defender_get_machines_by_vulnerability

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

The description adds no behavioral context beyond the annotations. It simply restates a listing operation; no pagination behavior, rate-limit implications, or other non-obvious traits are disclosed. It does not contraddict the readOnly/openWorld annotations, but it also contributes nothing extra.

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 with no filler. Every word earns its place and the core behavior is immediately clear.

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 lookup, the description plus schema is mostly complete. However, with no output schema, the description does not indicate the shape or cardinality of the returned device list, and it does not help an agent choose among the many similar sibling 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?

Schema description coverage is 100%, so the description does not need to document parameters. It adds no extra semantic detail beyond the schema, which is acceptable under the baseline for high 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 states a clear verb and resource: 'List the devices exposed to a vulnerability.' It conveys the core operation without being vague, though it does not explicitly differentiate itself from sibling tools like defender_get_machines_by_software or defender_get_recommendation_machines.

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 instead of sibling vulnerability-, machine-, or recommendation-focused tools. The intended usage is only implied by the tool name and short description.

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