builds__beta_build_localizations__list

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the scoping constraint that results are limited to a single build, but does not disclose other behaviors like pagination details or error handling. With annotations present, this is adequate but not richly detailed.

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 a single concise sentence that front-loads the action and resource, followed by the endpoint reference. Every word serves a purpose with no redundancy or tangential information.

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 straightforward list operation with full schema coverage and clear annotations, the description is reasonably complete. It identifies the parent resource (build) and the exact endpoint. The lack of an output schema is mitigated by the simplicity of the tool, though explicit mention of pagination via limit/next_url is left to the schema.

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 provides descriptions for all four parameters, achieving 100% coverage. The description does not add additional meaning beyond the schema; the endpoint hints at the 'id' parameter but provides no extra detail. Baseline 3 is appropriate as the schema does the heavy lifting.

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 states the action 'List' and specifies the resource as 'beta build localizations belonging to a build.' The endpoint path [GET /v1/builds/{id}/betaBuildLocalizations] reinforces this scope, distinguishing it from the sibling beta_build_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 description provides clear context: use this tool when you need beta build localizations for a specific build, implied by the phrase 'belonging to a build.' However, it does not explicitly mention alternatives or when not to use it, such as using beta_build_localizations__list to fetch all localizations across builds.

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