iaas_updatevsphere_fabric_network

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

Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true and destructiveHint=false, so the safety profile is known. The description adds only the raw PATCH path, contributing no context about what is mutated, whether the body is a partial or full replacement, or any required permissions.

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?

It is short and front-loaded, but the second line restates the HTTP verb and path already present in the annotation title, so it does not fully earn its place. Little is left, but little is given.

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?

With a nested 10-property body object and no output schema, the description is thin: it does not say whether the body replaces or patches network configuration, nor what the response contains. The fully-documented schema keeps this at a minimum-viable level rather than inadequate.

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 nested body enumerates cidr, tags, gateways, DNS settings and more, so the schema carries the semantics. The description adds nothing about the id path parameter or which body fields are meaningful/optional beyond what is already documented.

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 specific verb and resource ('Update vSphere fabric network'), which is enough to identify the operation. It does not distinguish this from close siblings such as iaas_update_fabric_network (generic) or iaas_update_fabric_vsphere_datastore, so an agent must infer the vSphere-network specificity from the name alone.

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?

There is no statement of when to use this tool versus alternatives, no prerequisites, and no mention of when not to use it. The agent gets no routing guidance despite several near-identical update_* siblings in the list.

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