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

No annotations are provided, so the description carries the full burden of behavioral disclosure. However, it only describes what the calendar contains (milestones, deadlines, Art. references) and does not mention data freshness, whether it is static or dynamic, or any other behavioral characteristics. This is thin for a tool with no annotation support.

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 well-structured sentence that front-loads the core content (DORA compliance milestones and deadlines) and then adds a relevant detail (Art. references). There is no wasted wording.

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?

The tool is simple (no parameters, no output schema), and the description communicates its purpose adequately. However, it leaves out details like the time range covered, update frequency, or whether it returns a list of items, which would help a user understand what to expect. It is minimally viable but not rich.

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?

There are zero parameters, so the schema is trivially fully covered. The description adds a small piece of extra meaning by noting 'All Art. references included,' which is beyond the schema. The baseline for 0 params is 4, and the description does not detract from that.

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 provides DORA compliance milestones and upcoming deadlines for financial institutions, with a specific audience and content focus. It does not explicitly distinguish from siblings, but the sibling names are largely distinct topics (security threats, advisories), so ambiguity is low.

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 the tool is for checking DORA-related deadlines and milestones, but it does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives. The context is helpful but the guidance is only implied.

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