hosts_create

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'Create a new host' – which is self-evident. It does not mention persistence, side effects, required permissions, idempotency, or any consequences of the mutation. This is a significant gap for a creation tool.

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 directly states the tool's purpose. It is front-loaded with the action and resource, with no filler or repetition. It earns its place and is appropriately sized for a simple action statement.

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 rich schema, the description lacks high-level context about what a host is, what is required to create one, or what the agent should know about the implications of the action. With no output schema and no annotations, the description alone is insufficient to fully guide an agent toward a correct invocation, especially given the complex nested parameters and enums.

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 has 100% description coverage for all 21 parameters, so the baseline is 3. The description adds no parameter-level meaning beyond what the schema already provides, but it does not need to because the schema is thorough. It neither compensates nor detracts.

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 states a specific verb ('Create') and resource ('a new host in Remnawave'), clearly distinguishing this from sibling tools like hosts_update, hosts_delete, and hosts_list. The action is unmistakable and there is no ambiguity about what the tool does.

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. There is no mention of prerequisites, when hosts_create should be preferred over hosts_bulk_create or hosts_update, or what scenarios call for it. The description simply states the action without contextual direction.

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