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 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.

What it actually says

Cron

Use the cron tool to schedule reminders or recurring tasks.

Three Modes

  1. Reminder - message is sent directly to user
  2. Task - message is a task description, agent executes and sends result
  3. 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 owner/repo 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.

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.
