dns_set_zone_options

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It clearly implies a mutation operation, but it does not explain whether the update merges with existing options or replaces them, what permissions are required, or whether there are side effects (e.g., triggering zone transfers). The description adds only minimal behavioral context beyond the fact that options are updated.

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 two sentences with the core purpose front-loaded ('Set configuration options for a zone') and the rest providing concise, non-redundant detail. Every sentence earns its place, and there is no excess verbiage.

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?

The tool has a simple parameter set (4 params, 1 required) with full schema coverage and no output schema, so the description need not explain return values. The description clearly communicates the purpose and the update semantics, making it sufficiently complete for an agent to select and invoke the tool. Minor gaps are in usage alternatives and side effects, but these are not critical given the overall clarity.

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 schema already provides 100% coverage with explicit descriptions for all four parameters, so the baseline is 3. The description adds value by framing the parameters as 'option key/value pairs to update', which implies partial update semantics and clarifies that only explicitly passed options are changed. This meaning goes slightly beyond the schema descriptions.

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 as setting configuration options for a zone, using a specific verb ('Set') and resource ('zone'). It also gives concrete examples (notify settings, zone transfer ACLs) that distinguish it from sibling tools like dns_enable_zone/dns_disable_zone or dns_zone_options.

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 basic usage instructions ('Pass the zone name plus any option key/value pairs to update') but does not explicitly state when to prefer this tool over alternatives such as dns_enable_zone/dns_disable_zone for the disabled flag, nor does it mention any exclusions or prerequisites. Usage is implied rather than explicitly contrasted with siblings.

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