OpenAI Agents API adds Automations: scheduled messages to new or running sessions

An OpenAI engineer announced Automations for the Agents API, with documentation and a cookbook; the OpenAI Developers account reposted the announcement. According to that post:

• Scheduling. The Agents API can schedule a message to be sent to a session that is already running, or create a new session on a schedule.
• Timing. A task can recur on a cron expression or run once at a given timestamp.
• Agents manage their own schedules. With the automations tool added, an agent can create, update or remove its own schedules from natural-language instructions.
• Suggested uses. Reviewing monthly spending, building a daily agenda from calendar, email and Slack, checking restaurant availability, and checking a flight price every day.
