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

Annotations already declare readOnlyHint and idempotentHint, so safety is covered, and the description adds real value by naming the returned fields and asserting result parity and ordering with the pelikani.net search. It stops short of describing pagination behavior or how page/limit interact with the max bounds, which is the remaining behavioral gap for an 11-parameter search.

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?

Two tight sentences: the first states scope and the two modes, the second states exactly what comes back plus the ordering guarantee. Nothing is repeated from the schema and nothing is padding.

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?

For a zero-required-parameter search with no output schema, the description is nearly sufficient: it defines scope, currency, return fields and result ordering. It could still be more complete by clarifying pagination and the meaning of the sort enum, but nothing an agent needs to invoke the tool correctly is missing.

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 91%, so the schema already explains q, beds, city, page, type, baths, limit, status, min_price and max_price; the description only reinforces the EUR currency and the sell/rent meaning of status. The sort parameter has no description in either place, so the description does not compensate for the one real gap.

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?

The description gives a specific verb ('Search'), a precise resource ('public real-estate listings in Kosovo'), and the two supported intents ('for sale or for rent'). It also enumerates what each result carries (price in EUR, area in m², location, listing URL), which separates it cleanly from the single-record sibling get-listing.

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?

Usage is only implied: an agent can infer this is the browse/query tool and get-listing is the detail tool, but the description never says when to prefer one over the other, nor does it state any exclusions or preconditions. No guidance is given on whether filters combine or which ones matter most.

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