librenms_get_device_info

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

No annotations are present, so the description must disclose behavioral traits. It only states the purpose without mentioning side effects, read-only nature, authentication requirements, or any constraints. The agent gains no insight into what happens when the tool is invoked beyond the basic operation.

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 sentence with no redundancy or extraneous information. It is concise and front-loaded, efficiently conveying the core function.

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 lack of an output schema, the description should provide more context about what 'detailed device information' includes to help the agent assess suitability. It also does not address any related concepts such as error handling or usage across different device types.

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?

With 0% schema description coverage, the description adds little value. It mentions that the tool operates 'by hostname,' which reiterates the parameter name, but offers no additional semantics such as format, examples, or constraints. The single parameter is required, but the description does not elaborate on acceptable values.

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 states the action (get) and the resource (detailed device information) and the method (by hostname). However, it does not distinguish from sibling tools like librenms_get_device_health or librenms_get_device_stats, which also retrieve device information but for specific aspects.

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?

The description provides no guidance on when to use this tool versus alternatives. It lacks any contextual cues about prerequisites, typical use cases, or when not to use it.

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