ncloud_advisor_download_category_results

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

Annotations already indicate readOnlyHint=true, so the agent knows this is a safe read operation. The description adds that the tool returns a download URL or binary data for an Excel report, providing some output behavior. However, it does not disclose potential rate limits, size constraints, or authorization requirements beyond what annotations and schema imply.

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 that efficiently conveys the tool's purpose and output. Every word adds value, with no redundancy or unnecessary 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 tool with one parameter, the description is adequately complete, covering the action and the return format. It could optionally mention whether the download is synchronous or asynchronous, but the description gives sufficient context for an agent to invoke it correctly.

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%, with the parameter categoryCode having an enum description. The description does not add additional meaning beyond the schema, so it meets the baseline of 3.

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 downloads check results for all items in a category, using the verb 'Download' and specifying the resource as 'check results for all items in a category.' This distinguishes it from sibling tools like ncloud_advisor_download_item_results and ncloud_advisor_download_all_results.

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 is clear about the tool's purpose (category-level download) but does not explicitly mention when not to use it or suggest alternatives. However, the context from sibling tool names provides implicit guidance, and the description is sufficiently unambiguous for an agent to select this tool for category downloads.

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