get_domain_visits

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the agent knows this is a safe read operation. The description adds the domain-scoping behavior, which is useful, but beyond that it does not disclose other behavioral traits like pagination, date filtering, or response format.

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 conveys the core purpose without unnecessary words. It is concise and scannable, though it might be slightly too sparse for the number of parameters involved.

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 6 parameters, no output schema, and no parameter descriptions, the tool requires more context. The description does not explain pagination, date filtering, bot exclusion, or what the response contains, making it incomplete for an agent to invoke correctly without additional information.

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 compensate. It only indirectly clarifies the 'domain' parameter via 'under a specific domain', but gives no meaning for page, startDate, endDate, excludeBots, or itemsPerPage. The description adds minimal value beyond the parameter names.

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 action ('List') and the resource ('visits for short URLs under a specific domain'). It distinguishes itself from sibling tools like get_short_url_visits (per-URL visits) and get_tag_visits (per-tag visits) by specifying domain-level scope.

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 implies the use case (when you need visits filtered by domain) but does not explicitly state when to prefer this over alternatives or when not to use it. Sibling tool names suggest scope differences, but no explicit guidance is provided.

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