device_route_count

Count device routes in a unit, with optional filters by device, network, or application, to assess routing configuration.

Instructions

Get the count of device routes in a unit.

B3.3/5.0

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Get' implies a read-only operation, but the description does not state whether filters affect the count, how the count is returned, or any permission or error considerations. This is minimal disclosure for a tool with no structured safety hints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no filler or repetition. Every word contributes to stating the action and the target resource, making it highly efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple count operation with fully documented parameters, the description conveys the core operation adequately. However, with no annotations, no output schema, and no alternative routing guidance, it leaves open the result shape and when to prefer related route tools. It is minimally viable but not complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so unit, device, network, and application are already documented in the schema. The description only echoes the unit concept and does not add extra meaning about filter behavior or parameter formats, landing at the baseline expected when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Get') and resource ('count of device routes') plus a scope ('in a unit'), making the operation unmistakable. This clearly differentiates it from sibling count tools like device_count and network_route_count, as well as from device_route_list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance about when to use this tool versus alternatives such as device_route_list or network_route_count, and no exclusions or prerequisites are mentioned beyond what the schema already states. An agent is left to infer the appropriate context from the name and description alone.

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