domains_updateDomainNameserversV1

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

With no annotations provided, the description carries the full burden. It discloses the risk that improper configuration can make the domain unresolvable, which is a key behavioral trait. However, it does not detail whether the operation is idempotent, overwrite behavior, or response format, leaving gaps in transparency.

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 concise at three sentences, front-loading the primary action first, then a warning, then usage guidance. Every sentence adds value with no redundant or irrelevant information.

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?

Despite the warning, the description lacks critical context such as success/error responses, prerequisites (e.g., domain ownership), rate limits, and how to verify the changes. Given no output schema and no annotations, this incomplete context could hinder an agent's effective use.

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 coverage is 100% with descriptions for all 5 parameters. The description adds no additional meaning beyond what the schema provides, so baseline score of 3 is appropriate.

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 'Set nameservers for a specified domain,' using a specific verb and resource. It distinguishes from siblings like `VPS_setNameserversV1` by explicitly mentioning 'domain' and 'custom DNS hosting,' making its domain-specific purpose unambiguous.

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 includes a usage guideline: 'Use this endpoint to configure custom DNS hosting for domains.' It also warns about the risk of improper configuration. However, it does not explicitly state when not to use it or mention alternatives, though no direct alternative exists among siblings for domain nameservers.

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