beta_app_localizations_app_get_to_one_related

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

No annotations are provided, so the description carries the full burden of behavioral disclosure, yet it adds nothing beyond the raw endpoint path. It does not state that the operation is read-only, what the response contains, whether the relationship is guaranteed, or any auth requirements.

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 technically short, but it wastes its only content by duplicating the same endpoint path in parentheses. This redundancy does not earn its place and leaves the tool under-specified.

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 explain the relationship being fetched and the expected return. Instead it provides only an endpoint path, leaving an agent without enough context to confidently select or invoke the tool.

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 schema already documents both parameters, including the id and fields_app enum list. The description adds no further meaning about parameter semantics, so the baseline score of 3 applies.

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 is only the HTTP path "GET /v1/betaAppLocalizations/{id}/app" repeated twice, with no natural-language statement of what the tool does. It implies fetching the app related to a beta app localization, but an agent must infer that from the URL rather than from an explicit verb and resource description.

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 instead of alternatives such as beta_app_localizations_app_get_to_one_relationship, beta_app_localizations_get_instance, or the sibling apps endpoints. The description provides no context, exclusions, or prerequisites.

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