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

With no annotations provided, the description carries the full burden of disclosing behavioral traits, but it reveals nothing about side effects, required permissions, or return behavior. It is entirely uninformative about what the tool does.

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 very short, but this is under-specification rather than conciseness. A single vague phrase does not earn its place because it fails to communicate the tool's purpose, making it not useful.

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?

Given the absence of annotations, an empty schema, and no output schema, the description is the only source of information. It is completely inadequate for an agent to understand the tool's behavior or when to call it, especially among many sibling monitoring 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 tool has zero parameters, so per the rubric the baseline is 4. The description does not need to explain parameter semantics, and it does not contradict the empty schema. However, the description's vagueness slightly detracts from this score.

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 'Cloud monitoring obligations with cross-jurisdiction equivalents' is a noun phrase that does not specify a clear action or resource. It is vague about whether this tool lists, maps, or checks obligations, and it does not distinguish itself from sibling tools like cloud_incidents or cloud_status.

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 provides no guidance on when to use this tool or when to prefer alternatives. It offers no context, prerequisites, or exclusions, leaving the agent without any direction for tool selection.

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