customer_success_billing_inquiry_status

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

Without annotations, the description carries full burden but discloses only the routing mechanism. It does not state whether this is a read or write operation, side effects, permissions, or idempotency, leaving significant behavioral ambiguity.

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 short with three sentences, front-loaded with the core action. However, the first sentence is somewhat redundant with the tool name, and the routing line adds context but is not essential.

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 no annotations and the presence of an output schema, the description fails to explain the action's specific business function, return values, or edge cases. It feels incomplete for an internal routing tool.

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 description adds basic semantics to the two parameters: message is a free-text objective and inputs is an optional JSON string. However, with 0% schema coverage, more detail about expected formats and examples is needed to fully compensate.

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 it runs a specific domain agent action for billing inquiry status, which is a clear verb+resource combination. However, it does not explain the action's business purpose in plain language, relying on the name's descriptiveness.

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 its siblings (e.g., customer_success_billing_triage). No context about prerequisites, scenarios, or exclusions is provided.

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