update_age_rating_declaration

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

No annotations are provided, so the description must fully disclose behavioral traits. It states 'update' implying mutation, but lacks details on permissions, rate limits, idempotency, or what happens to existing values. The description is insufficient for behavioral understanding.

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 sentence plus a value note, which is efficient. It is front-loaded with the main purpose. However, it could be slightly improved without adding excessive length. 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?

Given the tool has 19 parameters and no output schema, the description is too brief. It does not explain how the update works (e.g., partial vs full replacement), the significance of parameter groupings, or what the agent should expect as a response. More context is needed for effective use.

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 each parameter's meaning. The description's mention of enum values adds no extra semantics beyond what the schema provides. Baseline 3 is appropriate as description does not degrade or enhance schema info.

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 is to update the age rating declaration for an app, and specifies the valid enum values. It distinguishes from the sibling 'get_age_rating_declaration' which is a read tool, but does not explicitly differentiate among other update 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?

The description provides guidance on enum values ('NONE, INFREQUENT_OR_MILD, or FREQUENT_OR_INTENSE') but does not specify when to use this tool versus alternatives like 'get_age_rating_declaration' or other update tools. No explicit context on prerequisites or exclusions.

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