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

No annotations are provided, so the description carries the burden of behavioral disclosure. It does disclose a pay-per-use cost on Base, which is valuable behavioral context, but it leaves output format, error behavior, and source-language handling implied only by the verb 'translate.'

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 compact and front-loaded: it states the operation, gives the exact input contract, and discloses pricing in one sentence. There is no filler or repetition.

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 single required string parameter, the description covers the input contract and cost. However, output behavior is left unspecified, no alternatives are mentioned, and since there is no output schema, some explicit return-value context would make the tool easier to invoke reliably.

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?

The schema already documents the 'input' parameter with a format label, but the description adds a concrete English example ('en | Hello world') and explains the target-language/text separation more clearly, especially because the schema description is written in Spanish.

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?

Description has a specific verb ('Translate'), a clear resource ('any language'), and a concrete input syntax. It likely stands apart from siblings like translate-en or translate-doc, but it does not explicitly name them, so it stops short of full differentiation.

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 guidance on when to use this tool versus alternatives such as translate-en, translate-doc, traducir, or detect-language. The phrase 'any language' implies broad use, but it does not state exclusions or clearly delineate text vs document translation.

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