get_fetched_url_details

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

The description states what the tool returns (FetchedUrlDetails) and that it raises BingWebmasterError, adding some behavioral transparency. However, with no annotations, it does not disclose side effects, permission requirements, rate limits, or what 'fetched' status implies. It is a read operation by name but this is not explicitly stated.

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: one summary sentence, then Args, Returns, and Raises sections, each with a single line. No filler or repetition beyond the weak site_url text.

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 an output schema absent and many sibling tools present, the description does not explain how this relates to fetch_url or get_fetched_urls, nor what conditions must hold (e.g., URL must have been fetched). It gives the essentials but leaves relationship and return-structure details unsaid.

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 coverage is 0%, so the description must compensate. It lists both args but site_url's description ('The URL of the site') is nearly tautological jew and url's ('The specific URL to get details for') merely restates the tool's purpose. Basic placeholder semantics, not enough to resolve ambiguity.

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 'Get detailed information about a specific fetched URL' gives a clear verb and resource. It is distinct from siblings like fetch_url and get_fetched_urls, though it does not explicitly call out that distinction. Overall purpose is unambiguous.

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?

No guidance is provided about when to use this tool versus related siblings (fetch_url, get_fetched_urls). There is no mention of prerequisites, such as the URL needing to have been previously fetched or being associated with the given site_url.

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