update_virtual_ip

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

The description adds no behavioral context beyond what annotations already provide. It does not disclose that changes may require an apply step, nor does it mention the behavior of apply_immediately. With readOnlyHint=false and destructiveHint=false already signaling a mutation, the description merely repeats the obvious 'update' action without additional transparency.

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 a single, concise sentence that front-loads the action and target. It contains zero superfluous words and is instantly scannable.

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?

Despite a rich schema and output schema, the description omits crucial operational context: how to discover existing IDs, whether changes apply immediately or require separate apply action, and any prerequisites (e.g., a VIP must already exist). For a mutating tool with 12 parameters, this is insufficiently contextualized.

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%, so the schema already documents all 12 parameters. The description adds no extra semantics beyond identifying the required vip_id. This meets the baseline for schema-covered parameters but does not enhance understanding of parameter relationships or defaults.

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 'Update an existing virtual IP by ID' uses a specific verb ('Update') and resource ('virtual IP'), clearly distinguishing it from sibling tools like create_virtual_ip, delete_virtual_ip, and search_virtual_ips. The 'by ID' qualifier precisely defines the operation scope.

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 guidance on when to use this tool versus alternatives. It does not mention that vip_id should come from search_virtual_ips, nor does it clarify the relationship with apply_virtual_ip_changes or the apply_immediately parameter. The description solely states the action without any usage context.

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