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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00092 | $0.05232 |
| Opus 5.5 | $0.00037 | $0.02093 |
| Sonnet 5.5 | $0.00018 | $0.01046 |
| Haiku 4.5 | $0.00009 | $0.00523 |
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 1mo 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.
This is a copy
92% identical to lark-calendar — 11 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 — 260 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
按日程归属选身份：
- 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
对话人称映射：「我」= 登录用户，「你」= 应用（bot）；作为字段取值的人称（参会人、会议 owner 等）不参与身份判定，如「你创建日程，邀请我、会议 owner 为我」→ --as bot 创建，登录用户仅作参会人与会议 owner。
# 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

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.

agent-check
Validate custom agent file format and structure. Use after creating or editing an agent, before committing agent changes, or when an agent fails to load.
skill-check
Validate skill/command file format and structure. Use after creating or editing a skill, before committing skill changes, or when a skill fails to load or trigger.
