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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description is not carrying the safety burden alone; it still adds real value by enumerating what is not persisted or sent and by explaining that the buyer completes contact details on the website. It stops short of describing the lifetime or validity of the generated link/draft, which matters for a non-idempotent prepare step.

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 positive capability first, then the explicit non-capabilities and the scoping rule. Every clause carries information an agent needs and nothing is repeated.

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 9 parameters, zero schema descriptions, and no output schema, the description leaves the agent guessing about field semantics and about the structure of the returned draft/link. It covers the safety and scope story well but is materially incomplete for a tool of this input complexity.

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?

Schema description coverage is 0% across 9 parameters, so the description must compensate and largely does not. The only implicit parameter guidance is that contact details are deliberately excluded, which helps confirm the shape of the input but says nothing about product_id, request_type enum values, or how quantity/packaging/specifications are expected to be formatted.

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 specific verb and pair of artifacts: 'Prepare an editable HTR inquiry draft and official website confirmation link.' An agent immediately knows the output is a draft plus a link, not a submitted inquiry. It does not name the closely related sibling validate_inquiry, so sibling routing still requires inference.

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 negative list ('DOES NOT submit, store the draft, send email, create a CRM record or verify an email') effectively rules out using this tool when the agent wants an actual submission, and 'Collect only procurement requirements' scopes inputs. However, it never says when to prefer this over validate_inquiry or what the expected sequence between them is.

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