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 genuine behavioral context beyond that: reviews are 'normalized', results are paginated one page at a time, and a web_id with zero reviews yields a legitimate zero-result rather than an error — a useful expectation-setting detail.

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?

Three tight sentences: return contents first, then identifier provenance, then the zero-result edge case. Every sentence earns its place and the most decision-relevant information 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 an output schema present, return values need no further explanation, and the description still summarizes them usefully. Combined with the zero-result behavior and identifier provenance, it is nearly complete; only pagination mechanics for the page parameter are left unstated.

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 must carry the load. It does explain web_id precisely (the same identifier as kohls_category's products[].web_id), but the page parameter is only implied by the phrase 'One page' with no guidance on numbering or defaults, leaving half the parameters under-specified.

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 and resource — 'One page of a Kohl's product's normalized customer reviews' — and enumerates the returned fields (title, text, rating, secondary ratings, reviewer info, dates, photo URLs). This clearly distinguishes it from siblings like kohls_category, which supply the web_id rather than the reviews.

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 establishes the precondition for use by explaining that web_id comes from kohls_category's products[].web_id, effectively routing the agent through the right sibling to obtain the identifier. It does not, however, state any when-not or alternative review sources, so it falls short of a full 5.

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