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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the write/non-destructive profile is covered structurally. The description adds almost nothing beyond this — it doesn't explain reversibility, what happens to the product when hidden, or any auth/permission requirements, and its 'articles may feature' wording is loosely aligned with the active/hidden enum rather than clarifying it.

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 short sentence with no wasted words, but the brevity reflects under-specification rather than disciplined conciseness. It is front-loaded but too sparse to earn a higher mark.

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?

For a mutation tool with four required, undocumented parameters and no output schema, the description is far too thin. It neither explains parameter roles nor confirms the effect of the operation, leaving significant gaps an agent would need to call this correctly.

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% across 4 required parameters (projectId, siteId, productId, status), so the description carries the full burden of explaining them. It mentions none of them explicitly, offering only the vague phrase 'whether articles may feature a product' which does not clarify the meaning of productId, siteId, projectId, or the status enum values.

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 names a specific verb ('set') and resource ('product'), but 'Set whether articles may feature a product' is a vague framing that doesn't clearly convey the tool's actual behavior of toggling a product's visibility to active/hidden. The title ('Show or hide a catalog product') is clearer than the description itself, and no differentiation from siblings like update_product or delete_product is given.

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 indication of when to use this tool versus update_product, create_product, or list_products, nor any prerequisites or context. The agent must infer intended usage entirely from the name and title.

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