customer_success_billing_inquiry_status

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

The description does not disclose side effects or read-only behavior. The name suggests a read-only inquiry, but the annotations set destructiveHint=true, creating a potential mismatch. The description also omits any warning about destructive effects, so it is not transparent about behavior.

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 concise and well-structured, with short paragraphs and argument definitions. No unnecessary fluff or redundancy, making it efficient to read.

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?

The description does not explain what the action returns (despite having an output schema), what specific inputs are expected, or how the result should be interpreted. It lacks essential context for an agent to fully understand the tool's behavior and outcome.

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?

Schema coverage is 0%, so the description must compensate. It provides only generic descriptions ('Free-text objective' and 'Optional JSON string of structured inputs') without explaining what content the message or inputs should contain. This is minimal and does not adequately clarify parameter usage.

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 runs a specific action ('customer_success domain agent action `billing_inquiry_status`') with a specific verb, and the name implies a status inquiry. However, it does not explain what the action actually does or how it differs from other domain-agent actions, so it is clear but not fully differentiating.

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 the many similar domain-agent dispatch tools. It mentions routing and scoping ('under your JWT, tenant, and company scope') but does not indicate appropriate use cases, prerequisites, or alternatives.

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