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

With no annotations, the description carries the full disclosure burden. It does state the operation is read-only, exhaustive, and paginated ('Pages through'), which is useful. However it omits return shape, whether unpublished products exist, authentication or rate-limit behavior, and how paging interacts with the large offset range.

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 tightly written sentences, front-loaded with the core purpose and scope. Each sentence adds distinct value: scope, contents, and filter guidance. No filler.

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?

No output schema, no annotations, and 0% parameter coverage mean the description should carry more. It is adequate for invoking the tool but leaves the agent without knowledge of the response shape, default page size, or what 'exhaustive' implies for cost across a 500-item-max page.

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 compensate. It adds real meaning for entity_type by tying 'grouped' and 'single' to the completeness/filtering intent, and 'Pages through' hints at limit/offset paging. But the limit default/max and offset semantics are left entirely to the schema.

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?

States a specific verb and resource (list/read the full product registry), plus the exact scope: every published WooCommerce product, including grouped models and standalone/exact products. It explicitly contrasts with searching, so an agent can distinguish it from search_products 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?

Gives a clear use case (catalog synchronization) and an exclusion: don't approximate completeness from search. It also names the filter values that dispatch the tool. It stops short of explicit when-not conditions or pointing at sibling list tools like list_product_groups.

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