semrush_domain_organic_unique

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

Annotations already declare readOnlyHint=true. The description adds the grouping behavior ('grouped by URL'), which is useful context beyond annotations, but does not disclose pagination, rate limits, or output format. With annotations covering safety, this is adequate but minimal.

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, clear sentence without fluff. However, it is extremely short and could be expanded to include parameter details without losing conciseness. It earns its place by stating the core purpose.

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?

The tool has 3 parameters, no output schema, and low schema coverage. The description fails to explain what 'grouped by URL' means in terms of output structure, returns format, or data limits. For a domain-level analytics tool, this is incomplete.

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%, and the description does not explain any parameters. It only implicitly references 'domain'. No meaning is added for 'database' or 'limit' beyond schema definitions.

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 unique organic keywords grouped by URL for a domain' uses a specific verb and resource, and explicitly mentions grouping by URL, which distinguishes it from sibling tools like semrush_domain_organic_keywords that likely return keywords without URL grouping.

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 alternatives, no prerequisites, and no exclusions. The user is left to infer from the tool name and sibling list.

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