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 | $0.00008 | $0.00409 |
| Opus 5.5 | $0.00003 | $0.00164 |
| Sonnet 5.5 | $0.00002 | $0.00082 |
| Haiku 4.5 | $0.00001 | $0.00041 |
Grade A, and why
cron 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
100% identical to cron — 2 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.
What it actually says
Cron
Use the cron tool to schedule reminders or recurring tasks.
Three Modes
- Reminder - message is sent directly to user
- Task - message is a task description, agent executes and sends result
- One-time - runs once at a specific time, then auto-deletes
Examples
Fixed reminder:
cron(action="add", message="Time to take a break!", every_seconds=1200)
Dynamic task (agent executes each time):
cron(action="add", message="Check FarkhodovIslom/Tarantul GitHub stars and report", every_seconds=600)
One-time scheduled task (compute ISO datetime from current time):
cron(action="add", message="Remind me about the meeting", at="<ISO datetime>")
Timezone-aware cron:
cron(action="add", message="Morning standup", cron_expr="0 9 * * 1-5", tz="America/Vancouver")
List/remove:
cron(action="list")
cron(action="remove", job_id="abc123")
Time Expressions
| User says | Parameters |
|---|---|
| every 20 minutes | every_seconds: 1200 |
| every hour | every_seconds: 3600 |
| every day at 8am | cron_expr: "0 8 * * *" |
| weekdays at 5pm | cron_expr: "0 17 * * 1-5" |
| 9am Vancouver time daily | cron_expr: "0 9 * * *", tz: "America/Vancouver" |
| at a specific time | at: ISO datetime string (compute from current time) |
Timezone
Use tz with cron_expr to schedule in a specific IANA timezone. Without tz, the server's local timezone is used.
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 is a skill published in the GitHub repository FarkhodovIslom/Tarantul (6 stars, last pushed 1mo ago), licensed MIT. It adds 8 tokens to every session and 409 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings.
