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 | $0.00009 | $0.00369 |
| Opus 5.5 | $0.00004 | $0.00148 |
| Sonnet 5.5 | $0.00002 | $0.00074 |
| Haiku 4.5 | $0.00001 | $0.00037 |
Grade A, and why
remind 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 13d 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 Reminder Creation
Create a reminder from the user's natural language input.
Process
- Parse input: Extract task title, due date/time, priority. If the user gives a date but no time, pass a bare date (
2026-01-19): that makes a date-only reminder, with no time (#267) - Get reminder lists: Use
list_calendarswith type="reminder" if needed - Create reminder: Use
create_reminder
Examples
User: "Remind me to buy milk" → create_reminder(title="Buy milk", calendar_name="Reminders")
User: "Call mom tomorrow at 5pm" → create_reminder(title="Call mom", due_date="2026-01-19T17:00:00+08:00", calendar_name="Reminders")
User: "Pay rent on the 18th" → create_reminder(title="Pay rent", due_date="2026-01-18", calendar_name="Reminders") (date-only: no time)
User: "Submit report by Friday - high priority" → create_reminder(title="Submit report", due_date="...", priority=1, calendar_name="Reminders")
Priority Values
- 1 = High priority
- 5 = Medium priority
- 9 = Low priority
- 0 = No priority (default)
Tips
- Ask user for reminder list if they have multiple
- Default to "Reminders" list if not specified
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.
