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 | $0.00066 | $0.00332 |
| Opus 5.5 | $0.00026 | $0.00133 |
| Sonnet 5.5 | $0.00013 | $0.00066 |
| Haiku 4.5 | $0.00007 | $0.00033 |
Grade A, and why
empty-legs 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.
What it actually says
SkyAccess private jet empty legs
Use the skyaccess MCP server for private jet flights, empty legs and private jet charter prices.
search_empty_legs,get_flight,booking_handoffandget_charter_estimateare read-only.search_empty_legstakes optionalorigin,destination,departureDateFrom,departureDateTo,passengersandmax_price(USD), and returns up to 5 flights. Inventory changes all the time, so search again rather than reusing old results.- Prices are for the whole aircraft, in USD. Taxes and fees are shown at checkout.
- A flight with
price: nullhas no published price; SkyAccess shows it as "Contact for price". get_charter_estimategives an indicative range for a full charter, not a quote.- To book, give the traveler the link from
booking_handoff. The traveler reviews and books on the SkyAccess page. - Call
request_bookingonly when the traveler asks SkyAccess to contact them and has given a name and email. It sends those details and the trip to SkyAccess, and a specialist replies by email. It takes no payment and creates no booking.
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.

empty-legs is a skill published in the GitHub repository sky-access/skyaccess-mcp (1 stars, last pushed 11d ago), licensed MIT.
