librenms_get_device_stats

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

With no annotations provided, the description carries the full burden. It describes a read operation but does not disclose permissions, rate limits, side effects, or return format. The lack of behavioral detail beyond 'Get' limits transparency.

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 very short (one sentence) and front-loaded with examples, but it sacrifices necessary details. It is concise but incomplete, earning a middle score.

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?

Given the simplicity of the tool (one parameter, no output schema), the description should clearly define what statistics are returned. Listing only three examples is insufficient; the agent does not know the full scope of the output. The tool is not well-documented for effective 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?

The schema has one required parameter (hostname) with no description in the schema itself (schema coverage 0%). The description does not explain what hostname is, its format, or how it relates to the statistics. The agent receives no additional context beyond the parameter name.

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 comprehensive device statistics') and provides examples (uptime, ports, availability), which clearly indicates the tool's purpose. However, it could be more precise about what 'comprehensive' includes, and it does not differentiate from sibling tools like librenms_get_device_health or librenms_get_device_ports.

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 alternatives such as librenms_get_device_health or librenms_get_device_ports. The description does not mention prerequisites, exclusions, or typical use cases, leaving the agent without context to choose appropriately.

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