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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false, so the safety profile is covered. The description adds a useful behavioral detail: "New products are active immediately." However, it does not explain permissions, side effects, uniqueness behavior, or what happens to related inventory.

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 two sentences, front-loads the action, and contains no filler. Both sentences convey relevant information without repetition.

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 create tool with five undocumented parameters and no output schema, the description is too sparse. It covers purpose and immediate activation but omits parameter semantics, required project association, slug behavior, and any indication of what is returned.

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% for five parameters, and the description does not explain any parameter names or meanings. It does not clarify required fields like title and projectId, nor optional fields like slug, description, or externalCheckoutUrl.

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 uses a specific verb and resource: "Create a Replo-managed product," and adds scope with "for native product pages or checkout flows." It is clear what the tool does, though it does not explicitly differentiate itself from sibling tools like update_product, get_product, or find_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?

The phrase "for native product pages or checkout flows" implies when this tool is appropriate, but there are no explicit when-not conditions, prerequisites, or named alternatives such as update_product. Usage guidance is therefore present but only implied.

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