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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only the limit ceiling of 20, which is already in the schema, and says nothing about rate limits, whether the seed itself is excluded from results, or result stability. Adequate but thin given the low bar set by annotations.

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 compact sentences, front-loaded with the core action and followed by the routing hint. No filler or redundancy.

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 description covers the required seed handle plus its source. Minor gaps remain: nothing about whether recommended items are guaranteed distinct from the seed or how exhaustiveness behaves, but nothing essential is missing for a correct call.

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% and each parameter is documented in the schema (defaults, allowed values, max). The description restates intent's related/complementary behavior and the 20 cap without adding format or syntax detail beyond the schema, so the 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 (Fetch) and resource (recommended product items) scoped to a Cole Haan seed product handle. It clearly distinguishes itself from the catalog/seed siblings colehaan_product and colehaan_products, and names the two modifiers (intent, limit) that shape the result.

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?

Explicitly routes the agent: use colehaan_product or colehaan_products to find seed handles before calling this. That is clear upstream context, but there is no statement of when-not to use it (e.g., if you already have a product and just want details).

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