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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00040 | $0.02668 |
| Opus 5.5 | $0.00016 | $0.01067 |
| Sonnet 5.5 | $0.00008 | $0.00534 |
| Haiku 4.5 | $0.00004 | $0.00267 |
Grade A, and why
compare-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 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 — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Companion reference skills. Load these for deeper context:
hotel-chains— branded property to loyalty program mappingpremium-hotels— FHR / THC / Chase Edit credits and stacking strategypoints-valuations— CPP floor/ceiling for hotel programs (Hyatt 1.4-1.7cpp, Hilton 0.4cpp floor, etc.)fallback-and-resilience— recovery when a hotel source fails
Compare Hotels
Search every available source for accommodation and present one unified comparison. Combines portal premium programs (Chase Edit, Amex FHR/THC), cash pricing, and Airbnb alternatives into a single view.
This is an orchestration skill. It tells the agent which tools to run and how to combine results. No standalone script.
When to Use
- "Find me a hotel in Paris for Aug 11-15"
- "Should I book through Chase or Amex for this hotel?"
- "Compare hotels vs Airbnb in Oslo"
- Any accommodation search where the user wants the full picture
Sources
Run these in parallel where possible. Never fail silently.
Portal Premium Programs (Docker required)
| Source | Skill | Speed | What It Finds |
|---|---|---|---|
| Chase Travel | chase-travel |
~45s | Edit hotels ($100 credit, breakfast, upgrade), Points Boost, standard hotels |
| Amex Travel | amex-travel |
~45s | FHR ($100+ credit, breakfast, upgrade, late checkout), THC ($100 credit on 2+ nights) |
Cash Prices and Metasearch
| Source | Skill/Tool | Speed | What It Finds |
|---|---|---|---|
| SerpAPI | serpapi |
~3s | Google Hotels cash prices and direct booking links. |
| Trivago | web search | ~5s | Metasearch across many OTAs. Use tavily/exa to search trivago.com. Finds the absolute cheapest OTA rate. |
| LiteAPI | web search | ~5s | Hotel API aggregator with negotiated rates. Check liteapi.travel. Can find rates below public OTA pricing. |
| RapidAPI | rapidapi |
~3s | Booking.com inventory and pricing. Optional, use when user asks for Booking.com specifically. |
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.
