Get Print Queue

get_print_queue

Check the print queue on macOS or Linux to view pending and active print jobs for any printer. Optionally specify a printer name to filter.

Instructions

Check the print queue for a specific printer or all printers. Shows pending and active print jobs.

Behavior3/5

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

No annotations provided, so description carries full burden for behavioral disclosure. Description indicates a read operation showing jobs, but does not detail potential side effects, auth needs, rate limits, or return format. Adequate but minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. Front-loaded with key purpose and scope. Every sentence serves a clear function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given low complexity (1 optional param, no output schema, no annotations), description covers core functionality. Lacks explicit mention of return structure but 'shows pending and active print jobs' implies list of job objects, adequate for simple query tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% for the single parameter. Description adds that printer is optional and defaults to all, matching schema. Adds little beyond schema, baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the verb 'check', resource 'print queue', and scope 'specific printer or all printers'. It distinguishes from siblings like get_config or list_printers.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies usage for checking pending/active jobs but lacks explicit when-to-use or when-not-to-use guidance compared to alternatives. No mention of prerequisites or exclusions.

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