Update Vm_interface

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

The description adds context about PATCH semantics and id requirement, but does not elaborate on behaviors beyond annotations. Annotations already indicate readOnlyHint=false, openWorldHint=true, idempotentHint=true, and destructiveHint=true. The description adds value by clarifying that only provided fields change, but does not explain any potential side effects or auth needs. 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?

The description is two short paragraphs, front-loading the core semantics (PATCH, id, fields to change) and then output format. Every sentence provides value with no redundancy.

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 tool's complexity (14 parameters, nested objects), the description is somewhat complete by specifying update semantics and output. However, it does not explain relationships between parameters (e.g., bridge, parent, tagged_vlans) or describe the return structure beyond format choice. 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?

The description only adds minimal meaning to id (numeric) and response_format (output choices). With schema description coverage of 29%, many parameters like mtu, vrf, mode, bridge, parent, etc. are not explained in the description. The description does not compensate for the low 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 clearly states the tool updates an existing vm_interface in NetBox with PATCH semantics, specifying the verb 'update', the resource 'vm_interface', and the behavior. It differentiates from create/get siblings by emphasizing partial updates.

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 instructs to supply the numeric 'id' and only fields to change, implying when to use (update) versus create. It also explains the response_format parameter. However, it does not explicitly contrast with netbox_create_vm_interface or netbox_get_vm_interface, nor mention prerequisites like existing interface.

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