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

gw-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.

How it starts

The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Calendar

Account

Events are created on the default account unless you pass --account <name>. The default account is configurable — run gw auth list to see the accounts you have set up, and pass --account <name> to target a specific one.

Required Fields — always populate

Every create and update MUST include ALL of these fields. Never create a partial event.

Field Flag Default
Title --title — (required)
Start time --start — (required)
Duration --duration 30 min
Description --description
Location --location
Attendees --attendees
Reminders --reminders 60,30,10 (auto)
Meet link --meet only when virtual

If the request is missing any of these details:

  1. Search email first. Use the gmail skill to find the relevant thread:
    $CLI gmail list --query "subject:KEYWORD" --limit 5 --compact
    $CLI gmail get MESSAGE_ID --compact
    
    Extract: location/address, attendees, agenda/description, time details.
  2. If email doesn't have it, ask the user. Do not guess or leave fields blank.

Examples of what to look for:

  • "Let's meet at the office" → search email for the address, use as --location.
  • "Call with Alex" → search email for Alex's email, full name for title, any agenda for description.
  • "Coffee with investor" → search email for venue name + address, attendee email.
  • In-person → --location with full address. Virtual → --meet flag. Hybrid → both.
  • Workspace may auto-attach a Meet link on any event write (account "Automatically add Google Meet" setting), so an in-person event can sprout one after an unrelated update. That's not a bug. Pass --meet false to strip it (the CLI sends conferenceDataVersion=1, required for removal to take effect).

Defaults (auto-applied)

  • Reminders: 60, 30, 10 min popup — set automatically on create. Do NOT change unless the user explicitly requests different reminders. Override: --reminders "120,15".
  • Duration: 30 minutes.

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.
