Change Load Balancer Reverse DNS

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

Annotations already provide idempotentHint and non-destructiveHint. The description adds the valuable detail that null resets to default. However, it does not disclose permission requirements or other side effects.

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?

Two concise sentences, front-loaded with the core action, and zero wasted words.

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 rich annotations (idempotentHint, openWorldHint) and full schema coverage, the description is sufficient. It covers the crucial null-reset behavior, and no output schema is needed.

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 coverage is 100% and each parameter is well-described in the schema. The description does not add additional meaning beyond the schema; the null reset behavior is already captured in the schema's description of dns_ptr.

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 verb ('Change'), the resource ('reverse DNS entry for a load balancer's public IP'), and a specific behavior ('Set dns_ptr to null to reset'). It distinguishes from similar tools like change_dns_ptr by specifying load balancer.

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 usage context (setting PTR for load balancer IPs) but does not explicitly compare with sibling tools like change_dns_ptr or change_floating_ip_rdns, nor does it mention when not to use it.

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