enable_dns_static

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

Annotations already declare idempotentHint=true and destructiveHint=false, covering the main behavioral concerns. The description adds no extra context beyond the purpose, but it does not contradict the annotations. Given the presence of annotations, this is adequate but not enriched.

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 concise sentence that immediately states the action and target. It is front-loaded, contains no filler, and every word contributes to the meaning. This is an excellent example of conciseness.

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 simple operation with two parameters and an output schema, the description provides the core purpose but lacks usage guidance and parameter semantics. The annotations and schema fill some gaps, but the description alone is not fully self-sufficient for a new agent. It is adequate for a straightforward tool, but has clear gaps.

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 0%, so the description must compensate for missing parameter details. It does not mention either parameter. While 'entry_id' is somewhat self-explanatory, 'device' is ambiguous, and the description offers no clarification about what device means or how it relates to the operation.

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 ('Enables') with a clear resource ('a static DNS entry'), distinguishing it from sibling tools like add_dns_static, remove_dns_static, and especially disable_dns_static. The purpose is unambiguous and directly states the action performed.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., that the entry must already exist), nor does it contrast with disable_dns_static or other DNS static entry operations. There is no usage context beyond the bare action.

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