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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds one genuine behavioral fact — a stay can belong to multiple lifestyle categories — but says nothing about result ordering, pagination, or what happens when a category matches nothing.

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 short sentences, front-loaded with the verb and resource, with no filler or repetition of the tool name. The second sentence is brief and informative, though marginally less essential than the first.

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?

With only 2 fully documented params and annotations carrying the safety profile, the definition is nearly self-sufficient. However, there is no output schema, so the description should say a bit more about the shape of the returned stays (fields, ordering, paging) than the bare phrase 'Returns stays'.

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 description coverage is 100%: the schema already documents the default limit of 15 and the partial-match semantics of 'lifestyle', and even points to getAllLifestyles. The description only restates the same example categories, adding no syntax or matching detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb (Returns), resource (stays from the NomadStays database), and the exact filter facet (lifestyle/genre category) with concrete examples. The lifestyle facet inherently distinguishes it from the many getStaysBy* siblings (byAmenities, byBudget, byCountry, byWiFiSpeed), so an agent can route correctly 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?

The description gives no when-to-use or when-not-to-use guidance and names no alternative among the getStaysBy* family. The only routing hint ('Use getAllLifestyles tool to see all available categories') lives in the input schema, not the description, so usage must be inferred from the purpose alone.

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