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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the shape of the returned data and the downstream contract with submit_enquiry, which is genuine added context, but it never states that this is a read-only, side-effect-free inspection call with no rate limits or auth constraints.

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. The content of the payload is front-loaded and the integration hint follows as a single compact clause.

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?

With no output schema, the description steps in to enumerate the returned fields, which is exactly what is needed for a zero-parameter read tool. It is slightly thin on read-only semantics but otherwise gives an agent everything required to call it correctly.

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 no parameters, which is the baseline-4 case; there is nothing to document in the schema. The description usefully clarifies that returned field keys are the same keys expected by submit_enquiry, tying the zero-arg call to its purpose.

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?

States a specific resource and enumerates exactly what it returns (key, label, type, required flag, help text, allowed options) for a named enquiry, which is far more concrete than the vague sibling name dataset_columns-type tools. It does not differentiate itself from enquiry_describe, the obvious adjacent sibling, so it stops short of a 5.

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 implies the workflow ('Pass answers to submit_enquiry keyed by field key'), which tells the agent this is the discovery step before submitting. However there is no explicit statement of when to call this versus enquiry_describe, and no exclusion or prerequisite guidance.

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