Create PTR Record

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only states the action without covering side effects, idempotency, required permissions, or potential conflicts with existing records. This is a notable gap for a create operation, though the verb 'Create' at least implies a mutating action.

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, front-loaded sentence with no filler. It efficiently communicates the core purpose, though it sacrifices depth for brevity. Every word earns its place.

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 no annotations and no output schema, the description should explain prerequisites, side effects, and expected outcome, but it only states the purpose. It is insufficient for a mutation tool with three required parameters, leaving the agent without critical context about behavior and post-conditions.

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 fully documents all three required parameters with clear descriptions, achieving 100% coverage. The description adds no additional parameter semantics, so the baseline score of 3 is appropriate given the schema handles parameter meaning completely.

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 ('Create') and names the exact resource ('PTR (reverse DNS) record for a VPS IP'), which clearly distinguishes it from sibling tools like vps_ptr_delete and other DNS tools. This is unambiguous and directly states the tool's function.

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?

No explicit guidance on when to use this versus alternatives, but the purpose is implied by the name and description. It lacks mention of prerequisites or scenarios where other DNS tools (e.g., dns_get_records) would be more appropriate, but the intended use case is reasonably clear.

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