update_app_info_localization

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It states the tool 'Update's, implying mutation, but does not describe the update semantics (e.g., partial vs full replacement), side effects, required permissions, or success/error responses. This is insufficient for an operation likely requiring authorization.

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 consists of two short, focused sentences. The first sentence conveys the core purpose and key fields, the second provides a workflow step. No redundant or extraneous text.

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?

Without an output schema, the description does not explain what the tool returns on success or failure. While it covers the input and prerequisite, it lacks information on the output format, which is necessary for an agent to use the response. With 6 parameters and a required ID, more detail on update behavior would be helpful.

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 schema already documents all 6 parameters. The description adds context by grouping parameters (name, subtitle, privacy policy) but does not provide new semantic value beyond what the schema descriptions offer. 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 clearly states the verb 'Update' and the resource 'app info localization', listing specific fields (name, subtitle, privacy policy) which helps distinguish from sibling tools like create or list localizations. However, it could be more explicit in differentiating from other update tools like update_version_localization.

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 includes a critical prerequisite hint: 'Use list_app_info_localizations first to get the localization ID.' This provides clear context for when to use this tool. It does not explicitly exclude alternative tools, but the hint is valuable and guides proper sequence.

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