Devicegroup Add

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

Annotations already declare destructiveHint=true and readOnly=false, so the safety profile is covered. The description confirms a mutation ('Add') but adds no context about duplicate names, acknowledged side effects, or authorization requirements; this is adequate but not enriched beyond annotations.

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 filler or repetition. It states the action and target immediately, earning a maximum structure 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?

For a complex nested-payload tool, the schema fully documents fields, required conditionals, and examples, and an output schema exists for return values. The only notable gap is lack of explicit usage routing, but the overall package is sufficient for correct 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?

Schema description coverage is 100% and the payload property schema contains detailed field descriptions, conditional requirements, and examples. The tool description itself adds no parameter-level meaning, so it relies on the schema, matching the baseline for high coverage.

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 clear verb ('Add') and a specific resource ('device group to LibreNMS'), making the primary action unambiguous. It does not explicitly contrast with sibling tools such as devicegroup_update or devicegroup_delete, so it falls short of full differentiation.

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 instead of devicegroup_update, devicegroup_delete, or devicegroup_add_devices. 'Add a new' only weakly implies creation of new groups, so an agent must infer the usage context.

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