ncloud_vodstation_stop_channel

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

Annotations already indicate idempotent and non-destructive behavior. The description adds value by specifying the READY status precondition, which is a behavioral constraint not visible in annotations. It does not describe error handling for non-READY channels, but the key state requirement is disclosed.

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, concise sentence that front-loads the action and resource. It contains no unnecessary words or repetition.

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 simplicity of a one-parameter state-change tool with good annotations and schema coverage, the description is nearly complete. It omits what happens if the channel is not in READY status, but this is a minor gap for such a straightforward operation.

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?

The input schema already fully describes the single parameter (channelId) with 100% coverage. The description adds no additional parameter context, but the schema's description is sufficient, so the baseline 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 clearly states the action (stop), the resource (VOD Station channel), and a condition (in READY status). It distinguishes from sibling tools like ncloud_vodstation_start_channel and ncloud_vodstation_delete_channel by specifying the state transition.

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 phrase 'that is in READY status' provides a clear prerequisite for usage, implying it should only be called on channels in that state. However, it does not explicitly mention alternatives like starting or deleting a channel, though sibling names make that context available.

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