lark-cli: Official Command-Line Interface for Lark and Feishu with Agent-Native Design

Repositorylarksuite/cliTool

The open-source Go utility lark-cli provides terminal and AI Agent access to the Lark/Feishu collaboration suite. It supports core services like Docs, Sheets, Mail, and Calendar with structured Agent skills and hardened security controls.

Key points

  1. Official CLI maintained by Larksuite featuring over 200 commands and 26 built-in AI Agent Skills.
  2. Broad service coverage including Messenger, Docs, Base, Sheets, Calendar, Mail, Tasks, and Meetings.
  3. Three-layer architecture offering shortcuts, synced API commands, and raw platform endpoints.
  4. Optimised for AI Agents with structured output, concise parameters, and prompt injection mitigation.
  5. Security features include OS-native keychain storage and terminal output sanitisation.
  6. Implemented in Go (v1.23+) and distributed under the MIT licence.

Why it matters

Exposing business suites directly to autonomous AI agents requires predictable interfaces and robust security boundaries. lark-cli illustrates how large workspace platforms can provide agent-ready CLI bindings out of the box.

Analysis

The project addresses integration friction between workspace suites and autonomous coding or automation agents. By offering structured CLI skills alongside raw API commands, it caters to both human developers in the terminal and LLM pipelines requiring stable JSON outputs. The target audience spans solo engineers building custom agent workflows to enterprise teams integrating Lark capabilities with centralized credential vaults and audit logs. Backed by the official Larksuite team and showing high engagement metrics, the project demonstrates strong architectural maturity.
