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

No annotations are provided, so the description carries the full behavioral burden. The GET path implies a read-only retrieval, but there is no disclosure of permissions, error behavior, relationship inclusion effects, or what the response represents.

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?

It is short, but the endpoint is duplicated verbatim in parentheses, so part of the text does not earn its place. It is also a raw path rather than a structured, front-loaded explanation.

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 annotations and no output schema, the description should provide more context about the retrieved localization resource and its optional include/fields behavior. The schema covers parameters, but the description leaves the operation semantically underspecified.

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 100%, so the input schema already documents the id, include, and fields parameters thoroughly. The description adds no parameter meaning beyond echoing the path parameter, which meets the baseline for high schema coverage.

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 only repeats the raw endpoint path and duplicates it in parentheses, so it functions as a restatement of the tool name rather than a plain-language explanation of what is retrieved. It does show GET and an {id} placeholder, but does not clarify the resource's semantic purpose or distinguish it from sibling localization tools.

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 about when to use this single-resource GET versus sibling tools, nor any prerequisites or exclusions. The endpoint alone does not tell an agent when this tool is the right choice.

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