A Google Calendar connection for managing your schedule from Telegram, a messaging app. It can read, create, change, and remove events, and provide daily briefings or reminders.

Check upcoming events, find free time, schedule meetings, update or delete events, and receive daily schedule summaries or reminders.

It removes the need to switch between Telegram and Google Calendar for routine scheduling tasks. It can also clarify when you are available and ask for confirmation when details are unclear.

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	$0.00055	$0.00792
Opus 5	$0.00028	$0.00396
Sonnet 5	$0.00011	$0.00158
Haiku 4.5	$0.00006	$0.00079

Security

Grade A, and why

calendar 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 11d 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 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.
