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

The description adds substantial behavior beyond the annotations: it says scripts, navigation, and ads are removed; title, meta description, and token estimate are included; truncation is marked; and pricing is $0.002 with empty results free. These details are highly useful for an agent deciding whether and how to call the 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 description is a single dense sentence that front-loads the core operation and then adds the most decision-relevant constraints: output cleanliness, max_chars range, and cost. Every clause carries useful information.

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?

Given 100% schema coverage, an output schema, and annotations covering read-only/open-world behavior, the description supplies the remaining decision-critical context: public-page scope, cleaning behavior, truncation, token estimate, and pricing. An agent has enough information to call it correctly.

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 schema already documents url, context, and max_chars thoroughly. The description restates max_chars bounds and default and adds the pricing note, but it does not add parameter meaning beyond what the schema provides; baseline 3 is appropriate.

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 clearly states that it converts a public web page into clean Markdown, including title, meta description, and token estimate, while removing scripts, navigation, and ads. It is specific about the operation and output traits, but it does not distinguish itself from possible sibling URL-conversion tools such as universal_product_url_to_json.

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?

The word 'Public' implies that private pages are out of scope, and the pricing note helps frame usage economics. However, there is no explicit when-to-use guidance, no stated alternatives, and no when-not-to-use conditions beyond the public-page constraint.

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