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: not whether text is truncated, whether line breaks are inserted or returned as a list, whether whitespace is collapsed, or what the output looks like. For a 4-parameter tool with zero annotation coverage this is a complete gap.

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 wasted entirely — it repeats the tool name verbatim rather than front-loading any actionable information. Brevity here reflects under-specification, not conciseness.

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, four undocumented parameters (only non-required), and a redundant parameter pair (w/width), the definition is far too thin for an agent to invoke it correctly. Every element an agent needs is absent.

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 nominally 100%, but every parameter description is filler ('W to process', 'Text to process', 'Width to process'), so the schema documents nothing semantically. Two parameters (w and width) plainly denote the same concept and 'width' is typed as a string, yet the description offers no clarification of which to use or their expected format.

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 'Text Wrap: Text Wrap', a pure tautology that merely restates the name and title. It names no verb, no resource semantics, and gives no basis for distinguishing it from the many sibling wrapping/formatting tools such as x402-word-wrap or x402-wrap-text.

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 mention of alternatives. An agent has no way to know whether this tool differs from the near-identical siblings x402-word-wrap and x402-wrap-text.

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