ncloud_livestation_list_channels

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

Annotations show readOnlyHint: true, which the description supports. The description adds pagination context but does not disclose other behavioral traits (e.g., rate limits, default order, result format). Given the annotation covers safety, the description adds minimal extra transparency.

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 directly conveys the core action and pagination feature. No redundant or extraneous information. It is appropriately front-loaded.

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?

Given the tool has 2 optional parameters and no output schema, the description is minimally adequate. It covers the basic functionality but lacks details about the response structure or any limitations (e.g., maximum page size). For a simple list operation, it is sufficient but not comprehensive.

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% with each parameter described (pageNo and pageSizeNo with defaults). The description's mention of 'pagination' aligns with these parameters but adds no new semantic information beyond the schema. Baseline 3 is appropriate.

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 'List all Live Station streaming channels with pagination' clearly states the verb, resource, and scope. It distinguishes this tool from siblings like 'ncloud_livestation_get_channel' (single channel retrieval) and 'ncloud_vodstation_list_channels' (different service).

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 pagination but does not explicitly state when to use this tool versus alternatives (e.g., get_channel for a specific channel). Usage context is implied but not clearly guided.

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