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 whether this is a read or compute operation, what the inputs represent, whether the strings are numeric, or what the result is. A single tautological line for an unannotated tool is a total transparency failure.

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 extremely short, but the brevity reflects under-specification rather than efficient communication — every token is redundant with the name. There is no front-loaded statement of purpose.

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 no usable description, an agent has nothing to determine what the tool returns or how to interpret the EV/EBITDA computation. Everything an agent needs is missing.

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%, so both parameters (ebitda, enterpriseValue) are already named and minimally described as "to process" in the schema; baseline 3 applies. The description adds no meaning beyond the schema, merely echoing the parameter names in its title-like text.

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 the literal string "Ev Ebitda: Ev Ebitda", a pure tautology that restates the tool name and adds no verb or resource specification. An agent cannot tell from this text whether the tool computes a ratio, fetches data, or validates inputs.

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 when-to-use guidance, no prerequisites, and no reference to any of the hundreds of sibling finance tools (e.g. x402-enterprise-value, x402-ebitda-style tools). Nothing indicates the intended context.

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