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

No annotations are provided, so the description carries the behavioral disclosure burden. It states what the tool will present: flat one-time fee, no monthly costs, and full code ownership, while clarifying that exact quotes are out of scope. A return format is not described, but for a zero-parameter static information tool this is a minor gap.

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 concise sentences with no filler. The first sentence delivers the core pricing model, and the second adds the important custom-quote caveat. Every word earns its place.

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 no-parameter information tool with no output schema, the description provides the essential content and directs exact-quote requests to the quote form. It is complete enough for an agent to select and invoke the tool 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?

The tool has zero parameters, so the empty input schema leaves nothing to document. The description adds useful context about what the returned pricing model contains, which is sufficient.

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 clearly identifies the resource as BuiltToWinWeb pricing and specifies the key content: flat one-time fee, no monthly costs, full code ownership. It also distinguishes general pricing from per-project quotes, making the tool's purpose easy to identify.

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 description provides a clear boundary: exact quotes are per-project via the free quote form, implying this tool is for general pricing model information, not custom quotes. It does not explicitly name the request_quote sibling, but the guidance is clear enough for an agent to choose correctly.

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