update_dns_resolver_settings

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

Annotations already indicate this is a non-readonly, idempotent, non-destructive operation, and the description adds no further behavioral context. It does not mention that only provided parameters are updated or that apply_immediately controls when changes take effect, which are critical traits beyond the annotations.

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 wasted words. It concisely conveys the core action and resource.

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 the tool's complexity (8 optional parameters) and the existence of sibling tools like apply_dns_resolver_changes, the one-sentence description is insufficient. It omits key semantics such as partial-update behavior, the meaning of apply_immediately, and how this differs from applying pending changes. The output schema and annotations mitigate some gaps but not usage context.

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 provides 100% coverage with descriptions for all 8 parameters, so the description does not need to elaborate. The generic 'settings' wording adds nothing beyond the schema's field-level details.

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 the specific verb 'Update' with a clear resource ('DNS Resolver (Unbound) settings'), making the action unambiguous. It distinguishes from sibling getters like get_dns_resolver_settings, but does not explicitly differentiate from apply_dns_resolver_changes, which could be confused with this tool.

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 versus alternatives such as apply_dns_resolver_changes or get_dns_resolver_settings. It lacks any context about prerequisites, partial updates, or whether changes require a separate apply step.

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