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 | $0.00048 | $0.01838 |
| Opus 5 | $0.00024 | $0.00919 |
| Sonnet 5 | $0.00010 | $0.00368 |
| Haiku 4.5 | $0.00005 | $0.00184 |
Grade A, and why
premium-hotels 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.
How it starts
The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Premium Hotel Programs
Search 4,659 premium hotel properties across three credit card programs. Find which hotels offer complimentary benefits, compare credits, and identify stacking opportunities where a hotel appears in multiple programs.
No API key needed. All data is local JSON files in data/.
When to Use
- User asks "what FHR hotels are in Stockholm?"
- Comparing hotel options for a trip and want to maximize card benefits
- Looking for hotels where Amex FHR + Chase Edit credits stack
- Checking if a specific hotel is in any premium program
Programs
| Program | Card Required | Key Benefits | Properties |
|---|---|---|---|
| FHR (Fine Hotels & Resorts) | Amex Platinum | $100+ property credit, room upgrade, noon check-in, 4pm checkout, daily breakfast for 2, complimentary wifi | 1,807 |
| THC (The Hotel Collection) | Amex Platinum | $100 property credit on 2+ night stays for dining/spa/resort activities | 1,299 |
| Chase Edit (Sapphire Hotel Collection) | Chase Sapphire Reserve | $50 annual hotel credit, elevated experience perks. Select Hotels add $250 one-time 2026 credit + 10x points. | 1,553 |
Stacking
Hotels in BOTH FHR/THC AND Chase Edit can stack benefits. Book through one program and use the other card's credits separately. Look for hotels that appear in multiple programs.
Searching by City
FHR and THC (coordinate-based)
FHR and THC properties have lat/lng coordinates. Search by bounding box around a city.
Find properties near a city (adjust lat/lng and radius as needed):
# Stockholm (59.33, 18.07) - search within ~0.15 degrees (~15km)
LAT=59.33; LNG=18.07; R=0.15
jq --argjson lat $LAT --argjson lng $LNG --argjson r $R \
'[.properties[] | select(
.coordinates.lat > ($lat - $r) and .coordinates.lat < ($lat + $r) and
.coordinates.lng > ($lng - $r) and .coordinates.lng < ($lng + $r)
) | {name, program, credit}]' data/fhr-properties.json
jq --argjson lat $LAT --argjson lng $LNG --argjson r $R \
'[.properties[] | select(
.coordinates.lat > ($lat - $r) and .coordinates.lat < ($lat + $r) and
.coordinates.lng > ($lng - $r) and .coordinates.lng < ($lng + $r)
) | {name, program, credit}]' data/thc-properties.json
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.

premium-hotels is a skill published in the GitHub repository bailylu/travel-hacking-toolkit (11 stars, last pushed 4mo ago), licensed MIT. It adds 48 tokens to every session and 1,838 once invoked, about $0.0002 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 2026-08-30.
