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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention side effects, auth requirements, rate limits, or return shape, making it impossible for the agent to anticipate what invoking this tool will do.

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 extremely short, which might seem concise, but it is under-specification. It does not convey enough information to be useful and does not earn its place as a meaningful tool guide.

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?

Given the tool has 6 optional parameters, no output schema, no annotations, and a broad name, the description is completely inadequate. It lacks any explanation of return values, platform context, or how parameters interact, making it unusable for effective tool selection.

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 covers all 6 parameters with descriptions, so schema coverage is 100%. The tool description adds no additional meaning beyond the schema, meeting the baseline but not compensating for the vague parameter names like 'timePeriod' or 'commercialMusic'.

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 'Get popular songs' clearly states a verb and resource, but it is essentially a restatement of the tool name. It fails to define what 'popular' means, which platform or context it applies to, and does not distinguish it from sibling tools like scrapecreators_get_popular_videos or scrapecreators_get_song_details.

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 provided on when to use this tool versus the many sibling scraping tools. There is no mention of preferred use cases, required filters, or alternative tools, leaving the agent with no directional help.

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