opnsense_dns_apply

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

No annotations are provided, so the description must disclose behavioral traits. It mentions 'reconfigure service' which implies potential service restart, but it does not state side effects, permission requirements, or idempotency. The description is minimal and lacks important behavioral context.

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, clear sentence that efficiently conveys the tool's purpose. It is front-loaded and concise, but could potentially include more detail without becoming overly long.

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 simplicity (no parameters, no output schema), the description is adequate but leaves gaps in behavioral context and usage guidance. It covers the core purpose but lacks completeness for an agent to fully understand implications.

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?

There are no parameters, and schema description coverage is trivially 100%. Per the rubric, 0 parameters warrants a baseline score of 4. The description adds no parameter information because none exist.

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 states the tool applies pending DNS/Unbound configuration changes by reconfiguring the service. It uses a specific verb ('apply') and resource ('pending DNS/Unbound configuration changes'), effectively distinguishing it from sibling apply tools like opnsense_fw_apply or opnsense_nat_apply.

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?

While the name and description imply usage after making DNS modifications, there is no explicit guidance on when to use this tool over alternatives or any prerequisites. The context of sibling apply tools suggests differentiation but does not provide clear when-to-use or when-not-to-use instructions.

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