create_quote

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, covering safety traits. The description adds that it returns exchange rate, fees, and delivery estimate, which is useful context, but does not disclose side effects, persistence of the quote, or permission requirements. With annotations present, this is adequate though not rich.

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 sentences, front-loaded with the main purpose, and every sentence conveys essential information. It is concise and well-structured without unnecessary repetition.

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?

Given there is no output schema, the description appropriately summarizes return values (exchange rate, fees, delivery estimate). It also clarifies the mutually exclusive amount input. However, it does not mention whether the quote is temporary or persistent, nor any side effects, though annotations mitigate some gaps. Overall, it is fairly complete for this tool's complexity.

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 input schema has 100% parameter description coverage. The description reinforces the 'sourceAmount OR targetAmount (not both)' rule, which is already embedded in the schema's property descriptions, so it adds marginal value beyond the schema.

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 states the tool creates a quote for a money transfer, with a specific verb and resource. It also mentions the key input constraint and outputs. However, it does not distinguish itself from sibling tools like get_quote or get_temporary_quote, so it lacks sibling differentiation.

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 no guidance on when to use this tool versus alternatives such as get_quote or get_temporary_quote. It implies use for creating a quote but does not state exclusions or compare with other quote-related tools, leaving the selection decision underspecified.

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