DNS_validateDNSRecordsV1

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

The description discloses response codes (200 for success, 422 for error), but without annotations, it fails to explicitly state that the tool does not modify DNS records. Behavioral traits like authentication or side effects are omitted, which is a gap for a validation tool.

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 concise with three sentences: purpose, response codes, and usage. It is front-loaded with the core function. No unnecessary repetition, though it could be slightly more efficient.

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 no output schema, the description covers return codes but omits details on what constitutes a validation success beyond the code, and lacks information on error structure. Adequate for a simple validation tool but could be more comprehensive.

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?

With 100% schema description coverage, the baseline is 3. The description adds no extra parameter details beyond what the schema provides; it only mentions 'domain' and 'zone' in context but not with additional semantics or examples.

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 before update, using verb 'validate' and resource 'DNS records' for a specific domain. It distinguishes from sibling tools like DNS_updateDNSRecordsV1 by emphasizing pre-update validation, but does not explicitly differentiate from other validation tools.

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 using the tool 'to verify DNS record validity before applying changes', which is clear usage context. However, it does not explicitly mention when not to use it or suggest alternatives, such as using DNS_updateDNSRecordsV1 after successful validation.

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