ncloud_livestation_update_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 profile is covered. The description adds which fields are mutable but omits partial-update semantics (are unspecified fields left unchanged?) and the fact that channelName must be resupplied even when unchanged — a behavior that matters for a live channel update. Modest value 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?

One front-loaded sentence with no filler; the mutable-field list is compact. The trailing '(vodchannelupdate)' is low-value to an agent 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 mutation on a live streaming channel, the definition covers what changes but not the operational consequences, required permissions, or what happens to the running stream. Annotations and the complete schema carry part of the load, leaving this adequate but with clear gaps.

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 schema documents each parameter, including the required-by-API note for channelName and enums for envType/outputProtocol. The description merely restates the field list, adding no format or constraint detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb (Update) and resource (Live Station VOD-to-Live channel), and enumerates the mutable fields (name, environment type, output protocol). It is distinguishable from the sibling ncloud_livestation_update_channel only by the 'VOD-to-Live' qualifier, which is present but not explicitly contrasted.

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 guidance, no prerequisites, and no mention of the related siblings (update_channel, create_vod_channel, start/stop_vod_channel) that an agent would need to choose between. The description only says what can be changed, not when this tool is the right call.

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