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 | $0.00023 | $0.00653 |
| Opus 5 | $0.00012 | $0.00327 |
| Sonnet 5 | $0.00005 | $0.00131 |
| Haiku 4.5 | $0.00002 | $0.00065 |
Grade A, and why
aviationstack 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 11d 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Aviationstack — Live Flight Tracker
Live gate, terminal, delay, and baggage-belt data for any flight, by IATA flight number or airport.
When to use
Reach for this whenever the user asks about the live status of a flight — gate, terminal, boarding, delay, landing, or which belt the baggage is on. Resolve the IATA flight number from context (itinerary, a forwarded confirmation, a screenshot) when you can, so you don't have to ask the user for it.
| User asks | You do |
|---|---|
| gate / terminal / boarding | flight <IATA> → departure.terminal, departure.gate, departure.delay |
| landed / touched down | flight <IATA> → status LANDED + arrival.actual |
| luggage / baggage belt | flight <IATA> → arrival.baggage (belt number) |
| delay / on time | flight <IATA> → departure.delay (0 = on time ✓) |
Example questions
| You ask | You run |
|---|---|
| "Which baggage belt is the luggage from flight LY574 coming out on?" | flight LY574 → arrival.baggage |
| "Is flight IZ212 departing on time, or is it delayed?" | flight IZ212 → departure.delay (0 = on time ✓) |
| "Where do I pick up my bags — which carousel?" | flight <IATA> → arrival.baggage |
| "Has flight AA100 landed yet?" | flight AA100 → status + arrival.actual |
Usage
python live_flight_tracker.py flight LY8 # today (the only reliable mode on free tier)
python live_flight_tracker.py airport TLV dep
python live_flight_tracker.py airport MIA arr active
The flight command takes an optional [YYYY-MM-DD], but a date other than today needs a
paid aviationstack plan — on the free key it returns "No data found". Track each flight
on its travel day, not in advance.

Notes
- Free tier: same-day real-time only, HTTP, 100 req/month — one call per question, never poll.
- Gate and baggage belt can change — always fetch live.
- Requires
AVIATIONSTACK_API_KEYin the environment. Note: the free tier is HTTP-only, so the key travels unencrypted in the request URL.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
