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

With no annotations and no output schema, the description carries the full burden, and it does disclose the returned shape: key, label, type, required, help text, and allowed options where present. It does not state auth requirements or whether the field list is static or configurable, but for a zero-param read that is a minor gap.

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, both earning their place: the first defines the payload contents, the second defines how to consume it. The most important information (what this returns and how it connects to submission) is front-loaded.

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-param introspection tool with no output schema, describing the returned field attributes is exactly the right content, and the linkage to submit_enquiry closes the loop. Slightly incomplete in that it never clarifies its relationship to enquiry_describe or whether the field set is per-form.

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, so the baseline of 4 applies. No parameter semantics exist to document beyond the implicit contract that field keys returned here are the keys expected by submit_enquiry.

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 resource precisely (the fields of the Web design Suffolk enquiry) and enumerates what each field record contains (key, label, type, required flag, help text, allowed options). An agent can tell it is a schema/introspection read rather than a submission, though the verb is implied rather than stated. It is distinguishable from submit_enquiry but not explicitly from enquiry_describe.

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?

It gives concrete workflow guidance: 'Pass answers to submit_enquiry keyed by field key,' which tells the agent this tool precedes submission and supplies the keys. No exclusion or boundary is drawn against the sibling enquiry_describe, so the when-not case is left implicit.

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