TDQS

C2.1/5.0
Behavior2/5

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

With no annotations, the description carries the full burden. It does disclose the x402 payment model (free trial per signed wallet), which is genuinely useful behavioral context, but it says nothing about units expected, precision of results, or what a call returns.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Very short and front-loaded, but the first clause is a redundant restatement of the name and the second is promotional pricing boilerplate; neither sentence explains how to compute or call the tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a formula tool with 0% parameter documentation, no annotations, and no output schema, the description should at minimum state the formula and units. As written, an agent must invent units and cannot predict the response shape.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and both parameters are typed as strings with no format hints. The description never mentions mass or velocity, so an agent gets no guidance on units (kg vs g, m/s vs km/h) or whether numeric strings or expressions are accepted.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

"Kinetic Energy: Energy of kinetic" essentially restates the tool name without naming a verb or resource action. An agent can guess this computes KE from mass and velocity, but only from domain knowledge, not from the text; nothing distinguishes it from siblings such as x402-potential-energy or x402-work.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, no alternatives named, no preconditions stated. The only contextual sentence concerns billing (5 free trial calls per signed wallet), which does not help select this tool over its many physics siblings.

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