Browse & filter offers (advisor, one call)

charter_offers
Read-onlyIdempotent

THE discovery tool: filters the whole cached charter inventory (hundreds of hotels) in ONE call by date, TOTAL budget, stars, board, zone, party and hotel features (aquapark, kids club, adults-only, beach, spa, luxury…). Built for "I have X EUR for 2 adults + a child, Antalya, 5 stars, aquapark, near the beach — what do you suggest?". Returns the price range, three quality tiers (economy-but-good / mid / premium) and a shortlist; advise from the tiers, never only the cheapest. Pass the date whenever the user has one (exact availability for that date) and the real party (exact-party cache is used when present). excluded_unknown_features tells how many hotels were dropped because their facilities are unknown. CACHED prices (from recent real searches on flytravel.al — not a live query; every row carries cached_at/age_minutes). Charter prices are PACKAGE TOTALS in EUR for the row's "party" (flight + hotel + transfers), NOT per person. party_match=false means the price is the 2-adult reference, not the total for the requested party — say so. A price belongs ONLY to its own "date": never present it as the price of another date.

boardNoBoard filter substring, e.g. 'all inclusive', 'ultra'.
limitNoShortlist size (default 12).
adultsNoNumber of adults (default 2).
luxuryNotrue = only hotels tagged luxury.
nightsNoTrip length in nights. Omit for the standard charter length (6 nights / 7 days). Most departures also sell 3-10 nights.

destinationNoOptional destination key ('antalya', 'bodrum'). Omit to search all.
children_agesNoAge of each child AT DEPARTURE (0-14 = child; 15+ is counted as an adult automatically).
private_beachNotrue = only hotels listing a private / own beach.
family_friendlyNotrue = only hotels with family facilities (kids club / kids pool / family rooms) and not adults-only.

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description is rich with behavioral caveats beyond the read-only annotations: prices are cached, not live; prices are package totals in EUR, not per person; party_match=false means the price is a 2-adult reference; and a price belongs only to its own date. It also explains excluded_unknown_features. This is essential for the agent not to misrepresent results.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but every sentence earns its place: it front-loads the core purpose, then adds a concrete example, then the output structure, then essential caveats about cache, pricing, and date-bounding. There is no filler or restating of schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description takes on the burden of explaining what the tool returns: price range, three quality tiers, a shortlist, excluded_unknown_features, and party_match semantics. It covers the necessary context for an agent to call and interpret results correctly, even for a complex 19-parameter tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already documents all 19 parameters well. The description adds some context about party-exact cache usage and not presenting prices across dates, but these are largely behavioral rather than new parameter-level semantics. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb+resource: it filters the whole cached charter inventory in one call by multiple criteria. It clearly differentiates itself from siblings by positioning itself as the discovery tool with an illustrative natural-language query, and by mentioning the one-call nature.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context on when to use the tool: for open-ended 'what do you suggest' queries, and instructs to pass the date and real party when available. It does not explicitly mention alternatives or exclusions, so it stops short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
