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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses nothing: not whether this reads or writes, not the expected input domain, not the return shape. The agent cannot predict any behavior from this text.

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 text is short, but its brevity comes from omission rather than efficiency: the same word is repeated with no added information. There is nothing front-loaded because there is nothing to front-load.

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 3-parameter tool with no annotations and no output schema, the description leaves every relevant question unanswered: what it operates on, required inputs, units, and result format. It is completely inadequate.

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 schema nominally documents all three parameters, but the 'descriptions' are placeholder noise ('To to process', 'From to process', 'Value to process') that conveys no meaning about what to/from/value represent for a temperature operation. The description adds nothing beyond this, so the mechanical high-coverage baseline of 3 is not earned.

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 'Temperature: Temperature', a pure restatement of the tool name with no verb, resource, scope, or differentiator. It gives an agent no way to tell it apart from siblings such as x402-temperature-convert, x402-temp, or x402-color-temperature.

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 when-to-use, when-not-to-use, or alternative-tool guidance of any kind. With dozens of temperature/unit-conversion siblings present, the absence of routing information is actively harmful.

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