Scored across 1 tool
The server exposes exactly one tool, so there is nothing to confuse or misselect within the set. The description is explicit about what it does and even points elsewhere (google_flights_search) for filters/currencies, which reduces overlap ambiguity rather than creating it.
The single name `skyscanner_search_flights` follows a clear service_verb_noun snake_case convention with no casing or style deviations. Trivially consistent as a one-tool surface.
One tool is thin for a flight-search domain that typically needs airport/place resolution, flexible date or calendar search, multi-city, and filtering. The single tool itself is rich and well-scoped, but the surface feels under-provisioned rather than minimal-and-complete.
For a read-only fares lookup, the tool covers the core lifecycle: search one-way or round trip, return best/cheapest/fastest summaries, full itinerary detail, and a booking link. Remaining gaps are explicitly deferred to a sibling server, so no dead ends.

Search live Skyscanner (skyscanner.pl) fares for a one-way or round trip: the itineraries Skyscanner ranks best — total price in PLN, airlines, per-leg local times, duration, stops, self-transfer flag and a booking link — plus the cheapest and fastest fare across the whole search. The results page is rendered live through a paid unblocker, so a call takes ~20–40 s; finished searches are cached for 5 minutes. search_complete: false means Skyscanner was still collecting prices when the page was captured (calling again usually returns the finished search). For stop/time/airline filters or other currencies use google_flights_search. Result shape: { source, fetched_at, query, trip_type, search_url, currency, search_complete, providers_checked, providers_total, total_results, summary: { best, cheapest, fastest } (each { price_per_person, duration_minutes }), count, itineraries: [...], note } — the list key is itineraries, never flights or results. Each itinerary: { price, price_per_person, currency, airlines, legs: [...], self_transfer, offers_count, url }; each leg: { origin, origin_name, destination, destination_name, departure, arrival, duration_minutes, stops, stopovers, airlines, change_airport }. price is a number — the total for all passengers and both directions, taxes included; price_per_person is the fare per passenger; departure/arrival are local times 'YYYY-MM-DDTHH:MM'; a round trip has two legs (outbound, then return) under one price.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and does so well: ~20–40 s latency, a paid unblocker behind live rendering, 5-minute result caching, and the meaning of `search_complete: false` with its recovery action. Price semantics (total incl. taxes vs per-person) and local-time formatting are also disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Front-loaded and readable, but the bulk is an exhaustive enumeration of the result object (itinerary, leg, price, departure/arrival fields) that duplicates the existing output schema. The 'list key is `itineraries`, never `flights` or `results`' hint only earns its place if the output schema is loose; otherwise it is filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
A complex live-scrape tool with an output schema, and the description still covers latency, caching, partial-result semantics and price interpretation — everything an agent needs to call it correctly and interpret a call that looks thin.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so all seven parameters are already documented (IATA/city codes, date patterns, cabin enum, adults range, no_cache). The description adds no parameter-level meaning beyond the schema and instead spends its words on return shape — baseline 3 is correct.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Specific verb + resource + scope: 'Search live Skyscanner (skyscanner.pl) fares for a one-way or round trip,' and it names the concrete outputs (itineraries, best/cheapest/fastest summary). It also names the sibling it is not for filtered search, so an agent can distinguish without opening a schema.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit routing guidance: 'For stop/time/airline filters or other currencies use google_flights_search,' plus the one-way vs round-trip condition ('Omit return_date for one-way' via schema) and retry guidance for `search_complete: false`. It also warns about the 5-minute cache and how to bypass it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
