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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so safety is covered. The description adds meaningful behavioral context beyond those fields: it explicitly does not create an account/order/report/charge and clarifies 'a quote request and an MCP connection are not purchases.' That is real value not present in the annotations.

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?

Front-loaded with the trigger condition and dense with concrete price points, with almost no filler. However it is essentially one very long run-on sentence that would be easier to parse as a short list of the price paths.

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 rightly explains what is returned (the specific quote paths and API availability), and annotations cover the safety profile, so an agent can call it confidently. It stops short of describing the response's shape or fields, which is a minor residual 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?

The tool takes zero parameters, so the baseline of 4 applies; there is nothing for the description to document beyond confirming it is a no-argument lookup.

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 specific resource (Scanverity pricing, products, ordering paths) and enumerates what it returns, so the agent knows exactly what comes back. It implicitly distinguishes from request_assessment via the 'does not create an account, order, report, invoice or charge' clause but never names the sibling tools explicitly.

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?

Gives clear triggering conditions ('Use this public tool when a user asks about Scanverity prices, products, access...or what to do without an approved customer account'), which is strong when-to-use guidance. It does not name alternative siblings (e.g. request_assessment) for when the user actually wants to order, leaving that routing implicit.

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