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

No annotations are provided, so the description carries the full burden of behavioral disclosure. However, it offers no information about what the tool does operationally—whether it fetches data, analyzes websites, requires authentication, has rate limits, or returns structured data. The description is too minimal to convey any behavioral traits, making it inadequate for a tool with zero annotation coverage.

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?

While the description is brief, it's under-specified rather than appropriately concise. A single phrase ('Top Website Languages Report') fails to convey essential information, making it inefficient. It lacks front-loaded clarity and doesn't earn its place with meaningful content, resulting in poor structure despite its brevity.

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's complexity (implied by its name among analytics-focused siblings) and the lack of annotations and output schema, the description is insufficiently complete. It doesn't explain what the report contains, how it's generated, or what the output looks like, leaving critical gaps for an agent to understand and use the tool effectively in context with its siblings.

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 tool has 0 parameters with 100% schema description coverage, so there are no parameters to document. The description doesn't need to compensate for any gaps, and the baseline for such cases is 4. However, it doesn't add any parameter-related context beyond the schema, which is acceptable given the absence of parameters.

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 'Top Website Languages Report' is essentially a tautology that restates the tool name without adding meaningful context. It lacks a specific verb and doesn't clarify what the tool actually does (e.g., generates, retrieves, analyzes). While it mentions 'report,' the purpose remains vague compared to sibling tools like 'top_cms_report' or 'top_web_technologies_report' which have similar naming patterns but equally unclear descriptions.

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 description provides no guidance on when to use this tool versus alternatives. It doesn't mention any context, prerequisites, or exclusions, and fails to differentiate it from sibling tools like 'top_web_technologies_report' or 'top_cms_report' that might serve related purposes. This leaves the agent with no information to make an informed selection among similar-sounding tools.

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