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

With no annotations, the description carries full burden. It discloses a key behavior (resume's limitation) and a safety rationale. However, it does not explain other behavioral traits like what happens during pause (immediate?), stop (irreversible?), or if there are any side effects.

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: two sentences with no wasted words. It front-loads the purpose and then provides a specific constraint. Every sentence earns its place.

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, no output schema, and 0% schema coverage, the description is fairly complete. It explains the action parameter and a critical constraint. It could mention the optional host parameter, but overall sufficient for a simple 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?

Schema coverage is 0%, so description must compensate. It explains the action parameter with values 'pause|resume|stop', adding meaning beyond the schema. The host parameter is not described, which is a gap, but the essential parameter is well-covered.

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 indicates that the tool is for pausing, resuming, or stopping the current print, using specific verbs and resource. It distinguishes itself from siblings like start_print and printer_status by focusing on controlling an ongoing print.

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 provides critical guidance: 'resume only acts on a paused print — never on a stopped or errored job.' This tells when not to use resume. However, it does not explicitly state when to use pause or stop versus alternatives, but the context is implied.

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