call-prep is a skill for Claude Code from tonydzi/second-brain-starter-kit. It costs 101 tokens per session (2,572 once invoked), scanned A, original, MIT.

A pre-call briefing workflow that first identifies the correct calendar booking and its contact details, then gathers information about that person. It avoids guessing between people who share a name.

In plain words
What is it for?
Use it before a meeting to confirm who booked it, find their background in the team's records, and prepare a brief with the correct person in mind.
Why use it?
It reduces the risk of preparing for or contacting the wrong person. Starting with the booking provides reliable identifiers such as an email address, phone number, or messaging handle.

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.

Security

Grade A, and why

call-prep 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 22d ago.

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.

/call-prep — подготовь меня к звонку

🧒 Доклад Антону кончается блоком «Простыми словами» ([[eli5-always]]).

Боль (14.09.2026): «у меня звонок с каким-то Барри, кто он». Сессия пошла в волт+Telegram, нашла 12 Барри и подготовила НЕ того. Верный лежал в ящике bb одним письмом Calendly «New Event: [человек] [человек] - 20:30 Mon, 14 Sep 2026 - 1-on-1 with Tony» с email, телефоном, TG-хендлом из формы и Meet-ссылкой. Антон: «первым делом календарь, потом почта; у нас есть ещё Calendly».

Закон скилла: имя без брони = НЕ идентификация. Сначала бронь → ключи (email · телефон · TG-хендл из формы) → только по КЛЮЧУ ищем человека в волте/CRM/Telegram. Совпадение по имени не считается.

Пути: VAULT=${OBSIDIAN_VAULT:-$HOME/Obsidian/<vault>}, IMP=${IMPORTS_ROOT:-$HOME/Obsidian/_imports}.

Шаг 1. Двери брони — строго по порядку, первая живая даёт истину

1а. Calendly-коннектор (истина броней, аккаунт paloaltolab) — нужен Claude

meetings-list_events (окно сегодня−завтра) → list_event_invitees по event_uri → ответы формы (TG-хендл). Проверка наличия: ToolSearch «calendly» / «meetings».

  • [машина флота] ([машина флота]), замер 14.09.2026: ToolSearch «calendly meetings list_events invitees» и «+meetings» → коннектора НЕТ. Живёт на хабе. Нет коннектора → не стоп, иди дальше.

1б. Снимок Calendly для call_reminders

python3 $IMP/crm-engine/call_reminders.py --calendly $IMP/crm-engine/reports/calendly-bookings.json (брифинг окна 24ч/1ч, время в поясе Антона и гостя; паспорт ~/.claude/scripts/docs/call-reminders.md). Снимок пишет тот, у кого есть Calendly MCP (рутина inbound-triage-daily, шаг 6а, на хабе). Ключ связи бронь↔CRM = TG-хендл, который лид сам написал в форме.

  • [машина флота], замер 14.09.2026: --help отвечает, но файла reports/calendly-bookings.json на узле НЕТ → дверь пустая. Проверь возраст файла (pulled_at), если он есть; старше суток = подсказка, не истина.

1в. Google Calendar [рабочий аккаунт]

python3 $IMP/call-bot/gcal_events.py

  • [машина флота], замер 14.09.2026: NOT AUTHORIZED: no calendar token for 'bb' — run: python gcal_auth.py bb. Не авторизовано на [машина флота]. Сам не авторизую (нужен человек в браузере) — строка в «НЕ проверено». В живой сессии с коннектором Google Calendar (нужен Claude) — list_events по [рабочий аккаунт]@gmail.com, Europe/Lisbon.

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.
