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

Annotations already indicate non-read-only, non-destructive, and idempotent. The description adds important behavioral context: creating a quote does not create a transaction or move funds, and the quote is time-limited (ten-minute). No contradiction with 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?

Three short sentences, front-loaded with the use case, and each sentence adds a distinct piece of information: when to use, what it does, and what it does not do. No redundancy.

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 a complex nested job schema and no output schema. The description explains the quote's purpose and side effects but does not describe the return value, how the quote is consumed by sibling tools like settle_checkout, or lifecycle expectations. Given the complexity, it is minimally adequate but not comprehensive.

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 covers only idempotencyKey with a description; buyerAddress and job lack top-level descriptions. The description indirectly references 'paying Base wallet' and 'exact content' to hint at the purpose of buyerAddress and job, but does not explain idempotencyKey or provide field-level guidance. This partially compensates for low schema coverage but leaves gaps.

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 explicitly states the tool creates a quote by validating a QA job and binding it to content and a Base wallet, with a specific verb ('bind') and resource. It distinguishes from siblings focused on reporting or checkout settlement, and clarifies the tool does not transact.

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 gives a clear when-to-use context ('Use before delivering a structured AI report...') and implies the quote precedes delivery. It does not explicitly name alternatives or when-not-to-use, but the usage scenario is unambiguous.

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