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

The description implies a read-only data retrieval operation ('provide you with a detailed overview'), while the annotations declare destructiveHint=true and readOnlyHint=false. This is a direct contradiction that would mislead an agent about the tool's safety profile, and the description adds no other behavioral context such as authentication or rate 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 a single front-loaded sentence with no wasted clauses. It could be slightly tighter, but it is appropriately sized for its 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?

Given the endpoint's rich parameter set and its placement among many similar siblings, the description is incomplete: it omits usage guidance, parameter details, and fails to reconcile the read-oriented wording with destructive annotations. Although an output schema exists, the description does not provide enough context to select or invoke the tool confidently.

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?

The context reports 0% schema description coverage for the top-level parameter, so the description is expected to compensate. It only vaguely refers to the 'specified website' and does not explain the required body structure, target format, or any of the nested filter/sort options.

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 states a specific verb (provide overview) and resource (anchors used when linking to the specified website with backlink data), making the tool's purpose clear. However, it does not distinguish this endpoint from the many sibling backlink endpoints, so it falls short of a 5.

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 guidance on when to use this tool versus alternatives, nor any prerequisites, exclusions, or context about selecting it among the numerous sibling backlinks endpoints. It merely states what the endpoint returns.

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