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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'follows a provided URL and extracts the main page content,' but lacks details on failure modes, handling of pagination/dynamic content, rate limits, or response structure. This is a significant gap for a read tool with no annotation coverage.

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 two sentences with no fluff. It front-loads the primary action and then immediately provides the use case. Every word earns its place, and it is highly scannable.

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 simple fetch tool, the description is adequate but not complete. It does not describe the return format, error handling, or edge cases (e.g., redirects, large pages). Without an output schema, this missing information is more noticeable, though the tool's simplicity mitigates the impact.

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 is 3. The description does not add extra clarification for 'maxContentLength' or 'url' beyond what the schema already provides, but this is acceptable given the schema's completeness.

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 the specific action ('Extract and return the full content from a single web page URL') and distinguishes itself from search tools by noting it is 'without performing a search.' This effectively differentiates it from sibling tools like full-web-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?

The description provides clear context on when to use the tool: when you have a specific URL and want detailed content, as opposed to searching. However, it does not explicitly name alternatives or state when NOT to use it, so it stops short of full guidance.

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