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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description adds context the annotations do not: filters are case-insensitive, supplier profile links are included only 'when available', and booth assignments are advisory and should be verified. That is genuine disclosure beyond structured fields.

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 verb+resource is front-loaded so the agent learns the operation immediately. The trailing statements about case-insensitivity and booth confirmation are compact, though they could be tightened.

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 and 5 parameters, the description carries more burden than it does: it hints at supplier profile links and paging but never outlines the returned booth fields or pagination limits. Combined with 40% schema coverage on parameters, the definition is adequate but leaves real gaps for a list/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 only 40%: query and category are documented in the schema, but page, limit, and event_slug carry no descriptions. The description partially compensates by establishing case-insensitive semantics for category and name filtering, but it says nothing about page/limit behavior, which must be inferred from defaults and min/max in the schema.

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 set (filter and page) plus a precise resource (an event's published exhibitor booths), which clearly separates it from siblings like search_suppliers, get_supplier, and list_events. It does not explicitly name an alternative tool, so it stops short of a 5, but an agent can identify the resource unambiguously.

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 when-to-use or when-not-to-use guidance, and no routing to alternatives such as search_suppliers or get_supplier even though the description mentions supplier profile links. The only advisory sentence ('booth assignments should be confirmed with the exhibitor') is a data-accuracy caveat, not usage guidance.

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