netbox_update_object

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively communicates the partial-update behavior ('Only the fields included in `data` are changed') and the important runtime constraint ('Disabled when the server is running in read-only mode'). The description does not contradict any annotations because none exist. It could add more about error handling or idempotency, but for a PATCH-style operation it covers the key behavioral aspects.

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 concise, front-loaded with the core purpose, and then logically lists the parameters in an Args block. Every sentence earns its place, and the structure makes the parameter meanings easy to scan. There is no redundant filler.

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?

The tool is a mutation operation with three required parameters, one of which is a dynamic object, and an output schema is present. The description covers the operation semantics, parameter meanings, and the read-only mode caveat. Return value details are not needed because an output schema exists. Minor gaps such as failure behavior are not covered, but the essential information for selecting and invoking the tool is present.

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 0%, so the description must fully compensate for the lack of parameter documentation. It does: endpoint is defined as an 'app.endpoint' string with the clear example 'dcim.devices', id is described as 'The object's numeric ID', and data is explained as 'Field values to change.' This provides meaningful guidance beyond the bare type information in the input schema.

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: 'Partially update an existing object at a NetBox endpoint.' The verb 'partially update' distinguishes it from create and delete siblings, and 'existing object' signals it is not for creation. A sibling like netbox_create_object is clearly differentiated even without opening its schema.

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 implies when to use the tool: when an object already exists and only some fields need changing, as stated by 'Only the fields included in `data` are changed.' However, it does not explicitly contrast with sibling tools like netbox_create_object or netbox_delete_object, nor does it state when not to use this tool. The usage context is present but left to inference.

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