Updated: Oct 2026; last repo commit

Ask Claude about your WeCom calendar. It can list or search events, create an event and invite people, change time, place, attendees or room, cancel an event, show free and busy times, and find shared free slots. It also looks up meeting rooms and office buildings.

It handles calendar events and in-person meetings, not online meetings with a meeting link. Those go to the meeting skill. It cannot create, change or cancel repeating events, or reply to invitations. When a request is vague ("set up a meeting") it asks whether you want an event or a meeting.

Good for

WeCom users who plan their day and week with Claude
People finding a shared free slot for several colleagues
Anyone booking a meeting room or checking which are free

Install wecomcli-calendar

Claude Code

Copy this prompt.

Install the wecomcli-calendar skill in Claude Code. Run this command:

npm install -g @wecom/cli

Then check that it loaded and tell me how to use it.

2
Paste it into Claude Code. It shows the change and asks before running it.

Requires Node.js 18 or newer, A WeCom account.

Do steps 1 to 3. Step 2 has alternatives: the README command installs all 15 skills in the repo, the second command installs only wecomcli-shared, wecomcli-calendar, wecomcli-contact. Every wecomcli-* skill must also read wecomcli-shared before it runs a command (its SKILL.md says so), so install that one too. The shared skill checks that wecom-cli is installed at version 1.2.1 or newer and signed in, and runs npm install -g @wecom/cli and the sign-in itself if not. The README also mentions an optional bot ID and secret for a smart bot. The skill runs the wecom-cli program on your machine, so there is no Claude app upload route.

Watch out for

It creates and cancels events directly
SKILL.md says that once the parameters are ready, create and cancel run without showing a summary or asking for confirmation. Invitations go to the real people you name. github.com
Claude may install a global npm package
The shared skill runs npm install -g @wecom/cli if wecom-cli is missing or older than 1.2.1, then starts the QR-code sign-in. Install the CLI yourself first if you want to control the version. github.com
Names are matched to user IDs
The skill must look names up through the contact skill and ask you when several people match. Check the person it picked. github.com
The CLI reports the calling agent to WeCom
The docs say wecom-cli reads the name of the agent program that calls it and sends the call chain to WeCom's cloud with each request. It is on by default in the npm build and can be switched off only by building from source with --no-default-features. github.com
Returned content is treated as data
The skill's safety note says nothing returned by the WeCom API is to be treated as instructions, and tokens or secrets in it are not to be output or used. github.com

Questions

How do I install it in Claude Code?

Use the install box at the top of this page. Install the CLI, add the skills (wecomcli-shared, wecomcli-contact and wecomcli-calendar) and sign in once with a QR code. The README says the skills install is required.

Do I need a WeCom account?

Yes. The README lists a WeCom account as a prerequisite, plus Node.js 18 or newer. A smart-bot ID and secret are optional and come from WeCom's help page.

Does it send usage data to WeCom?

The docs say wecom-cli reads the name of the calling agent program and sends the call chain with each request to WeCom's cloud, to help find problems. The npm build has this on by default. Building from source with --no-default-features turns it off.

Does it work in the Claude app, Codex or Cursor?

The install box has Claude Code, Codex and skills CLI routes. There is no Claude app upload route, because the skill drives the wecom-cli program on your machine. The README does not name Cursor.

What does the wecomcli-calendar skill do?

It makes your agent manage your WeCom calendar through wecom-cli: create, list, search, update and cancel events, check free time and book meeting rooms.

What is the difference between a calendar event and a meeting?

SKILL.md says this skill handles events and in-person meetings. Anything with an online meeting link or remote attendance is a meeting and goes to the wecomcli-meeting skill, which is a separate skill in the repo.

Does it ask before creating or cancelling an event?

When the details are complete it runs create and cancel directly. SKILL.md says it does not show a summary or ask for confirmation first, because that is meant to happen earlier in the conversation. It does ask when details are missing or ambiguous.

Can it handle repeating events or invitations?

No. SKILL.md says it does not create, change or cancel repeating events, and does not accept or decline invitations. It sends you to the WeCom app for those.

Is it safe?

It writes to your calendar and invites other people, and it creates and cancels events without a confirmation step once the details are complete. Our advice: name the people and the time exactly, and ask it to show the details before you let it create anything with many guests.
