What is google-calendar-skill?

A Google Calendar interface for managing events and answering calendar questions. It supports separate authenticated accounts, such as personal and work calendars.

Use it to search, create, and update events, answer calendar queries, and manage multiple Google Calendar accounts.

It lets programs handle scheduling and calendar information without switching between calendars manually.

SkillSpector: 3 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Privilege Escalation · line 24
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Skill reads from agent configuration directories (.claude/, .codex/, .gemini/). These directories may contain API keys, personal settings, and other credentials that the skill has no legitimate need to access.

Fix: Remove all code or instructions that access agent configuration directories (.claude/, .codex/, .gemini/). If configuration values are needed, pass them explicitly as parameters or environment variabl
medium Rogue Agent · line 70
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.02015
Opus 5	$0.00018	$0.01007
Sonnet 5	$0.00007	$0.00403
Haiku 4.5	$0.00004	$0.00201

Security

Grade A, and why

google-calendar-skill 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.

The scan reads SKILL.md. This mod also ships 13 executable files (scripts/action-logger.js, scripts/auth/auth-utils.js, scripts/auth/setup-oauth.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Google Calendar Skill

This skill provides comprehensive Google Calendar integration through lightweight CLI scripts. All operations are token-efficient and composable.

First-Time Setup

Before using this skill, you must set up OAuth authentication:

Install dependencies:

cd ~/.claude/skills/google-calendar-skill && npm install

Set up Google Cloud credentials:
- Follow the guide in docs/google-cloud-setup.md
- Enable Google Calendar API
- Download credentials.json and save to scripts/auth/credentials.json

Authenticate:

cd ~/.claude/skills/google-calendar-skill && npm run setup

This will open a browser for Google OAuth and save your token locally.

Multi-Account Support

The Calendar skill supports multiple accounts (e.g., personal and work calendars):

Add Additional Accounts

# Add a second account (from skill directory)
npm run setup -- --account work

# Add a third account
npm run setup -- --account personal

Each account needs separate OAuth authentication.

Manage Accounts

# List all configured accounts
node scripts/manage-accounts.js --list

# Set default account (used when --account is not specified)
node scripts/manage-accounts.js --set-default work

# Remove an account
node scripts/manage-accounts.js --remove old-account

Using Specific Accounts

All Calendar operations support the --account parameter:

# List work calendar events
node calendar-events-list.js --account work --limit 10

# Create event on personal calendar (or omit --account to use default)
node calendar-events-create.js --account personal --summary "..." --start "..." --end "..."

# Search work calendar
node calendar-events-list.js --account work --query "team meeting"

If --account is not specified, the default account is used.

Usage Guidelines

1. Read Documentation On-Demand

When first using Calendar operations, read the comprehensive README:

cat ~/.claude/skills/google-calendar-skill/README.md
