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

Annotations already declare readOnly, idempotent, closed-world, non-destructive, so the safety profile is covered. The description adds one genuinely useful behavioral note — that results are reference material rather than order-specific commitments — but says nothing about ranking, matching semantics (full-text vs. topic browse), or what happens when query is empty, which matters for a search 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 sentences, front-loaded with the resource inventory and closed with the interpretive caveat — nothing is padded. The first sentence is a dense comma list, but every item adds discriminating information about the corpus.

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?

Four parameters with zero descriptions, two enums with unexplained domain-specific values, and an undefined acronym ("HTR") mean an agent cannot confidently construct a call. With no output schema there is also no compensating documentation of return shape, so the description would need to do much more than it does.

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 0%, so the description carries the full burden, and it does not. It never mentions the query string, the limit cap of 10, the 19-value topic enum, or the opaque family enum (knitting_tools / panels_and_surfaces / components_and_finished_goods). The content list loosely echoes some topic values (sample, inspection, shipping, calculator) but gives no guidance on how topic, family, and query combine.

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?

Names a specific verb ("Find") and enumerates the concrete resource types it returns: buyer guides, sample/inspection checklists, document scope, shipping guidance, calculators, case studies. An agent can form a clear picture of the result set. It stops short of distinguishing itself from the sibling search_products, so the guide-vs-product boundary must be inferred from the word "guides".

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?

There is no statement of when to reach for this tool versus search_products, get_product, or prepare_inquiry, and no exclusions or prerequisites. The trailing sentence constrains how to interpret results ("references, not order-specific promises") but that is a caveat on output, not usage routing.

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