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

With no annotations, the description must fully disclose behavior, but it only states the basic function. It omits any mention of authentication needs, rate limits, idempotency, side effects, or return format. This is insufficient for a tool with no annotation support.

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 a single, well-structured sentence that immediately states the tool's core purpose and sorting behavior. Every word is necessary, and there is no superfluous information.

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?

Considering the lack of output schema and annotations, the description is too sparse. It fails to explain pagination behavior, what fields the response contains, error handling, or any constraints beyond the parameters. A more complete description would include common behavioral details.

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?

The schema has 33% description coverage, yet the description adds zero additional context for the three parameters. It does not explain 'page', 'page_size', or 'category' beyond their names and defaults. The category enum is already in the schema, so no added value.

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 clearly states the action ('Get'), the resource ('latest new arrivals on SAQ.com'), and the sorting ('sorted by arrival date, most recent first'). It effectively distinguishes this tool from siblings like 'get_coming_soon' or 'search_products'.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, limitations, or conditions under which this tool should be preferred over similar tools like 'search_products' or 'get_coming_soon'.

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