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

Annotations already declare read-only, idempotent, and open-world behavior. The description adds valuable behavioral rules: do not fabricate values when parser_drift or sparse, and compact output is default. This goes beyond the structured hints and is consistent with them.

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?

Three terse sentences, with the core resource first, followed by the two operational caveats. No filler or restatement. The structure is efficient and scannable.

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?

The description covers the data source and important caveats, but it does not explain how the product id is provided given the empty schema, nor what the returned technical characteristics contain. There is no output schema to fill that gap and no usage guidance to disambiguate from sibling tools. For a no-parameter read tool, the lack of product-selection context is a meaningful hole.

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?

With zero parameters in the schema, the description has little formal parameter burden, but it references an {id} in the path and a compact default that do not appear in the input schema. This can confuse an agent about whether to supply an id or a compact flag. The description still conveys the endpoint and default behavior, so it is not entirely unhelpful.

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 identifies the resource as technical characteristics served from /product/characteristics/{id}/, and the title supplies the 'get' verb. It does not explicitly contrast with siblings like dns_product_details or dns_product_variants, but the endpoint and 'specifications' scope make the purpose unambiguous.

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 no guidance on when to prefer this tool over the many sibling tools. The only conditional ('When parser_drift or sparse') is a data-quality caveat, not a usage selector. This leaves an agent to infer the appropriate context from the name alone.

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