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

calendar-scheduling 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.

The scan reads SKILL.md. This mod also ships 3 executable files (tools/create_event/index.ts, tools/find_free_time/index.ts, tools/list_events/index.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

日历安排

何时使用

  • 查某段时间有没有会、找空档、创建日程

工作流

  1. 先确认时区(配置项 timezone,默认 Asia/Manila)和日期范围。
  2. list_events 看已有安排;需要空档时用 find_free_time(尊重 work_day_start / work_day_end)。
  3. 创建前复述:标题、开始、结束、地点、时区,等用户明确同意后再调 create_event(仅 master,且始终要求批准)。
  4. 若日历未启用,告诉用户去配置 CalDAV / Google / Microsoft,不要假装已创建。

注意

  • 没有时区偏移的时间按配置时区解释。
  • Google / Microsoft 使用 refresh_token(环境变量);用 pnpm --filter @zhin.js/plugin-calendar auth google|microsoft 获取。access token 仅内存缓存。
  • 操作哪本日历由配置 calendar_id 决定(Google 默认 primary,Outlook 默认账户主日历)。
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
