billing_getCatalogItemListV1

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

No annotations provided. The description mentions pricing format (cents as integer) and that it retrieves available items. It does not discuss authentication, rate limits, or potential side effects. It's adequate for a read operation but could add more behavioral context.

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?

Two short paragraphs, front-loaded with purpose. The pricing detail is necessary and well-placed. Overall efficient with no wasted words.

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?

No output schema exists, so the description should explain return structure. It states 'Retrieve catalog items' but does not describe fields or pagination. It covers pricing format and usage but lacks details on what is returned, making it somewhat incomplete.

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 covers 100% of parameters with descriptions. The tool description adds no additional meaning beyond the schema (e.g., does not explain wildcard usage or category values further). Baseline 3 is 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 clearly states it retrieves catalog items available for order, explains pricing format, and explicitly says 'Use this endpoint to view available services and pricing before placing orders.' It distinguishes itself from sibling billing tools like getSubscriptionList or getPaymentMethodList.

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 explicitly states when to use the tool: 'before placing orders.' While it doesn't explicitly mention when not to use it or name alternatives, the context provides clear guidance. Siblings are different operations, so no confusion.

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