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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds genuinely new behavioral context beyond that: sign-in is required and the call needs buyer:read scope, including the OAuth discovery endpoint. It omits result ordering and whether the limit is the only pagination control, which keeps it from a 5.

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?

The purpose is front-loaded in the first sentence, which is good. But 'Requires buyer read access' and 'Requires sign-in with buyer access' are near-duplicates of the same prerequisite, and the OAuth discovery URL is low-value detail for most invocations, so the text is padded relative to its content.

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 values need not be explained, and the auth prerequisites are explicitly stated. For a one-parameter read-only list tool, the remaining gap (no mention of result ordering or how the limit relates to total results) is minor.

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 100% and the single limit parameter (1-50, default 20) is fully documented in the schema. The description adds no further meaning such as ordering or counting semantics, so the baseline of 3 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?

The description states a concrete verb and resource (list quote requests) plus the scope ('for the signed-in buyer'), which cleanly separates it from seller-facing siblings like list_seller_orders. It does not, however, differentiate itself from get_quote_requests or get_quote_status, so an agent must infer which quote-listing tool applies.

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 implied by the 'signed-in buyer' framing and the buyer:read scope requirement, so an agent can tell it only applies to buyer contexts. There is no explicit statement of when to prefer this over get_quote_requests or when not to use it, leaving the sibling choice unresolved.

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