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

No annotations are provided, so the description must carry the full burden. It does not disclose what the tool actually does (e.g., read-only lookup, mutation, required authentication) or what the response contains, leaving behavior completely opaque.

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 concise sentence with no filler, but it is under-specified. Being short is good, but it sacrifices the clarity needed for a useful tool description.

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 compliance-check tool with no output schema, the description should explain what information is returned (e.g., risk class, notified body, deadlines). It only lists topics without describing the tool's behavior or return value, leaving the agent with insufficient context.

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 coverage is only 50% (risk_class has a description, device_name does not). The description mentions risk class A-D but does not explain how risk_class or device_name are used in the compliance check, adding little value beyond the schema.

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 names the topic (EU IVDR 2017/746 compliance) but lacks a specific action verb. It does not clarify whether the tool checks compliance, provides requirements, or returns a classification, making the purpose vague and not clearly distinct from sibling tools like mdr_compliance_check.

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?

There is no guidance on when to use this tool vs alternatives. It does not mention prerequisites, exclusions, or situations where another tool (e.g., mdr_compliance_check) would be more appropriate.

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