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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so the safety profile is covered. The description adds behavior beyond them: newest-first ordering, status rendered as /quotes shows it, inclusion of the resulting quote, and the unauthenticated case where the connection prompts a sign-in on printdash.io.

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 sentences, no filler, with the resource identity and ordering front-loaded and the auth caveat second. Every clause conveys something the agent would otherwise have to discover at call time.

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?

An output schema exists, so return shape needs no explanation, and the description still covers ordering, status semantics and the auth failure mode. It is sufficient to call correctly; only the sibling-selection guidance is thin.

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 schema has zero parameters, so the baseline is 4 and no parameter explanation is owed. The phrase 'current buying context' usefully implies the scope is set elsewhere rather than by this call.

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 resource ('list_quote_requests') scoped to 'the customer's custom quote requests in the current buying context', which separates it from the singular get_quote_request and from list_quotes. It never names those siblings, so the differentiation must be inferred from the resource wording alone.

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?

Mentions the 'current buying context' constraint, implicitly tying usage to set_context, and the sign-in prerequisite is stated clearly. There is no explicit guidance on when to choose this over list_quotes or get_quote_request, so the agent must reason about the distinction.

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