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

No annotations are present, but the description flags the action as high-risk and requires explicit user confirmation—critical behavioral context. It also notes the return of payment information. Could additionally disclose irreversibility or charging side effects, but the warning is substantial.

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?

Two sentences, front-loaded with purpose and risk warning. No fluff or repeated schema info.

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 an 11-param tool with nested objects and no output schema, the description captures the core purpose and high-risk context. It could elaborate on the payment information return format, but schema covers parameters adequately.

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 has 100% parameter description coverage, so the description adds no param-specific value. 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?

Clear verb+resource: 'Create a ManaBuy order' and adds 'return payment information'. Distinguishes from siblings by being the only order-creation tool among read/quote tools.

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 states 'high-risk action: call it only after explicit user confirmation', providing a strong when-not-to-call condition. Doesn't name alternatives like quote_order, but the confirmation requirement is clear guidance.

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