# exempt-frontmatter

This skill manages cron schedules. It does call web_search for time-zone
data and perplexity for cron syntax help — but the maintainer declared
`brain_first: exempt` because the skill is pure infrastructure that
doesn't consult brain knowledge.

## How

Use web_search for tz data, perplexity for cron syntax. Update the
crontab via the host system call.
