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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds genuinely non-obvious behavior: results are capped, handles are derived from URL paths, and tracking/variant query parameters are stripped. It stops short of mentioning pagination behavior or cache/rate characteristics.

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 tight sentences: the first front-loads the resource and scope, the second delivers the handle-derivation detail and the practical tie to quince_product. No filler, though the second sentence is dense with stacked clauses.

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 annotations cover the safety profile. The description supplies the key behavioral and semantic context (capping, handle derivation, query-param stripping, product chaining); only explicit alternative-routing guidance is missing.

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 coverage is 100%, so both parameters are already documented, making 3 the baseline. The description adds meaning for the 'type' parameter by explaining the products case and handle derivation, but says nothing about 'limit' beyond what the schema already states.

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 specific resource (capped URL entries from Quince's own sitemaps) and a filter (matching the requested type), plus the derived 'handle' field, so an agent knows what it returns. It implies but does not explicitly name the sibling it pairs with (quince_sitemaps) or contrast with it, so it falls just short of full sibling differentiation.

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?

It gives a concrete usage bridge -- for type=products the handle is directly the value quince_product expects -- which tells the agent how to chain tools. However, there is no explicit statement of when to choose this over quince_sitemaps or other Quince tools, and no exclusions, so guidance is implied rather than complete.

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