app_store_version_experiment_treatment_localizations__create

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

Annotations already indicate readOnlyHint=false, idempotentHint=false, destructiveHint=false. The description only says 'Create', adding no additional behavioral traits like required permissions, idempotency guarantees, or side effects. It fails to disclose any important constraints beyond what is already known.

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 one sentence plus a URL, extremely concise and front-loaded. No unnecessary words.

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?

The tool has a complex nested input schema and no output schema. The description does not explain what a treatment localization is, what happens upon creation, or what the response contains. It is insufficient for an agent to fully understand the tool's role in the broader workflow.

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 coverage is 100%, so the input schema already documents the required nested structure with attributes (locale) and relationships. The description adds no extra meaning beyond labeling the body as 'JSON:API request body'. It does not explain the purpose of locale or the relationship.

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 'Create an App Store version experiment treatment localization' with a specific verb and resource. It distinguishes from siblings like app_store_version_experiment_treatments__create and app_store_version_experiment_treatment_localizations__delete.

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 no guidance on when to use this tool versus alternatives. For instance, it doesn't explain when to create a localization vs. creating a treatment, or vs. getting/deleting a localization. Agents need explicit context to choose correctly.

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