apply_dns_resolver_changes

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

Annotations already indicate this is an idempotent, non-destructive write operation. The description adds the implementation detail of a POST request and the specific change categories affected, but does not disclose potential side effects like temporary service interruption.

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?

Two sentences front-load the primary action and provide a brief, informative explanation without redundant wording. The description is efficient and well-structured.

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 a zero-parameter tool with full annotations and an output schema, the description gives sufficient context about what changes are applied. It does not explicitly mention prerequisites for pending changes, but this is reasonably implied. Slight room for improvement in usage guidance.

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 zero parameters, so the description correctly requires no input. With no parameters to document, the baseline score of 4 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?

The description clearly identifies the tool's function: 'Apply pending DNS Resolver configuration changes' and specifies the scope by listing host override, domain override, access list, or settings changes. This distinguishes it from sibling apply_* tools such as apply_dns_forwarder_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 usage context is implied: the tool activates pending DNS Resolver changes, but the description does not explicitly state when to call it relative to making configuration changes or mention alternatives. It would benefit from stating that it should be used after modifying DNS resolver settings, not for DNS forwarder changes.

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