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

read-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 2mo 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 it actually says

Read Calendar

Retrieves calendar events from macOS Calendar for analysis, planning, and scheduling.

When to Use

  • "What's on my calendar today?"
  • "Show me my schedule for this week"
  • "Do I have any meetings tomorrow?"
  • "What's my next meeting?"

Requirements

This skill requires icalBuddy to properly handle recurring events: ```bash brew install ical-buddy ```

Instructions

Execute Calendar Read

Use icalBuddy to retrieve events including recurring ones:

```bash icalBuddy -n -iep "title,datetime,location" -df "%Y-%m-%d" -tf "%H:%M" eventsFrom:<start_date> to:<end_date> ```

Example: ```bash icalBuddy -n -iep "title,datetime,location" -df "%Y-%m-%d" -tf "%H:%M" eventsFrom:2025-10-26 to:2025-10-27 ```

Note: icalBuddy properly handles recurring events (unlike AppleScript which doesn't pre-generate future instances).

Present Results

Format events clearly:

  • Group by day
  • Show time, title, location, calendar name
  • Highlight conflicts if any
  • Identify gaps for focus time
  • Mark recurring events clearly

What ships with it

3 files 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.

Changes

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.
