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

The readOnlyHint annotation already signals a safe read operation. The description adds that results are per-visit and include a human/bot field, which is useful behavioral context. However, it does not disclose defaults for days/limit, ordering, pagination, or whether bot visits are included by default.

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 compact sentence with a clear front-loaded scope and a colon-separated field list. It is free of filler, though very terse.

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?

For a three-parameter tool with no output schema, the description omits essential input semantics (especially required 'site' and the meaning of 'days'/'limit') and does not position the tool against its siblings. The returned-field list helps, but it is not enough for correct invocation.

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%, so the description carries the full burden for explaining the parameters. It does not explain 'site', 'days', or 'limit' beyond a vague sense of 'recent' and 'individual visits'. The description mostly enumerates output fields rather than input semantics.

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 identifies the resource as recent individual visits and enumerates the fields returned (entry page, path, country, device, human/bot). This distinguishes it from aggregate siblings like get_stats or get_timeseries, but it does not explicitly name any alternative.

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 given on when to use this tool versus siblings such as get_breakdown, get_realtime, or get_bot_report. The only implied signal is 'individual' versus aggregate reports, but there are no explicit conditions, exclusions, or alternatives.

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