get_channel_videos

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

With no annotations provided, the description carries the behavioral disclosure burden. It conveys a read-style retrieval operation and mentions sorting by date or view count, but it does not explain return format, whether 'recent' maps to upload date, or how viewCount ordering behaves. Some behavioral context is present, but important gaps remain.

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 short sentences with no filler, and the primary action is front-loaded. The sorting behavior is stated secondarily and the text is easy to scan.

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 and schema are adequate for basic invocation, but the absence of an output schema and the lack of explicit differentiation from similar video-listing tools leave gaps. An agent selecting among many channel- and video-related siblings would benefit from a note about what is returned or when to use this tool instead of others.

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?

The input schema already provides full descriptions for all three parameters, including the url format, enum values, defaults, and bounds. The description adds no additional parameter-level meaning, so the baseline of 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?

The description clearly names the operation ('Get recent videos') and the resource ('YouTube channel'), and mentions the sorting capabilities. This makes it easy to distinguish from get_trending_videos, which is not channel-scoped, and from search_within_channel, which is search-oriented rather than a recent-videos listing.

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 channel-scoped phrasing implies when this tool is appropriate, but there is no explicit guidance about when to prefer it over siblings like get_trending_videos or search_within_channel. No exclusions, alternatives, or use-case conditions are stated.

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