get_video_comments

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

No annotations provided, so description carries full burden. It only states 'retrieves comments' but fails to disclose pagination behavior (though pageToken parameter exists), sorting semantics beyond schema, or that it likely returns only top-level comments. Lacks disclosure of any side effects or auth requirements.

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?

Single sentence, front-loaded with the main action. Efficient, but could be slightly more informative without being verbose. No 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?

With no output schema and no annotations, the description should explain return values (e.g., comment fields, author, likes). It does not. Also lacks context on limitations like maximum results or that it retrieves only published comments. Incomplete for a read operation.

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 descriptions cover all 4 parameters (100% coverage), so description adds limited value. It does mention 'popular or latest' which aligns with the order parameter enum, but this is already in schema. Baseline score of 3 is appropriate.

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?

Description clearly states it retrieves popular or latest comments for a video, using specific verb 'retrieve' and resource 'video comments'. This distinguishes it from sibling tools like get_channel, get_video, search_videos, etc., which handle different entities.

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?

No explicit guidance on when to use this tool vs alternatives. The description does not mention when to prefer this over search or other retrieval tools, nor does it specify any prerequisites or use cases.

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