gws-calendar-insert

A Google Calendar command for creating an event with a title, start and end times, and optional details such as attendees, a location, or a Google Meet link.

In plain words
What is it for?
Create meetings, appointments, and reminders in a selected calendar, including events with invitees or video calls.
Why use it?
It avoids opening Calendar and filling in the same event fields by hand. It also makes event creation repeatable from a command.

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

gws-calendar-insert 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 3d 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.

gws calendar +insert --summary 'Review' --start ... --end ... --attendee [email protected]
gws calendar +insert --summary 'Meet' --start ... --end ... --meet

Tips

  • Use RFC3339 format for times (e.g. 2026-06-17T09:00:00-07:00).
  • The --meet flag automatically adds a Google Meet link to the event.

[!CAUTION] This is a write command — confirm with the user before executing.

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.
