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

No annotations exist, so the description carries the full burden, and it does disclose the shape of the returned data (field attributes and their allowed options). It never states that the call is read-only with no side effects, nor any auth or rate-limit behavior, which are the remaining gaps for a no-annotation tool.

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 waste, and the content of the response is front-loaded ahead of 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?

With no output schema and no annotations, the description compensates by enumerating the returned attributes and the key-based handoff to submit_enquiry. What is missing is a statement of read-only/side-effect behavior and any distinction from enquiry_describe, but for a zero-parameter lookup it is nearly 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, so per the baseline this scores 4. The description additionally documents the keying convention ('keyed by field key') that links the returned keys to submit_enquiry's input, which is meaningful 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 names a specific resource (the SEO for dentists enquiry fields) and enumerates exactly what each field carries (key, label, type, required flag, help text, allowed options), so the agent knows precisely what comes back. It does not, however, differentiate itself from the sibling enquiry_describe, which plausibly overlaps.

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 — call this to learn the field keys, then pass answers to submit_enquiry keyed by field key — which is genuine downstream context. But there is no explicit when-to-use statement and no contrast with enquiry_describe, so the routing is left to inference.

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