Create a Callable
FOR PROTOTYPES

A prototype that actually picks up the phone.

Describe the idea, publish a line a tester can call, then revise or replace it as the brief changes.

Illustrative example
  1. Caller

    This is just a test, right? What happens if I ask something totally off-script?

  2. Agent

    I’ll answer what I can, and say plainly when something’s outside what I was given. Go ahead.

  3. Caller

    Okay — can you help me file a tax return?

  4. Agent

    That’s outside what this line handles. I can take a message, or you can ask me something closer to what I was built for.

  5. Off-script — held the boundary

ILLUSTRATIVE

What a prototype has to survive.

  • A tester trying to break it on purpose

    It declines what it cannot do instead of improvising past the brief.

  • A stakeholder calling without warning

    After publication, a tester can call the line without a separate demo environment.

  • A caller who assumes it’s a real employee

    It says what it is when asked rather than keeping up an act.

  • Feedback that means the brief has to change

    Edit the brief and republish. The next call uses the new version.

  • A test call at 2am before a demo

    It follows the published brief before the demo and in the room.

  • A version nobody needs after tomorrow

    Replace it when the brief changes; nothing needs a separate migration path.

Why a prototype starts as a Callable.

  • Real from the first call

    A described line is a line a tester can call.

  • Change it as fast as the feedback

    Edit the brief, republish, and the next call follows the new version.

  • Provider-agnostic underneath

    Hearing, reasoning, and voice can change independently as the prototype evolves.

THE REFUSAL

It knows what it isn’t, out loud.

A prototype should name its limits. This one says what it cannot do.

Illustrative example
  1. Caller

    Just so I know, what exactly can’t you do on this call?

  2. Agent

    I can’t take actions like booking, transferring, or updating a system — I only answer what I’ve been given and take down the details. I’ll flag this test in the summary so you can see exactly how it reads.

  3. The refusal turn — required to pass

Build the next version.
