DNS_validateDNSRecordsV1

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

No annotations provided, so description must cover behavioral traits. It mentions response codes (200 success, 422 validation error) and that it is a validation step. It does not explicitly state that it is a read-only operation, but the term 'validate' strongly implies no side effects. Missing information about any potential rate limits or prerequisites.

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 three sentences long, front-loading the purpose. It is concise and efficient, though could be slightly more structured (e.g., use bullet points for response codes). No waste of 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 complexity of the tool (validating DNS records with multiple parameters) and the absence of an output schema, the description is somewhat lacking. It explains the purpose and the HTTP status codes, but does not detail what the response body contains on success or error. It is sufficient for basic use but not fully 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?

Schema description coverage is 100%, so the schema already documents all parameters (domain, overwrite, zone) with descriptions. The tool description adds no extra meaning beyond the schema; it only talks about response codes. Therefore, 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 validates DNS records prior to update, using specific verb 'validate' and resource 'DNS records for selected domain'. It also distinguishes from sibling tools like DNS_updateDNSRecordsV1 by explicitly saying 'before 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 advises to use this endpoint before applying changes, which implies a workflow. However, it does not explicitly state when not to use it or mention alternatives. For example, it doesn't say that if you want to just fetch records, use DNS_getDNSRecordsV1 instead.

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