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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.00656 |
| Opus 5 | $0.00019 | $0.00328 |
| Sonnet 5 | $0.00008 | $0.00131 |
| Haiku 4.5 | $0.00004 | $0.00066 |
Grade A, and why
cron-scheduler 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 10d 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.
What it actually says
定时任务调度指南
通过 cron 工具的 action 参数路由所有调度操作。
适用场景
- 精确时间调度（"每天早上 8 点"、"每周一 10 点"）
- 周期性提醒（"每隔 2 小时提醒我喝水"）
- 周期性 Agent 任务（"每天搜索最新 AI 资讯"、"每周生成周报"）
- 暂停 / 恢复 / 查询 / 删除既有任务
不适用场景
- 模糊持续关注（"留意 X 这事"）→
memory(action="create")记到记忆，由主动提醒引擎处理 - 一次性任务（"等会提醒我做 X"）→ 直接执行或用工作区登记，不创 cron
- 一次性较复杂任务的多步执行 → daily-manager 协调，不创 cron
工作流（按用户表达分流）
| 用户表达 | action |
|---|---|
| "每天/每周/每小时 X" | create |
| "看看我有哪些定时任务" | list |
| "X 任务先不跑了 / 暂停" | update 配 status="paused" |
| "X 任务恢复" | update 配 status="active" |
| "改下 X 的时间 / 内容" | update |
| "把 X 这个定时任务删了" | remove |
各路径要点：
- 任务指令清楚化：
instruction写清触发后做什么，避免歧义 - 高风险动作预声明：任务涉及删文件、联网下载、桌面自动化时，创建时让用户预授权
- 暂停优先于删除：用户说"先不跑了"用
update配status="paused"，不要直接remove - 删除会清执行日志：告诉用户后再执行
静默协议（独有）
任务被定时调度自动触发执行后，无内容要汇报（例行检查一切正常）时回复 TASK_SILENT（出现在回复开头或结尾），系统不推消息给用户。仅自动触发场景生效，用户在会话中显式问任务结果时正常回答。

What ships with it
1 file 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.
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.

cron-scheduler is a skill published in the GitHub repository ntygod/ZhiWei (138 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 656 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
