age_rating_declarations_update_instance

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

No annotations are provided, so the description carries the full behavioral burden. It discloses only that this is a PATCH (implying a partial mutation) and points at an external schema; it says nothing about required permissions, whether the change is reversible, what happens to unspecified fields, or any side effects of mutating an age rating declaration.

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 single sentence duplicates the exact same endpoint string 'PATCH /v1/ageRatingDeclarations/{id}' in parentheses, which is pure waste. It is short but structurally flawed because roughly half its content is redundant rather than additive.

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 mutation tool with no annotations and no output schema, the description is inadequate: it never explains what the update accomplishes, which fields are modifiable, or what the caller should expect. It offloads everything to an external OpenAPI document an agent may not have access to, leaving the tool underspecified.

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% and both parameters (id, body) are documented in the schema. The description only repeats the schema's body reference to components.schemas.AgeRatingDeclarationUpdateRequest, adding no new meaning; per the high-coverage baseline, 3 is appropriate.

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 conveys a verb/action (PATCH) and the target resource (ageRatingDeclarations/{id}), so an agent can infer this updates one age rating declaration. However, it is phrased as a bare HTTP endpoint rather than a purpose statement, and it does nothing to distinguish itself from the many sibling update_instance tools or the age-rating relationship tools (e.g. app_infos_age_rating_declaration_get_to_one_relationship).

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 when-to-use guidance, no prerequisites, and no mention of alternatives. The agent is not told when this update should be preferred over sibling tools that also touch age rating declarations or app info. Only the mechanical HTTP method is provided.

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