ncloud_livestation_start_vod_channel

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

Annotations already declare idempotentHint=true and destructiveHint=false, so safety is covered by structured data. The description adds nothing beyond a restatement of the operation—no auth requirements, no effect on the channel's current state, no note on what happens if already on (even though idempotency implies it).

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 with no filler. The parenthetical codename is slightly redundant but harmless.

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 one-parameter tool with annotations and no output schema, the definition is minimally viable. The main gap is lack of routing against the closely related stop/delete VOD channel siblings.

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% and the single channelId parameter is documented in the schema. The description adds no syntax, format, or sourcing detail for channelId, so 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 states a specific verb ('Turn ... on') and resource ('Live Station VOD-to-Live channel'), so the agent can distinguish it from siblings like stop_vod_channel and delete_vod_channel. However it does not explicitly name those siblings, and the trailing codename '(vodchannelon)' is redundant with the name rather than clarifying.

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?

No when-to-use or when-not-to-use guidance. Given the presence of ncloud_livestation_stop_vod_channel and ncloud_livestation_delete_vod_channel, the description could have specified preconditions (e.g., channel must be off) but offers nothing.

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