apps__beta_app_localizations__list

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the description needs only to add context. It adds the scoping and endpoint, but doesn't describe pagination behavior or response structure beyond the schema. That is acceptable given the annotations.

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?

One sentence plus endpoint, zero waste. The description is front-loaded and immediately clarifies the tool's purpose.

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 simple list operation with comprehensive schema and annotations, the description provides the essential purpose and scope. It doesn't detail response format, but that is partially implied by 'list the ... localizations'. Could be more thorough, but this is adequate for the tool's simplicity.

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 all parameters. The description's reference to 'an app' clarifies the id parameter's role, but it doesn't add syntax or format details 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 uses a specific verb ('List') with a clear resource ('beta app localizations') and scope ('belonging to an app'), and includes the REST endpoint. This distinguishes it from the sibling beta_app_localizations__list, which likely lists all localizations.

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 phrase 'belonging to an app' clearly indicates this is for retrieving localizations of a specific app, giving context for when to use this tool. However, it does not explicitly name alternatives or state when not to use it, but the scope is clear enough.

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