A callback workflow through Mango Office, a business phone service. It can call a customer, find the resulting recording, and send an SMS if the customer does not answer.

Use it to place a callback, check whether the conversation happened, retrieve its recording, and send a short text message after an unanswered call.

It keeps the call outcome, recording, and missed-call message together instead of requiring separate phone-system steps. It also helps ensure the call uses the correct employee extension.

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	$0.00024	$0.00610
Opus 5	$0.00012	$0.00305
Sonnet 5	$0.00005	$0.00122
Haiku 4.5	$0.00002	$0.00061

Security

Grade A, and why

callback 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 yesterday.

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.

What it actually says

/callback — Обратный звонок и разбор разговора

Алгоритм

Уточни, с какого внутреннего номера звоним. Если пользователь не знает — вызови get_users с limit и покажи список сотрудников с их внутренними номерами.
Вызови make_call с from (внутренний номер или SIP-аккаунт инициатора), to (номер назначения в E.164 или внутренний) и опционально line — это CallerID, который увидит клиент. Сначала поднимется трубка сотрудника, потом пойдёт вызов клиенту.
После разговора вызови get_calls с date_from и date_to за последние минуты, найди запись по номеру клиента и возьми из неё recording_id.
Вызови get_recording с recording_id и action = play (ссылка на прослушивание) или download (скачать файл).
Если клиент не ответил — вызови send_sms с from_extension (внутренний номер отправителя), to_number и text (до 1000 символов). Формулируй коротко: кто звонил, по какому вопросу, как связаться.
Отчитайся: состоялся ли разговор, есть ли запись, ушла ли SMS.

Формат ответа

## Обратный звонок

**От**: 101 (Иванов И.)
**Кому**: +79121234567
**Линия**: +74951234567
**Результат**: разговор состоялся, 3 мин 42 с

**Запись**: https://app.mango-office.ru/... (ссылка временная)

SMS не отправлялась — клиент ответил.

Важно

make_call инициирует звонок физически. Не вызывай его «для проверки» — у сотрудника зазвонит телефон.
Запись появляется не мгновенно: сразу после разговора get_calls может ещё не отдать recording_id. Повтори через минуту, прежде чем говорить, что записи нет.
Ссылка из get_recording с action = play живёт ограниченное время. Не сохраняй её как постоянную.
Записи разговоров — персональные данные. Не пересказывай содержимое без запроса.

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.

callback is a skill published in the GitHub repository theYahia/WWmcp (28 stars, last pushed yesterday), licensed MIT. It adds 24 tokens to every session and 610 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
