Lark CLI Skill: Calendar — Event & Schedule Management

What it is

Lark Calendar is a CLI skill for the Lark/Feishu collaboration platform that lets you manage calendar events from the terminal. It supports viewing agendas, creating events, inviting attendees, checking free/busy status, and getting time suggestions.

This skill is part of the Lark CLI tool, which provides 200+ commands and 19 AI Agent Skills for the Lark/Feishu Open Platform. It works with Claude Code, OpenAI Codex, Cursor, and Gemini CLI.

How it saves time or tokens

The Lark Calendar skill eliminates context switching between your coding environment and the Lark web app for scheduling tasks. Instead of opening a browser tab, navigating to the calendar, and clicking through forms, you tell your AI agent to 'create a meeting with the engineering team at 3pm tomorrow' and it handles the API calls. Free/busy checking and time suggestions are particularly valuable when coordinating across multiple attendees' calendars.

How to use

1. Install the Lark CLI and calendar skill:

npm install -g @larksuite/cli
npx skills add larksuite/cli -y -g

1. Configure authentication:

lark-cli config init
lark-cli auth login --recommend

1. Use calendar commands:

# View today's agenda
lark-cli calendar agenda

# Create a new event
lark-cli calendar create --title 'Sprint Planning' \
  --start '2026-04-16T10:00' --duration 60

# Check free/busy for attendees
lark-cli calendar freebusy --emails alice@company.com,bob@company.com

# Get time suggestions for a group meeting
lark-cli calendar suggest --emails team@company.com --duration 30

Example

Using the calendar skill with an AI agent:

# Agent interaction
User: 'Schedule a 30-minute meeting with Alice and Bob
       sometime tomorrow afternoon'

# Agent uses Lark Calendar skill:
1. Calls freebusy to check Alice and Bob's availability
2. Calls suggest to find open 30-minute slots tomorrow 1-5pm
3. Presents options to user
4. Creates event with selected time and sends invites

Common pitfalls

• Not completing the authentication setup before using calendar commands results in API errors. Run lark-cli auth login first.
• The skill requires Lark/Feishu Open Platform API access. Your organization's admin must enable API access for your account.
• Time zone handling can cause scheduling errors. Ensure your lark-cli config includes the correct timezone setting.
