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

No annotations are provided, so the description carries the behavioral disclosure burden. It does convey that the tool outputs a field list and that submissions happen elsewhere via submit_enquiry, suggesting a read-only metadata role. Still, it does not explicitly state that this tool has no side effects, describe how the field list is returned, or mention any limitations or error behaviors.

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 two tight sentences: the first front-loads the tool's output contents, and the second gives a concrete follow-up action. Every sentence earns its place with no redundancy or filler.

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 metadata retrieval tool without an output schema, the description provides enough detail about the returned field properties and the downstream submission mapping. It could be slightly more complete by naming alternatives or explicitly framing itself as the schema look-up tool, but nothing essential is missing for a basic call.

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 is empty and schema description coverage is 100%, so the 0-parameter baseline applies. The description adds relevant semantic context by explaining that the field keys returned here are the same keys to use in submit_enquiry, which is useful beyond the bare 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—the field definitions of the Compare Call Answering enquiry—and enumerates the content: key, label, type, required flag, help text, and allowed options. It lacks an explicit verb like 'retrieves' or 'lists', and it does not directly compare itself with sibling tools, so it falls just short of full clarity.

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 a practical usage pointer: answers should be passed to submit_enquiry keyed by field key, implying this tool is the source for constructing submissions. However, it does not explicitly state when to prefer this tool over siblings like enquiry_describe or compare_table, nor does it provide any when-not-to-use guidance.

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