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

No annotations exist, so the description carries the full disclosure burden. It provides zero behavioral context—nothing about what the tool computes, what units are involved, whether it requires prerequisites, or what the response looks like. The description is entirely uninformative.

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, but this is under-specification rather than conciseness. Its only content is a verbatim repetition of the name, so no sentence earns its place; there is no informative material to be concise about.

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 a vague name, the description needed to explain the tool's purpose, inputs, and outputs. It provides none of this, making the tool essentially indistinguishable and uncallable with any confidence.

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 has zero parameters, so the 0-param baseline of 4 applies and schema coverage is trivially 100%. There are no parameter descriptions needed, though the description misses the chance to mention conceptual inputs like voltage and resistance.

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 'Ohms Law I: Ohms Law I' is a pure tautology, restating the tool name without adding a verb, resource, or any functional meaning. It does not distinguish this tool from sibling tools like x402-ohms-law-r or x402-ohms-law-v.

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?

There is no guidance on when to use this tool versus alternatives. Given that sibling tools x402-ohms-law-r and x402-ohms-law-v exist, the absence of any mention of them or a selection condition leaves the agent completely without routing information.

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