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

No annotations are present, so the description must carry the full burden. It provides no behavioral details beyond the fact that printing occurs. It does not disclose side effects, system interactions (e.g., printer availability), or whether the operation is blocking.

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 at three words, which is efficient. It is front-loaded with the action. However, it might be too minimal to provide sufficient context.

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 the lack of annotations and output schema, the description is incomplete. It does not explain the behavior of optional parameters (e.g., printDialog=false) or the consequences of different printer presets. A more complete description would include these details.

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?

All three parameters have descriptions in the input schema (100% coverage), so the description does not need to add detail. The description itself adds no extra semantic value beyond what the schema already provides, which is adequate.

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 'Print a book' clearly states the action and resource. It is a specific verb+noun, and no sibling tool appears to perform the same function (other tools export or package, not print). However, it lacks any additional scope or context to distinguish it further.

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 such as export tools. There is no mention of prerequisites, recommended scenarios, or situations where printing is not appropriate.

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