Appointment Confirm

Use this skill when a studio, clinic, or coordinator has explicit authority to place one disclosed phone call to confirm an existing booking. The call asks whether the recipient can attend the booked slot, captures a yes/no plus a confirmed or requested time, and returns fail-closed structured JSON.

This skill does not book, move, or cancel calendar events. A human reviews the result before any diary change.

When To Use

• Confirm a booked appointment the recipient already knows about
• Capture a decline or a requested move to a pre-approved window
• Leave a short voicemail that asks them to call the business back
• Produce an evidence-backed disposition for a coordinator

When Not To Use

• First-contact sales, lead qualification, or unsolicited marketing
• Medical, legal, financial, emergency, collections, or political calls
• Calling a number the user did not provide and authorize
• Hidden retries, recurring reminders, or automatic calendar writes
• Collecting payment, ID numbers, or health details

Required Inputs

• request_id: stable local identifier
• business_display_name: name disclosed on the call
• recipient_first_name
• to_phone_e164: E.164, authorized
• appointment.service, appointment.starts_at (ISO-8601 with offset), appointment.location
• timezone: IANA
• consent: must be true
• authorized_reason: why this specific call is allowed

Optional: reschedule_windows (max 6 ISO-8601 times the coordinator can actually honor).

Preflight

1. Confirm the user authorized this one confirmation call.
2. Confirm the phone is E.164 and came from the booking workflow.
3. Refuse if do_not_call is true or consent is not true.
4. Run a local preview before any CALL-E plan.

Dry-Run Preview

From the repository root (no CALL-E credentials, no network):

python3 apps/python/appointment-confirm/client.py --request skills/appointment-confirm/assets/sample-appointment.json
python3 apps/python/appointment-confirm/client.py --request skills/appointment-confirm/assets/sample-appointment.json --mock

From the app directory:

cd apps/python/appointment-confirm
python3 client.py --request fixtures/sample_appointment.json

Preview prints a masked phone, the CALL-E task, and the result schema. It does not dial.

CALL-E Goal Template

You are an AI phone assistant calling on behalf of {business_display_name}.
Disclose immediately that you are AI and that this is one appointment-confirmation call.
 
Speak with {recipient_first_name}. If you have the wrong person, apologise and end the call.
 
Purpose: confirm the existing {service} on {starts_at_friendly} at {location}.
Do not sell, collect payment, or give medical, legal, or financial advice.
 
Ask whether they can attend. Capture can_attend as yes, no, or unknown.
If yes, read the time back and capture confirmed_time.
If no, offer only these windows: {reschedule_windows}. Capture requested_time.
Do not infer yes from silence. Do not update any calendar.

Structured Result

{
  "can_attend": "yes | no | unknown",
  "confirmed_time": "ISO-8601 or empty",
  "requested_time": "ISO-8601 or empty",
  "disposition": "confirmed | declined | reschedule_requested | voicemail | no_answer | wrong_number | needs_human"
}

A confirmed result is not a calendar write. reschedule_requested, voicemail, and unknown all need a human.

Live Planning

Only after explicit user authorization and CALL-E authentication:

export CALLE_API_KEY="<server key>"
python3 apps/python/appointment-confirm/client.py --request <authorized-intake.json> --execute --confirm-consent

Planning via the CALL-E CLI is also valid and is not execution:

calle call plan --to-phone <E164_PHONE> --goal "<reviewed goal text>" --timezone Europe/London --language English --region GB

Do not run calle call start or this app's --execute unless the user separately confirms.

Cancellation And Idempotency

Idempotency key: appointment_confirm:{request_id}:{starts_at}. If the user cancels before dial, do not execute. If a result is ambiguous, route to a human rather than calling again.

Safety Notes

Read references/safety.md and references/examples.md before live planning.
