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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so safety and repeatability are covered. The description's added value is the inventory of returned fields, which is genuinely useful context for a tool with no output schema. It does not disclose auth/scope requirements or error behavior, so it goes slightly beyond the annotations but not far.

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?

One compact sentence with zero filler, and the resource is front-loaded before the field enumeration. It is technically a noun-phrase fragment rather than a full statement of action, which is the only structural weakness.

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 output schema, the description correctly does the work of describing the returned payload, and the single input parameter is fully documented in the schema. For a simple read-only getter this is nearly sufficient; only the lack of when-to-use context leaves a small gap.

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?

There is a single parameter with 100% schema description coverage, and the schema already explains it references list_products. The description adds nothing about the parameter. Baseline 3 is appropriate when the schema carries the full semantic load.

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 the resource ('a hosted product') and enumerates the specific data it exposes (setup status, site address, allowed origins, help center slug/address, custom domains, GitHub connections), which separates it from create_product and update_product. It never states a retrieval verb, but the title supplies 'Get' and the field list makes the resource unambiguous. Missing is any explicit contrast with the nearest sibling list_products (one vs. many).

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 on when to call this versus list_products or get_setup_status, and no prerequisites or follow-up actions are mentioned. The only routing hint ('Product id from list_products') lives in the schema, not the description, so the description itself offers no usage context.

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