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

The readOnlyHint annotation already declares this as a safe read operation, and the description's 'List' is consistent with that. However, the description adds no behavioral context beyond the annotation, such as region-specific availability, pagination, or output structure. With annotations present, this is adequate but not enhanced.

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 sentence, front-loaded with the verb 'List', and ends with a useful parenthetical clarifying 'engine versions'. There is no filler or redundant information.

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 simple read-only listing tool with one optional parameter, the description and schema together provide enough context to select and invoke the tool correctly. It does not explain what the product codes are used for or whether results are region-filtered, but these are not essential gaps given the tool's simplicity.

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 schema fully documents the only parameter, regionCode, including allowed values and default behavior, so schema coverage is 100%. The description itself adds no parameter-level meaning, but the baseline of 3 is appropriate since the schema carries the semantic weight.

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 uses the specific verb 'List' and identifies a clear resource: 'available Cloud DB for MySQL image product codes (engine versions)'. The parenthetical clarifies that this is about engine versions, distinguishing it from sibling compute-product tools like ncloud_get_mysql_products.

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 explicit when-to-use guidance or mention of alternatives. The description does not say that this should be used before creating an instance or that ncloud_get_mysql_products is for compute specs. Usage is only implied by the list action itself.

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