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 | $0.00064 | $0.00382 |
| Opus 5.5 | $0.00026 | $0.00153 |
| Sonnet 5.5 | $0.00013 | $0.00076 |
| Haiku 4.5 | $0.00006 | $0.00038 |
Grade A, and why
quick-event 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 1mo 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
Quick Event Creation
Parse the user's natural language input and create a calendar event.
Process
- Parse input: Extract title, date, time, duration, location from user's request
- List calendars: Show available calendars if not specified
- Check conflicts: Verify the time slot is available
- Create event: Use
create_eventwith proper ISO8601 datetime format
Examples
User: "Meeting with John tomorrow at 2pm for 1 hour" → Parse: title="Meeting with John", date=tomorrow, start=14:00, duration=1h → Create: start_time="2026-01-19T14:00:00+08:00", end_time="2026-01-19T15:00:00+08:00"
User: "Dentist on Friday 10am at 123 Main St" → Parse: title="Dentist", date=Friday, start=10:00, location="123 Main St" → Create with location parameter
Important
- Always confirm the calendar to use if user hasn't specified
- Default event duration: 1 hour if not specified
- Always use local timezone (e.g., +08:00 for Taiwan)
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.
