lark-calendar

A tool for managing Feishu calendars, meetings, attendees, and meeting rooms. Feishu is a workplace collaboration platform used for schedules and team coordination.

In plain words
What is it for?
Use it to view or search events, create and update meetings, manage attendees, check availability, find suitable times, and reserve meeting rooms.
Why use it?
It removes the need to handle calendar availability, invitations, and rooms as separate manual steps. It also distinguishes upcoming scheduling from records of past video meetings.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lark-calendar scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

92% identical to lark-calendar — 86 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚙️ Cowork / Claude Desktop 执行环境说明(自动注入)

本技能依赖本地 lark-cli@larksuite/cli,可用 command -v lark-cli 定位)及其 ~/.lark-cli 登录态(应用密钥存于 macOS keychain)。

在 Cowork 中运行任何 lark-cli 命令时,必须在本地 macOS 上执行(使用 Desktop Commander 的 start_process / interact_with_process,或其它本地 shell 工具),不要用隔离的 Linux 沙箱 mcp__workspace__bash——沙箱里没有 lark-cli、也读不到 keychain。 执行前确保 npm 全局 bin 目录(npm prefix -g 输出目录下的 bin)在 PATH 中。

(在 Claude Code 中可忽略本说明,lark-cli 在本机 shell 直接可用。)

calendar (v4)

开始前先读 ../lark-shared/SKILL.md(认证、权限处理)。

CRITICAL — 凡涉及预约日程/会议室、调整时间或查询/搜索会议室,第一步 MUST 读 references/lark-calendar-schedule-meeting.md。仅编辑字段(改标题/描述)或增删参会人(不涉及时间和会议室)时可跳过,直接读 references/lark-calendar-update.md

身份

日程归属选身份:

  • 查看/管理登录用户本人的日程 → --as user(默认,绝大多数场景)。
  • 查看/管理 bot 自己创建/拥有的日程 → --as bot
# 用户本人日程 → user
lark-cli calendar +agenda --as user
# bot 自建或参与的日程 → bot
lark-cli calendar +agenda --as bot

Shortcuts

Shortcut 说明
+agenda 查看日程安排(默认今天)
+meeting 通过日程事件 ID 获取关联的视频会议信息(meeting_id、meeting_note),日程开过视频会议才会有meeting_id
+create 创建日程并邀请参会人(ISO 8601 时间)
+update 更新既有日程字段,或独立增量添加/移除参会人和会议室
+freebusy 查询用户主日历的忙闲信息和 RSVP 状态(纯查询场景;预约场景走 +suggestion
+room-find 针对一个或多个明确的时间块查找可用会议室(无明确时间时禁止直接调用,需先走 +suggestion)
+rsvp 回复日程(接受/拒绝/待定)
+suggestion 根据非明确时间或一段时间范围,推荐多个可用时间块方案

+get — 单日程详情

通过 calendar_id + event_id 获取单个日程详情。

# calendar_id不传,默认primary
lark-cli calendar +get --calendar-id <calendar_id> --event-id <event_id>

日程描述统一使用 description 一个字段,按 Markdown 富文本处理。读取日程时 description 返回 Markdown 富文本(仅有纯文本描述时返回该纯文本);创建/更新日程时也通过 --description 传入 Markdown。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
