Create Aggregate

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

Annotations already indicate a write operation (readOnlyHint: false). The description adds that it 'adds a new row' and includes a dry-run warning, which is behavioral context not in annotations. However, it does not disclose side effects, permission needs, or other behaviors. This is moderate value.

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 short (3 sentences) and front-loads the purpose. The second sentence ('This adds a new row to NetBox') is slightly redundant with the first. Overall efficient but could be tighter.

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 create tool with 9 parameters and no output schema, the description explains the action, return format, and a dry-run consideration. It lacks details on prerequisites, what an aggregate represents in NetBox, or how it relates to other objects. Adequate but not thorough.

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 67%, leaving three parameters (tenant, comments, description) undocumented. The description does not add any parameter explanations, nor does it compensate for the missing schema descriptions. It relies entirely on the input schema, which is incomplete.

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 'Create a new aggregate in NetBox,' which clearly identifies the action and resource. It does not explicitly differentiate from sibling create tools (e.g., netbox_create_prefix), but the tool name and title already provide that distinction. Hence, purpose is clear but lacks sibling 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 only usage guidance is 'Ask before calling if the user wanted a dry-run.' This is a caution, not a guideline on when to use this tool versus alternatives like netbox_get_aggregate or netbox_update_aggregate. There is no comparison or context for selection.

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