create_dns_domain_override

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

The annotations indicate readOnlyHint=false and destructiveHint=false, which is consistent with a create operation, but the description provides no additional behavioral context (e.g., whether changes are reversible, if it requires prior DNS resolver configuration, or how it affects DNS resolution). It simply restates the action without explaining the impact.

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, compact sentence that is easy to scan. However, it is under-specified given the complexity of the tool; it is concise but not rich enough to be fully effective. It earns points for being front-loaded and brief, but could be expanded without losing 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?

Given the tool has 5 parameters and related sibling tools, the description is incomplete. It doesn't explain what DNS domain overrides are, when they should be used, or how they interact with other DNS settings. The output schema and parameter descriptions cover some details, but the tool's purpose and selection context are missing, making it insufficient for an AI agent to confidently choose this tool.

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?

All five parameters have descriptions in the schema (100% coverage), so the schema carries the load for parameter semantics. The description adds no extra information about parameters, such as how apply_immediately interacts with the override or what forward_tls_upstream means in this context. It stays at the baseline because schema coverage is complete.

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 action ('Create') and the resource ('a DNS domain override entry'). It is distinct from update/delete/search operations, but it doesn't differentiate between DNS domain overrides and related concepts like DNS host overrides or forwarder host overrides, so it stops short of fully distinguishing among sibling tools.

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?

There is no guidance on when to use this tool versus alternatives like create_dns_host_override or create_dns_forwarder_host_override. No context, prerequisites, or exclusions are mentioned. The schema and sibling list imply ambiguity, but the description does nothing to resolve it.

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