Written for no agent in particular: nothing here depends on one.

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.

Fable 5.1 $0.00028 $0.00942

Security

Grade A, and why

feishu-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 2mo 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.

核心约束

  • 时间格式：支持 "2026-03-10 10:00" 或 ISO 8601 "2026-03-10T10:00:00+08:00"
  • duration: 支持 "30m", "1h", "1h30m" 等格式
  • attendees: 使用 open_id（ou_ 开头），数组格式
  • 时区: 默认使用服务器时区，可通过 timezone 参数指定（如 "Asia/Shanghai"）
  • 日历 ID: 大部分操作默认使用主日历，可通过 calendar_id 指定其他日历
  • 重复日程: 使用 recurrence 参数（RRULE 格式），如 "FREQ=WEEKLY;BYDAY=MO"

常见错误

错误 原因 解决
无权限访问日历 未授权 calendar 相关 scope 执行 OAuth 授权
参会人无法添加 user_id 格式错误 确认使用 open_id（ou_开头）

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.
