get_app_route_statistics

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It implies a read-only statistics retrieval, but does not state whether the stats are real-time or cumulative, what time window applies, whether device connectivity is required, or what the response includes.

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 with no wasted words. It efficiently states the resource and scope.

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 simple one-parameter read tool, the description is minimally sufficient to identify the operation. However, with no annotations and no output schema, it leaves behavioral details and expected return information implicit.

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 single device_id parameter is fully documented in the schema as accepting a device ID or system-ip. The description does not add meaning beyond the schema, so the high schema coverage baseline of 3 applies.

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 states a specific verb and resource: get application-aware routing statistics, clarified as tunnel stats, for a device. It is clearly distinct from generic siblings, though it does not explicitly contrast with closely related tools like get_app_route_sla_class or get_sdwan_stats.

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?

There is no guidance on when to use this tool versus related routing/statistics tools, nor any stated prerequisites such as device reachability or required permissions. The phrase 'for a device' implies context but does not provide usage guidance.

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