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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that this is the first question, but does not describe what the tool returns, whether it prompts the user, or how the response connects to subsequent checker tools. This is a significant gap for an executable tool.

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 sentence with no wasted words, and the key information—'first question' and 'Malta work permit checker'—appears early. It is appropriately sized for a tool with no parameters, though slightly more detail about the return behavior would be welcome.

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 zero-parameter tool, the description is minimally adequate: an agent knows this is the starting point of the decision guide and can call it without providing inputs. However, it does not explain what the agent should expect as output or how to proceed, which leaves some ambiguity given the sibling checker 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 input schema has zero parameters and schema description coverage is 100%, so there is nothing for the description to add about parameter semantics. The baseline of 4 applies because no parameter information is needed.

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 tool as the first question of the Malta work permit checker decision guide, making its role as an entry point clear. It does not explicitly state the action (e.g., 'starts' or 'displays'), but the title and 'first question' phrasing strongly convey the intended use.

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 gives no explicit guidance on when to use this tool versus alternatives. The phrase 'first question' implies it should be used at the start, but there is no mention of when not to use it or how it relates to checker_answer or checker_tree.

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