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

No annotations are present, so the description carries the transparency burden. It adds useful context such as '70,000+ products (11,060 live detail pages)' and mentions virtual proof pages, but it does not disclose behavioral nuances like how search matching works or any limitations. It's above the tautology level but not deeply transparent.

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 description is 4 sentences, front-loaded with the primary purpose, followed by scale and return details. The sentence about custom logo imprinting is slightly tangential but still relevant to the catalog. No waste or repetition.

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 no output schema and no annotations, the description explains returns (wholesale pricing, images, proof page links) and gives a sense of scope (70k+ products, 30+ categories). It lacks guidance on pagination or result interpretation but is reasonably complete for a search tool given the schema's parameter documentation.

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%, so the baseline is 3. The description does not add meaning to parameters beyond what the schema already provides—it only mentions the general catalog context. Schema entries like 'Text search on product title' and the brand enum already handle parameter understanding.

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 verb ('Search'), a specific resource ('POPS4 wholesale branded identity infrastructure catalog'), and enumerates what is returned (products with wholesale pricing, images, and proof page links). This clearly differentiates it from siblings like get_product (single item) and get_product_catalog (full catalog).

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?

The description implies usage for searching a large catalog but does not explicitly state when to use this tool vs alternatives like get_product or get_product_catalog. It provides context about scale and returns but lacks exclusions or explicit alternative recommendations.

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