list_rate_alerts

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the operation is a listing and notes the plan requirement, but does not disclose the response format, whether pagination applies, ordering, or any side-effect behavior beyond being read-only.

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 entire description is one concise sentence with the main action front-loaded ('List the rate alerts') followed by an important prerequisite. There is no wasted text.

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 low complexity (zero parameters, simple list operation), the description is adequate but incomplete. It does not describe what a rate alert contains or the return shape, and there is no output schema to compensate; it also lacks sibling-based guidance.

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 tool has zero parameters, and the description correctly does not invent any. Per the rubric, a zero-parameter tool receives a baseline of 4, and the description adds no unnecessary parameter semantics.

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 ('List') and resource ('rate alerts'), scoped to 'this API key'. It clearly distinguishes itself from sibling tools like create_rate_alert and delete_rate_alert by describing a read/list 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?

The description implies usage (call this when you need to see existing rate alerts) and mentions a plan requirement, but it does not explicitly say when to prefer this over alternatives or provide exclusionary guidance. The usage context is inferable but not fully spelled out.

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