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

With no annotations provided, the description carries the burden of behavioral disclosure. It usefully signals non-mutating behavior with '[READ]' and lists output fields, but it does not describe behavior around the default target resolution, invalid targets, empty results, or response format.

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 a single front-loaded sentence plus a one-line argument explanation. There is no filler, and the essential information is immediately visible.

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 simple read-only list tool with one optional parameter, it provides the core purpose, output fields, and target semantics. However, with no annotations and no output schema, it leaves some context unspecified: how the default target behaves, what the return structure looks like, and when to choose this tool over other PRTG listing tools.

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 input schema only shows that 'target' is an optional string with a default of null. The description adds real meaning by explaining it is a 'PRTG target name from config' and that omitting it uses the default, though it does not enumerate valid target names or explain where the config lives.

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 states a specific verb ('List') and resource ('monitored PRTG devices') and enumerates the returned fields (objid, device, host, status, group). This clearly distinguishes it from sibling tools that target sensors, groups, alarms, or other monitoring systems.

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 given about when to use this tool versus alternatives like prtg_sensors or prtg_groups. The '[READ]' prefix and resource name imply its use for device-level listing, but there are no explicit exclusions, alternatives, or conditions.

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