Cron Scheduler
When to Use
User says schedule this or task matches this capability
User says run daily or task matches this capability
User says cron job or task matches this capability
User says set timer or task matches this capability
User says every morning or task matches this capability
Workflow
Parse the schedule expression (cron, interval, or natural language).
Present the proposed trigger, task scope, notification channel, and next three run times.
Obtain explicit user approval before writing or enabling any recurring schedule; otherwise provide an inactive copy-paste configuration only.
After approval, save only the named configuration and do not enable background execution, outbound notifications, or external actions beyond the approved scope.
On trigger, execute only the preapproved task. Pause for fresh approval before any consequential external action not explicitly covered by that approval.
