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

No annotations are provided, so the description carries the full burden. It usefully discloses the quality gate (publicly active, real name, 50+ char description) and that results are 'sanitized public listings', which is real behavioral context, but it is silent on pagination, result ordering, auth requirements, and empty-result behavior.

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?

Three tight sentences: purpose first, payload second, filtering rule third. No filler, no repetition, and each sentence adds information an agent can act on.

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 compensates by enumerating returned fields and the quality filter, and the schema documents all four parameters. It stops short of explaining paging/ordering behavior, which is the only notable gap for a paginated search tool.

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%, and the schema already provides examples for q and category and a default/range for limit. The description restates 'keyword and/or category' without adding format, matching, or ordering semantics 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?

The description gives a specific verb and resource ('Search BostonVacay business listings') plus the two facets it searches by (keyword and/or category), so its function is unambiguous. It does not explicitly differentiate itself from the sibling list_categories, which is the only thing keeping it from a 5.

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 'by keyword and/or category' phrasing implies how the tool is driven, but there is no explicit when-to-use or when-to-prefer-list_categories guidance, and with zero required parameters the agent gets no signal about valid minimal usage. Usage is inferable but not stated.

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