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

Annotations indicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description correctly describes a read operation, so no contradiction. It adds the bulk execution capability, but does not disclose what happens if both single and bulk parameters are provided, or if the PLS file format has any caveats. The burden is partially on annotations, which are already good.

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 short and front-loaded with the purpose, but it repeats the same sentence twice ('Get A Pls File With A Pronunciation Dictionary Version Rules. Get a PLS file with a pronunciation dictionary version rules'). This redundancy wastes space and reduces efficiency.

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 tool with 5 parameters and no output schema, the description is under-specified. It explains the bulk support but lacks details on parameter usage, return format, or behavior. The annotations cover basic safety, but the description should provide more context about the PLS file, dictionary/version relationships, and possible errors.

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 0%. The description only mentions bulk support with dictionary_ids and version_ids, but fails to explain the purpose of the other parameters: account, dictionary_id, version_id. It doesn't clarify which parameters are required or how they interact, leaving most parameters undocumented semantically.

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 tool retrieves a PLS file with pronunciation dictionary version rules, using the verb 'Get'. It distinguishes from siblings like metadata retrieval tools, but could be more explicit about the specific resource (version rules). The name itself is redundant, but the description adds clarity.

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 mentions bulk support, indicating when to use batched parameters (dictionary_ids, version_ids), but doesn't explicitly state when to use this tool versus alternatives like getting metadata or updating dictionaries. It implies usage but lacks exclusions or alternative recommendations.

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