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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00101 | $0.02181 |
| Opus 5.5 | $0.00040 | $0.00872 |
| Sonnet 5.5 | $0.00020 | $0.00436 |
| Haiku 4.5 | $0.00010 | $0.00218 |
Grade A, and why
gardening 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.
How it starts
The opening of the file, as written. The whole thing — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reservation Gardening
Concept: "Gardening" (coined by Nicholas Kralev, popularized by View from the Wing) means regularly tending to your travel reservations — catching problems early and spotting opportunities to upgrade, rebook, or save money.
Reservations File
The user points this skill at a file containing their current bookings. The file path is provided when invoking the skill (e.g., ~/trips/reservations.json or ~/trips/reservations.yaml).
If no file path is provided, ask the user for it.
Expected File Format
The file should contain an array of reservations. Each reservation should include as much of the following as possible:
[
{
"trip_name": "Sydney Vacation",
"confirmation": "ABC123",
"type": "flight",
"booking_date": "2026-03-15",
"program": "United MileagePlus",
"paid_with": "points",
"cost": { "miles": 85000, "taxes_usd": 45.60 },
"cash_price_at_booking": 2340,
"segments": [
{
"airline": "UA",
"flight": "UA870",
"origin": "SFO",
"destination": "SYD",
"date": "2026-09-12",
"departure": "22:30",
"arrival": "07:15+2",
"cabin": "business",
"fare_class": "I",
"seat": "6A",
"aircraft": "787-9"
}
],
"passengers": 2,
"notes": "Booked with Chase UR transfer"
},
{
"trip_name": "Sydney Vacation",
"confirmation": "HTL-9876",
"type": "hotel",
"hotel_name": "Park Hyatt Sydney",
"program": "World of Hyatt",
"paid_with": "points",
"cost": { "points": 30000, "per_night": true },
"cash_price_at_booking": 850,
"checkin": "2026-09-14",
"checkout": "2026-09-18",
"room_type": "King Deluxe",
"guests": 2
}
]
Flexible on format — YAML, JSON, CSV, or even markdown tables are fine. Parse whatever is provided.
Gardening Checklist
For every reservation in the file, run through this checklist. Parallelize searches across reservations for speed.
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.
