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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so safety is covered. The description adds substantial behavior beyond that: proximity-based ranking from lat/lon, forums returning forum topics instead of places, domain controlling result language, offset pagination, and no output schema means its return-shape description (places/forums/locations/pagination) carries real weight.

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 paragraphs, front-loaded with the core action before return shape and enrichment pointers. The sentences are long and dense, and a few clauses (such as the generic 'build travel and hospitality datasets' remark) are close to filler, but overall little is wasted.

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 no output schema, the description takes on the job of explaining the return payload and does so thoroughly, naming each top-level field group and noting the pagination next offset. It also flags the domain's language effect and the offset ceiling, leaving no significant gap for a 7-parameter read-only search.

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%, so every parameter is already documented including examples, enum meanings and the 1000-offset cap. The description restates the parameter set (coordinates, type filter, domain, offset) without adding syntax or edge-case guidance beyond the schema, so 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 and resource ('Runs a Tripadvisor search for a free-text query') and enumerates the query shapes it accepts (destination, property name, listing-style phrase). It also implicitly separates itself from the detail endpoints by explaining that each place carries a hasdataLink that calls the Tripadvisor Place API for full details.

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?

Gives clear context for when to reach for this tool (free-text discovery of places/destinations/forums) and routes follow-up enrichment to the Place API via hasdataLink. It stops short of explicitly naming the sibling tools or stating when not to use this search (e.g., when only reviews or a known place ID are needed).

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