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

Annotations already establish readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds one genuinely behavioral fact beyond them — results are ordered 'most recent first' — but says nothing about how many products are returned, whether results are truncated or paginated, or when the list is empty.

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?

A single clipped sentence with the resource up front and the ordering constraint trailing — no filler, no restatement of the title 'Get product visibility'. Every clause carries 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?

With no parameters, no output schema, and safety already covered by annotations, the description is close to sufficient for invoking the tool. But because there is no output schema, it should say more about what each entry contains (identifier, name) and whether the list is capped — an agent cannot otherwise anticipate the response shape.

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 tool takes zero parameters, so per the baseline there is no parameter meaning for the description to add. The sentence correctly implies an unfiltered, unpaginated call with nothing to supply.

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 concrete resource ('Your products') and the specific attribute returned ('directory visibility (public/private)'), which is more informative than the bare tool name. It does not, however, distinguish itself from sibling list_products or get_product, so the agent must infer the division of labor from names alone.

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?

There is no explicit when-to-use guidance — nothing says why to pick this over list_products, search_products, or get_product. The possessive 'Your' hints at owned-vs-public scope, but that is inference, not guidance, and no exclusions or prerequisites are given.

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