Update DNS Records

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

With no annotations, the description carries the full burden of behavioral disclosure. It implies a mutation via 'update/replace' but does not state whether this replaces the full set of records, whether the operation is destructive/reversible, or what response or errors to expect. The word 'replace' hints at overwrite semantics but is not explicit.

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, front-loaded sentence with no filler. It quickly communicates the verb and resource, earning every word it uses.

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?

The tool has no annotations or output schema, and the description omits critical context about replace-all behavior, validation, and relation to sibling DNS tools. While the schema covers parameters, the overall description is too minimal for an agent to safely invoke this potentially destructive operation without additional assumptions.

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 schema provides descriptions for both 'domain' and 'records' with 100% coverage, so the description does not need to add parameter-level detail. However, the description adds no extra meaning beyond the schema, not even clarifying that 'records' is the complete replacement list.

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 uses a specific verb ('Update/replace') and identifies the resource ('DNS records for a domain'), making the core action clear. However, it does not explicitly disambiguate from sibling operations like dns_reset_records or batch_dns_update, and it leaves ambiguous whether this replaces the entire record set or just modifies given records.

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?

No guidance is provided on when to use this tool over alternatives. The description does not mention dns_get_records, dns_delete_records, dns_reset_records, or dns_validate_records, and it offers no prerequisites or exclusions.

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