name: google-calendar-scheduler description: Check Google Calendar calendars, find free time, schedule meetings, and update events via the Google Calendar API. Use this skill when users want help scheduling or updating meetings — list calendars, show event details for a day or range, find free time slots, search for events, create events from structured details, adjust or delete existing events after confirmation, and check current date/time for timezone-aware scheduling.

Google Calendar Scheduler

Access Google Calendar via the Google Calendar API with OAuth authentication. Check calendars, find free time, schedule meetings, and update events.

This skill uses ClawLink for hosted connection flows and credentials so you do not need to configure Google Calendar API access yourself.

Setup in 3 Steps

Step 1: Install	Step 2: Pair Account	Step 3: Connect Google Calendar

Install

Install the verified ClawLink plugin from ClawHub. After the user confirms, complete the full setup so ClawLink tools are visible in the next OpenClaw chat.

openclaw plugins install clawhub:clawlink-plugin
openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
openclaw gateway restart

Then tell the user: "OpenClaw has been restarted. Send /new as a standalone message to start a fresh chat, then ask for Google Calendar again."

Quick Start

# List calendars
clawlink_call_tool --tool "googlecalendar_list_calendars" --params '{}'

# Get current date/time for timezone-aware scheduling
clawlink_call_tool --tool "googlecalendar_get_current_date_time" --params '{"timezone": "America/New_York"}'

# List events for a specific day
clawlink_call_tool --tool "googlecalendar_events_list" --params '{"calendar_id": "primary", "time_min": "2025-01-15T00:00:00Z", "time_max": "2025-01-16T00:00:00Z"}'

# Find free time slots
clawlink_call_tool --tool "googlecalendar_find_free_slots" --params '{"time_min": "2025-01-15T09:00:00Z", "time_max": "2025-01-15T18:00:00Z", "calendar_ids": ["primary"], "meeting_duration_minutes": 60}'

Authentication

All Google Calendar tool calls are authenticated automatically by ClawLink using the user's connected Google account.

No API key is required in chat. ClawLink stores the OAuth token securely and injects it into every Google Calendar API request on the user's behalf.

Getting Connected

1. Install the ClawLink plugin (see Install above).
2. Pair the plugin with clawlink_begin_pairing if it is not configured yet.
3. Open https://claw-link.dev/dashboard?add=google-calendar and connect Google Calendar.
4. Call clawlink_list_integrations to verify the connection is active.

Connection Management

List Connections

clawlink_list_integrations

Response: Returns all connected integrations. Look for google-calendar in the list.

Verify Connection

clawlink_list_tools --integration google-calendar

Response: Returns the live tool catalog for Google Calendar.

Reconnect

If Google Calendar tools are missing or the connection shows an error:

1. Direct the user to https://claw-link.dev/dashboard?add=google-calendar
2. After they confirm, call clawlink_list_integrations to verify
3. Then call clawlink_list_tools --integration google-calendar

Security & Permissions

• Access is scoped to calendars accessible to the connected Google account.
• All write operations require explicit user confirmation. Before executing any event create, update, move, or delete, confirm the intended effect with the user.
• Destructive actions (deleting events, clearing calendars) are marked as high-impact and must be confirmed.
• Moves and deletions of events with attendees affect other people's calendars — treat these as especially sensitive.

Code Examples

List today's events

clawlink_call_tool --tool "googlecalendar_events_list" \
  --params '{
    "calendar_id": "primary",
    "time_min": "2025-01-15T00:00:00-05:00",
    "time_max": "2025-01-15T23:59:59-05:00",
    "single_events": true,
    "order_by": "startTime"
  }'

Find free time for a meeting

clawlink_call_tool --tool "googlecalendar_find_free_slots" \
  --params '{
    "time_min": "2025-01-15T09:00:00-05:00",
    "time_max": "2025-01-15T17:00:00-05:00",
    "calendar_ids": ["primary"],
    "meeting_duration_minutes": 60
  }'

Create a meeting event

clawlink_call_tool --tool "googlecalendar_create_event" \
  --params '{
    "calendar_id": "primary",
    "summary": "Team Sync",
    "description": "Weekly team synchronization meeting",
    "start_datetime": "2025-01-15T10:00:00",
    "event_duration_minutes": 60,
    "timezone": "America/New_York",
    "attendees": ["colleague@example.com"]
  }'

Update an event

clawlink_call_tool --tool "googlecalendar_patch_event" \
  --params '{
    "calendar_id": "primary",
    "event_id": "abc123xyz",
    "summary": "Updated Team Sync",
    "start_datetime": "2025-01-15T11:00:00",
    "event_duration_minutes": 90
  }'

Discovery Workflow

1. Call clawlink_list_integrations to confirm Google Calendar is connected.
2. Call clawlink_list_tools --integration google-calendar to see the live catalog.
3. Treat the returned list as the source of truth. Do not guess or assume what tools exist.
4. If the user describes a capability but the exact tool is unclear, call clawlink_search_tools with a short query and integration google-calendar.
5. If no Google Calendar tools appear, direct the user to https://claw-link.dev/dashboard?add=google-calendar.

1. For unfamiliar tools, ambiguous requests, or any write action, call clawlink_describe_tool first.
2. Use the returned guidance, schema, whenToUse, askBefore, safeDefaults, examples, and followups to shape the call.

3. Prefer read, list, search, and availability operations before writes.
4. For event changes or other high-impact actions, call clawlink_preview_tool first, then confirm with the user.
5. Execute with clawlink_call_tool. Pass confirmation only after the preview matches the user's intent.
6. If the tool call fails, report the real error. Do not invent results or restate the failure as a missing capability unless the live catalog supports that conclusion.

Notes

• Timezone-aware scheduling: Always use IANA timezone identifiers (e.g., America/New_York, Europe/London) not abbreviations.
• UTC timestamps ending in Z are interpreted in UTC regardless of calendar timezone — use timezone-offset timestamps for local date queries.
• Primary calendar is referenced as calendar_id: "primary".
• Events with attendees automatically send invitations via Google Calendar.
• Deleting or moving events with attendees affects their calendars too — always confirm.
• No conflict checking is performed before event creation — use find_free_slots to detect overlaps.

Error Handling

Troubleshooting: Tools Not Visible

1. Check that the ClawLink plugin is installed: bash openclaw plugins list
2. If the plugin is installed but tools are missing, tell the user to send /new as a standalone message to reload the catalog.
3. If a fresh chat does not help, run: bash openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json openclaw gateway restart
4. After restart, tell the user to send /new again and retry.

Troubleshooting: Invalid Tool Call

1. Ensure the integration slug is exactly google-calendar.
2. Use clawlink_describe_tool to verify parameter names and types before calling.
3. For write operations, always call clawlink_preview_tool first.

这个Skill质量中等偏下。它提供了丰富的使用文档，包括工具说明、代码示例和故障排除指南，文档本身编写得较为详尽。但它的本质是通过第三方服务ClawLink间接调用Google Calendar，用户需要额外配置OAuth连接，架构复杂且依赖外部服务。如果ClawLink服务不稳定或不可用，整个Skill将完全失效。实际功能覆盖全面，包含日历管理、事件调度、查找空闲时间等，但缺少独立的代码实现，过于依赖中间层。推荐优先选择有直接API集成的日历Skill。
