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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds that records include status/customer/location/total/expiry, which is useful given no output schema, but it says nothing about pagination behavior, default sort, result volume, or rate limits that matter for a 9-parameter list tool.

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 short sentences, zero filler, with the resource and returned fields front-loaded before the endpoint reference. Nothing is wasted and nothing is buried.

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 optional filter parameters, 100% schema coverage and a readOnly annotation, most of the burden is handled elsewhere and the description supplies the missing return-field information. However, for a list tool with no output schema it should indicate pagination/total-count semantics, which it omits.

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% with 9 well-documented parameters including enums for sort, sortOrder and status values, so the schema carries the semantics. The description adds no parameter-level detail (e.g. that status accepts a comma-separated list), so baseline 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?

States a specific verb and resource ('List quotes') and enumerates what each record carries (status, customer, location, total, expiry), plus the underlying endpoint GET /quote. It is clearly a collection read, distinguishable by name from the sibling servicetrade_get_quote, though that sibling is never named explicitly.

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?

No explicit when-to-use / when-not-to-use guidance is given; the agent must infer from the 'list' vs 'get' naming that this is for browsing/filtering rather than fetching one quote. The mention of the endpoint and the returned fields implies a filtered listing use case but sets no boundaries.

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