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 | $0.00058 | $0.02900 |
| Opus 5 | $0.00029 | $0.01450 |
| Sonnet 5 | $0.00012 | $0.00580 |
| Haiku 4.5 | $0.00006 | $0.00290 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 408 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Automate Google Calendar operations including listing events, checking availability, creating meetings, and managing attendees. Particularly useful for sales teams scheduling calls, finding available slots to propose to clients, and managing recurring meetings.
Google Calendar
Read, create, and manage Google Calendar events via OAuth authentication.
CRITICAL SAFETY RULES
These rules are MANDATORY and must NEVER be bypassed:
1. NEVER Create Events Without Explicit Approval
- ALWAYS show the user the complete event details before creating
- ALWAYS ask for explicit confirmation: "Create this event? (yes/no)"
- NEVER auto-create events, even if user says "schedule a meeting"
- NEVER create multiple events in a loop without per-event confirmation
2. Calendar Invites Alert Attendees
- When an event has attendees, creating/updating/deleting it sends notifications
- ALWAYS warn the user: "Attendees will receive a calendar invite!"
- Consider the impact before modifying events with external participants
3. Recurring Events Need Extra Care
- Modifying a recurring event can affect all instances
- WARN user when working with recurring events
- Ask whether to modify single instance or all occurrences
4. Confirm Deletions
- ALWAYS show event details before deleting
- If event has attendees: "Attendees will be notified of cancellation"
- REQUIRE explicit confirmation before delete
5. Safe Operations (No Confirmation Needed)
These do NOT require confirmation:
- List events
- Get event details
- List calendars
- Search events
- Check availability (freebusy)
- Find available slots
Pre-Flight Check (ALWAYS RUN FIRST)
uv run python 00-system/skills/google/google-master/scripts/google_auth.py --check --service calendar
Exit codes:
- 0: Ready to use - proceed with user request
- 1: Need to login - run
python3 00-system/skills/google/google-master/scripts/google_auth.py --login - 2: Missing credentials or dependencies - see ../google-master/references/setup-guide.md
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

google-calendar is a skill published in the GitHub repository DorianSchlede/nexus-template (8 stars, last pushed 7mo ago), licensed MIT. It adds 58 tokens to every session and 2,900 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
