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

Annotations declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is already known. The description adds bulk execution capability, which is extra context but does not contradict annotations. No mention of additional behavioral traits like rate limits or side effects, but given the annotation coverage, this is acceptable.

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 two sentences with no fluff. It front-loads the primary action and then adds the important OData and bulk notes. Every word earns its place.

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?

For a read-only get-by-ID tool with OData options, the description is adequate. It covers the main use case and mentions bulk support. It lacks details on return format, but no output schema is provided, and for a GET this is often predictable. Given the schema has 5 parameters, a bit more parameter explanation would improve completeness, but it's still sufficient for a competent agent.

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 0%, so the description must compensate. It explains 'id' and 'ids' for bulk, and mentions $expand for sub-records, but does not describe 'query' or '$select'. These are common OData parameters and likely self-explanatory, but the description misses the opportunity to clarify their role in this specific tool.

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 clearly states the function: 'Busca um(a) Áreas de atuação por id' (searches an area of practice by ID) and gives the OData path /Areas/{id}. This distinguishes it from list and other get tools, and the verb+resource is specific.

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?

It provides usage context by mentioning $expand for sub-resources and bulk support for batched execution via ids. It does not explicitly contrast with list tools, but the purpose is clear enough that an agent can infer when to use it. Lacks explicit when-not-to-use guidance.

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