Behavior2/5

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

With no annotations, the description carries the full behavioral disclosure burden, but it only says 'List... alerts' without describing pagination, alert scope, default top behavior, required permissions, or whether this is a read-only operation beyond the verb. It is minimally informative but not misleading.

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

Conciseness4/5

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

The description is one compact sentence with no filler and front-loads the verb and resource. The parenthetical 'v2' is terse but may leave the agent uncertain about what version-specific behavior is implied.

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

Completeness2/5

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

For a tool with two undocumented optional parameters and no output schema, this description is too thin to be complete. It leaves the agent without guidance on filter syntax, return shape, or relation to related security tools.

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

Parameters1/5

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

Schema description coverage is 0% and the description provides no explanation of 'top' or 'filter'. Since the schema itself has no descriptions, the description needed to compensate, but it does not add any meaning beyond the parameter names.

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?

The description starts with a specific verb ('List') and a clear resource ('Microsoft 365 Defender alerts'), and the parenthetical 'v2' signals an API version. This distinguishes it from sibling tools like list_security_incidents and get_security_alert without needing to open the schema.

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

Usage Guidelines2/5

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 related alert/incident tools, nor any mention of prerequisites or alternative tools. The intended use is only implied by the name and resource.

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