What is appointment-confirm?

A phone workflow for confirming one existing appointment and returning the answer as structured data. It supports dry-run and fixture modes and leaves calendar changes to a human.

It asks whether the recipient can attend, records yes or no and any requested time, and gives a coordinator an evidence-backed disposition.

It reduces manual confirmation work while avoiding automatic booking, rescheduling, cancellation, or calendar updates. It is limited to appointments the recipient already knows about.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.01012
Opus 5.5	$0.00015	$0.00405
Sonnet 5.5	$0.00008	$0.00202
Haiku 4.5	$0.00004	$0.00101

Security

Grade A, and why

appointment-confirm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/preview.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

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

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
