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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action is to quote, which suggests a read-only pricing operation, but it does not disclose whether any side effects occur, whether a purchase is initiated, what the response contains, or whether authentication or rate limits apply. The team pack explanation adds product context but not behavioral insight.

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 core action is front-loaded, and the second sentence provides necessary product detail without repeating schema information. Every sentence 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?

The tool has four optional parameters and no output schema, so the description should at least indicate what a quote contains or that the call is non-committal. It does not describe the return shape or any follow-up steps. However, the operation is relatively simple and the description defines the scope well enough for basic invocation, making it adequate but with clear gaps.

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 100%, so the schema already documents all four optional parameters. The description adds context about the Team Migration Pack, which helps map product_id to the intended product, and it restates the USD currency constraint. However, it does not add meaning for locale or buyer_country beyond what the schema already provides, so the baseline 3 is appropriate.

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 states a specific verb ('Quote'), a specific resource ('Bring Your AI lifetime license or Team Migration Pack'), and a specific currency ('USD'). It also clarifies what the Team Migration Pack includes, which distinguishes it from other products. This clear action-resource pairing differentiates it from sibling tools like start_checkout or list_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 description implies the tool is used when a quote for a lifetime license or team migration pack is needed, but it never explicitly states when to use it versus alternatives such as start_checkout or list_products. No exclusions or prerequisites are mentioned, so an agent must infer the appropriate context solely from the verb 'Quote'.

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