plan_create_host

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

With no annotations, the description must disclose behavioral traits. It only hints that the tool 'plans' rather than executes, but does not explain what planning entails (e.g., whether it validates, generates an output plan, or has side effects). No permissions, rate limits, or additional behavioral context is provided.

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, concise sentence with no fluff. It is front-loaded with the action, but it is so brief that it omits important context. Still, every word serves a purpose, so it earns a slightly above-average score.

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 having an output schema, the description is incomplete for a tool with two required parameters, nested objects, and no annotations. It fails to explain usage context, parameter semantics, or the behavior of planning, leaving significant gaps for an agent to make a correct invocation.

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 has 0% description coverage and two required parameters. The description adds only a slight hint that 'host' expects a 'CreateHost body' and mentions 'panel' but does not clarify the structure or meaning of either parameter. This is insufficient given the lack of 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 states a specific action ('Plan creating a subscription host') and identifies the resource ('subscription host') and method ('using the panel's CreateHost body'). This distinguishes it from siblings like plan_create_core or plan_update_host, though 'plan' itself is not explicitly defined as a non-executing operation.

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 like plan_create_node or apply_change. The description does not mention use cases, prerequisites, or exclusions, leaving the agent without context for selecting this tool.

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