update_keywords

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

With no annotations available, the description carries full responsibility for behavioral disclosure. It only says 'Update the keywords,' but does not mention whether existing keywords are replaced, whether any validation is performed, or what side effects occur. It also fails to state any authentication or permission requirements.

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 short sentence with no unnecessary words, which earns it a middle score. However, it is under-specified: it does not explain the parameter relationships or the behavior beyond the bare action. It is concise but lacks the detail needed for full clarity.

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 is relatively simple with two required parameters and no output schema, but the description still feels incomplete. It does not address the need to have an existing localization, the replace-vs-merge semantics, or how this relates to the broader app store localization workflow. Given the absence of annotations, this is a notable gap.

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 input schema already provides descriptions for both parameters (localizationId and keywords), achieving 100% schema coverage. The description adds no extra meaning beyond what the schema offers, so the baseline score of 3 applies.

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 identifies the action ('Update') and the target ('keywords') along with a scope ('for a specific locale'). It distinguishes from siblings like update_app_description and update_whats_new by naming the specific resource. However, it does not explicitly state that it operates on an app store version localization, leaving some ambiguity.

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?

No guidance is provided on when to use this tool versus alternatives. Siblings such as update_app_description and update_whats_new exist for other fields, but the description does not indicate the appropriate context for choosing this one. The intended use is only implied by the name and brief description.

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