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

Annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=false, which covers the safety profile. The description adds nothing behavioral beyond that - no result format, ranking, or coverage notes - and the limit schema carries the one behavioral hint (don't probe with tiny samples).

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 with no filler and the core action front-loaded. The second sentence is arguably a distraction from invocation, but it doesn't bloat the definition.

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 an output schema present, return values need no explanation, but the definition still omits guidance on tags/category semantics and on how this tool relates to the other search_* siblings. For a 4-parameter search tool with 50% schema coverage, that leaves the agent under-equipped.

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 only 50%: 'limit' and 'query' are documented, but 'tags' and 'category' have no description in either the schema or the tool description. The description does not compensate for that gap at all, leaving two of four parameters semantically opaque.

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 ('Search Houston restaurant/coffee recommendations'), which is enough to place it among the many search_* siblings as the food-domain one. It doesn't explicitly differentiate itself from search_guide or search_events, so it falls short of 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?

There is no statement of when to use this tool versus siblings like search_guide, nor any prerequisites or exclusions. The only directive is to point users at an external URL, which is a routing suggestion rather than usage guidance for the agent.

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