host_create

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

With no annotations, the description bears the full burden of behavioral disclosure. It does not mention whether the operation is destructive, requires special permissions, is idempotent, or what effects creation has on existing DNS configurations. The minimal statement 'Create a nameserver host' does not reveal any behavioral traits beyond the core action.

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, focused sentence that immediately states the action. It is concise and front-loaded, with no irrelevant details or repetition.

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 simplicity of the tool and complete schema coverage, the description is somewhat adequate. However, since there is no output schema and no annotations, the description does not explain return values, error conditions, or prerequisites (e.g., domain must exist), leaving the agent with an incomplete picture for a mutation operation.

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 input schema already describes both parameters (host and ipList) with 100% coverage, so the baseline is 3. The description adds no extra meaning beyond what the schema provides, such as format constraints, default values, or dependencies between the 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 purpose: 'Create a nameserver host (glue record)'. The verb 'Create' and the resource 'nameserver host' are specific, and the parenthetical 'glue record' further clarifies the domain-specific operation, distinguishing it from other DNS-related tools like dns_record_add or host_update.

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?

No guidance is provided on when to use this tool versus alternatives such as host_update, host_delete, or dns_record_add. The description simply states what it does, leaving the agent to infer usage context from the tool name alone.

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