Get scan metrics

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds meaningful context about what the tool returns: number of scans, detected threats, and other malware-scan statistics. It could mention behavior when Monarx is not installed, but that is a minor gap for a simple read endpoint.

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 first sentence is strong and front-loaded, but the third and fourth sentences are largely redundant ('useful for monitoring security status' and 'Use this endpoint to monitor VPS security scan results'). Condensing these would make the description tighter.

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 one-parameter read-only tool with full schema coverage, the description provides enough information to select and invoke it correctly. It explains what the metrics contain and why they matter, though an explicit note distinguishing it from VPS_getMetricsV1 would make it fully complete.

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 single required parameter virtualMachineId is already 100% documented in the input schema. The description only refers to 'a specified virtual machine' without adding constraints, formatting, or relationship details, so it does not meaningfully extend schema coverage.

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 uses a specific verb ('Retrieve') and names a precise resource: scan metrics for the Monarx malware scanner installed on a specified virtual machine. This clearly differentiates it from the broader VPS_getMetricsV1 sibling and other VPS tools.

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 gives clear intended use ('monitor VPS security scan results and threat detection') and implies the prerequisite that Monarx is installed. It does not explicitly exclude or compare against VPS_getMetricsV1, so an explicit alternative statement would improve it slightly.

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