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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states nothing about wrapping rules (hard vs soft wrap), whitespace handling, newline behavior, or output structure, leaving the agent with zero behavioral context for a text-mutation tool.

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 sentence is short but degenerate rather than economical; it conveys no information. This is under-specification, not conciseness, and there is no front-loaded substance to reward.

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, no output schema, and ambiguous duplicate parameters (text vs input), the description should explain wrapping behavior and clarify parameter roles. It does none of this and 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 description coverage is 100%, so per the rubric the baseline is 3. However, the schema's own descriptions ('Text to process', 'Input to process', 'Width to process') are generic placeholders, and the description adds nothing to clarify what distinguishes 'text' from 'input' or that width should be numeric despite being typed as a string.

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 'Word Wrap: Word Wrap', a pure tautology that restates the tool name twice without adding a verb-object statement of what it does. An agent learns only that it wraps words, with no distinction from siblings like x402-wrap-text or x402-truncate-words.

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 whatsoever on when to use this tool, when not to, or which sibling (e.g., x402-wrap-text) to prefer. The description supplies nothing beyond the name.

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