VPS_deletePTRRecordV1

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

No annotations are provided, so the description carries the full burden. It explains the effect (reverse DNS lookups will no longer return the hostname), implying the record is removed. However, it does not disclose if the action is irreversible or if there are prerequisites such as permissions or resource state.

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 consists of three sentences that efficiently convey the purpose, consequence, and usage. The third sentence is slightly redundant with the first, but overall it is concise and free of fluff.

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 tool's simplicity (2 parameters, no output schema), the description covers the core purpose and effect. However, it does not mention what the response looks like (e.g., success confirmation), leaving the agent with incomplete context for interpreting the result.

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?

The input schema has 100% coverage with descriptions for both parameters ('Virtual Machine ID' and 'IP Address ID'). The description does not add any extra meaning beyond what the schema already provides, so a baseline score of 3 is appropriate.

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 tool's purpose: 'Delete a PTR (Pointer) record for a specified virtual machine.' It also explains the consequence of the action: reverse DNS lookups will no longer return the hostname. This distinguishes it from its sibling VPS_createPTRRecordV1.

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 provides usage context: 'Use this endpoint to remove reverse DNS configuration from VPS instances.' It does not explicitly state when not to use or mention alternatives, but for a straightforward deletion, this is adequate.

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