Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **PREREQUISITE:** Read `../gws-shared/SKILL.md` for auth, global flags, and security rules. If missing, run `gws generate-skills` to create it..

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 9d 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 <TEXT> --start <TIME> --end <TIME>

Flags

Flag Required Default Description
--calendar primary Calendar ID (default: primary)
--summary Event summary/title
--start Start time (ISO 8601, e.g., 2024-01-01T10:00:00Z)
--end End time (ISO 8601)
--location Event location
--description Event description/body
--attendee Attendee email (can be used multiple times)

gws calendar +insert --summary 'Standup' --start '2026-06-17T09:00:00-07:00' --end '2026-06-17T09:30:00-07:00'
gws calendar +insert --summary 'Review' --start ... --end ... --attendee [email protected]

Tips

  • Use RFC3339 format for times (e.g. 2026-06-17T09:00:00-07:00).
  • For recurring events or conference links, use the raw API instead.

[!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.
