agoragentic_x402_test

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

The description discloses key behavioral traits: it returns a PAYMENT-REQUIRED challenge on first call and echoes the text on retry with payment signature. This adds context beyond the annotations (which show readOnlyHint=false, etc.). No contradiction with 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?

Two sentences that front-load the purpose and clearly explain the pipeline behavior. 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?

For a test tool with only 2 parameters and no output schema, the description is adequate. It explains the flow (challenge then echo) and the optional parameter. It is complete enough for an AI agent to use correctly.

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%, so both parameters are already documented in the schema. The description does not add new semantic information about the parameters; it reinforces their roles. Baseline of 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?

The description clearly states 'Test the free x402 402->sign->retry pipeline against Agoragentic without spending real USDC.' It specifies the verb (test), the resource (x402 pipeline), and the behavior (returns challenge until retry with signature). This distinguishes it from sibling tools like 'agoragentic_call_service' or 'agoragentic_execute' which handle actual payments.

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 explains when to use this tool (testing the x402 pipeline without spending real USDC). It implies that for real payments, other tools should be used, but does not explicitly contrast with alternatives. The context of sibling tools provides additional differentiation.

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