dns_intelligence__enumerate_dns

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

No annotations are provided, so the description carries the full burden. It does add real behavioral context about what is actively probed (zone transfer attempts, open recursion, DNSSEC algorithm weakness, CAA vs live cert), which tells the agent this performs live network queries rather than reading a cache. It omits, however, whether the operation is read-only/non-mutating, expected latency, rate limits, or failure behavior for unreachable domains.

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?

A single front-loaded sentence with the verb and resource first, then the check list. The parenthetical inventory is dense and each item is informative, though the run-on structure makes it slightly harder to scan than a short bulleted scope statement.

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 only two parameters, no output schema, and no annotations, the description is close to sufficient: it tells the agent what will be checked and that misconfigurations are detected. The missing piece is any hint of result shape or severity/verdict reporting, which the agent must discover at call time.

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 both parameters are already documented, including the nameserverProbe default and its four probe types. The description never references the nameserverProbe toggle, so it adds no semantics beyond the schema; baseline 3 applies.

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?

States a specific verb and resource ('Enumerate all DNS records for a domain') and then enumerates the exact check families covered (SPF, DMARC, DKIM, MTA-STS/TLS-RPT, MX, DNSSEC, CAA, nameservers). The breadth implicitly separates it from dns_intelligence__lookup_dns, but no sibling is named explicitly, so an agent must infer the boundary.

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 comprehensive scope hints that this is the full-audit call versus a simple lookup, but there is no explicit when-to-use/when-not guidance, no mention of alternatives like lookup_dns, audit_domains, or check_email_security, and no stated prerequisites (e.g. whether the domain must be resolvable).

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