dns_check_update

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

No annotations are provided, so the description carries the full burden. The verb 'Check' implies a read-only operation, but the description does not explicitly confirm that no changes are made, nor does it mention network dependencies or what the response will look like.

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 unnecessary words. It conveys all essential information about the tool's purpose without any filler.

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 no-parameter tool, the description states the core function, but it lacks an output schema, so it doesn't explain what the agent can expect as a result (e.g., a boolean, a version string, or an error). This leaves some ambiguity about how to interpret the outcome.

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 tool has zero parameters and an empty input schema, so there is nothing for the description to add. With zero params, the baseline is 4, which is appropriate here since the schema already fully covers the absence of parameters.

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's function: checking for a newer version of Technitium DNS Server. The verb 'Check' and the resource 'newer version' are specific, and it is distinct from sibling tools that manage zones, records, or settings.

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 gives a clear purpose but does not explicitly state when to use this tool versus alternatives. Since there is no direct sibling tool for update checking, the usage is implied but not elaborated with context such as 'before upgrading' or 'periodically.'

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