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

Annotations already establish the safe read-only, idempotent, closed-world profile, so the bar is lower; the description still adds useful behavior: public-only visibility, an 18-per-page cap, and that invalid/inactive taxonomy yields a tool error. It could go further on what the error payload or result shape looks like.

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, front-loaded with the core action and scope, with the error behavior appended where it is useful. Nothing is redundant.

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, the description should close more gaps for a five-parameter tool; the pagination cap and error behavior help, but the unmentioned q and sort semantics leave an agent guessing about filtering and ordering.

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 parameter meaning, yet two of the five parameters (q and sort) are never mentioned. It only gestures at kind/slug and the page size, leaving the search term and the newest/popular/name ordering options undocumented.

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?

Specific verb and resource ('Browse public products') plus a clear scoping constraint ('in one active category or tag'), which implicitly separates it from the sibling search_products. It stops short of naming the sibling explicitly, so it earns a 4 rather than a 5.

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?

Usage is implied by the taxonomy-scoping phrase, but there is no explicit statement of when to prefer this over search_products or get_product. The note about unknown/inactive taxonomy is a failure mode, not selection guidance.

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