update_version_localization

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

The description indicates a write operation ('updates') but lacks details on side effects, permissions required, or constraints beyond what the schema already provides. With no annotations, more behavioral context would be beneficial.

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?

Single-sentence description is concise and front-loaded with the verb and resource. However, it could be slightly more structured (e.g., listing fields explicitly) without losing conciseness.

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 description lacks important context such as the response format, error handling, or relationship to sibling tools (e.g., needing to get the localization ID first). For a tool with 7 parameters and no output schema, this is insufficient.

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 baseline is 3. The description adds 'etc.' hinting at other fields, but it mostly reiterates what the schema already conveys. No additional meaning beyond the parameter descriptions.

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 it updates version localization fields such as description, keywords, promotional text. However, it does not explicitly distinguish itself from sibling tools like 'update_app_store_version' or 'update_app_info', which could cause confusion.

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 on when to use this tool versus alternatives. It does not mention prerequisites (e.g., needing to get the localization ID via 'get_version_localizations' first) or when not to use it.

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