Get channel recent videos

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It does disclose useful behavior: 'Newest first' and the raw YouTube fields returned. However, it does not mention failure behavior, authentication needs, rate limits, or what happens for invalid or missing channels.

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 a single, information-dense sentence. It front-loads the action, then adds output fields and ordering without filler or redundancy.

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 two-parameter list operation, the schema covers inputs and the description partially compensates for the missing output schema by naming the fields and ordering. It still lacks explicit guidance on errors, the meaning of 'recent' beyond sorting, and sibling routing, but the core is complete enough for correct invocation.

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 already documents both `channel` and `limit` with descriptions and defaults. The tool description adds value by framing the result as 'most recent videos', but it does not provide parameter-level meaning beyond the schema.

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 states a specific action and resource: 'List a channel's most recent videos', and adds the output fields ('views, likes, comments, duration, publishedAt') and ordering ('Newest first'). This clearly distinguishes it from siblings like resolve_channel or get_trending, which serve different purposes.

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 intended use is implied by the channel-specific framing, but the description does not explicitly say when to use this tool versus alternatives such as get_trending or find_outlier_videos. It provides no exclusions or routing hints, so an agent must infer the appropriate context.

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