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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false. The description reinforces this with domain-specific phrasing — 'it does not send a message or place an order' — which usefully rules out the plausible-but-wrong assumption that a contact tool submits a message. It stops short of noting rate limits or return format, which is acceptable given the annotation coverage.

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 front-loaded sentence lists the payload contents, followed by a short clarifying clause about the absence of side effects. Every clause carries information; there is no filler or repetition.

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 input parameters and no output schema, the description carries the burden of describing what is returned, and it does so by enumerating email, location, response time, and the four page links. It could state the format of those links, but it is complete enough for an agent to select and call this tool correctly.

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 per the rubric the baseline is 4. There is nothing for the description to clarify on inputs, and it correctly does not invent any.

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 names the resource (contact info for Duffer Golf) and enumerates its contents — email, location, response time, and page links — so an agent knows exactly what comes back. It implicitly separates itself from siblings like get_faq and find_dealers by covering contact/reserve/shop/checkout links, though it never explicitly contrasts with them.

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?

Usage is only implied: an agent can infer it should call this when the user needs contact details or a link to reserve/shop/checkout. There is no explicit when-to-use statement, no condition selecting it over get_faq or find_dealers, and no exclusions.

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