create-metering-job

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

No annotations are provided, so the description must fully disclose behavioral traits. It merely states 'Create a new metering job'—a tautology that reveals nothing about side effects, required permissions, asynchronous behavior, or post-creation steps. There is no additional context beyond the tool's name.

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 extremely short (six words) and front-loaded, but it is under-specified rather than concise. It restates the tool's name without adding value. For a creation tool with a complex nested payload, this brevity is not appropriate; it fails to earn its place by providing any useful 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?

Given the complexity of the tool (a create operation with a nested object parameter, no output schema, and no annotations), the description is wholly inadequate. It does not explain what a metering job is, what the payload must contain, how the job behaves after creation, or what response to expect. The agent is left without essential context to invoke the tool effectively.

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% parameter description coverage, but the only parameter ('job') is described as 'Metering job payload,' which is trivially uninformative. The tool description adds no clarification about the payload structure, required fields, or how the parameter should be used. The schema also allows arbitrary additional properties, so the agent gets no meaningful guidance on constructing a valid request.

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 function: 'Create a new metering job.' It uses a specific verb ('create') and resource ('metering job'), which distinguishes it from sibling tools like get-metering-job, get-metering-job-status, and other create tools (create-event, create-alert). No ambiguity exists 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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, use cases, or exclusions. Sibling tools for reading metering jobs (get-metering-job, get-metering-job-status) are not referenced, so the agent receives no context for selecting this tool appropriately.

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