Provides a Feishu (Lark) calendar and task CLI that auto-discovers credentials from `~/.openclaw/openclaw.json` or environment variables and manages events/tasks via command-line scripts. It reads `FEISHU_APP_ID`/`FEISHU_APP_SECRET`, makes network calls to `https://open.larksuite.com/open-apis` and `https://open.feishu.cn/open-apis`, and exposes shell-invokable scripts (e.g., `node bin/create-event.mjs`); these behaviors are purpose-aligned and low risk.

This skill manages Feishu calendar events with automatic credential discovery and CLI/shell scripts for create/list/update/delete. It reads credentials from `~/.openclaw/openclaw.json` and env vars like `FEISHU_APP_ID`, writes `~/.feishu-config.json`, and calls `https://open.larksuite.com/open-apis` / `https://open.feishu.cn/open-apis`.
