Get YouTube Channel Videos

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

With no annotations, the description carries the full burden and does disclose that it returns a single explicit page and only public/recent uploads. However, it omits important behavioral details such as authentication requirements, ordering, rate limits, or potential error conditions, leaving significant gaps.

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 one concise sentence with no filler or redundancy. It is front-loaded with the core action and resource, and every word adds meaning.

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?

Despite having three parameters and no output schema, the description only provides a minimal overview. It does not explain how limit and pageToken affect results, what the response contains, or how to handle pagination—leaving the tool incomplete for an agent to invoke correctly.

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%, so the description must compensate for parameter meaning. It only clarifies that the 'url' parameter should be a YouTube channel URL, leaving 'limit' and 'pageToken' entirely unexplained. The phrase 'one explicit page' hints at pagination but does not map to the actual parameter usage.

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 uses a specific verb ('gets') and precisely identifies the resource ('one explicit page of recent public uploads from a YouTube channel URL'). It clearly distinguishes this from sibling tools like youtube_get_channel or youtube_search_videos by specifying it fetches uploads for a given channel.

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 no guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. It does not mention that youtube_get_channel_videos is the correct choice for paginated channel uploads as opposed to search_videos or playlist tools.

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