cron

A scheduler for one-time reminders and repeated tasks. It can run a message or ask the agent to perform a task on a schedule.

In plain words

It prevents reminders and recurring checks from being forgotten or run manually.

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.

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

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 3d 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

Use the cron tool whenever the user asks for reminders, recurring checks, or one-time scheduled tasks.

Actions

  • add: create a schedule
  • list: list current jobs
  • remove: delete a job
  • enable / disable: toggle execution
  • run: force immediate run

Add examples

Fixed reminder:

{"action":"add","message":"Time to take a break","every_seconds":1200}

Agent task on every run:

{"action":"add","prompt":"Check repo CI status and report only failures","every_seconds":600}

One-time schedule:

{"action":"add","message":"Remind me about the meeting","at":"2026-03-02T18:00:00Z"}

Timezone-aware cron:

{"action":"add","prompt":"Morning standup","cron_expr":"0 9 * * 1-5","tz":"America/Vancouver"}

List and remove:

{"action":"list"}
{"action":"remove","job_id":"abc123"}

Notes

  • prompt and message are both accepted; use prompt for agent tasks.
  • Convert natural-language schedules into every_seconds, at, or cron_expr.
  • For add, only provide session_id/channel/target when routing to another session or destination.
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.
