A workflow that uploads a large local file to Yandex Disk, creates a public link, and emails that link. Yandex Disk is an online file-storage service.

In plain words
What is it for?
Use it to send large files by email as links, with an optional preview using a dry run. It is not for sending the file as a normal attachment.
Why use it?
Email attachments may be too large or may not be the right way to share a file. The workflow also preserves the public link if sending the email fails after upload.

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

yacli-send-link-by-mail 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 10d 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.

What it actually says

Отправить ссылку на большой файл по почте

Кросс-сервисный сценарий: локальный файл -> Яндекс Диск -> публичная ссылка -> письмо.

Шаги

  1. Уточни путь к локальному файлу, путь disk:/..., получателя и тему письма.

  2. Если пользователь не дал текст письма, используй короткий вежливый body.

  3. Проведи flow одной командой:

yacli mail send-link [email protected] "Материалы" "Отправляю ссылку" --source ./archive.zip --path disk:/docs/archive/archive.zip
  1. Если сначала нужен preview без write-действий, используй:
yacli mail send-link [email protected] "Материалы" "Отправляю ссылку" --source ./archive.zip --path disk:/docs/archive/archive.zip --dry-run

Заметки

  • Это правильный путь для больших файлов, которые не стоит слать обычным вложением.
  • Если upload прошёл, а SMTP-отправка потом упала, yacli должен вернуть public_url, чтобы ссылка не потерялась.
  • Если пользователь хочет именно attachment, а не ссылку, используй workflow yacli-send-file-by-mail.

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.
