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

No annotations, so the description carries the burden; it does disclose that the documented endpoint has side effects and a defined response shape, which is useful. However, it doesn't state that calling this tool itself is a read-only documentation lookup, nor anything about auth or rate limits.

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?

A single dense sentence that front-loads the purpose before the content list and alternatives. Slightly packed with parentheticals, but nothing is redundant.

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 does the right thing by listing what the returned reference contains (contact fields, service keys, response shape, side effects). Only the read-only nature of the tool call itself is left implicit.

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 nothing for the description to disambiguate; baseline 4 applies. The description correctly frames the output as a reference document rather than implying any input.

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 concrete resource (the public quote endpoint's HTTP contract) and enumerates its contents: required contact fields, service keys, response shape, side effects. It doesn't explicitly contrast itself with get_pricing_ranges or list_services, so an agent must infer that this is the 'exact quote' path versus rough pricing.

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 word 'EXACT' and the mention of 'human-facing alternatives (quote page, online booking, phone)' imply when this reference applies, but there is no explicit when-to-use rule or named sibling alternative such as 'for ballpark figures use get_pricing_ranges'.

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