Create Vlan_group

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

The description adds context beyond annotations: mentions that it adds a new row, cautions about dry-run, and describes the return format (markdown/json). No contradiction with 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?

Very concise: two sentences plus a 'Returns' section. Every sentence adds value. Front-loaded with purpose.

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 no output schema, the description explains the return format and the need for caution (dry-run). Missing details on permissions or side effects, but sufficient for the complexity.

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 73%, so the schema already provides parameter details. The tool description does not add significant meaning beyond what is in the schema, so baseline 3 is appropriate.

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 ('Create') and resource ('new vlan_group in NetBox'), distinguishing it from sibling tools like netbox_get_vlan_group, netbox_update_vlan_group, etc.

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?

Explicitly advises to ask before calling and check if the user wants a dry-run, providing guidance on responsible use. Does not explicitly compare to alternatives, but the sibling set clearly separates create from read/update/delete.

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