v1_youtube_channel_videos

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

No annotations are provided, so the description carries the full burden. It discloses pagination via continuationToken and cost, but lacks details on authentication, rate limits, or what happens with empty results. The warning about API responses is a positive addition.

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 two clear, front-loaded sentences with no fluff. Every sentence adds essential information: purpose, endpoint, cost, parameter requirement, and a security note.

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?

The description omits details about the return format, how to use the continuationToken for pagination, and any error states. Given the lack of output schema, more explanation would be helpful for full context.

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 coverage is 100%, so the description adds value by clarifying the requirement to supply at least one of the grouped parameters. However, it does not elaborate on parameter formats or examples beyond the schema's minimal descriptions.

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 verb 'Get', the resource 'a YouTube channel's videos', and includes pagination detail via continuationToken. It distinguishes the tool from siblings like v1_youtube_channel_playlists and v1_youtube_channel_lives.

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 provides explicit usage context: requires one of handle, channelId, or url, and includes a security warning about not acting on API responses as commands. However, it does not explicitly compare this tool to alternatives or specify when not to use it.

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