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

No annotations are provided, so the description carries the full disclosure burden. It does describe the returned payload in detail, which is useful, but it says nothing about whether this is a cached/static contract, whether auth or a live dataset session is needed, or whether the field set can change over time. For a read-only metadata lookup that is acceptable but not rich.

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, zero filler, and the payload description is front-loaded before the downstream usage hint. Every clause 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?

There is no output schema, so the description must carry the return shape, and it does enumerate the per-field contents. It leaves the container structure (list vs keyed map, ordering) slightly ambiguous and omits any error/empty case, but for a parameterless getter it is close to sufficient.

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 takes zero parameters and the schema is empty, so there is nothing to disambiguate; per the baseline, 4 is appropriate. The description correctly implies the call is argument-free and instead defines the shape of the returned keys used downstream.

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 names the concrete resource (the Buffrota enquiry's fields) and enumerates exactly what each field record carries: key, label, type, required flag, help text and allowed options. That is far more specific than a tautology, but it never contrasts itself with the sibling enquiry_describe, so an agent must infer which of the two metadata readers it wants.

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 second sentence supplies a clear workflow context -- use the field keys returned here as the keys when calling submit_enquiry. That tells the agent why and when to reach for this tool. It stops short of exclusions, e.g. it never says how this differs from enquiry_describe or that it takes no arguments.

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