Check Printer MCP health

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description reinforces this with 'Does not print' and adds that path checks may be local or UNC, but says nothing about runtime, whether UNC probes require credentials or network access, or how results are reported. With annotations carrying the safety burden, this is adequate but not rich.

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 with zero filler, and the scope enumeration plus the non-printing constraint are front-loaded. Every clause carries information an agent needs.

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 no-output-schema read-only diagnostic, the description covers what is checked and the non-destructive nature well. It stops short of describing the shape of the health report or how partial failures on UNC paths surface, which would fully close the gap.

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% for the single 'paths' parameter, so the description must compensate. It does add meaning by noting the paths are optional and may be local or UNC, which aligns with required=0. It still does not explain expected path format, array behavior, or what happens when a path is unreachable, so compensation is partial.

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 (checks) and enumerates the exact resources inspected: Windows printing, default printer, PDF engine, Office apps, local storage, and optional local/UNC paths. The closing 'Does not print' separates it decisively from action-oriented siblings like print_paths and quick_print, so an agent can route correctly without opening a schema.

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 implies diagnostic usage and rules out printing, which is useful routing context. However, it never states when to run this versus alternatives such as get_print_settings or list_printers, nor any prerequisites or when-not-to-use conditions. Usage is inferred rather than specified.

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