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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the content boundary (product pages excluded), which is genuinely useful scoping, but says nothing about authentication, rate limits, pagination, or result shape for what is a read/search operation.

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: coverage scope first, then the exclusion and the redirect. Every clause earns its place, and the most decision-relevant routing fact is front-loaded.

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 full parameter documentation in the schema, the description covers the essentials: what corpus is searched and which sibling handles the excluded case. It stops short of describing the return shape or ordering, which is a minor gap rather than a blocking one.

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%, and the schema already documents query, kind (with its eight values), and limit. The description's content list loosely echoes the kind values but adds no filtering syntax, formatting, or default behavior beyond what the schema states, 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?

The description states a specific verb (Search) and resource (published material), then enumerates the content domains covered: manufacturing, OEM/ODM, sampling, testing, wholesale, buyer guides, FAQ, glossary, comparisons. It explicitly names the sibling it is not (search_products) for product pages, so an agent can route without opening either schema.

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 an explicit exclusion (product pages are excluded) paired with the alternative tool to use instead (search_products). That is a direct when-not/when-instead statement, which is stronger than most search tools provide.

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