UltiMaker printer status

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the data scope (inventory plus active and queued jobs), but says nothing about permissions, pagination, or response shape that would go beyond the annotations.

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 sentences, front-loaded with the purpose and with no filler. The second sentence largely restates the readOnly annotation, so it is slightly redundant, but the definition stays tight.

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 zero-parameter read tool with no output schema, the description covers both the read-only nature and the contents returned (inventory, active and queued jobs). It could say a bit more about the shape of the job data, but it is adequate given the annotations.

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?

The tool takes zero parameters, so the baseline is 4 by rule. There is nothing parameter-related for the description to clarify, and it introduces no misleading parameter claims.

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?

States a specific verb (Read) plus the exact resource: the Cura Connect printer inventory along with its active and queued jobs. This clearly separates it from mutating siblings such as start_print, upload_gcode, and printer_api_write.

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 line 'This tool performs no printer write' implicitly signals that this is the read-side alternative to the write/print tools, but no explicit when-to-use, when-not-to-use, or named alternative is given. Usage is implied rather than stated.

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