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

No annotations are provided, so the description carries the full burden, and it does disclose the shape of what comes back (key, label, type, required, help text, allowed options) plus how that output feeds submit_enquiry. It stops short of stating that the call is a non-mutating read or whether the field list can change between calls.

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 tight sentences: the first front-loads what the tool returns with a compact enumeration, the second gives the downstream action. No filler and nothing restated from the title.

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 parameters, the description must carry the return-value burden itself, and it does by listing every field attribute returned. It also closes the loop on how to use the result, so an agent can call it and act on it without further information.

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 is 4 and there is nothing in the schema to clarify. The description's mention of keying answers by field key is useful cross-tool semantics (for submit_enquiry) but is not a parameter of this tool.

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 (every field of the CRM agency enquiry) and enumerates exactly what each field contains: key, label, type, required flag, help text and allowed options. The retrieving verb is only implied by the noun-phrase framing, and it does not distinguish itself from the sibling enquiry_describe, which keeps it out of 5 territory.

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?

Usage is implied through the workflow hint 'Pass answers to submit_enquiry keyed by field key', which tells the agent this is the discovery step before submission. However, it never states when to call this instead of enquiry_describe, nor any prerequisite or exclusion, so guidance is only inferential.

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