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

No annotations exist, so the description carries the behavioral burden, and it does add real context: nothing is bought, ordered or paid, no quote is guaranteed, and the process is free. It also previews the returned content (recipients, consent wording, confirmation). It does not explicitly state read-only-ness beyond the 'Read first' hint.

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 with the key directive ('Read first') front-loaded; every clause carries information about scope or returns. Slightly dense but no wasted filler.

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?

There is no output schema, so the description must convey return content, and it does name the three things it returns (who receives details, consent wording, confirmation method). Adequate for a zero-parameter read tool, though an agent cannot tell exactly how that content is structured.

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 there is no parameter semantics to document and the baseline of 4 applies.

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?

States a clear verb and resource: it describes the enquiry flow, specifically what submit_enquiry does and what the person receives (details recipients, consent wording, confirmation path). It is distinguishable from a generic read tool, but it never contrasts itself with the sibling enquiry_fields, which likely also describes enquiry data, so sibling differentiation is missing.

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 opening 'Read first.' cues that this should be consulted before submit_enquiry, which is useful implied sequencing, but there is no explicit when-to-use/when-not statement and no named alternative tool.

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