x402_address

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

The verb 'Get' signals a read-only operation, but the description does not explicitly state that this tool has no side effects, nor does it disclose potential outcomes such as an error if no address is configured. Since no annotations are provided, the description carries the full burden but offers minimal behavioral detail; however, the absence of mutation is reasonably implied.

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 a single, front-loaded sentence with no redundant words. Every word contributes to the purpose, and the structure is clean and efficient.

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 a zero-parameter getter with no output schema, this description is nearly complete: it states exactly what is returned (the configured address). It could be marginally enhanced by noting that the address comes from the x402 configuration, but the current wording is sufficient for a tool of this simplicity.

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 zero parameters, so there is nothing to explain. This matches the baseline of 4 for a no-parameter tool, and the description does not need to add parameter semantics.

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 uses a specific verb ('Get') and a clear resource ('your configured x402 payment wallet address'), making its purpose immediately obvious. The word 'configured' helps distinguish it from siblings like x402_get_wallet_address by implying a user-specific stored address.

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. It does not mention any exclusions, prerequisites, or conditions (e.g., 'use x402_config to set the address first'), leaving the agent without decision support among many x402-related siblings.

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