ncloud_drm_list_sites

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

The readOnlyHint=true annotation already tells the agent this is a safe, non-mutating read. The description adds only that results are paginated, which is useful but thin; it says nothing about default page behavior, ordering, or result shape.

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?

A single compact sentence with the resource named first and the pagination qualifier second; nothing is wasted. It is under-elaborated rather than over-long.

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 two-param read tool with annotations covering safety and no output schema, the minimum is nearly met. However, the agent gets no indication of what a 'site' record contains or whether pagination defaults matter, so it is adequate but not complete.

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 pageNo and pageSize are already fully documented in the schema with ranges and defaults. The description's 'with pagination' adds no syntax or constraint detail beyond that, so the baseline 3 applies.

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?

States a specific verb ('List') and resource ('One Click Multi DRM sites') plus the pagination scope. It is clearly distinguishable from ncloud_drm_get_site (singular fetch) by the plural 'sites' + list verb, though it never explicitly names or contrasts with that sibling.

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 when-to-use guidance and no mention of alternatives such as ncloud_drm_get_site for a single site. The only implied usage is the 'list' verb itself, leaving the agent to infer when this beats the getter.

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