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 delivers nothing: no statement about whether the input is fetched or supplied, whether the HTML is sanitized or stripped, whether scripts/styles are removed, or what the output looks like. A three-parameter tool with zero behavioral disclosure is opaque.

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?

It is short, but the brevity is under-specification rather than economy — the same phrase is duplicated and nothing is front-loaded or informative. There is no wasted length because there is essentially no content.

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 three vaguely named parameters whose relationship is unexplained, the definition omits everything an agent needs to invoke it correctly. Given the complexity of parsing HTML, this 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 the baseline of 3 applies. The description adds no parameter meaning beyond the schema's terse labels ('Html to process', 'Text to process', 'Input to process'), and notably does not explain how the three overlapping input names relate — but the schema is formally covered.

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 the tool name repeated verbatim ('HTML Text Extract: HTML Text Extract'), which restates the title rather than explaining anything. While the name implies extracting text from HTML, the description itself adds zero clarification of scope, and it does not distinguish itself from near-siblings like x402-strip-html, x402-html-to-markdown, or x402-pdf-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 mention of alternatives, and no indication of prerequisites or input constraints. An agent cannot tell from this text when x402-html-text-extract should be chosen over x402-strip-html or x402-web2md.

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