ncloud_livestation_get_service_url

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

Annotations already declare readOnlyHint=true, so the description adds context about the specific URLs returned (publish/play), but does not disclose other behavioral traits like error handling, rate limits, or authentication requirements. The description adds some value but not substantially beyond 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?

The description is a single sentence of 12 words with no unnecessary information. It is front-loaded with the action and clearly states the output. Every word earns its place.

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 operation with one parameter and good annotations, the description provides sufficient context about what is returned (publish/play URLs). However, the lack of an output schema means the exact structure is not documented, and the description could hint at the response format.

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?

With 100% schema description coverage, the schema already describes the channelId parameter. The description does not add new meaning beyond what the schema provides. Baseline score of 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 uses a specific verb ('Get') and resource ('streaming service URLs'), clearly stating it retrieves both publish and play URLs for a Live Station channel. It distinguishes from siblings like 'ncloud_livestation_list_channels' (which lists channels) and 'ncloud_livestation_get_channel' (which gets channel details).

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 does not provide explicit guidance on when to use this tool versus alternatives. It lacks when-not-to-use instructions and does not reference sibling tools. The usage context is implied but not stated.

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