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

No annotations are provided, so the description carries the full burden. It discloses the content areas (MDR/IVDR, AI Act, NIS2, PSUR) but does not describe behavioral aspects such as whether the operation is read-only, the output format, pagination, or any side effects. This leaves significant gaps in understanding what the tool returns.

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 extremely concise, consisting of one short sentence and a list of topics. It is efficient and avoids verbosity, though it lacks a verb for structural completeness.

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?

With no output schema and no annotations, the description needs to explain what the tool returns or how it should be used. It only lists topic areas, leaving the agent uncertain about the actual output (e.g., a list of dates, explanations, or compliance statuses). This is inadequate for a tool with only a single optional parameter.

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 input schema has 100% coverage for the single 'year' parameter, including its default value (2026). The description adds no parameter-specific detail, but the baseline of 3 applies because the schema already fully documents the parameter.

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 identifies the resource as 'EU healthcare regulatory deadlines' and enumerates specific areas (MDR/IVDR transitions, AI Act obligations, NIS2, PSUR deadlines), which gives some clarity. However, it lacks a verb stating what the tool actually does (e.g., 'returns', 'lists'), making it a noun phrase rather than a clear action.

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 provided on when to use this tool versus siblings like mdr_compliance_check or ivdr_check. The description implies a general calendar of deadlines but gives no exclusion criteria or alternative recommendations.

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