Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00033 | $0.02492 |
| Opus 5 | $0.00016 | $0.01246 |
| Sonnet 5 | $0.00007 | $0.00498 |
| Haiku 4.5 | $0.00003 | $0.00249 |
Grade A, and why
office:calendar-management 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.

Calendar Management with Office Admin
When to Use This Skill
Use this skill when:
- Adding events from emails
- Checking for scheduling conflicts
- Creating calendar holds for tentative events
- Converting timezones for international contacts
- Managing working hours and availability
- Blocking focus time or recurring events
User Calendar Preferences
Load preferences from ~/.claude/office-admin-config.json:
{
"personal": {
"timezone": "America/Chicago",
"workingHours": {
"start": "09:30",
"end": "16:30",
"lunchStart": "12:00",
"lunchEnd": "13:30"
}
},
"calendar": {
"defaultDuration": 30,
"bufferMinutes": 15,
"schedulingLink": "https://user.cal.com/schedule",
"autoAddFromEmail": true,
"eventNaming": {
"includeLocation": true,
"includeAttendees": false
}
}
}
Core Principles
- Always check conflicts first - Before committing to an event
- Respect working hours - Use user's configured schedule
- Handle timezones carefully - Convert accurately, show both zones
- Be proactive - Auto-add events from emails when configured
- Use descriptive titles - Include location/context per user preference
Adding Events from Emails
Step 1: Extract Event Details
Look for in the email:
- Date and time (or phrases like "tomorrow", "next Tuesday", "in two weeks")
- Duration (or use defaultDuration from config)
- Location (physical address, restaurant name, virtual link)
- Event type (meeting, lunch, coffee, party, etc.)
- Attendees (who else is invited)
- Special notes (dress code, what to bring, etc.)
Step 2: Parse Relative Dates
Handle conversational dates:
- "tomorrow" → current date + 1 day
- "next Monday" → next occurrence of Monday
- "in two weeks" → current date + 14 days
- "Dec 5" → December 5 of current year (or next if passed)
Step 3: Check Calendar for Conflicts
BEFORE creating the event:
# Get user's calendar for that date
mcp__pd__google_calendar-list-events(
instruction="Get all events for [date], between [start_time - bufferMinutes] and [end_time + bufferMinutes]"
)
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.
