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

With no annotations, the description carries the behavioral burden. It usefully discloses the returned content structure (title, description, block text, Q&A), but does not explicitly state read-only behavior, error handling, URL/path handling, or any limits.

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 compact and front-loads the resource being returned, followed by content types and use cases. It is appropriately sized for a simple one-parameter retrieval tool, with only minor verbosity in the page-type list.

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 low-complexity retrieval tool with no output schema, the description gives a reasonable picture of returned content and intended use. However, it leaves the only parameter underspecified and does not clarify boundaries with sibling content tools, so it is adequate rather than complete.

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 0% for the single required path_or_url parameter. The description only incidentally includes an example path (“/repiteri/dlya-dachi/”) without explaining whether full URLs are accepted, expected path format, or required semantics.

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 returns website page text and enumerates page types (section, collection, brand, service, home) plus returned content elements (headline, description, block text, Q&A). It is specific about the resource, though it does not explicitly distinguish itself from sibling tools such as usilitel_article or usilitel_content_search.

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?

It gives a use case: explanations such as “how to choose” and service terms. However, it does not say when to use this tool versus alternatives or when not to use it, so the guidance remains implicit.

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