dns_analyze_domain

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It implies a read-only analysis ('Analyze') but does not explicitly state that it is safe, non-destructive, or whether it requires special permissions. It also does not disclose what happens for invalid or non-existent domains, rate limits, or any side effects. This is a significant gap for an analysis 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 appropriately sized: a single sentence for the purpose, followed by a concise Args and Returns section. It is front-loaded with the core action and contains no filler or repetition. Every sentence contributes to understanding the tool's basic function.

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?

For an analysis tool, the description is incomplete. It does not explain what specific aspects of DNS configuration are analyzed (e.g., record correctness, security, TTL, DNSSEC) or what kind of recommendations are returned. While an output schema exists, the description should set expectations about the analysis scope and any input constraints. The lack of usage guidance and behavioral detail leaves an agent under-informed.

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 0% description coverage, but the description's 'Args' section explicitly explains the 'domain' parameter as 'The domain name to analyze.' This adds meaningful semantics beyond the bare string type. However, it is minimal and does not specify domain format, validation, or examples, so it falls short of a 5.

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 states a clear verb and resource: 'Analyze DNS configuration for a domain' and 'provide recommendations.' This distinguishes it from other DNS tools like dns_get_domain, dns_list_records, and dns_validate_record, which perform retrieval or validation. It is specific but could be more precise about what 'DNS configuration' analysis entails (e.g., records, security, propagation), so it doesn't fully earn a 5.

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. It does not mention any conditions, prerequisites, or comparisons to sibling tools like dns_validate_record or dns_get_domain. An agent has no context on what scenarios warrant analysis versus simple inspection or validation.

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