books_bulk_print_bills

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

With no annotations, the description carries full responsibility for disclosing behavior. It does not explain what 'print' entails (e.g., generating PDFs, sending to a printer), whether it marks bills as printed, or any required permissions. The ambiguity is a significant gap.

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 concise, using only four words, and is front-loaded with the core action. It wastes no words, but it omits essential context, which is penalized in other dimensions.

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 tool has 3 parameters, no output schema, and no annotations, leaving the description as the sole source of behavioral information. It provides only a minimal purpose and fails to explain return values, side effects, or parameter usage, making it incomplete for reliable invocation.

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 description coverage is 0%, and the description does not mention any parameters. While the word 'bills' hints at the required bill_ids array, it adds no meaning for orientation or template_id, which the schema leaves to the caller to infer.

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 action ('Print'), the resource ('bills'), and the scope ('bulk'), which distinguishes it from sibling tools like books_get_bill or books_bulk_export_bills. The verb and resource are specific and unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention that it is intended for printing multiple bills at once, nor does it contrast with related tools like bulk export or sending invoice emails.

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