x402_place_order

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

With no annotations, the description carries full burden. It discloses response structure (status, headers, body, original request) but omits side effects, financial implications, or order placement behavior hinted by the name. The description presents a benign HTTP call while the name suggests a mutating financial action, which is misleading.

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 primary purpose, and contains no redundant information. It is concise and well-structured.

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 description enumerates return values but fails to address the broader payment/order context, error handling, or integration with sibling x402 tools. Given the complexity implied by the name and sibling set, it is incomplete and leaves significant operational 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 coverage is 100%, with all parameters (url, body, method) described including the method enum. The description adds no additional parameter meaning beyond the schema, so it meets the baseline for high schema coverage but doesn't elevate understanding.

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 it sends an HTTP request and returns complete response details, which is a specific verb+resource. However, it is misaligned with the tool name 'x402_place_order', which implies a business order placement rather than a generic HTTP client, and it doesn't distinguish itself from payment-focused sibling 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?

It provides a general usage context ('Use this for any HTTP request where you need full response details') but no explicit when-not-to-use guidance or alternatives. It doesn't explain how this tool relates to siblings like x402_submit_payment, leaving the agent without clear selection criteria.

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