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

Annotations already declare readOnlyHint=true and idempotentHint=true, indicating a safe read operation. The description adds that it accepts bulk IDs for batched execution, which is beyond the annotations. No contradictions.

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 very brief (two sentences) and front-loaded with the main purpose. It wastes no words, but the lack of parameter detail is a minor trade-off.

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?

Given no output schema, the description should explain return values, but it doesn't. Bulk support is mentioned, but parameter semantics for 'query' and 'account' are missing. It's adequate for a simple GET but incomplete for a 4-parameter tool with no output schema.

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 0%, so the description must explain parameters, but it only mentions 'ids' for bulk. The 'id', 'query', and 'account' parameters are not described at all, leaving the agent to guess their meaning. The description adds minimal value beyond 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?

The description clearly states 'Buscar produto' (search/get product) and provides the exact endpoint GET /api/v1/products/{id}. It distinguishes this from list/create/update/delete siblings by indicating it's a retrieval operation.

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 notes bulk support via IDs, which hints at when to use this over list. However, it does not explicitly state when to use this vs. datacrazy_products_list (e.g., when you have a specific ID vs. need to list all). No exclusion guidance is provided.

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