lark-im makes Claude work with Lark (Feishu) chat. It sends and replies to messages, searches chat history, lists and reads messages, downloads files and images, creates and updates group chats, lists members, adds reactions and flags, pins chats, and sends or handles interactive cards.

It starts when you want to send a message, search or read chats, download chat files, or manage groups. The description also lists urgent in-app, SMS and phone alerts. It can act as you or as a bot, and the two see different chats. The body is mostly English.

Good for

Team leads who want Claude to draft and send updates in Lark
Anyone who needs to search chat history or pull files from chats
Admins who create and manage group chats

Install lark-im

Claude Code

Copy this prompt.

Install the lark-im skill in Claude Code. Run this command:

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

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.

The README gives two routes. Option 1 (recommended) is npx @larksuite/cli@latest install. Option 2 builds from source and then runs npx skills add larksuite/cli -y -g, which the README marks as required. It does not say whether Option 1 also installs the skills, so this box runs both. Every lark-* skill needs the lark-cli program and sends Claude to lark-shared for sign-in. auth login --recommend picks commonly used scopes; use --domain to limit them.

Questions

What does lark-im do?

It lets Claude send, reply to, search and read messages and manage group chats in Lark (Feishu), as you or as a bot, using lark-cli im commands.

How do I install it?

Follow the install box at the top of the page. It needs the lark-cli program and the lark-shared skill, so install the whole set.

Will it send messages as me?

With --as user, yes: messages go out under your name using your token. With --as bot they come from the app bot, which only sees chats it has joined.

Can it read my past chats?

Yes. It can list and search messages and download files from chats your identity can see.

Can it send urgent alerts?

SKILL.md lists in-app, SMS and phone urgent alerts. They are bot-only, and the bot must be the sender and be in the conversation. Treat them as high-impact and approve each one yourself.

Is it safe?

README security note: after you authorize, the agent acts under your identity within the granted scope, and the README warns of prompt injection and data leaks. Review each send, and keep the bot out of group chats as the README advises.
