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 | $0.00034 | $0.00547 |
| Opus 5 | $0.00017 | $0.00273 |
| Sonnet 5 | $0.00007 | $0.00109 |
| Haiku 4.5 | $0.00003 | $0.00055 |
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 12d 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
Cron Scheduler
适用场景
- 用户说“每天9点提醒我开会”“每周一早上发周报”
- 用户说“看看哪些cron失败了”“暂停某个任务”
- 需要对
cron/jobs.json做健康审计与优化建议
命令
1) 创建任务（推荐）
python3 skills/cron-scheduler/scripts/cron_helper.py create \
--name "每日提醒" \
--cron "0 9 * * *" \
--message "提醒我查看任务" \
--delivery announce \
--to "chat:oc_xxx"
一次性任务：
python3 skills/cron-scheduler/scripts/cron_helper.py create \
--name "一次性提醒" \
--at "2026-03-15T01:00:00Z" \
--message "提醒内容"
2) 查询任务
python3 skills/cron-scheduler/scripts/cron_helper.py status
python3 skills/cron-scheduler/scripts/cron_helper.py failures
3) 启停与手动触发
python3 skills/cron-scheduler/scripts/cron_helper.py disable --id <job_id>
python3 skills/cron-scheduler/scripts/cron_helper.py enable --id <job_id>
python3 skills/cron-scheduler/scripts/cron_helper.py run --id <job_id>
4) 审计优化
python3 skills/cron-scheduler/scripts/cron_audit.py
设计原则
- 薄封装：不重写调度引擎，只封装
openclaw cronCLI - 性能优先：仅按需执行，不常驻，不新增后台进程
- 安全默认：默认
sessionTarget=isolated、低价值任务默认delivery=none - 时区明确：默认

What ships with it
5 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.
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.
- 12d ago First seen · 70 lines · 34 tokens per session scan A f7258d81e902
cron-scheduler is a skill published in the GitHub repository xyva-yuangui/XyvaClaw (21 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 547 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.
