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

No annotations are provided, so the description carries the full burden. It does not disclose what the tool returns, whether it is a read operation, how pagination works, or any other behavioral details. The description is completely opaque.

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?

At one word, it is extremely brief, but this is under-specification rather than effective conciseness. The description does not earn its place for a tool with two parameters and significant sibling overlap.

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 annotations, no output schema, and a one-word description, the tool is contextually empty. It provides no explanation of expected output, error conditions, or how it relates to similar tools, leaving the agent unable to use it effectively.

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 both url and cursor well documented in the input schema. The description adds no additional parameter context, but the schema alone provides enough meaning, so the baseline 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?

The description is simply the word 'Comments,' which merely restates the tool name. It lacks a verb or specific resource description and fails to distinguish this from sibling tools like scrapecreators_comments_get or scrapecreators_post_comments.

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 guidance is given on when to use this tool versus alternatives. With a large sibling list and no context, an agent has no way to decide if this is the right tool for obtaining comments.

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