billing_node_create

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

With no annotations provided, the description must carry the full burden of behavioral disclosure, but it only says 'create', which is barely more than the tool name. It does not explain what happens upon creation, such as whether a provider must already exist, whether an existing node is overwritten, or if billing starts immediately. This is a significant transparency gap for a mutation operation.

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 with no unnecessary words. It is as concise as possible for a simple create operation, even though it lacks depth.

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?

For a create operation with no annotations and no output schema, the description is overly sparse. It does not explain what a billing node is, any prerequisites (e.g., provider existence), or the meaning of the optional pricePerMonth in context. An agent would have to infer too much from the tool name and sibling list.

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 provides descriptions for all three parameters (nodeUuid, providerUuid, pricePerMonth) with 100% coverage, so the schema already carries the parameter meaning. The description adds no further semantic detail, making the baseline 3 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 states a specific verb and resource: creating a billing node. It clearly distinguishes this tool from siblings like billing_node_update and billing_node_delete through the 'create' verb. However, it does not explicitly differentiate itself from nodes_create, which could be confusing in the context of a large sibling list.

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 such as billing_node_update or billing_nodes_list. The description only states the action, providing no context about prerequisites or decisions on which tool to select. This leaves the agent without any routing information.

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