What This Skill Covers
- When a Worker is invoked via a Cron Trigger, the scheduled() handler handles the invocation.
- Main sections:
Background,Syntax,Properties,Handle multiple cron triggers,Methods.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
