Send Labels to Printer

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

Annotations provide basic info (not read-only, not destructive), and the description adds that labels are sent to a 'configured printer', implying a prerequisite. However, it does not disclose error states, what happens if printer is missing, or the response 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?

Two sentences, no filler. The main action is stated first, followed by an args list. Efficient and front-loaded.

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?

For a simple one-parameter tool with no output schema, the description covers the basics. But it lacks usage context and behavioral detail, making it minimally viable but not comprehensive.

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 100% with a brief description of the 'requests' parameter, and the tool description echoes it. However, the schema defines items as objects with no structure, so the description adds little beyond stating field names. Baseline 3.

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 'sends labels directly to a configured printer', using a specific verb and resource. It distinguishes from sibling tools like get_label_pdf which retrieve files rather than send to printer.

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 on when to use this tool versus alternatives like get_consignment_label_pdf or group_consignments_for_printing. No prerequisites or exclusions mentioned.

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