explain_cron | Translate a cron expression into plain English, list its upcoming run times in a specific timezone, and report the gotchas that make schedules misfire.
Use this whenever a cron expression needs to be read, verified, or explained — and prefer it over reasoning about the expression directly. Cron has several counter-intuitive rules that are easy to get wrong: day-of-month and day-of-week are combin params: expression*, timezone, count |
next_cron_runs | List the next run times for a cron expression in a specific timezone, with no prose.
Use this when the only question is "when does this next fire" — for example to check whether a job will run before a deadline, or to show a user their upcoming schedule. Do not compute these dates yourself: weekday arithmetic, month lengths, and daylight-saving shifts make manual calculation unreliable.
Returns params: expression*, timezone, count |
build_cron | Convert an English schedule description into a standard five-field cron expression, then explain and validate the result.
Use this when a user describes a schedule in words and needs the expression. This is a RULE-BASED converter, not a language model: it handles a fixed grammar and returns an error listing the supported phrasings when a phrase falls outside it. That refusal is deliberate — a pla params: phrase*, timezone |
