apply_virtual_ip_changes

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

Annotations already indicate idempotentHint=true, readOnlyHint=false, destructiveHint=false. The description adds the context that it applies pending changes related to apply_immediately=False, which is useful. However, it does not disclose any potential side effects or outcomes beyond what is implied, and with annotations covering the safety profile, a 3 is appropriate.

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 sentences, highly concise, and front-loaded with the core purpose. The second sentence adds crucial usage guidance without any fluff, earning a perfect score.

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 zero-parameter batch-apply tool, the description covers the essential purpose and usage trigger. It does not describe the output format, but the presence of an output schema likely covers that. It also does not list prerequisites beyond apply_immediately=False, which is the key one. Overall, it is adequately complete.

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?

This tool has no parameters, so the schema provides no content to elaborate on. The description does not need to add parameter meaning, and the baseline for zero parameters is 4. It correctly omits irrelevant parameter descriptions.

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 uses a specific verb and resource: 'Apply pending virtual IP changes.' It clearly distinguishes from other apply_* tools by specifying the virtual IP domain, and the pending aspect adds clarity. The second sentence further clarifies the operation is for batch-applying changes.

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 explicitly states when to use the tool: 'Use this after making changes with apply_immediately=False to batch-apply them.' This provides clear context, though it does not mention alternatives or explicitly say when not to use it. For a simple apply tool, this is sufficient.

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