What is yacli-shared?

A shared command-line foundation for Yandex Mail, Calendar, and Disk. A command-line tool is a program operated by typing commands, and this one returns machine-readable JSON by default.

Use it to add and select Yandex accounts, see the current account, connect Mail, Calendar, or Disk, and inspect which services are connected.

It provides one place to manage Yandex accounts, sign in to each service, switch between accounts, and check connection status.

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	$0.00056	$0.00656
Opus 5.5	$0.00022	$0.00262
Sonnet 5.5	$0.00011	$0.00131
Haiku 4.5	$0.00006	$0.00066

Security

Grade A, and why

yacli-shared 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 1mo 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.

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.
