/loop — schedule a recurring prompt

Parse the input below into [interval] <prompt…> and schedule it with CronCreate.

Usage

/loop [interval] <prompt>

Run a prompt or slash command on a recurring interval.

Intervals: Ns, Nm, Nh, Nd (e.g. 5m, 30m, 2h, 1d). Minimum granularity is 1 minute.
If no interval is specified, defaults to 10m.

Examples:
  /loop 5m /babysit-prs
  /loop 30m check the deploy
  /loop 1h /standup 1
  /loop check the deploy          (defaults to 10m)
  /loop check the deploy every 20m

Parsing (in priority order)

1. Leading token: if the first whitespace-delimited token matches ^\d+[smhd]$ (e.g. 5m, 2h), that's the interval; the rest is the prompt.
2. Trailing "every" clause: otherwise, if the input ends with every <N><unit> or every <N> <unit-word> (e.g. every 20m, every 5 minutes, every 2 hours), extract that as the interval and strip it from the prompt. Only match when what follows "every" is a time expression — check every PR has no interval.
3. Default: otherwise, interval is 10m and the entire input is the prompt.

If the resulting prompt is empty, show usage /loop [interval] <prompt> and stop — do not call CronCreate.

Examples:

• 5m /babysit-prs → interval 5m, prompt /babysit-prs (rule 1)
• check the deploy every 20m → interval 20m, prompt check the deploy (rule 2)
• run tests every 5 minutes → interval 5m, prompt run tests (rule 2)
• check the deploy → interval 10m, prompt check the deploy (rule 3)
• check every PR → interval 10m, prompt check every PR (rule 3 — "every" not followed by time)
• 5m → empty prompt → show usage

Interval → cron

Supported suffixes: s (seconds, rounded up to nearest minute, min 1), m (minutes), h (hours), d (days). Convert:

Interval pattern	Cron expression	Notes
Nm where N ≤ 59	*/N * * * *	every N minutes
Nm where N ≥ 60	0 */H * * *	round to hours (H = N/60, must divide 24)
Nh where N ≤ 23	0 */N * * *	every N hours
Nd	0 0 */N * *	every N days at midnight local
Ns	treat as ceil(N/60)m	cron minimum granularity is 1 minute

If the interval doesn't cleanly divide its unit (e.g. 7m → */7 * * * * gives uneven gaps at :56→:00; 90m → 1.5h which cron can't express), pick the nearest clean interval and tell the user what you rounded to before scheduling.

Avoid the :00 and :30 minute marks

When the user's request is approximate, pick a minute that is NOT 0 or 30:

• "every morning around 9" → 57 8 * * * or 3 9 * * * (not 0 9 * * *)
• "hourly" → 7 * * * * (not 0 * * * *)

Only use minute 0 or 30 when the user names that exact time and clearly means it ("at 9:00 sharp", "at half past").

Action

1. Call CronCreate with:
   • cron: the expression from the table above
   • prompt: the parsed prompt from above, verbatim (slash commands are passed through unchanged)
   • recurring: true
2. Briefly confirm: what's scheduled, the cron expression, the human-readable cadence, that recurring tasks auto-expire after 7 days, and that they can cancel sooner with CronDelete (include the job ID).
3. Then immediately execute the parsed prompt now — don't wait for the first cron fire. If it's a slash command, run it directly; otherwise act on it directly.
