get_page_journeys

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It does not state whether the operation is read-only, what data it returns, whether any side effects occur, or what authentication or plan requirements exist beyond the 'PRO+ plan' hint. This is far from adequate.

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 extremely short, but brevity is achieved by omitting essential information. It consists of two sentence fragments that convey almost no actionable detail, making it under-specified rather than efficiently concise.

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 no annotations, no output schema, and no behavioral context, this description is completely inadequate for an agent to understand the tool's purpose, output, or constraints. For a tool named get_page_journeys, one would expect at least an explanation of what a 'page journey' is and how it is represented.

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 tool has zero parameters, so there is nothing for the description to clarify about the input schema. Per the rubric, a baseline of 4 applies for 0-parameter tools. The description's lack of parameter detail is not a penalty here.

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 'User navigation paths' is a noun phrase that merely restates the tool name without a clear verb or action (e.g., 'gets', 'returns'). It does not explain what the tool actually does with these paths, nor does it distinguish this tool from sibling tools like get_visitor_activity or doc_neighbors.

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 for when to use this tool versus alternatives. The only additional context, 'PRO+ plan', indicates a plan restriction but does not help an agent decide when this tool is appropriate or what problem it solves.

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