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

No annotations are present, so the description carries the burden, and it does disclose meaningful behavioral context: nothing is bought, ordered or paid, no quote is guaranteed, and the operation is free. It also enumerates what is returned (recipients, consent wording, confirmation mechanism), though it does not state that this describe call itself has no side effects.

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?

It is short and front-loads the sequencing cue, but the capitalized emphasis ('ENQUIRY', 'Read first.') and the trailing 'Also returns...' clause make it read more like marketing copy than a crisp definition. Every sentence roughly earns its place, yet the phrasing is not tight.

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 must explain return content, and it does list the three things returned. An agent has enough to decide whether to call it before submit_enquiry, though it does not say how those returns are structured or whether this tool is idempotent.

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?

Zero parameters, so the baseline is 4 under the rubric. The empty schema leaves nothing to clarify, and the description correctly avoids inventing parameter semantics.

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 uses a clear verb+resource framing ('states plainly what submit_enquiry does') and identifies itself as a read-first documentation tool, which separates it from submit_enquiry and enquiry_fields. It is slightly muddled because the subject of most sentences is the sibling tool rather than this tool, but an agent can still tell what it gets back.

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?

'Read first' gives an explicit ordering cue relative to submit_enquiry, and the framing implies this is a pre-submission orientation step. It stops short of stating when-not to use it or naming enquiry_fields as an alternative for field-level questions.

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