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

With no annotations, the description carries the full behavioral burden. It discloses substantial return content (who receives details, consent wording, confirmation flow) and states nothing is bought or guaranteed, which is valuable given no output schema. It still does not explicitly declare this tool's own read-only/no-side-effect nature or that it takes no input.

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?

'Read first' is well front-loaded, but the text is wordy and repetitive, naming 'Background Check Quotes' twice and restating the enquiry concept. Some clauses, such as the re-explanation of what submit_enquiry does, could be tightened.

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-parameter documentation tool with no output schema, the description is reasonably complete: it covers purpose, free/no-purchase guarantees, and the kinds of content returned. It falls just short of fully specifying the response shape, which the absence of an output schema leaves partly to inference.

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 baseline is 4 and there is no parameter meaning to convey. The description correctly adds no param detail, which is appropriate here.

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 makes clear this is a descriptive/informational tool that explains what submit_enquiry does and returns consent wording, recipient details, and confirmation steps. It distinguishes this read-oriented role from the action sibling submit_enquiry. It loses a point because the phrasing is somewhat meta and repeats 'Background Check Quotes' rather than crisply stating the tool's own verb+resource.

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 for agents, which is useful implied guidance. However, it never names when to prefer this over enquiry_fields or other informational siblings, nor when it is unnecessary, so routing guidance is only partial.

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