Create DNS Record

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

The description only states the creation operation without disclosing any behavioral traits (e.g., immediate effect, permissions needed, rate limits). The annotation 'openWorldHint' is present but uninformative about behavior.

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 but lacks structure or front-loading of critical information. It is not verbose, but could be more helpful with added context in a similar length.

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 has 5 required parameters and an output schema, the description is too brief. It does not explain the return value, prerequisites, or any constraints, leaving the agent to infer from the schema alone.

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?

Since the input schema covers 100% of parameter descriptions, the description adds no extra meaning. It correctly identifies the action but does not elaborate on parameter usage beyond what the schema provides.

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 action ('Create') and the resource ('a new DNS record for a domain'), which is specific and distinguishes it from sibling tools like delete and update.

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 no guidance on when to use this tool versus alternatives (e.g., update or delete), nor any prerequisites or context for using the tool effectively.

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