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

With no annotations and a one-word description, the tool's behavior is completely opaque. The agent learns nothing about pagination, return format, rate limits, or side effects.

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 under-specified to the point of being a tautology. It is not concise but rather an empty placeholder that fails to communicate any meaningful structure or content.

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 tool has no annotations, no output schema, and only a one-word description. Given the presence of a continuation token parameter, the description should explain how pagination works and what the response contains, but it explains nothing.

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%, with each parameter having a description. The baseline for high coverage is 3, and the tool description adds no additional parameter semantics 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 is a single noun 'Comments', which merely restates the tool name and provides no verb or resource context. It does nothing to distinguish this tool from siblings like 'scrapecreators_comments' or other comment-related tools.

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?

There is no guidance on when to use this tool versus alternatives. The description does not mention scenarios, prerequisites, or relationships to sibling tools such as 'scrapecreators_comments'.

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