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

Annotations already provide readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds useful context about the supported categories and default-radius behavior through schema. It does not disclose response pagination, unavailability of certain categories, or cutoff ranges, so it adds some but not rich behavioral context. With annotations covering the core traits, a 3 is fair.

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?

The description is focused and front-loaded with the core action, followed by the return fields, then usage examples, then supported categories. Every sentence contributes something useful, with no redundant restatement of the tool name or title.

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?

Annotations cover safety and idempotence, the schema covers all three parameters, and the description covers scope, return fields, examples, and category list. The main gap is lack of explicit mention of result limits or fallback behavior for unknown locations, but for a read-only local discovery tool this is adequate and nearly complete.

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 100%, so each parameter is already documented. The description adds practical value by listing the output fields and many example query strings, but it does not deepen the meaning of the parameters beyond the schema. Baseline 3 is appropriate since the schema carries the semantic load.

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 uses a specific verb ('Find') plus a clear resource ('local businesses, restaurants, services, and places near any location') and enumerates return fields. It distinguishes itself from the large sibling set by naming the exact query patterns it serves, so an agent can immediately recognize what it does.

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 many concrete example queries and explicitly says 'Use this for... or any local business or place discovery question.' It does not name sibling alternatives like recreation_nearby or realestate_search to exclude, but the examples plus 'any local discovery' provide strong practical guidance for when to select it.

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