ncloud_vodstation_list_channels

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

The description is consistent with the readOnlyHint annotation (read operation) and adds the pagination context. However, it does not disclose additional behavioral details such as the response structure, ordering, or any rate limits. The annotation already covers the safety profile, so the description's contribution is limited.

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, front-loaded sentence with no wasted words. It efficiently conveys the core purpose and the pagination feature.

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?

The description covers the main purpose and hints at pagination, but is incomplete without an output schema to describe the return format (e.g., list of channel objects with fields). The tool is simple, so this is adequate but not fully informative for an agent.

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% – both parameters are documented in the schema with descriptions. The tool description only mentions 'with pagination', adding no new meaning beyond the schema. Baseline score of 3 is appropriate given the high schema coverage.

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 explicitly states 'List all VOD Station streaming channels with pagination', clearly identifying the verb ('list'), resource ('VOD Station streaming channels'), and scope ('all'). The inclusion of 'VOD Station' distinguishes it from the sibling tool 'ncloud_livestation_list_channels' which deals with Live Station.

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 usage for listing VOD channels but does not provide explicit guidance on when to use this tool versus alternatives like 'ncloud_vodstation_get_channel' for a single channel or 'ncloud_livestation_list_channels' for live channels. No exclusions or when-not-to-use information is given.

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