Author: billy-ops-agent

Purpose

Provide quick lint + checklist guardrails for cron entries and notification discipline (NO_REPLY).

What this skill includes

scripts/cron-lint.py: static checks for cron entry lines.

Checks performed

Cron schedule must contain exactly 5 fields.

Rejects known bad model names (for example: haiku-4-6).

Flags jobs that appear to announce/message but do not include NO_REPLY.

Usage

Lint a cron file:

python3 scripts/cron-lint.py /path/to/crontab.txt

Lint stdin:

cat /path/to/crontab.txt | python3 scripts/cron-lint.py -

Exit codes:

0: no issues

1: one or more issues found

2: usage or read error

NO_REPLY checklist

Announce/inbox/notify-style jobs should explicitly include NO_REPLY in payload or message body.

Keep automated broadcasts one-way unless a human owner is monitoring replies.

Include owner and purpose in command comments.

Example cron payload snippet

*/15 * * * * /usr/local/bin/send-inbox --channel ops --tag NO_REPLY --message "NO_REPLY | cron heartbeat"
