semrush_backlinks_domains

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

No annotations are provided, and the description lacks details about behavioral traits such as authentication requirements, rate limits, or whether the operation is read-only (implied but not stated). The description does not disclose any side effects or constraints.

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 that is concise and to the point. Every word contributes to the purpose, with no extraneous 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 the lack of an output schema, the description should provide more context about what referring domains are, how the limit affects results, and what the response looks like. The minimal description leaves an AI agent guessing about the tool's output and behavior.

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 input schema already covers both parameters (target, limit) with descriptions, achieving 100% coverage. The description adds minimal extra meaning beyond 'for a specific domain or URL', which mirrors the schema's description. Thus, baseline score of 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 the verb 'Get' and the resource 'referring domains' with a specific scope 'for a specific domain or URL'. This effectively distinguishes it from sibling tools like semrush_backlinks which likely return backlinks, not just domains.

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 no guidance on when to use this tool versus its siblings. For instance, it does not differentiate between semrush_backlinks_domains and semrush_backlinks, nor does it suggest prerequisites or context for invocation.

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