Get Video Ads channel

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered by structured data. The description's '[READ]' tag merely duplicates readOnlyHint and adds no information about error conditions, ID format expectations, or any limits — nothing beyond what annotations already say.

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 text is only one short line with no filler, so nothing is wasted, but it is under-specified rather than concise — brevity here reflects missing content, not efficient communication.

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 single-parameter read tool with no output schema, the description should at minimum explain what a channel object is and what identifier the agent must supply. None of that is present, and no return-value context exists to offset the omission.

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 0% and the single required parameter channel_id carries no description, minLength constraint documentation, or format hint. The path template {channel} only loosely implies the parameter is a channel identifier, leaving the description failing to compensate for the coverage gap.

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 reduces to "OpenAPI: GET /channels/{channel}", which restates the tool name as a raw HTTP endpoint rather than describing what a Video Ads channel is or what retrieval returns. It signals the operation is a read, but an agent cannot distinguish it from siblings like get_vod_channel, get_vads_domain, or get_vads_campaign based on this text.

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?

There is no when-to-use guidance, no stated prerequisites, and no mention of any alternative sibling tool. The only implicit signal is that it is a GET against a channels path.

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