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 | $0.00022 | $0.00451 |
| Opus 5 | $0.00011 | $0.00226 |
| Sonnet 5 | $0.00004 | $0.00090 |
| Haiku 4.5 | $0.00002 | $0.00045 |
Grade A, and why
email-scheduling 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 3d 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
Email-Based Meeting Scheduling
Workflow
1. Parse Email Requests
Extract from each email:
- Duration: e.g., "one-hour", "1.5 hour", "45-minute"
- Date constraint: e.g., "March 9th, 2026"
- Time window: e.g., "10:00am to 2:00pm", "1:00 PM and 5:00 PM PST"
- Sender email: from the
from_emailfield
2. Timezone Conversion
- If the request specifies a timezone different from the calendar, convert:
- PST to ET: add 3 hours (e.g., 1:00 PM PST = 4:00 PM ET)
- CST to ET: add 1 hour
- MST to ET: add 2 hours
3. Scheduling Strategy
- Find the earliest available slot that satisfies all constraints
- When multiple requests target the same day, schedule them so all can be accommodated
- Blue (low-priority) calendar blocks can be overwritten
- Never overlap with non-overwritable blocks
4. Reply Template Format
Hi,
Thank you for your meeting request.
I can be available:
Date: {day_name}, {month} {DD}, {YYYY}
Time: {HH:MM AM/PM} - {HH:MM AM/PM}
Duration: {meetingDuration} hour(s)
If this time doesn't work, please let me know your preferred alternatives.
Best regards,
ConSkillBench
5. Formatting Rules
- Date:
Monday, March 09, 2026(zero-padded day, full month name) - Time:
09:00 AM - 10:30 AM(zero-padded hours, AM/PM with space) - Duration: use "hour(s)" as unit; for 45 min use "0.75 hour(s)"
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.

email-scheduling is a skill published in the GitHub repository cxcscmu/SkillLearnBench (83 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 451 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
