Check EU AI Act Implementation Deadlines

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

The description adds behavioral details like returning days remaining and Digital Omnibus status beyond annotations. Annotations already declare readOnlyHint and idempotentHint, so the bar is lower. The description does not contradict annotations and adds some context, but lacks depth on data freshness or response structure.

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?

Two sentences with no waste. The first sentence states the main outputs, and the second gives a usage hint for the only_upcoming parameter. Front-loaded with key purpose.

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 output schema exists (not shown but mentioned), the description covers the main outputs and filtering behavior. For a read-only info tool, it is nearly complete. Missing details like possible error cases or pagination, but these are likely handled by the schema or are not critical.

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 100%, so baseline is 3. The description clarifies that only_upcoming filters out past milestones, adding meaning beyond the schema. However, area is only described in schema, not in description, so the description provides marginal added value.

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 clearly states the tool returns key implementation milestones and deadlines with days remaining, a next_milestone shortcut, and current status of the Digital Omnibus proposal. It distinguishes from siblings by focusing on deadlines, while other tools like classify_system or get_article serve different purposes.

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 implies use for checking deadlines but does not explicitly state when to use this tool versus alternatives (e.g., when to use get_obligations instead). It gives a hint about the only_upcoming parameter but no when-not or exclusion guidance.

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