Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00030 | $0.00895 |
| Opus 5.5 | $0.00012 | $0.00358 |
| Sonnet 5.5 | $0.00006 | $0.00179 |
| Haiku 4.5 | $0.00003 | $0.00089 |
Grade A, and why
google-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 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.
How it starts
The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Google Calendar via API
Direct Google Calendar API v3 integration. Replaces the old Apple Calendar/osascript approach (Mac-only).
Available Calendars
| Calendar | Calendar ID | Use for |
|---|---|---|
| Primary | primary |
Akash's default personal events |
| Work | work (or the actual calendar ID) |
Work meetings, blocks, focus time |
| Akash & Abhigna | (shared calendar ID from env) | Joint events: trips, date nights, shared appointments |
Set
GCAL_WORK_IDandGCAL_SHARED_IDin.envfor non-primary calendars.
Routing Rules
- Joint event (both Akash and Abhigna) → Akash & Abhigna (shared calendar)
- Work meeting / focus block → Work
- Akash personal → Primary
- If unsure and involves Abhigna → Akash & Abhigna

Optional flags:
--location "Restaurant Name, Berlin"--description "Notes about the event"--all-day(omit --time and --duration for all-day events)

--title "Updated Title" \
--time "15:00" \

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.

Other skills, from other repositories
telegram-userbot
A skill for connecting to and working through the owner's personal Telegram account, rather than a Telegram bot. It can read personal chats, search messages, and send messages as the account owner after setup and consent.
insight
A scheduled daily practice that looks for a repeated manual task, builds and tests a small tool for it, and suggests the result. It can instead report a development issue when the agent cannot solve its own problem.
watch
A monitoring and briefing workflow that checks unread Telegram messages, email, failed checks, and failed scheduled units, then decides what needs the owner's attention. It can also explain actions such as creating a task, delaying a reminder, ignoring an item, or fixing a failure.
brief
Brief — the owner's day in review: tasks, calendar, mail, Telegram, every Connection and plugin, goals from CORE, weather. Load in a scheduled Brief turn, on /digest, and when the owner asks for a day plan, a review of the day or their open tasks.
scheduling
A scheduling tool for creating reminders and recurring tasks, or running commands at set times. It can list, move, cancel, and immediately run scheduled items.
