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

Annotations already indicate this is not read-only and not destructive. Description adds that it returns an approval link and that a subsequent capture step is required. It does not elaborate on side effects, persistence, or rate limits, adding only marginal value beyond 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 concise sentences front-load the main purpose and return value, followed by currency support and next step. No wasted words.

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 9 parameters and no output schema, the description covers the essential two-step flow and mentions the approval link. It could benefit from describing the return structure more explicitly, but overall it is sufficiently complete for a simple payment creation tool.

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 100% of parameters with descriptions. The overall description adds context about currency default (BRL) and the purpose of the return link, but does not explain parameter semantics beyond what the schema already provides.

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?

Description clearly states it creates a PayPal order and returns an approval link, specifying integration via ZuckPay. It distinguishes from the sibling capturePayPalOrder by indicating the next step after approval.

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?

Explicitly mentions when to use (to create an order) and directs to capturePayPalOrder after approval. Does not explicitly state when not to use, but the presence of sibling tools for other payment methods (e.g., createPixCharge, createSpeiCashin) implies context.

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