.claude/skills/gws-calendar-agenda/SKILL.md

gws-calendar-agenda is a skill for Claude Code from djbelieny/nova. It costs 16 tokens per session (419 once invoked), scanned A, a copy of gws-calendar-agenda, MIT.

A read-only command for viewing upcoming events from your Google Calendar accounts. You can show events for today, tomorrow, this week, or a chosen number of days.

In plain words
What is it for?
Use it to inspect your schedule in scripts or from the command line, such as checking today’s meetings, this week’s events, or the next three days.
Why use it?
It saves you from opening Google Calendar and checking several calendars separately. It also lets you filter by calendar and use a specific time zone.

This is djbelieny/nova's own configuration. It tells Claude Code how to work on nova itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nova configures →

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-agenda 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 12d 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.
