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

No annotations are provided, so the description carries the full behavioral disclosure burden. It states the content of the result but not the result shape (array vs object), and it does not explicitly indicate that this is a read-only operation or whether any authentication is needed. For a simple parameterless lookup this is a minor gap, but the absence of side-effect/read-only disclosure keeps it at a mid score.

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 wasted words. The first sentence enumerates the output content, and the second gives a direct usage hint. The structure is front-loaded and every sentence earns its place.

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 parameterless metadata lookup with no output schema and no annotations, the description covers the returned fields and the downstream consumer. It does not specify the exact return container or data types, but those details are not necessary for invoking the tool successfully. The description is nearly complete given the low complexity.

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 tool accepts zero parameters, so the schema already covers everything and the baseline is 4. The description adds relevant context by noting that the returned field keys are used as the keys for answers in submit_enquiry, which is helpful beyond the empty 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 clearly identifies the resource ('every field of the Dental Software Compare enquiry') and enumerates the returned attributes: key, label, type, required, help text, and allowed options. It lacks an explicit verb like 'lists' or 'returns', but the meaning is unambiguous. It also distinguishes itself from submit_enquiry by explaining how the field keys are consumed.

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 a workflow: call this tool to obtain field keys, then pass answers to submit_enquiry keyed by those keys. It gives a useful routing hint to a sibling tool but does not explicitly state when to use this instead of enquiry_describe or other siblings, nor does it provide exclusions.

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