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: no output scale, no language assumptions, no determinism or rate-limit notes, no indication of whether the score is normalized. The tautological text adds no context beyond the name.

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 short but vacuous rather than concise; it duplicates the title and front-loads no useful information whatsoever.

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?

No output schema, no annotations, no meaningful parameter documentation, and no usage context. For a scored text-analysis tool sitting among hundreds of similar siblings, this definition 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?

Schema coverage is nominally 100%, but every one of the five parameters is documented with the same template phrase ('Text to process', 'Input to process', etc.), giving no semantic distinction between text, input, label, labels, and content. The description adds nothing, so an agent cannot tell which parameter to populate for a single-passage formality score.

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 'Formality Score: Formality Score', a pure restatement of the tool name with no verb, no resource, and no scope. An agent learns nothing about what the tool actually computes (e.g., a numeric formality rating for a passage) or how it differs from adjacent text-analysis siblings like x402-toxicity-score, x402-sentiment-score, or x402-readability-score.

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 guidance, no exclusions, and no named alternative. Within a sibling set containing dozens of text-scoring tools, the description provides zero routing signal for selecting this one.

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