results

Format the available slots clearly:

📅 Available slots where everyone is free:

1. Monday 3 Mar · 10:00–11:00
2. Tuesday 4 Mar · 14:00–15:00
3. Wednesday 5 Mar · 09:00–10:00

Which slot works best?

If no slots are found, widen the search window and try again, or report that no common availability exists in that period.

Example Conversations

User: "Find a 1-hour slot this week where Alice, Bob, and Carol are all free" Agent:

1. Resolves emails for Alice, Bob, Carol
2. Runs find-meeting-times.js with date range = this Mon–Fri
3. Returns top 3 available slots

User: "Is John free tomorrow afternoon?" Agent:

1. Resolves John's email
2. Runs get-schedule.js for tomorrow 12:00–18:00
3. Reports free/busy blocks

User: "Show me everyone in the marketing team's availability next week" Agent:

1. Lists users in the Marketing group via list-users.js --group "Marketing"
2. Runs get-schedule.js for all their emails
3. Presents a visual free/busy summary

Error Handling

Error	Cause	Fix
401 Unauthorized	Token expired or wrong credentials	Re-run get-token.js, check env vars
403 Forbidden	Missing Admin Consent	Ask IT admin to grant consent in Azure Portal
404 Not Found	User email doesn't exist	Verify email via list-users.js
No slots found	Everyone is busy	Widen time range or reduce attendees

Security Notes

• Credentials are read from env vars only — never log or echo them
• This skill has read-only access to calendars (Calendars.Read)
• It cannot create, edit, or delete any events
• To restrict which mailboxes the app can read, ask your IT admin to set an App Access Policy in Exchange Online:

  New-ApplicationAccessPolicy -AppId <ClientId> -PolicyScopeGroupId <GroupId> -AccessRight RestrictAccess
