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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not the input format, output shape, or any constraints. The description is a bare label.

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?

It is short, but the length reflects under-specification rather than conciseness — the same phrase is repeated (name then title), wasting the entire description.

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?

For a computational tool with no annotations, no output schema, and an undocumented parameter, the description is completely inadequate. An agent cannot know the expected input format or what the tool returns.

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 coverage is 100% for the single 'values' parameter, so baseline would be 3, but the description adds zero meaning beyond the schema — and the schema's own description ('Values to process') is itself uninformative for what should be a comma-separated numeric list.

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 essentially a tautology, restating the tool name 'Lorenz Curve' as both subject and object ('Lorenz Curve: Lorenz Curve'). While a knowledgeable agent might infer it computes a Lorenz curve, the description provides no verb or explanation of the operation, and among hundreds of siblings like x402-gini-coefficient it fails to distinguish itself.

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 usage guidance whatsoever — no when-to-use, no prerequisites, no alternatives mentioned. With no sibling differentiation, an agent has nothing to route on.

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