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 | $0.00302 | $0.03281 |
| Opus 5 | $0.00151 | $0.01640 |
| Sonnet 5 | $0.00060 | $0.00656 |
| Haiku 4.5 | $0.00030 | $0.00328 |
Grade A, and why
trip-planner scanned grade A with 1 finding 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.

Trip Planner
Overview
This skill turns a fuzzy request like "a week in Rome in May under $2000" into two live searches — one round-trip flight search and one hotel search on the same dates — and one combined number the user can act on. Use travel-data-api for auth, base URL, and endpoint details. Prefer the hosted MCP tools when a client is configured — both legs are available over MCP: flights on flights.flightpowers.com/mcp, hotels on hotels.flightpowers.com/mcp, and both on the free server.
The fields you will actually read: from flights, total_price_as_number, total_price, buy_link, price_range_in_relation_to_other_periods, price_insights_low, price_insights_high, and the departure_flight_arrival_description / return_flight_departure_description strings that tell you which calendar day each end of the trip lands on. From hotels, properties[].name, price, price_string, review_score, review_count, room_type, location, and link, plus the echoed checkin_date, checkout_date, applied_filters, and budget_per_night.
This is an independent API that returns publicly available flight and hotel pricing; it is not affiliated with, endorsed by, or sponsored by Google or Booking.com.
Endpoints
| Leg | Endpoint / MCP tool |
|---|---|
| Round-trip flights | POST /api/google_flights/roundtrip/v1 on google-flights-live-api.p.rapidapi.com |
| Round-trip flights (MCP) | search_roundtrip_flights — takes departure_date_from/departure_date_to, a list of destinations, and nights |
| One-way legs (open-jaw) | POST /api/google_flights/oneway/v1 on google-flights-live-api.p.rapidapi.com |
| One-way legs (MCP) | search_oneway_flights — takes departure_date_from/departure_date_to and a list of destinations |
| Hotels for the stay | POST /search on booking-live-api.p.rapidapi.com — REST only, no MCP tool exists |
| One named hotel | POST /hotel_by_name on booking-live-api.p.rapidapi.com |
Workflow
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.

trip-planner is a skill published in the GitHub repository mtnrabi/travel-agent-skills (4 stars, last pushed 8d ago), licensed MIT. It adds 302 tokens to every session and 3,281 once invoked, about $0.0015 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
