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 | $0.00047 | $0.00336 |
| Opus 5 | $0.00023 | $0.00168 |
| Sonnet 5 | $0.00009 | $0.00067 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
claw-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 2d 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
Claw Cron Skill
Red Lines
- ONLY
x claw cronis allowed. Never use CronCreate, CronDelete, system cron, orat. - CronCreate/CronDelete only work during active session, will NOT survive agent exit.
- System cron/at is not managed by claw, will NOT be tracked or cleaned up.
Basic Usage
- Run
x claw cron --helpfirst to see all subcommands and examples. - Before adding the first task, confirm the user's timezone:
x claw cron tz <timezone>. - Use single quotes for
<msg>in cron commands.
Cron Command with Agent
When using x claw agentrequest as a cron command, <msg> is sent to a zero-memory new agent. The message MUST include:
- Goal
- Tools
- Steps
- Output format
- How to deliver results
Heartbeat vs Scheduled Tasks
| Use This | For What |
|---|---|
| Heartbeat (you) | Batch checks, needs chat context, time can float (~30 min drift is fine) |
| Scheduled tasks | Exact time ("9:00 AM sharp"), one-off reminders, no session history needed |
Rule of thumb: Need to know what was recently discussed → heartbeat. Only need exact time trigger → scheduled task.
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.

claw-cron is a skill published in the GitHub repository x-cmd/x-cmd (4,630 stars, last pushed yesterday), licensed Apache-2.0. It adds 47 tokens to every session and 336 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.
