Scheduling Agent
Proposes times it can actually stand behind, and books nothing
- 8hard rules
- Things it must never do, enforced in every run
- 5handover rules
- Conditions where it stops and gives the work to a person
- 7output fields
- A structured result, not a paragraph you have to re-read
- ≤4steps per run
- Bounded work: at most 3 tool calls, enforced by the runtime
Read-only by design. This agent has no path to sending, spending, publishing or committing anything. Where that limit is the product, removing it would remove the reason to trust the output.
Overview
Scheduling tools either book — and eventually book over something they could not see, at a cost greater than the time they saved — or they send a link and hand the work back to the person you were trying not to inconvenience.
This proposes. It reads the availability and constraints you supplied, applies the rules that actually matter — working hours in each participant's own timezone, the buffer people need between calls, the days someone has said they do not take meetings — and returns a small number of slots that work for everyone it can see.
What makes it usable is the second half: it states exactly what it could not see. A calendar it was not given, a timezone nobody specified, a participant whose availability is unknown. A proposal that admits its blind spot can be judged; a confident one that turns out to be wrong costs an apology and a reschedule. It books nothing and sends nothing.
Benefits
No double bookings
Because it never books, and never claims a slot is held.
The back-and-forth, gone
Without pushing the work back to the other side.
Fewer awkward invites
Nobody asked to join at 6am their time.
What it does
States what it could not see
A calendar it was not given, a timezone nobody stated. A proposal that admits its blind spot can be judged.
Timezones per participant
Working hours are local. 9am for you is the middle of someone's night, and that is the commonest error.
Respects the rules people actually have
Buffers between calls, no-meeting days, the hour nobody should be asked to give up.
A few good slots, not thirty
Thirty options is not helpfulness, it is the decision handed back to the recipient.
Flags what makes a slot fragile
Back-to-back with something else, or resting on availability that was inferred rather than given.
Books nothing
It proposes. Putting something in someone's calendar is a commitment a person should make.
What this changes
What this changes about your week
- It takes over
- The back-and-forth of finding a time that works across timezones.
- Done today by
- Everyone, several times a week.
- How often
- Every meeting that involves more than two diaries.
- Typical manual effort
- Six messages and two days for one 45-minute call.
Why Productivity in particular. It states what it could not see. Assistants that book eventually book over a calendar they were not given, and the recovery costs more than the scheduling ever saved.
Runs unattended
Started by you or by an event, and it finishes on its own. Nothing waits for someone to be at a desk.
The same standard every time
The two-hundredth item is held to the bar the first one was. Consistency is the part people cannot sustain.
It cannot act on its own
Scheduling Agent has no path to sending, spending or committing. That limit is why its output is safe to act on.
How it runs
This agent runs server-side through the PROMIVO runtime. Each run is logged step by step and every tool call is permission-checked before it executes.

FAQ
Why will it not book?
Because booking assumes it can see everything, and it cannot. A tool that books over a calendar it was not given costs more than the scheduling it saved, and it always eventually does.
Does it connect to my calendar?
It works from the availability you supply or that a connected calendar returns. Whatever it was not given, it reports rather than assuming free.
Will it email the participants?
No. It gives you the slots and the wording. Sending is yours.
