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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered; the description adds meaningful extras: taxes are included, the price matches what will actually be charged, a confirmationToken is returned, and the required orders:quote permission. No contradiction with the read-only annotation.

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 front-loaded sentence states purpose, output, and the downstream call, followed by two compact parentheticals for permission and prerequisites. Nothing is wasted.

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?

No output schema exists, and the description partially compensates by naming confirmationToken and stating that prices include taxes. It omits the shape of the price breakdown and any pagination/expiry detail for the token, but overall an agent has enough to call it 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 67% and the description contributes no parameter-level detail (items, country, province are never mentioned). The schema carries the weight via enum/default descriptions, so 3 is the appropriate baseline.

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?

Specific verb+resource (prices/quotes a cart) with the exact output named (confirmationToken). It explicitly distinguishes itself from the sibling gpucloud_create_order by explaining the token hand-off, so an agent can route between quote and order without opening a schema.

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?

Implies the workflow clearly: quote first, then feed the token to gpucloud_create_order with the same items. It also states a prerequisite (free GPU Cloud account + MCP key). It stops short of an explicit when-not or a pointer to the related gpucloud_quote_server sibling for single-server quotes.

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