ncloud_drm_list_sites

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

The annotation readOnlyHint=true already indicates a safe read operation. The description adds 'with pagination,' which is useful context but largely duplicates what the schema parameters express. It does not disclose other behavioral traits like response ordering, rate limits, or whether all sites are returned regardless of tenant scope. No contradiction with annotations.

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, front-loaded sentence that directly conveys the purpose and key feature (pagination). No wasted words, and the structure is optimal for a simple list tool.

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 list tool with two well-documented parameters and no output schema, the description is mostly sufficient. It covers the core purpose and pagination capability. However, it lacks any detail about the response format or what fields are returned for each site, which would help an agent anticipate output. Given the tool's simplicity, this is a minor gap.

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 coverage is 100%; both pageNo and pageSize have descriptions in the schema. The description's mention of 'pagination' adds minimal meaning beyond the schema. It doesn't clarify e.g. whether pageNo starts at 0 or 1, but the schema says 'default 1', so the description does not significantly compensate for any ambiguity.

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 a specific verb ('List') and a specific resource ('One-Click Multi DRM sites'), with the added detail of pagination. This distinguishes it from sibling tools like ncloud_drm_get_site (get a single site), ncloud_drm_create_site (create), and ncloud_drm_update_site (update).

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 implies when to use the tool: when you need to list DRM sites, especially with pagination. However, it does not explicitly state alternatives or exclusions (e.g., 'use get_site for a single site' or 'use list_policies for policies'). The name itself signals list vs. get, but explicit guidance is absent.

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